Authors: Diego G. Pádua, Daniell R. R. Fernandes, Ilari E. Sääksjärvi

Abstract: We report new faunistic records of Pimpla Fabricius, 1804 from Uruguay. The following species are reported from the country for the first time: P. albomarginata Cameron, 1846, P. caerulea Brullé, 1846, P. perssoni Gauld, 1991, and P. semirufa Brullé, 1846. In addition, we propose a replacement name for Pimpla rufipes Brullé, 1846 and provide diagnosis, digital images, and an identification key for all the Pimpla species known to occur in Uruguay.

The mammalian faunas endemic to the Cerrado and the Caatinga https://zookeys.pensoft.net/article/10827/ ZooKeys 644: 105-157

DOI: 10.3897/zookeys.644.10827

Authors: Eliécer E. Gutiérrez, Jader Marinho-Filho

Abstract: We undertook a comprehensive, critical review of literature concerning the distribution, conservation status, and taxonomy of species of mammals endemic to the Cerrado and the Caatinga, the two largest biomes of the South American Dry-Diagonal. We present species accounts and lists of species, which we built with criteria that, in our opinion, yielded results with increased scientific rigor relative to previously published lists – e.g., excluding nominal taxa whose statuses as species have been claimed only on the basis of unpublished data, incomplete taxonomic work, or weak evidence. For various taxa, we provided arguments regarding species distributions, conservation and taxonomic statuses previously lacking in the literature. Two major findings are worth highlighting. First, we unveil the existence of a group of species endemic to both the Cerrado and the Caatinga (i.e., present in both biomes and absent in all other biomes). From the biogeographic point of view, this group, herein referred to as Caatinga-Cerrado endemics, deserves attention as a unit – just as in case of the Caatinga-only and the Cerrado-only endemics. We present preliminary hypotheses on the origin of these three endemic faunas (Cerrado-only, Caatinga-only, and Caatinga-Cerrado endemics). Secondly, we discovered that a substantial portion of the endemic mammalian faunas of the Caatinga and the Cerrado faces risks of extinction that are unrecognized in the highly influential Red List of Threatened Species published by the International Union for Conservation of Nature (IUCN). “Data deficient” is a category that misrepresents the real risks of extinction of these species considering that (a) some of these species are known only from a handful of specimens collected in a single or a few localities long ago; (b) the Cerrado and the Caatinga have been sufficiently sampled to guarantee collection of additional specimens of these species if they were abundant; (c) natural habitats of the Cerrado and the Caatinga have been substantially altered or lost in recent decades. Failures either in the design of the IUCN criteria or in their application to assign categories of extinction risks represent an additional important threat to these endemic faunas because their real risks of extinctions become hidden. It is imperative to correct this situation, particularly considering that these species are associated to habitats that are experiencing fast transformation into areas for agriculture, at an unbearable cost for biodiversity.

Identification guide to some Diaptomid species (Crustacea, Copepoda, Calanoida, Diaptomidae) of “de la Plata” River Basin (South America) https://zookeys.pensoft.net/article/5133/ ZooKeys 497: 1-111

DOI: 10.3897/zookeys.497.8091

Authors: Gilmar Perbiche-Neves, Geoffrey Allan Boxshall, Daniel Previattelli, Marcos Gomes Nogueira, Carlos Eduardo Falavigna Da Rocha

Abstract: An identification guide is presented for species of calanoid copepod family Diaptomidae from “de la Plata” River Basin (Argentina, Brazil, Bolivia, Paraguay and Uruguay). It was based on material collected during the summer and winter of 2010 from 43 sites across the eastern part and the lower stretches of this basin, the second largest in South America and the fourth in the world. The guide contains identification keys and species diagnoses for males and females, richly supported by scanning electronic micrographs and/or line drawings of 19 species. It also includes some general remarks on the taxonomy and phylogenetic relationships of these species. The key was adjusted to be useful for these species only, with separate keys for each sex, and is the first for females of South America. One species classified herein as incertae sedis was not included in the analysis. At least ten other species have previously been recorded in the basin but were not present in our samples. This is the first attempt to compile comprehensive taxonomic information on this group of copepods in this region, and it is expected to become a useful tool for biologists and young taxonomists interested in the crustacean biota of the Neotropical region.

An illustrated key to Neotropical species of the genus Meteorus Haliday (Hymenoptera, Braconidae, Euphorinae) https://zookeys.pensoft.net/article/4942/ ZooKeys 489: 33-94

DOI: 10.3897/zookeys.489.9258

Authors: Helmuth Aguirre, Luis Felipe Ventura de Almeida, Scott Richard Shaw, Carlos Eduardo Sarmiento Monroy

Abstract: A comprehensive key for 75 species of Meteorus distributed across 15 Neotropical countries is presented. Eleven new species from Bolivia, Costa Rica and Ecuador are described: M. albistigma, M. carolae, M. eurysaccavorus, M. fallacavus, M. flavistigma, M. haimowitzi, M. magnoculus, M. martinezi, M. microcavus, M. noctuivorus and M. orion. Expanded range distributions are recorded for M. andreae, M. farallonensis, M. guineverae, M. jerodi, M. kraussi, M. papiliovorus and M. quimbayensis. The host of M. jerodi is reported for the first time: a noctuid larva feeding on Asteraceae. Meteorus papiliovorus is recorded attacking Papilionidae larvae in Ecuador, therefore displaying a similar host family preference as formerly documented from Costa Rica and Colombia.

Two new species of Chaco Tullgren from the Atlantic coast of Uruguay (Araneae, Mygalomorphae, Nemesiidae) https://zookeys.pensoft.net/article/3249/ ZooKeys 337: 73-87

DOI: 10.3897/zookeys.337.5779

Authors: Laura Montes de Oca, Fernando Perez-Miles

Abstract: We describe two new species of the nemesiid spider genus Chaco from Rocha Province, Uruguay. These new species are diagnosed based on genital morphology, male tibial apophysis spination, and burrow entrance. We test cospecificity of one species, C. costai, via laboratory mating experiments. The new species are diagnosed and illustrated and habitat characteristics, and capture behavior are described. We conduct a cladistic analysis based on a previously published morphological character matrix that now includes the newly described species.

The species of the genus Hypodynerus de Saussure (Hymenoptera, Vespidae, Eumeninae) occurring in Brazil https://zookeys.pensoft.net/article/3079/ ZooKeys 296: 25-33

DOI: 10.3897/zookeys.296.4794

Authors: Bolívar Garcete-Barrett, Marcel Hermes

Abstract: An identification table and descriptions are given to recognize the two species of Hypodynerus (Hymenoptera: Vespidae: Eumeninae) recorded from Brazil: H. arechavaletae (Brèthes) and H. duckei (Bertoni) comb. n. The lectotype is designated and the male is described for Hypodynerus duckei, its presence being recorded from Brazil for the first time.

Revision of the Neotropical caddisfly genus Itauara Müller, 1888 (Trichoptera, Glossosomatidae) https://zookeys.pensoft.net/article/2589/ ZooKeys 114: 41-100

DOI: 10.3897/zookeys.114.1405

Authors: Desiree Robertson, Ralph Holzenthal

Abstract: Systematics of the genus Itauara Müller, 1888 are reviewed. A generic diagnosis, illustrations, and descriptions are provided for males. The genus can be identified by several features of the male genitalia including an extremely reduced phallobase and a phallic apparatus that consists of a sclerotized dorsal sheath covering a very membranous ventral portion. A total 18 species are described as new: Itauara alexanderi, new species (Brazil), I. bidentata, sp. n. (Guyana), I. blahniki, sp. n. (Brazil), I. charlotta, sp. n. (Brazil), I. emilia, sp. n. (Brazil), I. flinti, sp. n. (Brazil), I. guyanensis, sp. n. (Guyana), I. jamesii, sp. n. (Brazil), I. julia, sp. n. (Brazil), I. lucinda, sp. n. (Brazil), I. ovis, sp. n. (Guyana, Venezuela), I. peruensis, sp. n. (Peru), I. rodmani, sp. n. (Brazil), I. simplex, sp. n. (Brazil), I. spiralis, sp. n. (Guyana), I. stella, sp. n. (Brazil), I. tusci, sp. n. (Brazil), and I. unidentata, sp. n. (Guyana). These additions bring the total fauna of Itauara to 22 species.
