A new species of epigean ricinuleid of the genus Pseudocellus Platnick, 1980 from El Triunfo Biosphere Reserve, Chiapas, Mexico is described. DNA barcoding utilizing mitochondrial cytochrome c oxidase subunit 1 (CO1) and morphology were used for species delimitation. Molecular analyses and species delimitation included four methods: 1) General Mixed Yule Coalescent model (GMYC), 2) Automatic Barcode Gap Discovery (ABGD), 3) Bayesian Poisson Tree Process (bPTP), and 4) Assemble Species by Automatic Partitioning (ASAP). All molecular methods and morphology were consistent in delimiting and recognizing the new species described herein. The average interspecific genetic distance (p-distance) among analyzed species of Pseudocellus was 11.6%. The species is described based on adult males and females: Pseudocellus giribeti sp. nov. This is the seventh species described from Chiapas, which holds the highest number of ricinuleids species for the country. The total number of described species of Pseudocellus from Mexico increases to 21, having the highest species diversity of known ricinuleids worldwide.

The spider genus Ixchela Huber 2000, is comprised of 22 species distributed from north-eastern Mexico to Central America, including the two new species described herein from Mexico: Ixchela panchovillai sp. nov. and Ixchela zapatai sp. nov., both from the state of Oaxaca and described for both sexes. DNA barcoding utilizing mitochondrial cytochrome c oxidase subunit 1 (COI) and morphology were used for species delimitation. Molecular analyses and species delimitation included four methods: 1) corrected p-distances under neighbor-joining (NJ), 2) general mixed yule coalescent model (GMYC), 3) automatic barcode gap discovery (ABGD), and 4) Poisson tree processes (bPTP). All molecular methods and morphology were consistent in delimiting and recognizing the two new species describing herein. The average inter-specific genetic distance (p-distance) within the genus Ixchela is 12%. Ixchela panchovillai sp. nov. is closely related in the NJ analysis with I. placida, with an average p-distance of 7.9%, whereas I. zapatai sp. nov. is closely related to I. taxco, with an average p-distance of 8.4% between both species. Additionally, identification keys for males and females of the genus Ixchela are presented.

A new species of Elachistocleis (E. magnus) is described from the Amazon basin, in the municipality of Espigão do Oeste, state of Rondônia, Brazil. It differs from all other species of the genus by the combination of the following characters: i) size larger than 31 mm in adult males, ii) grayish ventral coloration, iii) presence of large post-commissural glands, iv) lack of red coloration in the body, and v) grayish dorsum in preserved individuals. There is dimorphism between males and females in size, structures and coloration. Vocalizations and larvae remain unknown.

A New Species

A new species of the spider genusLoxoscelesHeineken & Lowe, 1832,Loxoscelesmalintzisp. n., is described from the states of Puebla, Morelos and Guerrero, in the central region of Mexico. The description is based on adult males and females with morphological and ultra-morphological images. Updated distribution maps are provided for the 39 species recorded from the Mexican territory (including the new species). The states with the greatest diversity are Baja California Sur, Baja California and Sonora, with five species each. A total of 441 records for the 39 species, based on arachnological collections, data bases and literature, were used to update the distribution maps.LoxoscelesbonetiGertsch, 1958 is the species with the highest number of records in Mexico, with a total of 58 records from different localities. The states with the most records so far are Guerrero, with 55 records, Morelos, with 35 records, and Baja California Sur, with 30 records.Loxoscelesrufescens(Dufour, 1820), an introduced species, is recorded for the second time in Mexico, from the state of Chihuahua, being the first well-documented record for the country. Mexico has the greatest diversity of species ofLoxoscelesworldwide, with 39 (two introduced species) of the 134 described species. Additionally, biogeographical comments for the species from Mexico are provided.

Macrostemum is the second largest genus of Macronematinae with about 104 described species distributed in the Neotropical (18), Afrotropical (20), Australasian (7), Palearctic (2), Nearctic (3) and Oriental (54) regions. Despite its great diversity, knowledge about its immature stages is scarce: worldwide, only 7 species (6.7%) have larvae and/or pupae described. From the Neotropics, only one species, Macrostemum ulmeri (Banks, 1913), has described larvae and pupae. The objectives of this study are to describe and illustrate a new species, Macrostemum araca sp. nov., based on adult males and females from Serra do Aracá, Amazonas, Brazil, and the larvae and pupae of M. brasiliense (Fischer, 1970) from an Atlantic Forest fragment in São Paulo state using the metamorphotype method. In addition, this species is recorded for the first time for Minas Gerais state.

Thirty-nine species of Sarcophaginae are recorded from Buenos Aires Province (Argentina). A new species, Microcerella asymmetrica sp. nov., is described. Females of Oxysarcodexia bicolor Lopes, O. marina Hall, and Sarcophaga (Lipoptilocnema) koehleri Blanchard are described for the first time. Four nomenclatorial actions are reported: Sarcohelicobia elegans Blanchard is established as a new junior synonym of Nephochaetopteryx cyaneiventris Lopes, and lectotypes are designated for Oxysarcodexia delpontei Blanchard [a junior synonym of Oxysarcodexia paulistanensis (Mattos)], Sarcophaga argentina Brèthes [a junior synonym of Sarcophaga (Liopygia) argyrostoma (Robineau-Desvoidy)], and Neobellieria brethesi Blanchard [a junior synonym of Sarcophaga (Neobellieria) polistensis Hall]. Blaesoxipha (Tephromyia) hospes (Aldrich), Peckia (Euboettcheria) florencioi (Prado & Fonseca), Ravinia advena (Walker), R. aureopyga (Hall) and Sarcodexia lambens (Wiedemann) are newly recorded from Buenos Aires Province, and Udamopyga percita is newly recorded from Argentina. A key is presented to the adult males and females of 36 of the 39 species of Sarcophaginae recorded from Buenos Aires province. Notes on distribution, biology, life history and host records are also given.

Gyrinus rhyssonotum sp. n. is described and illustrated based on adult males and females collected in Barcelos County, Amazonas state, Brazil. The new species belongs to the subgenus Oreogyrinus Ochs, 1935 and it is compared with Gyrinus (Oreogyrinus) fittkaui Ochs, 1963 and G. (O.) opalinus Régimbart, 1883, both occurring in the Brazilian Amazonas and G. (O.) colombicus Régimbart, 1883 and G. (O.) venezolensis Ochs, 1954, these two latter alien to the Brazilian fauna but with which G. (O) rhyssonotum sp. n. seems to be more closely related, though the new species can be distinguished from both by a series of characteristics, mainly observed in the body shape, elytra, pronotum, and in male and female genitalia.

A new species of predaceous midge, Austrosphaeromias setosa sp. nov., is described and illustrated from adult males and females collected in the Patagonian-Andean region of Argentina and Chile. Based on examination of the type species of Austrosphaeromias Spinelli, 1997 and recently collected specimens from near the type-locality, the female and previously unknown male of Austrosphaeromias chilensis (Ingram & Macfie, 1931) are also described and illustrated. Descriptions are accompanied by color photographs and illustrations of key features of females and males of both species. We also provide a key to adult females and males of the four species of Austrosphaeromias.
