A new species ofGonatopusLjungh, 1810,G.jaliscanussp. n., from Jalisco, Mexico, is described and illustrated. In the Neotropical region,G.jaliscanusis similar toG.forestalisOlmi, 1998, but it is distinguished by the black mesosoma (except prothorax, mesoscutum, and mesoscutellum that are yellow), and the metapostnotum being granulated and not rugose; inG.forestalisthe mesosoma is completely black and the metapostnotum is granulated and strongly rugose. In the Nearctic region, the new species is morphologically similar toG.currieiKrombein, 1962, but it is distinguished by the dull and granulated metapostonotum; inG.currieithe metapostnotum is shiny and unsculptured. The new species belongs toGonatopusgroup 7. The keys to the females of the Nearctic and Neotropical species of this group are modified to include the new taxon.

A New Species

The Miltogramminae of the Neotropical Region are low in species diversity, with no endemic genera (Pape 1996). However, the actual number of Neotropical species in this subfamily is expected to be higher according to the few comprehensive taxonomic revisions (e.g., Pape 1987a, 1989).

A New Species

Agaricus is a monophyletic genus with a worldwide distribution and more than 400 described species. The genus grows on soil and can be easily recognized by the presence of an annulus on the stipe and free lamellae which become dark brown with spore maturation. Although Agaricus is easily recognized in the field because of its macroscopic characters, identification at the species level is difficult. Based on specimens collected in the states of Paraná and Santa Catarina, in the south of Brazil, we propose a new species Agaricus globocystidiatus. The new taxon is distinguished mainly by the presence of pleurocystidia, a rare morphological character in Agaricus. Molecular analyses based on nuc rITS1-5.8-ITS2 (ITS) barcode sequences show that A. globocystidiatus belongs to Agaricus subg. Minoriopsis.

A New Species

A freshwater palaemonid shrimp from the São Francisco river basin in Brazil has been found to be a new species and is herein nominated as Macrobrachium veredensis sp. nov. It is morphologically similar to M. brasiliense (Heller, 1862), which is found in many rivers of South America. However, M. veredensis sp. nov. has a smooth carapace and few spinules on the second pereopods, while M. brasiliense has the anterolateral surface of the carapace with small spinules and the palm of the second pereopods with spines, spinules and setae. Despite their similar morphology with these subtle differences, the remarkable genetic different evidenced in DNA analysis. Molecular analyses were based on 43 sequences with 528 base pairs (bp) for 16S rDNA, and 16 new sequences with 581bp, without pseudogenes, for COI mtDNA. The nucleotide divergence between M. veredensis sp. nov. and M. brasiliense (7.0–8.5% for 16S and 11.8–12.5% for COI.), the phylogenetic topology and the haplotype network configuration and it is endemism to a region of the São Francisco river basin support the recognition of a new taxon.

New Discovery

Abstract Rhabdias pocoto n. sp. is herein described from the lungs of the swamp frog Pseudopaludicola pocoto Magalhães, Loebmann, Nogueira, Kokubum, Baptista, Haddad & Garda, 2014, from the Caatinga biome in the state of Ceará, in north-eastern Brazil. The new species is characterized by a body that dilates posteriorly, six small lips (protuberances) and two rounded lateral expansions of cuticular inflation on the anterior end, each containing an amorphous gland-like structure inside and a short and conical tail. Additionally, molecular analysis and comparison of the partial mitochondrial cytochrome c oxidase I sequence of R. pocoto n. sp. revealed genetic divergence between the new species and the sequences of Rhabdias spp. previously deposited in GenBank. Phylogenetic analysis grouped the new taxon into the R. pseudosphaerocephala species complex + R. glaurungi clade. The new discovery represents the 19th species of Rhabdias spp. described in the Neotropical region, the ninth in Brazil and the first species of Rhabdias found parasitizing South American frogs of the genus Pseudopaludicola, as well as the first Caatinga biome species of Rhabdias.

A New Species

A new species of Chironomus Meigen, C. rishii (Diptera: Chironomidae: Chironominae) from Brazil, is described and figured as adults male and female, pupa and larva. Adults of C. rishii sp. n. can be recognized by the prominent scutal tubercle and the hypopygium with narrow, elongated and strongly hooked superior volsella. Pupae of this new species are indistinguishable from most of the described Neotropical species, while larvae may be separated by the mentum with deeply incised trifid median tooth and 7 pairs of lateral teeth and the absence of lateral and ventral tubules. This last feature would place C. rishii sp. n. within the 'salinarius group'. However, this is not a group in the systematic sense, but an artificial grouping equivalent to a morphotype that reflects only the tubule character state. It is suggested that the absence of tubules is an adaptation for tolerating a wide range of salinity levels, however the 'salinarius group' had been also recorded in freshwater environments. Here, larvae without abdominal tubules were found in an environment with low levels of salinity, which indicates that the tubule condition may be result of further abiotic pressures, and configures a rather enigmatic scenario to this feature, particularly when considered the fact that larvae of Chironomus having tubules had also been recorded at the same habitat, living under similar conditions of C. rishi sp. n.

AbstractNotes are given on the five species of Synergus Hartig, 1840 recorded from Central and South America, including a key for their identification. A new species, S. colombianussp. nov., is described from Colombia. The new species is an inquiline of an unidentified cynipid gall on Quercus humboldtii Bonpl. (Fagaceae). Synergus colombianus is the first Synergus species recorded from Colombia and the most southerly record of this genus in the Neotropical region. The new species is closely related to S. cultratus Ritchie et Shorthouse, 1987, S. filicornis Cameron, 1883, and S. nicaraguensis Díaz et Gallardo, 1998, but differs from these species in characters that are discussed in the text.

Anheteromeyenia Schröder, 1927 (Spongillidae) was erected to comprise species of Heteromeyenia Potts, 1881 without microscleres. Until now, only four species of Anheteromeyenia are known, three from the Neotropical Region (A. cheguevarai, A. ornata and A. vitrea) and A. argyrosperma from the Nearctic Region. In the present study, we describe a new species of Anheteromeyenia from the Neotropical Region, which differs from other congeners in having only one category of megascleres, exclusively smooth oxeas. An identification key to species of Anheteromeyenia and an emended diagnosis of the genus are provided.
