Two New Species

Two new species are described in the Desmopachria convexa species group in the Neotropical genus Desmopachria Babington: D. mancosp. nov. (Guyana), and D. mortimersp. nov. (Costa Rica). Two subgroups, the D. convexa-convexa and the D. convexa-signata groups are defined. Desmopachria convexa-convexa species are from North and Central America and have a subapical articulable lobe on the male lateral lobe that is large and elongate and extends well beyond the slender, oblique apex of the lateral lobe. Desmopachria convexa-signata species are from South America and have a subapical articulable lobe on the male lateral lobe that is small and discrete and does not extend beyond the truncate apex of the lateral lobe. The male genitalia of all recognized species in the D. convexa group are redrawn from the literature. New species are illustrated from specimens and described species have morphological features redrawn from published illustrations.

Two new species of Sabethes subgenus Sabethinus (Diptera: Culicidae) from Costa Rica are formally named Sa. andreae and Sa. theresae. Descriptions consisting of differential and diagnostic morphological characters are provided for adults, male genitalia and fourth-instar larvae. The male genitalia and the fourth-instar larva and pupa of both species are illustrated. The species are compared with the four previously described species known to occur only in South America, i.e. Sa. idiogenes, Sa. intermedius, Sa. melanonymphe and Sa. xhyphydes. A new country record for Colombia is reported for Sa. xhyphydes and keys are provided to distinguish the adults and larvae of the six species.

Three New Species

The Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.

Tanytarsus is a highly diverse genus of Chironomidae (Diptera), distributed worldwide. In the Neotropics, 84 species are known, but only five have been recorded from Central America to date. In the present article, two new species of the Tanytarsus ortoni species group are described and illustrated based on male specimens collected from Costa Rica, T. braini sp. nov. and T. costarica sp. nov.

Two New Species

The Protohermes latus species group is recognized by the sexual dimorphism of the adult pronotum and the male genitalia which possess a bilobed ectoproct. Protohermes sonus sp. nov. from northwestern Myanmar and Protohermes sublunatus sp. nov. from northeastern India are herein described as new species placed in the P. latus group. The potential for peculiar behaviour during courtship of the species in the P. latus group is also discussed based on some remarkable morphological features.

A New Species

AbstractCopris incertus Say, 1835 (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini) has been described as a New World coprophagous scarab distributed from Mexico to Ecuador with large discontinuities in its range between the Yucatán province and Costa Rica. The C. incertus species complex of the Copris minutus (Drury, 1773) species group consists of C. incertus, Copris laeviceps Harold, 1869, and Copris lugubris Boheman, 1858. Based on external morphology and male genitalia, we discovered that multiple species have been classified as C. incertus. Of these species, five are new: Copris amazonicusnew species, Copris brevicornisnew species, Copris davidinew species, Copris moroninew species, and Copris susanaenew species. Herein, we revise the organisation of the C. incertus species complex and propose a new species complex, the C. laeviceps species complex, which includes: C. davidi, Copris igualensis Warner, 1990, and C. laeviceps, formerly included in the C. incertus species complex. We provide an identification key along with species distribution maps, images of habitus, and diagnostic characters.

Salamander Species

Two new species of lungless salamanders (Plethodontidae) are described from high montane habitats of the border region between Costa Rica and Panamá. Bolitoglossa pygmaea and B. robinsoni are distinguished from each other and from other salamander species in this remote area by differences in adult body size, external proportions, foot webbing, tooth counts and/or external coloration. Both new species are assigned to the B. subpalmata species group, subgenus Eladinea. The miniaturized B. pygmaea is remarkable in being extensively depigmented, yet having the peritoneum and stomach area heavily pigmented and visible through the body wall.

Two New Species

Xiphocentron is the most species-rich genus of the pantropical family Xiphocentronidae. Among its five subgenera, Antillotrichia is the most diverse and the only one to occur in South America and Antilles. In the present study, two new species of Xiphocentron (Antillotrichia) are described from southern Atlantic Forest, Brazil. Xiphocentron gwarakeraba sp. nov. is diagnosed by the very elongate inferior appendage not bearing spines and with a simple mesal sclerite; X. muelleri sp. nov. is diagnosed by the inferior appendage with its ventral margin produced posterad and distinctly truncate. New distributional records are provided for X. acqualume, X. jaguare, X. kamakan, and X. maracanan. Additional non-genital diagnostic characters are presented for X. jaguare, and intraspecific morphological variations of forewing fork II (R3 and R4) and male genitalia are described for X. maracanan.
