A new species of Foxiphalus Barnard, 1979 is described. The material examined was collected as part of the project "Avaliação da biota bentônica e planctônica da Bacia Potiguar e Ceará" (BPOT), off northeastern Brazilian continental slope on the state of Rio Grande do Norte at depths ranging from 135 to 283 meters. Foxiphalus potiguara sp. nov. is recognized among its congeners by: rostrum slightly exceeding the article 2 of antenna 1; lower lip outer lobes with strong shoulder cusps; maxilliped inner plate with two apical robust setae; gnathopod 2 carpus shortened; pereopod 5 basis tapering distally; and epimeral plate 3 posterior margin weakly crenulated. This is the first record of Foxiphalus for the Atlantic Ocean and we provide an amended diagnosis of the genus and an identification key to its world species. In addition, two new records of Phoxocephalidae are reported from northeastern Brazil: Heterophoxus shoemakeri Andrade & Senna, 2020 and Metharpinia dentiurosoma Alonso de Pina, 2003.
本文记述了巴纳德狐猴（Foxiphalus Barnard）一新种，1979年。所检查的材料是作为“Avaliação da biota bentônica e planctônic da Bacia Potiguar e Ceará”项目（BPOT）的一部分收集的，该项目位于北里奥格兰德州巴西东北部陆坡附近，深度135至283米。potiguara Foxiphalus sp.nov.在其同源物中被认为是：主席台略超过天线1的第2条；下唇外部裂片具强壮的肩尖；上颌骨的内板，有两个顶端坚固的刚毛；颚足2长果缩短；多年生植物5基部向上逐渐变细；和外板3后边缘弱细锯齿。这是Foxiphalus在大西洋的第一个记录，我们提供了该属的修正诊断和其世界物种的鉴定钥匙。此外，巴西东北部还报告了两个新的Phoxocephalidae记录：Anrade&Senna，2020和Alonso de Pina，2003。

Cuticular hydrocarbons (CHCs) of most terrestrial arthropods primarily serve as a protective barrier against desiccation and infection. Throughout evolution, these compounds have acquired another fundamental function: the exchange of signals during interactions between nestmates. However, even though cuticular hydrocarbons perform a dual function in social insects, little is known about the effect(s) of one function on the other in social insects, and no study has evaluated this relationship in social wasps. Therefore, the present study tests the hypothesis that the level of aggressiveness presented during induced encounters between nestmates of Polybia paulista who were subjected to different conditions temperature is different than between nestmates who remained under the same temperature conditions. If the hypothesis is confirmed, it is likely because the cuticle of the wasps that had been exposed to temperature variation adjusted to these conditions leading them not to recognize the cuticular chemical signature of their colony. To test this hypothesis, workers were exposed to temperature variation in a BOD chamber and then subjected to encounters with workers who were maintained at a constant temperature of 24℃. We also used control groups to evaluate the effect of isolation alone among the groups. According to our results, our hypothesis was confirmed, the level of aggressiveness presented between nestmates who were exposed to temperature variation and those who remained at 24℃ was significantly higher than the levels of aggressiveness presented between nestmates who remained isolated but under constant temperature during the same period, in some cases, it was similar to the aggressiveness presented in encounters between wasps from different colonies. During these encounters, wasps performed alarm behavior, bites, and stings not seen during encounters between wasps that remained under the same temperature, but in isolated groups. The lack of aggressive behavior under isolated conditions indicates that isolation had no effect on chemical recognition signature. These results suggest that temperature variation may have caused some change in the cues that allow recognition between nestmates. On the other hand, these results were not caused by isolation or stress generated by the study design and difference in the CHC profile of workers, as described in the literature, is consistent with our results.

Sampling gaps across the logistically challenging and extremely biodiverse Amazonia largely hamper our understanding of broad-scale amphibian and reptile diversity patterns in this ecosystem. The Juruá River basin, a southwestern tributary of the Amazon River, is one of these undersampled areas, with only punctual information documented for these vertebrates that are spatially or temporally biased. This is especially the case for the lower-middle courses of the Juruá River, which also has comparatively less protected areas than its upper course. In order to fill some biodiversity knowledge gaps associated with amphibians and reptiles in this river basin, we combined results of our field expeditions carried out in 1992, 2005-2007, and 2018 to the Reserva Extrativista (Extractive Reserve) do Baixo Juruá, a Brazilian protected area in the right bank of the lower Juruá River. Amphibians and reptiles were sampled using four complementary methods: active surveys, pitfall traps, funnel traps, and trammel nets. We identified species or updated their taxonomic status with a reanalysis of the external morphology of the preserved material in the light of novel taxonomic literature (more than 1,500 specimens) and employment of DNA barcoding analyses for some newly collected specimens with contentious taxonomic status. Our combined sampling evidenced 149 species of amphibians and reptiles occurring in this protected area (72 amphibians, 68 squamates, six chelonians, and three crocodilians). Recorded species highlight the value of the lower Juruá River region as harboring quite diverse assemblages for these vertebrates, with species typical of the western and southwestern Amazonia sub-regions. Remarkable species records are presented, as well as accounts on species with lower taxonomic resolution. Furthermore, we discuss the biogeographic affinities of recorded assemblages based on the species geographic range and preferred habitats, and the value of this protected area to preserve the regional biological diversity.

Gynandromorphs are individuals that display both male and female features throughout the body and are rarely found in nature. We document and describe two new gynandromorphs of the large carpenter bee Xylocopa (Neoxylocopa) augusti reared from a trap-nest in La Plata, Buenos Aires, Argentina. In addition, based on a literature review, we assessed the frequency of the different types of gynandromorphs, and the body part affected, among large carpenter bees. Both gynandromorphs were assigned to the mixed category, the most common category reported in the literature (22 of 25 specimens). The remaining three specimens exhibit a bilateral pattern in all tagmata. The presence of both sexes' secondary sexual characteristics occurred more frequently on the mesosoma than on the head or metasoma. Trap nests used in bee hotels promote the conservation and study of wild bees and might facilitate the discovery of rare cases of gynandromorphs that would remain unknown otherwise under normal nesting conditions in the wild.

Here we describe a new species of Biancolina from Pernambuco, Brazil, found in association with the brown algae Sargassum spp., between 0.5 and 1.0 m depth. The new species differs from its congeners mainly by the following combination of characters: antenna 1 twice the length of antenna 2, lacinia mobilis present in both mandibles, article 4 of the maxilliped bulbose; coxa 6 with anteroventral lobe well developed as in posteroventral lobe, peduncle of uropod 1 weakly setose, palm of pereopods 5-7 lacking robust seta. This is the first record of Biancolina from the southwestern Atlantic.

Zethus is the most speciose genus among vespid wasps and has become even larger after the inclusion of closely related taxa as subgenera after a morphological phylogenetic analysis. Despite being taxonomically reviewed in the past, the Neotropical diversity of the group demonstrates potential for even further growth. A new species of Zethus (Zethoides) Fox, 1899 is herein described, being the fifth one to be described in this subgenus after the great taxonomic revision of the genus in the New World.

The holotype of the Neurostigma xanthopterum New, 1980 is here illustrated based on photographs. We also describe and illustrate a previously unknown female individual that is assigned to this species. New records for five localities in the Brazilian state of Amazonas, one in the Brazilian state of Acre and another in the Brazilian state of Amapá, are presented. The mouthparts of both sexes are here describe and illustrate. Thirteen types of variation and anomalies in the fore-hindwing veins were found. We found unique patterns in the number and shape of transverse veins in the pterostigma between individuals. We also identified a large variation in the denticles present in the lacinia. Therefore, we suggest these variable characteristics (fore-hindwing veins and lacinia denticles) are not to be used for the diagnosis of species of this genus. A revised diagnosis of N. Xanthopterum is also presented.

Xanthopterum is also presented.","PeriodicalId":35345,"journal":{"name":"Papeis Avulsos de Zoologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49367898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
