Pimpla Fabricius, 1804 (Ichneumonidae: Pimplinae) from Uruguay: a new replacement name, new records and an identification key to the species

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.</p

New records of Ticapimpla Gauld, 1991 (Hymenoptera: Ichneumonidae: Pimplinae) from Brazil and French Guiana, with taxonomic notes

Background We report the genus Ticapimpla Gauld, 1991 from French Guiana and the species Ticapimpla amazonica Palacio et al., T. carinata Palacio et al., T. matamatae Palacio et al. and T. soinii Palacio et al. from Brazilian Amazonia. The new discoveries suggest that the genus is widely distributed in Amazonian lowland rain forests. In addition, we diagnose and illustrate the males of T. carinata and T. matamatae for the first time. Short diagnoses and layer-photos for all the Amazonian species are provided.New informationThe genus Ticapimpla is reported for the first time from French Guiana and the species T. amazonica, T. carinata, T. matamatae and T. soinii from Brazilian Amazonia.

Variation in a Darwin Wasp (Hymenoptera: Ichneumonidae) Community along an Elevation Gradient in a Tropical Biodiversity Hotspot: Implications for Ecology and Conservation

Understanding how biodiversity varies from place to place is a fundamental goal of ecology and an important tool for halting biodiversity loss. Parasitic wasps (Hymenoptera) are a diverse and functionally important animal group, but spatial variation in their diversity is poorly understood. We survey a community of parasitic wasps (Ichneumonidae: Pimplinae) using Malaise traps up a mountain in the Brazilian Atlantic Rainforest, and relate the catch to biotic and abiotic habitat characteristics. We find high species richness compared with previous similar studies, with abundance, richness, and diversity peaking at low to intermediate elevation. There is a marked change in community composition with elevation. Habitat factors strongly correlated with elevation also strongly predict changes in the pimpline community, including temperature as well as the density of bamboo, lianas, epiphytes, small trees, and herbs. These results identify several possible surrogates of pimpline communities in tropical forests, which could be used as a tool in conservation. They also contribute to the growing evidence for a typical latitudinal gradient in ichneumonid species richness, and suggest that low to medium elevations in tropical regions will sometimes conserve the greatest number of species locally, but to conserve maximal biodiversity, a wider range of elevations should also be targeted

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Acrotaphus wagnerianae sp. n. closely resembles A. franklini Gauld and A. homeofranklini Pádua by having parts of the mesosoma black, but differs from both by having tarsal claw with lobe elongated longitudinally, apex of claw overtaking the posterior margin of lobe (Fig. 1D), margin of the gena weakly concave behind the eyes (Fig. 1C), hind leg orange, with distal 0.4 of femur, tibia and tarsus black (Fig. 1A), or males with hind leg orange with distal 0.8 of femur, tibia and tarsus black (Fig. 1E). In comparison, gena flat and tarsal claw with quadrangular lobe in both A. franklini and A. homeofranklini, and hind leg entirely black or black with parts of tibia brownish in A. franklini, and hind leg entirely black or with proximal half of the femur brownish in A. homeofranklini. Web modification. Although we did not observe a normal web in the field, it is known that normal webs of Wagneriana spiders are characterized by a vertical two-dimensional orb web, with several radii and sticky spirals. In addition, there is no retreat or barrier tangle in these webs (Levi 1991; Alayón 2011). However, the cocoon web built by the parasitized individual of Wagneriana sp. had no sticky spirals and contained a barrier tangle on both sides of the hub, resulting in an irregular tangle of non-sticky threads (Figs 2 A–C). We also observed that the web had a vertical hub (Fig. 2B), which does not present hub spirals, although it was possible to identify some radii converging to the web hub. Lines of cocoon webs were attached to the vegetation at several points (Fig. 2A).Published as part of Pádua, Diego G. & Kloss, Thiago G., 2020, A new species of Acrotaphus Townes (Hymenoptera: Ichneumonidae: Pimplinae) from the Brazilian Amazon, with notes on its host spider behavioral modification, pp. 161-168 in Zootaxa 4810 (1) on pages 163-165, DOI: 10.11646/zootaxa.4810.1.10, http://zenodo.org/record/393702

Chilean Darwin Wasps (Ichneumonidae): Biogeographic Relationships and Distribution Patterns

Ichneumonidae, or Chilean Darwin wasps, are an important component of South American hymenopteran diversity, but the taxonomic and distributional knowledge on this insect is still deficient. Taking advantage of recently updated taxonomic knowledge, we assessed biogeographic relationships at the genus level and biodiversity spatial patterns along the latitudinal gradient. The results show the presence of 264 species in Chile, arranged in 102 genera and 22 subfamilies. Biogeographic relationships are based on six elements (cosmopolitan (n = 50; 36%), endemic (n = 29; 21%), Neotropical (n = 22; 16%), Holarctic–Oriental (n = 19; 14%), south-temperate (n = 16; 11%) and Australasian) and composed of just three genera: Anacis, Labena, and Meringops. Species and genera show a bimodal distribution along the latitudinal gradient: around 34° and 38° S. From an ecoregional perspective, richness is concentrated in the Valdivian temperate forests, but when assessed at a 0.5 × 0.5 cell scale, several outstanding cells are in the contact zone between the temperate forests and the Chilean Matorral. On the other hand, the Atacama Desert shows little or no presence of Darwin wasps. The results agree with Charles Porter, who identified a northern province composed of Neotropical and cosmopolitan genera with their own representatives in the far north (11 genera), a distributional gap in the core of the Atacama Desert, and around 128 genera in Porter’s Neantarctic realm, covering all of Chile from 25° S to Cape Horn, including the Juan Fernandez islands. These results reinforce knowledge gaps and the need for more sampling and studies of available collections. Due to sampling gaps at this stage, identifying a continued increase or decrease in richness towards higher latitudes is not possible. More taxonomic and distributional information is also needed to assess potential threats to endemic genera and species
