03BFF404FFE5FFD1FF660007BA7D7A91.taxon	discussion	DISCUSSION: The type series of H. confusus comprises 148 males and 132 females divided into 25 samples from eight different host-breeding localities, and 18 samples from birds taken at sea or found dead onshore. This extensive series shows that H. confusus is a morphologically uniform species, closer to H. kermadecensis (Johnston & Harrison, 1912) and H. turtur Edwards, 1961 than to all other species of Halipeurus. However, males of H. confusus differ from those two species by the genitalia having much longer and wider parameres, as well as a different configuration of the aedeagal sac (Fig. 57), and by the shape and chaetotaxy of the ventral terminalia (Fig. 28). In addition, the abdomen of male H. confusus is about 30 % longer than that of H. turtur. Females of H. confusus can be separated from those of H. turtur by their greater total length and by fine details of the terminalia. Females of H. confusus and H. kermadecensis are very similar and can only be separated by a detailed comparison of their terminalia. No other species of Halipeurus has suffered such an identity crisis as that of H. confusus. The confusion began with Edwards (1961: 151) when he described H. accentor based on a mixture of samples from four hosts, which he believed were two species of Pterodroma, each including two subspecies, as follows: “ Pterodroma leucoptera masafuerae ”, “ Pterodroma leucoptera hypoleuca ”, “ Pterodroma cookii nigripennis ” and “ Pterodroma cookii difilipianna ” (sic). These host taxa are now regarded, respectively, as the following four species: Pterodroma longirostris (Stejneger, 1893), Pterodroma hypoleuca (Salvin, 1888), Pterodroma nigripennis (Rothschild, 1893) and Pterodroma defilippiana (Giglioli & Salvadori, 1869) (see Jouanin & Mougin 1979: 76 and Dickinson 2003: 75). Two species of Halipeurus (H. leucophryna Timmermann, 1960 and H. theresae Timmermann, 1969) are known from three of those petrels (see Price et al. 2003: 187, 371) and a third, H. confusus, parasitises the fourth host species. Edwards’s type series of H. accentor contains all three Halipeurus species. I have examined the holotype male, the allotype female and one paratype male of H. accentor (all deposited in AMNH) from Pterodroma longirostris, the type host, and I have no doubt that they are conspecific with H. leucophryna. Further, I have examined a male-female pair of paratypes of H. accentor (deposited in MCZC) from Pterodroma defilippiana, which is also H. leucophryna. However, another male-female pair of paratypes of H. accentor (deposited in NHML) from Pterodroma nigripennis is clearly not H. leucophryna but H. confusus (see Material examined). Emerson (1972: 80) listed H. accentor as a junior synonym of H. leucophryna without any comment and without citing any material examined to justify his synonymy. Nevertheless, I agree with Emerson’s new synonymy, which left the Halipeurus from Pterodroma nigripennis unnamed. Timmermann (1965: 148) realised that both H. accentor and H. leucophryna had the same type host but he was not convinced that they represented the same species, hence he listed the former species under H. leucophryna as “ Syn.? H. accentor ”. Timmermann correctly pointed out the gross differences between the genitalia of those two species, as far as he could judge from comparing his H. leucophryna material against Edwards’s (1961: 140, fig. 5 R) illustration of H. accentor genitalia, but he was cautious and did not confirm the synonymy because he had not compared the types. After examining the types of H. accentor, I can only conclude that the figure of the male genitalia depicted by Edwards for H. accentor (1961: 140, fig. 5 R) was drawn from a paratype male from Pterodroma nigripennis, and is therefore H. confusus. The male genitalia of H. leucophryna is, as stated and illustrated by Timmermann (1965: 149, fig. 89), very slender, thus differing significantly from the genitalia of H. confusus (Fig. 57). Amerson & Emerson (1971) listed many records of lice collected by the Pacific Ocean Biological Survey Program (POBSP) carried out by the Smithsonian Institution in the Pacific Ocean from 1963 to 1969. I have been able to examine some of the Halipeurus collected by the POBSP (see Material examined) but I found them to be mostly misidentified. The problem is that not only the lice but also the petrel hosts were incorrectly identified (G. E. Watson pers. comm. 1982, J. A. Bartle pers. comm. 1982). Thus, records of H. theresae listed by Amerson & Emerson (1971: 4) under Pterodroma hypoleuca actually refer to two species: H. theresae from Pterodroma hypoleuca and H. confusus from Pterodroma nigripennis. Similarly, records of H. leucophryna listed under Pterodroma cooki cooki (sic) in Amerson & Emerson (1971: 5) are a mixture of H. leucophryna and H. confusus, but none of them were from Pterodroma cookii: the hosts involved were Pterodroma longirostris and Pterodroma nigripennis. Another incorrect host-louse record is that of H. pelagicus under Pterodroma cooki cooki (sic) in Amerson & Emerson (1971: 5): the lice are again H. confusus and the host Pterodroma nigripennis. My examination of samples from Norfolk Island identified by Nelson (1969), those from the Kermadec Islands published by Watt (1971), and specimens collected by the POBSP reported by Amerson & Emerson (1971) (see Material examined), confirm that the entries I have listed above in the synonymy of H. confusus are correct.	en	Palma, Ricardo L.

03BFF404FFE1FFDCFF660619BE9B7B8C.taxon	discussion	DISCUSSION: My examination of the 32 males and 41 females of H. pricei listed above shows no consistent morphological or size differences associated with the Halipeurus on any of the four hosts. The uniformity of the four populations of H. pricei is not unexpected considering the close relationship of its host taxa, which have been variously treated as full species or subspecies. Pterodroma brevipes was originally described as a full species, then treated as a subspecies of Pterodroma leucoptera for some years (Jouanin & Mougin 1979: 78, Watling 1986), and now is considered a full species by most authors (e. g. BirdLife International 2000: 56; Watling 2001: 186; Bretagnolle & Shirihai 2010), but as a subspecies of Pterodroma leucoptera by others (e. g. Dickinson 2003: 75). Although in this paper I follow the bird nomenclature in Dickinson (2003), I have made an exception with this group of Pterodroma taxa and have adopted the taxonomy used by the Ornithological Society of New Zealand Checklist Committee (2010) and Bretagnolle & Shirihai (2010). Among the Halipeurus males with a very short sixth abdominal segment — i. e. all species except Halipeurus marquesanus (Ferris, 1932), H. heraldicus Timmermann, 1960 and H. noctivagus Timmermann, 1960 — Halipeurus pricei belongs to a group of small species with slender genitalia, thin parallel parameres, and without pigmented aedeagal sclerites. They are: Halipeurus bulweriae Timmermann, 1960; H. falsus falsus Eichler, 1949; H. falsus pacificus Edwards, 1961; H. forficulatus Edwards, 1961; H. leucophryna; H. spadix spadix Timmermann, 1961 and H. spadix subclavus Timmermann, 1961. However, males of H. pricei can be distinguished from males of all of those species / subspecies by a number of characters, especially the short length of its parameres (see Tables 1 and 2), the shape of the clypeal signature, the shape and chaetotaxy of the ventral terminalia, and the length / width ratio of the head. As is the case with most Halipeurus species, females of H. pricei are much more difficult to separate than males; however, a detailed comparison of the shape of the clypeal signature and of the shape and chaetotaxy of the last two abdominal segments allows morphological separation of H. pricei females from those of the species mentioned above.	en	Palma, Ricardo L.

03BFF404FFEFFFDEFF6604EBBB0378B5.taxon	discussion	DISCUSSION: Morphologically, Halipeurus atlanticus is extremely similar to H. procellariae (J. C. Fabricius, 1775) recorded from five species of Pterodroma (Price et al. 2003: 188). Males only differ in details of the genitalia, and females are indistinguishable at present. However, molecular analysis has shown that they are not as closely related as their morphology would indicate. Values calculated as percentage sequence divergence between H. atlanticus (ex Pt. madeira) and Halipeurus procellariae (ex Pt. lessonii) are 12.7 – 13 % for the 12 S gene, and 14.5 % for the COI gene (Joseph Hughes pers. comm. 2007). Furthermore, Hammer et al. (2010) have found that H. procellariae and H. consimilis Timmermann, 1960 are sister species, and that H. atlanticus (as H. sp GLA 959) is sister to these two taxa. However, the phylogenetic trees in Hammer et al. (2010: 1113) for this clade show that bootstrap support and Bayesian posterior probabilities are low for these relationships. Therefore, morphological data may still be showing the true relationship between H. atlanticus and H. procellariae as sister species. Recent research by Jesús et al. (2009) on the phylogeny of the two subspecies of Pterodroma feae (Salvadori, 1899) and Pt. madeira shows that these species are more closely related to each other than to other North Atlantic species such as Pt. cahow and Pt. hasitata (Kuhl, 1820). Considering that both Pterodroma feae deserta (Mathews, 1934) and Pt. hasitata harbour Halipeurus theresae Timmermann, 1969 (Zonfrillo 1993), the presence of H. atlanticus on Pt. madeira and Pt. cahow is incongruent with the phylogeny of its hosts.	en	Palma, Ricardo L.

03BFF404FFEDFFDBFF6607F8BB627F3E.taxon	discussion	DISCUSSION: The type series of H. pelagodromae comprises 84 males and 95 females divided into 21 samples from six different host-breeding localities, plus several samples from birds taken at sea or found dead onshore. The type series together with non-types from all the other host subspecies show that, although some dimensions are wide ranging (see Table 1), H. pelagodromae is morphologically a uniform species, and close to H. pelagicus. Both sexes of these two species can be separated by the shape of the preantennal region of the head (compare Figs 22 and 24 with Figs 23 and 25 respectively) and the clypeal signatures (compare Fig. 6 with Fig. 7). Males can be further distinguished by the shape of their last abdominal segment and the length of distal ventral setae (compare Fig. 32 with Fig. 33). The female ventral terminalia of H. pelagodromae and H. pelagicus are very similar, but still distinguishable in some details (compare Fig. 47 with Fig. 48). Although the total body lengths of the two species are very close in both mean values and ranges, the head of H. pelagodromae is, on average, wider and longer than that of H. pelagicus in both sexes (Table 1). However, head length / head width ratios are higher for H. pelagicus (males 2.4; females 2.1) than for H. pelagodromae (males 2.2; females 1.9) in both sexes. The overall shape of the male genitalia of H. pelagodromae is extremely similar to that of H. pelagicus; although ranges of lengths of parameres overlap completely, the mean value for H. pelagicus is 10 % longer than for H. pelagodromae (Table 1). Percentage sequence divergence between Halipeurus pelagodromae and H. pelagicus (ex Oceanodroma castro) calculated for genes 12 s and COI are 2.183 % and 5.026 % respectively (Vincent S. Smith pers. comm. 2007). Although those values are not high, they support the separation of the Halipeurus population from Pelagodroma marina into a taxon different from H. pelagicus. Considering that there are also morphological differences in both sexes, albeit not marked, I am confident in regarding this new taxon as a full species.	en	Palma, Ricardo L.

03BFF404FFE8FFDBFF660044BBA97B34.taxon	discussion	DISCUSSION: Halipeurus vincesmithi has closer morphological affinities with H. raphanus, H. pelagicus, H. pelagodromae and H. nesofregettae than with all other species of Halipeurus. Those affinities are not surprising considering that its host, Oceanodroma matsudairae, and all the hosts of the four species mentioned above belong to the storm petrel family Hydrobatidae. Halipeurus vincesmithi is easily distinguished from H. pelagicus, H. pelagodromae and H. nesofregettae by its much greater length and width in both sexes (Table 1), by robust male antennae, by unique male genitalia (compare Fig. 58 with Figs 59, 63), and by the chaetotaxy of the ventral terminalia in both sexes (compare Fig. 34 with Figs 32, 33, 35 for males, and Fig. 49 with Figs 47, 48, 50 for females). Further, males of H. vincesmithi can be separated from males of H. raphanus by the shape of the clypeal signature, ventral terminalia and genitalia (compare Figs 8, 34, 58 with Figs 10, 36, 60 respectively), while females can be distinguished by the shape of the clypeal signature (compare Fig. 8 with 17), and the length of the terminal pair of peg-like setae in addition to the shape plus chaetotaxy of the subgenital plate (compare Fig. 49 with 52).	en	Palma, Ricardo L.

03BFF404FFF5FFC1FF6602C4BA5A7CE6.taxon	discussion	DISCUSSION: Comparison of the lectotype of Halipeurus angusticeps (Fig. 38) against each of the holotypes of Halipeurus sawadai and of Halipeurus angusticeps fosteri shows that they are all conspecific, and so are all other male specimens listed above under material examined. Also, female paralectotypes of H. angusticeps (e. g. Fig. 39) are conspecific with paratypes of both H. sawadai and H. angusticeps fosteri, as well as with all other females listed above under material examined. The identity of the type host of H. angusticeps — certainly not its natural regular host — has contributed to the proliferation of junior synonyms. I have never collected a Halipeurus louse from Procellaria cinerea, and neither did Edwards (1961: 136) who carefully examined “ … almost 75 museum skins ... ” without finding any specimen. In fact, no species of Procellaria harbours any Halipeurus species as regular natural ectoparasites (Pilgrim & Palma 1982: 11; Price et al. 2003: 371). There are two possible scenarios to explain the artificial association of Piaget’s type series of H. angusticeps with Procellaria cinerea. One is that the type series was somewhat accidentally transferred from a specimen of C. leucomelas to one of P. c i n e re a before or after the latter became a skin in the collection of the Leiden Museum. After all, cross contamination of lice among skins kept in museum collections is not unusual, as it has been the case of other Piaget louse material (see Clay 1973: 218). However, I believe the most likely explanation is a misidentification of the original bird from which the Piaget type series of H. angusticeps originated. Further evidence of a host misidentification can be found in the Piaget (1880: 501) designation of Procellaria cinerea as the type host for his new species “ Menopon longithoracicum ” (now Austromenopon longithoracicum (Piaget, 1880 )). Price & Clay (1972: 497) failed to find any additional specimen of A. longithoracicum from its type host, but they examined four other samples of this louse species from Calonectris leucomelas (as Puffinus leucomelas). I have examined five additional samples (21 lice) of A. longithoracicum from C. leucomelas. In my opinion, a cross contamination of all the type material of both H. angusticeps and A. longithoracicum (a total of at least 15 specimens) from one or more C. leucomelas to one or two P. c i n e re a is far less likely than a misidentification of the type host (s). Nakagawa (1959) compared his Halipeurus material from Calonectris leucomelas against specimens of Halipeurus diversus (Kellogg, 1896), H. mirabilis (Thompson, 1940) and H. abnormis (Piaget, 1885). Indeed, those three species are very different from H. angusticeps in several features, especially the terminalia and genitalia of the males. However, Nakagawa (1959) failed to compare his material against authenticated specimens of H. angusticeps, perhaps misled by the fact that the type host of this latter species is not a species of Calonectris. From my examination of the types of H. sawadai and the clear illustrations published by Nakagawa (1959: 388), I have no doubt that H. sawadai is a subjective junior synonym of H. angusticeps. The rationale behind the Edwards (1961) decision to segregate the Halipeurus from Calonectris leucomelas as a new subspecies of H. angusticeps is not entirely clear. Firstly, he was not aware of the Nakagawa (1959) paper, otherwise he may not have published his new taxon. Secondly, Edwards (1961: 137) stated that H. a. angusticeps “ … is very closely related to that parasitizing Puffinus leucomelas, … ” and, thirdly, he believed that there may have existed a local population of Calonectris diomedea parasitized by H. a. angusticeps, despite the fact that in his own experience all subspecies of C. diomedea were parasitized by Halipeurus abnormis only. After examining 30 samples of Halipeurus from as many individuals of the three subspecies of C. diomedea, I have not been able to find a single H. angusticeps: all specimens are H. abnormis. On the other hand, I have examined 16 samples of H. angusticeps from C. leucomelas (see above). Having examined three males and four females of Piaget’s type series of H. angusticeps, Edwards (1961) distinguished his subspecies H. angusticeps fosteri from H. angusticeps angusticeps on the basis of very tenuous characters, such as size, degree of sclerotization, the shape of the posterior margin of the male sternite 9 + 10, and the curvature of the right paramere in the male genitalia. From my examination of 48 males of H. angusticeps from Calonectris leucomelas and 5 males from Piaget’s type series, I found that the shape of the posterior margin of the male sternite 9 + 10 is quite variable as shown in Fig. 40 a – g. Similarly, the curvature of the right paramere in the male genitalia (Fig. 62) is likely to vary among individuals because that paramere is very thin and liable to bend during the slide-mounting process. Therefore, I have no hesitation to propose that H. angusticeps fosteri is an objective junior synonym of H. sawadai as well as a subjective junior synonym of H. angusticeps sensu stricto.	en	Palma, Ricardo L.

03BFF404FFF1FFCEFF66067EBB427989.taxon	discussion	DISCUSSION: Timmermann’s (1961) description of Halipeurus subclavus is very brief and without illustrations, but includes measurements and a comparison with H. spadix (as H. intestatus), which he regarded as the closest species. Besides the holotype and allotype, no additional specimens of H. subclavus have been reported in the literature. My examination of the types of H. subclavus (Figs 66 – 67) shows that they are extremely similar to H. spadix; hence, the logical conclusion would be to demote H. subclavus to a junior synonym of H. spadix. However, considering that the dimensions of H. subclavus — including many specimens from three other hosts — are consistently smaller in both mean values and ranges than those of H. spadix from five hosts (see Table 2), I believe that regarding both taxa as subspecies of H. spadix is the best option to show that, despite being morphologically very close, they are still different and identifiable as separate entities. There are a few specimens of H. spadix spadix from Puffinus huttoni that slightly overlap in head dimensions with specimens of H. spadix subclavus from P. l h e rminieri bailloni and P. g a v i a. However, they can be clearly separated by their total length in both sexes as well as by paramere length in males (Table 2). Timmermann (1961: 412) commented that studies of larger series than those available to him might show that his three new species (H. spadix, H. intestatus and H. subclavus) would have to be considered as conspecific. Based on molecular data, Austin et al. (2004: 858) proposed that Puffinus lherminieri persicus and P. l h e r m i n - ieri bailloni should be regarded as subspecies of P. bailloni; the host distribution of Halipeurus spadix subclavus is congruent with that arrangement. Austin et al. (2004: 858) also concluded that Puffinus lherminieri nicolae should be synonymised with Puffinus lherminieri dichrous (as Puffinus bailloni dichrous). However, this latter synonymy does not agree with the distribution of Halipeurus lice on those hosts because a very different species, H. forficulatus, is the regular Halipeurus parasitising P. lherminieri dichrous in the Pacific Ocean (28 males and 28 females examined — including the holotype, the allotype and two paratypes of H. forficulatus — from nine hosts collected in eight localities). If the synonymy between P. l. nicolae and P. l. dichrous is correct, the Indian Ocean population of P. l. dichrous (known as P. l. nicolae) must have had its ancestral population of H. forficulatus replaced by H. spadix subclavus after a host switch from one of the other Indian Ocean subspecies of P. lherminieri. On the other hand, the presence of H. spadix subclavus on Indian Ocean birds, regarded as P. bailloni dichrous by Austin et al. (2004: 858), may in fact indicate that P. l. nicolae should not be synonymised with P. l. dichrous. Two other subspecies of Puffinus lherminieri have been described from the Indian Ocean: P. l. temptator Louette & Herremans, 1985 from the Comoro Islands, and P. l. colstoni Shirihai & Christie, 1996 from Aldabra Island (Dickinson 2003: 76). However, no lice have been recorded from those shearwaters yet.	en	Palma, Ricardo L.

03BFF404FFFBFFC8FF660624BB597B2C.taxon	materials_examined	The original description of Lipeurus languidus by Kellogg & Kuwana (1902: 475) was based on specimens collected from eight different host species. Kellogg (1906: 319) added four further hosts for L. languidus. Subsequent collections show that only two (Oceanites gracilis and Oceanodroma tethys) of those 12 hosts are natural and regular hosts for H. pelagicus (see material examined above). Hopkins & Clay (1952: 164) selected Oceanites gracilis as the type host for L. languidus. However, the specimen figured by Kellogg & Kuwana (1902: pl. 29, fig. 8) is a male from Oceanodroma tethys mounted on slide 1047 b (CISC), which was labelled as the lectotype by Theresa Clay at an unknown date. From the literature available, it appears that neither Clay nor anybody else published the designation of that lectotype. Therefore, as I agree with Clay’s informal proposal, I herewith designate the same male on slide 1047 b as the lectotype of L. languidus Kellogg & Kuwana, 1902. The female from the same host species on slide 1047 a (CISC), with the same data as the lectotype (see material examined above), is a paralectotype. Consequently, Oceanodroma tethys becomes the type host of L. languidus. The taxonomic purpose of this designation is to clarify the status of the type specimens and to fix the type host of L. languidus.	en	Palma, Ricardo L.

03BFF404FFF9FFCBFF6603ADBA017F76.taxon	discussion	DISCUSSION: The host species Pterodroma atrata, regarded as a junior synonym of Pterodroma arminjoniana heraldica for many years, has been recognised as a different species and separated from the latter (Brooke & Rowe 1996). Accordingly, Pt. atrata is a new host for Halipeurus heraldicus. The first record of Halipeurus heraldicus from Pterodroma arminjoniana arminjoniana was published by Vinson (1976) for Round Island, Mauritius, in the Indian Ocean. My examination of additional samples from the same locality (see above) agrees with Vinson’s identification. However, Pt. arminjoniana arminjoniana is also known to harbour Halipeurus kermadecensis on the island of Trindade, in the South Atlantic Ocean (see above). There is only one known case of two species of Halipeurus regularly parasitising one host species: that of H. procellariae and H. theresae (Timmermann, 1969) coexisting on individuals of Pterodroma magentae (Giglioli & Salvadori, 1869) in the Chatham Islands, as reported by Palma & Imber (2000). However, the situation with Pt. arminjoniana arminjoniana is different because there are two widely separated populations involved: one on Round Island, sympatric with other two Pterodroma species — Pt. neglecta and Pt. heraldica (see Hammer et al. 2010); and another on Trindade Island, sympatric with Pt. neglecta according to Imber (2004) but disputed by Hammer et al. (2010). Many louse samples from Pt. arminjoniana arminjoniana and one from Pt. neglecta collected at Trindade Island (see above) show that only H. kermadecensis is present there, while 23 samples from Pt. arminjoniana arminjoniana and five from Pt. neglecta (see above) collected at Round Island contain H. heraldicus only. Further sampling from those islands may still show that H. heraldicus and H. kermadecensis coexist within the same host populations, but the available evidence does not support that scenario (Brown et al. 2011, Hammer et al. 2010).	en	Palma, Ricardo L.

03BFF404FFF8FFF5FF660095BC417CE6.taxon	discussion	DISCUSSION: Edwards (1961: 143) identified five males and 13 females from Puffinus assimilis boydi (as “ Puffinus l’hermineiri boydi ”) ex Cape Verde Islands as Halipeurus diversus, while Timmermann (1961: 410) identified material from P. a. boydi as H. intestatus (= H. spadix spadix). My examination of three males and one female from P. a. boydi (see above) agrees with Edwards’s identification. This host-louse association was not included in Price et al. (2003). Edwards (1961: 146) identified two males and four females collected from Puffinus assimilis baroli near Porto Santo (Madeira Islands) as Halipeurus taxosetus, a species now regarded as a junior synonym of H. spadix spadix (see above). However, my identification of the specimens listed above under P. assimilis baroli, including some from Madeira Islands, show that they are Halipeurus diversus. Austin et al. (2004: 859, Table 3) placed Puffinus boydi and P. b a ro l i as subspecies of P. lherminieri based on a molecular phylogeny of the Puffinus lherminieri – assimilis complex. If the phylogeny proposed by Austin et al. (2004) is correct, and considering that these two petrels are parasitised by Halipeurus diversus, there must have been a host switch of H. diversus from one of its Atlantic Ocean hosts onto the ancestor of P. a. b o y d i and P. a. baroli, which replaced their ancestral Halipeurus spadix lineage.	en	Palma, Ricardo L.

03BFF404FFC6FFF6FF660070BCDC7DDE.taxon	discussion	DISCUSSION: Halipeurus raphanus is morphologically closest to H. vincesmithi, but they can be separated in both sexes by features of their clypeal signatures, genitalia and terminalia, as discussed above under H. vincesmithi. The figure of the male genitalia published by Timmermann (1961) is schematic and shows both parameres bent outwards, diverging from the longitudinal midline. Those diverging parameres can also be seen in Clay’s (1940) photograph of the male, which later became the holotype. Having examined eight males, including the holotype, I believe that the bent parameres of the holotype are artefacts of mounting, and that the usual configuration of the genitalia is with straight parameres as shown in Fig. 60. The description of H. raphanus was based on the holotype only. Since its type host, Oceanodroma macrodactyla, is probably extinct (Jouanin & Mougin 1979: 116, Dickinson 2003: 78), the probability of finding the female of H. raphanus was minimal until Marshall & Nelson (1967: 337) identified a sample containing five males, six females and five nymphs from a second host species, Oceanodroma homochroa. A third host species, O ceanodroma tristrami, has been identified in this paper, indicating that H. raphanus may still be found on more Oceanodroma species. Unaware of Marshall & Nelson’s (1967) record, Mey (1990: 71) listed H. raphanus as an extinct species together with seven other louse species. Like H. raphanus, at least one more of those presumed extinct lice has been recorded from an extant host different from the type host: Columbicola extinctus Malcomson, 1937, a species originally described from the extinct passenger pigeon Ectopistes migratorius (Linnaeus, 1766), has been found parasitising Columba fasciata Say, 1823 (Clayton & Price 1999: 681).	en	Palma, Ricardo L.

03BFF404FFC3FFFCFF66046CBD567E1E.taxon	discussion	DISCUSSION: The Timmermann (1960) description of Halipeurus fallacis is brief. Besides measurements and a comparison with H. bulweriae, which he regarded as the closest species, the description includes only one schematic illustration of the male genitalia. Apart from the two types, no additional specimens of H. fallacis have been reported in the literature and I have been unable to obtain any further specimen. Considering the rarity of H. fallacis and the paucity of specimens of Bulweria fallax available in collections, in addition to the difficulties to identify the host correctly (see Zonfrillo, 1988), I include additional illustrations of key features and habitus of both sexes of H. fallacis to facilitate the identification of this species. The petrel that became the type host of H. fallacis was originally identified and published by Alexander (1954: 489) as Pterodroma aterrima (Bonaparte, 1857), the Mascarene black petrel. That petrel was caught alive on board a ship, examined, measured, sketched, deloused and then released. Jouanin published his new species Bulweria fallax in 1955. Therefore, the host name attached to the lice that became the types of H. fallacis must have been changed to B. fallax at the NHML — albeit without a re-examination of the actual bird — prior to Timmermann’s (1960) publication. The identity of the petrel reported by Alexander (1954) as P. aterrima has been discussed by Jouanin (1957: 19). He admits that the descriptive data given by Alexander (1954) does not clearly fit either Pt. aterrima or B. fallax but, considering the geographical coordinates where the bird was captured, Jouanin (1957: 19) believes it was more likely B. fallax. Obviously, without a voucher specimen to support a definite identification, the identity of that petrel will remain forever in doubt. The uncertainty opens the possibility that the identity of the type host of H. fallacis may be in error. New louse collections from authenticated B. fallax and / or Pt. aterrima will be extremely useful to clarify that uncertainty.	en	Palma, Ricardo L.

03BFF404FFCFFFFDFF660526BB6F7A7E.taxon	discussion	DISCUSSION: Edwards (1961: 152) examined the two syntypes of Lipeurus diversus var. major, and qualified them as stragglers. I agree with Edwards in regarding those syntypes as stragglers, but I have not been able to examine them. In the course of my research on the lice from the Galápagos Islands, I have examined all specimens from those islands included in the Kellogg Collection held at CISC. Unfortunately, the syntypes of L. diversus var. major were not among them. Although Edwards (1961: 151) clearly indicated that H. (H.) intermedius was a nomen novum, he still designated a holotype, an allotype and paratypes for his new name. That designation contravenes Article 72.7 of the I. C. Z. N. (1999) Code, which states that the types of a nomen novum are the same as those of the preocuppied name it replaces. Therefore, the specimens listed above as “ types ” of H. (H.) intermedius are, in fact, not types. The Timmermann (1960: 330, fig. 16 b) illustration of the female last segment, taken from the allotype of H. noctivagus, has a clear angular indentation in its distal margin. However, all females listed above — identified as H. noctivagus according to males in the same samples — have terminalia with a slightly convex distal margin (Fig. 53). Timmermann (1965: 152) realised that females described by Edwards (1961: 138, fig. 4 S) from the same host were much larger than the allotype of H. noctivagus and that also differed from it in the shape of the distal margin; therefore, he admitted that the “ allotype ” belonged to another species, not H. noctivagus.	en	Palma, Ricardo L.
