E24687B4FFA9FFE6848F5A5BFAF3F901.taxon	materials_examined	Type specimen. Ψ holotype (NMNH) taken by C. Beutelspacher, 22 October 1968, 6 km (3.8 mi) from Bochil, Chiapas, Mexico. This village is approximately 40 km (25 mi) NE San Cristobal las Casas, but its direction from Bochil is unknown. Habitat. The holotype was encountered in Vriesia chiapensis Matuda (Loomis 1971). Remarks. The specific identity of lateralis, the youngest name in the genus, cannot be determined until a reasonably topotypical adult male is collected. I provide an illustration of the cyphopods (Fig. 3).	en	Shelley, Rowland M.

According to Moritz & Fischer (1975: 235), there are 3 ɗ and 7 Ψ syntypes, but I only received one male, and the remaining individuals (I counted 19 heads) appear to be immatures; the other males must be lost as are the gonopods of the existing male. Pleurotergites 3 – 38 of this male are on insect pins, but the anterior and caudal ends are missing; the gonopodal aperture is clearly visible, but the gonopods have been removed and were not in the vial.	en	Shelley, Rowland M.

E24687B4FFA9FFE7848F5841FE86F90F.taxon	discussion	Remarks. As noted by Hoffman (1999), Mauriès (1972) did not detect a seminal canal in the types of P. olmecus and concluded that there was none in Parajulus. I too did not find one, but I was unable to fully clear the pgs; perhaps Mauriès did not clear the posterior gonopod or do so for a long enough time. The type specimens have fibrils that project varying distances beyond the short, anterior branch, and I dissected a second male to confirm this. Fibrils occur only within the seminal canal, so their presence in P. o l m e c u s is prima facie evidence of such; perhaps it is short and difficult to observe, particularly in a gonopod that has been incompletely cleared. No other nominal species even vaguely resembles P. olmecus, so Parajulus must presently be regarded as a monotypic genus.	en	Shelley, Rowland M.

E24687B4FFAAFFE5848F5D39FC0AFBD7.taxon	discussion	Remarks. Loomis (1968 a) placed Mexicoiulus in synonymy under Parajulus on the advice of N. B. Causey, and Hoffman (1980) maintained this status. However, Hoffman (1999) resurrected the taxon and stated that prior synonymies were incorrect; I concur with this action. Based on similarities to aspects of Verhoeff's illustrations (1926: 70, figs. 9 – 10), I tentatively group " P. " stylifer, " P. " r. rosanus Chamberlin, 1943, and " P. " rosanus gyratus Loomis, 1971, with M. dampfi, but I retain them in " Parajulus " and do not formalize combination with Mexicoiulus.	en	Shelley, Rowland M.

E24687B4FFAAFFE3848F5993FC84FD21.taxon	discussion	Remarks. The irregular ventromedial margin of the pg of the ɗ syntype, which does not exhibit spinules, suggests that one or more structures in this position have been broken off and removed. An undamaged male topotype is necessary to show the ags, clarify the condition of the pg, and establish the true identity of stylifer. The only locality provided in Pocock's (1907) original description was Guatemala without further details; those above are on vial labels. The name, stylifer, should be assigned to a topotypical male from Volcan de Agua that matches the seemingly fragmented posterior gonopod in fig. 13; it should not be applied to a male from Volcan de Acatenango, which may be a different species. The syntype localities of " P. " stylifer are ca. 1,072 km (670 mi) south of the type locality of M. dampfi. Thus, congeneric status seems implausible, but the resemblance of the apparently broken pg of stylifer and Verhoeff's illustration of dampfi (1926: 70, fig. 9) is undeniable.	en	Shelley, Rowland M.

E24687B4FFACFFE0848F5DA1FE02FDA9.taxon	discussion	Remarks. The pg of " P. " rosanus is so simple as to enable a complete diagnosis. All three branches vary within this pattern, and as specific names are available for the two variants, I conserve them at the subspecific level. The configuration of the pg caudal projection in rosanus appears different than that depicted by Verhoeff (1926: 70, fig. 9), which seems shorter, narrower, and more sharply bent. Consequently, " P. " rosanus may not belong with M. dampfi, but I tentatively place it here because of the similarly falcate solenomere that is clearly evident in Verhoeff's drawings. A valid question arises as to distinguishing specific and subspecific differences when little material is available and further sampling is not feasible in the short-term. An element of subjectivity is inevitable, and my interpretation is based on both anatomy and geography, though some workers deplore employing the latter in even preliminary taxonomic decisions. The level of differentiation between rosanus / gyratus, and subsequently herein pueblanus / zempoalus and schmidti / australis n. subsp., involves the degree of expression of common traits like the breadth of the solenomere and the distal curvature of the caudal projection, rather than the presence of totally different features. While documentation of anatomically intermediate forms, constituting irrefutable proof of intergradation, is desirable and clearly the best evidence of geographic races, such forms are not known to exist for these taxa, and it is not presently possible to travel to Mexico and Guatemala to search for them. Decisions must therefore be based on the available material, and without additional evidence, I interpret the former situation as reflecting subspecies and the latter as evidence of reproductive isolation and hence full species. From my overall experience with millipeds in general and parajulids specifically, I believe that rosanus / gyratus and the other forms mentioned above are not reproductively isolated from each other; they are geographically compatible, and their gonopodal configurations seem too similar to represent distinct species. It is also appropriate to recognize australis taxonomically because it constitutes the southernmost record of the family and order in the hemisphere, and as names are available for the other forms, it is likewise appropriate to conserve them at the subspecific level. Valid argumentations can be advanced for different interpretations, but when field sampling is feasible, I have found that anatomically intermediate forms can be retrieved between ones that are as proximate and similar as these are. In documented cases of subspecies linked by intergrades, they likewise differ by the degree of expression of common features; for example in Sigmoria (Sigmoria) latior (Brölemann, 1900) (Polydesmida: Xystodesmidae) (Shelley 1976, 1981; Shelley & Whitehead 1986), the subspecies differ in the degree of expansion of the medial gonopodal flange, the size and shape of the prefemoral process, the size of the telopodal tooth, and the length of the distal zone. In my experience, when geographically proximate surface-dwelling forms differ in this manner, they probably represent a clinal continuum and hence are more likely to be subspecies than species. I adhere to this observation herein, but as with any taxonomic action, alterations can be effected if future discoveries so dictate. An additional benefit in this particular case is that two available names can be conserved while simultaneously simplifying the nomenclature.	en	Shelley, Rowland M.

E24687B4FFB3FFFC848F5CE4FACEF9E4.taxon	discussion	Remarks. The identity of phenotypus is critical to determining the status of Pheniulus, and an adult male topotype is needed. Even though the pgs differ substantially from those in Chamberlin's drawings (1943: 83, figs. 60 – 61) of phenotypus, I suspect that pueblanus may be congeneric because of concordance in the configurations of the ag coxal processes. However, absent more data, I do not make the formal assignment.	en	Shelley, Rowland M.

E24687B4FFB9FFF5848F5E99FB23F95F.taxon	discussion	Remarks. I suspect that this sample, which represents a new country and the southernmost record of both the family and order in the New World, is near the southern limit for both taxa. They certainly do not range southward to Panama, because Loomis and others would surely have discovered parajulids there, nor are they likely to occupy Costa Rica, where numerous arthropodologists have sampled the terrestrial fauna without encountering them. A plausible southern limit is the 40 km (25 mi) wide Gulf of Fonseca at the southern end of El Salvador and ca. 200 km (125 mi) south of Cerro Verde, which separates the country from Nicaragua. Occurrence also is plausible in southern Honduras, only 64 km (40 mi) north of Cerro Verde.	en	Shelley, Rowland M.
