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.

The genera Abaria Mosely 1948 and Drepanocentron Schmid 1982 are recorded in China for the first time. In this study, two new species, Abaria herringbona sp. nov., from Guang-xi, and Drepanocentron fuxiensis sp. nov., from An-hui, are described and illustrated. Male genitalia of these two new species is distinguishable from those of other Abaria and Drepanocentron species. In addition, Melanotrichia attia Malicky & Chantaramongkol 1992 is a new record for the Chinese caddisfly fauna.

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.

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.

New Diagnosis

Two new species of Oecobiidae are described from Central and South America, representing the first native members of the family recorded south of Mexico. Oecobius eberhardi sp.nov. is described based on male and female specimens collected from two localities in Costa Rica. Platoecobius kooch sp.nov., the second species in the genus, is described from female specimens collected in Southern Argentina. A new diagnosis is proposed for the genus Platoecobius Chamberlin & Ivie, 1935, which now includes one species endemic to the south-eastern USA and another from Argentinean Patagonia.

Two New Species

Two new species of the Plecoptera family Diamphipnoidae are described from Chile. Illustrations of the details of the male genitalia, female genitalia, and eggs are provided for these two new taxa. Diamphipnoa fresiae sp. nov. has the lowest latitudinal distribution of the genus in South America and the male is the smallest known for the family and has also unusual wing venation. Diamphipnopsis oncolensis sp. nov., also a small species is known only from the Parque Oncol, south of Valdivia, Chile. This species is characterized by its distinctive abdominal coloration pattern in both sexes of the adult. Additionally, the large diameter of the eggs and the prominent tubercles of the chorion characterize this new species.

First Time

Records of 48 species belonging to the order Arthoniales from Bolivia are presented. Cryptothecia rosae-iselae Flakus & Kukwa and Lecanactis minuta Ertz, Flakus & Kukwa are described as new to science. Thirty-seven species are reported for the first time from Bolivia, seven of which, Alyxoria apomelaena, Cryptothecia darwiniana, C. groenhartii, C. megalocarpa, Herpothallon furfuraceum, Lecanographa uniseptata, and Opegrapha subvulgata, are new to South America. This raises the number of Arthoniales known from the country up to 72. Two new combinations are proposed: Alyxoria apomelaena (A. Massal.) Ertz for Opegrapha apomelaena A. Massal. and Myriostigma napoense (Kalb & Jonitz) Kukwa for Cryptothecia napoensis Kalb & Jonitz. Cresponea melanocheiloides is the second species of the genus shown to contain a xantholepinone. Cresponea melanocheiloides is reported as new to Costa Rica and Panama, Cryptothecia megalocarpa as new to the Netherlands Antilles and Guyana and C. striata is new to Colombia, Costa Rica, French Guiana and the Netherlands Antilles. Distribution data are reported for each species, with taxonomic remarks provided for new and some problematic taxa.
