The monotypic taxon Xanthotropis n. gen. is established to accommodate Haematotropis media Golovatch, Hoffman & Spelda, 2004, known only from the vicinity of Manaus, Brazil, as it is incompatible with both its originally assigned genus and Aphelidesmus Brölemann, 1898, a suggested alternative. Xanthotropis is defined primarily by minute teeth on paranota 2–4, a sublinear posterior margin of the telson, and an elongated, distally expanded/laminate acropodite. The Aphelidesmidae Brölemann, 1916, range from northeastern Mexico and Tobago to northern Brazil and southwestern Peru; a questionable more-northerly record, from Monterey, Mexico, requires verification with fresh material. One of two families of the polydesmidan superfamily Platyrhacoidea (Leptodesmidea), Aphelidesmidae comprises two subfamilies, the nominate and Amplininae Hoffman, 1954. The latter has been addressed by several authors, and we here review Aphelidesminae by providing full synonymies, a literature review, and a key to its four genera: Aphelidesmus Brölemann, 1898; Haematotropis and Ochrotropis, both by Jeekel, 2000; and Xanthotropis n. gen.

A new genus of Gyponini, Sakakibarana gen. nov., is proposed and its type species S. amazonica sp. nov. is described and illustrated based on specimens from the Amazon Rainforest of Northern Brazil (states of Amazonas and Pará) and French Guiana. The new genus can be distinguished from other members of the Gyponini by the following morphological features: robust body, short crown, crown and face transition distinct and subfoliaceous, pronotum strongly declivous, male pygofer with caudal process, and aedeagus with dorsal apodemes with a pair of processes. A discussion comparing the new genus with the related genus Tenuacia DeLong, 1977 is provided.

New Genus And Species

A new genus and species of the Eriopisella group are described from Brazilian waters. The new genus is monotypic andclosely related to the melitid genus Netamelita Barnard, 1962, but is distinguishable from the latter by the propodus ofgnathopods 1 and 2 that is wedge-shaped, subtriangular and has the palm longer than posterior margin. This is the first amphipod of the Eriopisella group reported from Brazil.

New Genus

A new genus of Acridinae, Mesophlaeoba Kumar and Usmani gen. n. based on type species Mesophlaeoba usmanii Kumar and Usmani sp. n., is described and illustrated from India. The description was based on both conventional morphological and genital characters. The new genus is closely related to Phlaeoba Stal, 1861 but differs from it in presence of filiform antennae, absence of median carinula of fastigium of vertex and rounded posterior margin of pronotum.

A new genus of family Perlodidae, Parisoperla Huo & Du, gen. nov. is described including two new species from Guizhou Province in southwestern China. Both sexes of the new genus are characterized by the posterior margin of tergum 10 with a sclerotized process. The male membranous aedeagus is covered ventrally by patches of fine spines.

A New Species

In the revision of the Ceratopogonini of the World, Wirth & Grogan (1988) placed the species of the Monohelea multilineata group in the new genus Downeshelea, which includes 33 species (Borkent, 2011), most of them known from the New World. Borkent and Spinelli (2000, 2007) listed 18 species from the Neotropical Region and Felippe-Bauer and Silva (2008) subsequently described D. oliveirai Felippe-Bauer from northern Brazil. From Mexico, only D. multilineata (Lutz) and D. panamensis (Lane & Wirth) have been reported.

Abstract A preliminary list of the picture-winged flies known from Columbia is supplemented by 15 species based predominantly on the materials from the National Museum of Natural History, Washington, D.C., USA and now contains 28 species, including Xycores igniceps gen. & sp. n. from Venezuela and Colombia. The new genus belongs to the subfamily Otitinae and is preliminarily assigned to the tribe Cephaliini by the combination of the high clypeus, strongly widened palp, setulose vein R1, and ejaculator with short sperm pump and long fan-like apodeme. It clearly differs from other members of the tribe by the combination of elongate, narrow, apically truncated flagellomere 1, robust, mainly shining thorax with pair of microtrichose vittae, well developed proepisternal, postpronotal, acrostichal, 2 pairs of dorsocentral and scutellar setae, wing with entirely setulose vein R1 abdominal tergites devoid of microtrichia, sternites and abdominal pleura narrow, male genitalia with short epandrium, numerous (7–8) prensisetae arranged into a row along posterior margin, shallow hypandrium with pair of setulose pregonites, no postgonites or epiphallus, and an almost bare phallus with a pair of long spines submedially.

A New Species

The monotypic genus Corinnella Thomas & Dominique, 2006, was described based on nymphs from French Guyana, and since the original description nothing has been added to knowledge of its systematics. The aim of the present paper is to describe a new species of the genus from Northern Brazil, to improve its diagnoses, and to report the genus for the first time from Brazil. The new species can be recognized by: labrum with discernible anteromedial emargination and process; posterior margin of terga IV with rounded spines; and tarsal claw with seven to nine denticles, with the outer and inner denticles distinctly longer than the others.
