Jamaha rugosa ( Van Duzee, 1907) , comb. nov.

( Figure 9 )

= Colpoptera rugosa Van Duzee, 1907: 36 (original description).

Amended diagnosis. Male terminalia. Pygofer in lateral view broadest subdorsally, narrowed ventrad, anterior margin concave, posterior margin bearing large rounded lobe at caudodorsal angle (apex bluntly acute) and an elongated blunt process near midlength, ventral margin nearly linear, medioventral process lacking. Gonostyli in lateral view broad, spatulate (dorsal margin straight—excepting capitulum—ventral margin weakly convex except broadly rounded along ventrocaudal margin, apex rather truncate; capitulum short, apex diagonally truncate crowned with a flanged margin. Aedeagus nearly symmetrical, weakly upcurved, with a pair of subapical ventral processes and a pair of subapical lateral processes; ventral processes closely approximated, much shorter than lateral processes, acuminately pointed (about ¼ length of aedeagus); lateral processes nearly 3/4 length of aedeagus, symmetrical, apical half forked into three elongated processes. Anal segment in lateral view elongate, downcurved at epiproct, distally greatly expanded with apex truncate cave; in dorsal view anal tube elongate, parallel-sided, bifid past paraproct; paraproct thin and elongated.

Remarks. As we had noted in an earlier manuscript ( Bahder et al. 2023), Distant (1910) considered C. rugosa and J. elevans synonyms, although this synonymy was not subsequently followed (e.g., Metcalf 1958). Colpoptera rugosa was described from a series of specimens collected from several locations in southwestern Jamaica by Van Duzee in 1906 ( Van Duzee, 1907). Van Duzee did not designate types for his described species. However, he was working on a manuscript designating types for his species when he died in 1940 ( O’Brien 1971) and many of his described species at CASC have specimens bearing lectotype labels. However, these designations had not been published, which is necessary for validity. For Colpoptera rugosa, Van Duzee had labeled a male from Kingston (California Academy of Sciences Type number 2301) as lectotype, and a female, also from Kingston, as allotype (California Academy of Sciences Type number 2301). We examined Colpoptera rugosa syntypes from Kingston and Montego Bay.

We examined the entire series of Colpoptera rugosa syntypes from the CASC collection. The series consists of 33 specimens on 23 pins (some pins included 2 or 3 specimens), including the specimens tagged as lectotype and allotype by Van Duzee (with the remainder bearing paratype labels). Some of these specimens were damaged, lacking abdomens or other parts (including evidence of dermestid damage), but many were sound. We cleared the abdomens of 11 male specimens and found that 9 of these—including Van Duzee’s lectotype —were found to be Jamaha elevans ( Fig. 8 ). Two of the specimens—both from Montego Bay ( Fig. 9 )—were Jamaha , but not J. elevans , or any other Jamaha we are aware of. Because the validity of the species Colpoptera rugosa depends on the type designation, we are designating one of these specimens we are designating as the lectotype of Colpoptera rugosa (see material examined). Because the lectotype specimen designated here has the elongate process on the lateral margin of the male pygofer, the diagnostic feature of the genus Jamaha , we refer this species to that genus as Jamaha rugosa ( Van Duzee, 1907) , new combination.

The specimens from the Colpoptera rugosa syntype series that we found to be Jamaha elevans are listed under the material examined for that species. Unfortunately, we were unable to find a convincing diagnostic feature to separate these species without recourse to male terminalia. Because of this, we are listing only the males with cleared genitalia as being definitively J. rugosa , new combination, or J. elevans . The remainder we are listing separately under Other material examined— Colpoptera rugosa syntypes of uncertain affinity”.

Jamaha rugosa and J. elevans can be distinguished from eachother by the processes of the aedeagus where J. elevans possess a pair of dorsally angled, short processes at the apex of the aedeagus on the dorsal margin with a pair of elongate, bifid processes angled cephalad, whereas J. rugosa lacks the apical processes, and instead of bifid processes, possesses a pair of elongate trifid processes. Both J. elevans and J. rugosa can also be separated from J. playa by the armature of the aedeagus. Jamaha playa has asymmetrical armature, an apical pair of processes similar to J. elevans exist but are directly curved cephalad, on the right lateral side, exists a large bifid process and on left lateral side exists a large trifid process.
