Phalloceros caudimaculatus can be distinguished from P. anisophallos, P. megapolos, P. spiloura, P. reisi, P. buckupi, P. alessandrae, P. lucenorum, P. uai, P. pellos, and P. malabarbai by the female urogenital papilla straight along midline and located between the anus and the base of first anal-fin ray (vs. curved to the right, located laterally; border of the anal aperture in contact with the first anal-fin ray). Phalloceros caudimaculatus can be distinguished from P. tupinamba, P. leptokeras, and P. aspilos by (1) the female urogenital papilla straight along midline (vs. slightly left turned); (2) absence of a lateral ramus of the female urogenital papilla (vs. lateral ramus present); and (3) absence of hook in gonopodial appendix (vs. hook present). Phalloceros caudimaculatus can be distinguished from P. enneaktinos, P. titthos, P. elachistos, and P. harpagos by the absence of hooks in both halves of the gonopodial appendix (vs. hook present in both halves). Phalloceros. caudimaculatus is readily distinguished from P. heptaktinos by the absence of sexual dimorphism on number of dorsal-fin rays: males with 8 rays (very exceptionally seven) and females with seven rays (very exceptionally 8). Phalloceros caudimaculatus can be distinguished from P. ocellatus, P. mikrommatos, and P. leticiae by the lateral spot: P. caudimaculatus possesses a non-ocellated elliptical and vertically elongate lateral spot (rarely absent), whereas P. ocellatus, P. mikrommatos, and P. leticiae possess roundish to rounded and well-defined ocellated lateral spot.	en	Lucinda, Paulo Henrique Franco (2008): Systematics and biogeography of the genus Phalloceros Eigenmann, 1907 (Cyprinodontiformes: Poeciliidae: Poeciliinae), with the description of twenty-one new species.

Brown chromatophores scattered through whole body, more concentrated on dorsal portion, mainly on head, snout, opercle, and ventral surface of mandible. Lateral dark brown spot located on 14 th, 15 th, and 16 th or 16 th, 17 th, and 18 th scale of longitudinal series. Lateral spot covering approximately one and half scale on horizontal direction, and four or five scales on vertical, sometimes reaching dorsal and ventral profiles. Dorsal-fin membrane bearing dark band of chromatophores on distal border of dorsal fin. Dark band of chromatophores near dorsal-fin base, more intense in posterior rays. Pectoral, pelvic, and caudal fins hyaline. Dark brown line along R 3. Anal fin of females hyaline, except for patch of dark chromatophores on first three rays. Geographical variation. Color pattern of P. caudimaculatus varies considerably. The lateral spot is very frequently present, however, it may be absent. When present the lateral spot cover one to six transverse series of scales and less than one to three scales of the longitudinal series. Similarly lateral dark bars varies from inconspicuous to visible. It was not possible to correlate the color pattern to any geographical population for it varies among the specimens of the same population.	en	Lucinda, Paulo Henrique Franco (2008): Systematics and biogeography of the genus Phalloceros Eigenmann, 1907 (Cyprinodontiformes: Poeciliidae: Poeciliinae), with the description of twenty-one new species.

0D2787D41D48FFBADF125289C08CFCE8.taxon	discussion	Remarks. Among the original type series (Hensel, 1868: 362 - 364) only the seven specimens from lots ZMB 7425 and ZMB 7426 are surely syntypes of Girardinus caudimaculatus. It is not absolutely sure, whether the 25 specimens of lot ZMB 31496 belongs to the type series, since this number is secondarily based on an old label from the anatomical collection: “ No, 25202, “ Girardinus caudimaculata, C. da Serra “, - the remainder of the label is illegible (Paepke & Seegers, 1986). This is the collection of the former “ Institute of Anatomy of the Humboldt-University ” in the 19 th century, which used to belong to the Medical Faculty. This is due to the fact that human-anatomists were traditionally doing much research work on comparative anatomy of vertebrates. Thus, collected material was often divided between Zoological (Philosophical) Faculty with the Zoological Collection and the Medical Faculty. Only from approximately 1890 onwards the collections were reunited. But, apparently also R. Virchow, the famous pathologist working at the Charity Hospital at Humboldt-University, took over some of the original anatomical collection for study (Peter Bartsch in litt., 2000). As there is no apparent evidence that Hensel has not examined specimens from lot ZMB 31496, it should be more advisable to label them as syntypes. Whether oncoming evidences demonstrate that these specimens have not been syntypes, they will lose their type status. Reinhold F. Hensel was a German geographer and naturalist who lived in Brazil from 1863 to 1866. He collected in Rio Grande do Sul, especially in Porto Alegre and the German colonies to the north of that city (Papavero, 1973). Further, when Hensel returned to Germany, he published the results of his works in Brazil. In 1867 he published a large geographical report of the Província of São Pedro do Rio Grande do Sul (presently the Rio Grande do Sul State) including a map of the region (Hensel, 1867). Later, he dealt with descriptions of new vertebrate taxa, including Girardinus caudimaculatus (Hensel, 1868; 1870). The type-locality of G. caudimaculatus is mentioned as “ an der Costa da Serra bei S. Leopoldo in Brunnen und Gräben ” [= at the Costa da Serra at São Leopoldo in pounds and ditches]. The 1867 map shows that Costa da Serra corresponds to the area located in the south margin of the rio Cadeia and arroio Feitoria nearby the Encosta da Serra, and is delimited to the south by the rio dos Sinos drainage. This region currently corresponds to portions of the counties of São Sebastião do Caí, Estância Velha, and Ivoti. Although it is not possible to precisely locate the type-locality it seems very probable that Hensel would have collected his syntypes in the drainage of the rio Cadeia. One of 26 specimens of USNM 309769, is not P. caudimaculatus (is P. harpagos). The overall coloration of this individual is different from the remaining and P. harpagos is not sympatric with P. caudimaculatus. This specimen likely came from another lot by mistake.	en	Lucinda, Paulo Henrique Franco (2008): Systematics and biogeography of the genus Phalloceros Eigenmann, 1907 (Cyprinodontiformes: Poeciliidae: Poeciliinae), with the description of twenty-one new species.

0D2787D41D4CFFBCDD6D551AC07EFB2F.taxon	discussion	Remarks. The distribution of Phalloceros tupinamba is not continuous. The comparison between specimens from rio Macacu and rio Itamambuca has revealed no significant difference that could justify their recognition as distinct species. Until new evidence is available it is plausible to consider the distribution gap is probably due to the lack of collecting samples. Maybe new collecting efforts may reveal that the species also inhabits the coastal drainages between rio Macacu and rio Itamambuca.	en	Lucinda, Paulo Henrique Franco (2008): Systematics and biogeography of the genus Phalloceros Eigenmann, 1907 (Cyprinodontiformes: Poeciliidae: Poeciliinae), with the description of twenty-one new species.

Phalloceros elachistos can be distinguished from P. caudimaculatus, P. heptaktinos, P. ocellatus, P. mikrommatos, and P. leticiae by the possession of a hook in the gonopodial appendix (vs. hook absent). Phalloceros elachistos is readily distinguished from P. titthos by the absence of symphyseal papillae on mandible of large females (vs. symphyseal papillae present); and from P. enneaktinos by the possession of seven or eight dorsal-fin rays (vs. nine) (see remarks). Phalloceros elachistos can be distinguished from P. harpagos by the hook of gonopodial appendix, which is very small in adults, forming a minute lateral protuberance (Fig. 22) (vs. not forming a lateral protuberance – see remarks on P. harpagos description). In juveniles hook (usually) is absent or (rarely) minuscule. When present in juveniles hook never situated on the appendix corner (vs. present and located on the appendix corner). Juveniles never present skin covering the tip of appendix (vs. skin present). Distal half of appendix approximately as wide as (or slightly narrower than) proximal half (vs. narrower than proximal half).	en	Lucinda, Paulo Henrique Franco (2008): Systematics and biogeography of the genus Phalloceros Eigenmann, 1907 (Cyprinodontiformes: Poeciliidae: Poeciliinae), with the description of twenty-one new species.

Phalloceros harpagos can be distinguished from P. anisophallos, P. megapolos, P. spiloura, P. reisi, P. buckupi, P. alessandrae, P. lucenorum, P. uai, P. pellos, and P. malabarbai by the female urogenital papilla straight along midline and located between the anus and the base of first anal-fin ray (vs. curved to the right, located laterally; border of the anal aperture in contact with the first anal-fin ray). Phalloceros harpagos can be distinguished from P. tupinamba, P. leptokeras, and P. aspilos by (1) the female urogenital papilla straight along midline (vs. slightly left turned); (2) absence of a lateral ramus of the female urogenital papilla (vs. lateral ramus present); and (3) small and simple hook in gonopodial appendix (vs. large sickle like hook). Phalloceros harpagos can be distinguished from P. caudimaculatus, P. heptaktinos, P. ocellatus, P. mikrommatos, and P. leticiae by the possession of a hook in the gonopodial appendix (vs. hook absent). Phalloceros harpagos can be distinguished from P. titthos by the absence of symphyseal papillae on large females (vs. symphyseal papillae present); and from P. enneaktinos by the possession of seven or eight dorsal-fin rays (vs. nine) (see remarks). Phalloceros harpagos can be distinguished from P. elachistos by the hook of gonopodial appendix not forming a lateral protuberance (vs. very small in adults, forming a lateral minute protuberance – see remarks). In juveniles hook present and located on the appendix corner (vs. absent or (rarely) minuscule, when present in juveniles hook never situated on the appendix corner). Skin present covering the tip of appendix on juveniles (vs. skin absent). Distal half of appendix narrower than proximal half (vs. approximately as wide as or slightly narrower than proximal half).	en	Lucinda, Paulo Henrique Franco (2008): Systematics and biogeography of the genus Phalloceros Eigenmann, 1907 (Cyprinodontiformes: Poeciliidae: Poeciliinae), with the description of twenty-one new species.

Female urogenital papilla straight, located along midventral line and between anus and base of first anal-fin ray. Gonopodial appendix hook present (Fig. 28). Hook present in juveniles and located on appendix corner. Juveniles bearing skin covering tip of appendix. Distal half of appendix narrower than proximal half (Fig. 28). Color in alcohol. Eye black with greenish brown pupil. Ground Color brown, darker in upper half. Border of scales and subjacent skin replete with brown chromatophores, more concentrated at short distance from scale border, conferring reticulate pattern to body sides, mainly on upper half. Brown chromatophores scattered through whole body, more concentrated on dorsal portion, mainly on head, snout, opercle, and ventral surface of mandible. Lateral dark brown spot located between 16 th and 19 th scale of longitudinal series. Dorsal-fin membrane hyaline bearing dark band of chromatophores on distal border of dorsal fin and another near dorsal-fin base. Pectoral, pelvic, and caudal fins hyaline. Dark brown line along R 3. First three anal-fin rays of females covered of brown chromatophores forming patch of dark pigmentation. Intraspecific Variability. Variation in some morphological features (e. g. color pattern, hook on gonopodial appendix, measurements) has been found among distinct populations of P. harpagos during this revisionary study. Although differences may be found between some population pairs, it has not been possible to assign any of them as diagnostically distinct from the remaining populations. So, these populations are referred to as the same species. Degree of development of spots varies enormously, ranging from large and wide dark patch through small and narrow spot to no apparent mark. Variation on color cannot be associated as exclusive of any local population, for all variants are generally present in any of the populations. Alternatively the frequencies of each of the color “ types ” can be correlated to populations. Specimens from coastal drainages of Rio de Janeiro and São Paulo usually possess a roundish and short lateral spot, whereas southern populations in Santa Catarina usually show an elongate and wide lateral spot reaching dorsal and ventral profiles. Generally, specimens from the rio Paraná drainage possess a narrow and vertically elongate spot not reaching dorsal and ventral profiles. Individuals from some populations, e. g. rio Ribeira do Iguape, rio Iguaçu, present a very narrow and short lateral spot. Particularly, the population in the rio Ribeira de Iguape is an interesting case. This river is formed by the junction of rio Ribeira and rio Juquiá. Specimens from the rio Ribeira have a very narrow and short lateral spot, while specimens from the rio Juquiá possess a large and wide lateral spot. They are quite different from each other. Despite this, none of them can be distinguished from the bulk of P. harpagos, i. e. each can not be diagnosed or recognized as a distinctive species. Similarly, some specimens of the lower portions of rio Paraná differ from specimens from rio Paraguay. The former show narrow and vertically elongate lateral spot, whereas the later show large and roundish lateral spot. The two forms occur in the lower rio Paraná. This difference is congruent with differences in the depth of body and caudal peduncle of males. Again, both are clearly different from each other but cannot be distinguished from populations along the range of P. harpagos as a whole. Degree of development of the hook in the gonopodial appendix may also vary from a large hook to lateral expansion, especially in specimens from coastal drainages in southern Santa Catarina, which usually present a shorter hook on gonopodial appendix. At the moment, it is advisable to treat these differences as intraspecific variation, unless new evidences become available and allow the recognition of new diagnosable taxonomic entities.	en	Lucinda, Paulo Henrique Franco (2008): Systematics and biogeography of the genus Phalloceros Eigenmann, 1907 (Cyprinodontiformes: Poeciliidae: Poeciliinae), with the description of twenty-one new species.
