Abstract: Recent field surveys in the eastern Canary Islands (Spain), followed by contributions of new occurrence records through the citizen science platform iNaturalist.com and the social media photo repository Flickr.com have revealed the presence of an overlooked small carder bee species (genus Pseudoanthidium Friese (Megachilidae: Anthidiini)) on the islands of Lanzarote and Fuerteventura. Here, we combined morphology, DNA barcodes (mitochondrial cytochrome c oxidase subunit I, COI) and ecological data (distribution, altitudinal ranges and environmental niche classification) to describe this species as Pseudoanthidium (Pseudoanthidium) jacobii sp. nov. We provide an illustrated description along with diagnostic morphological characters to separate it from P. (P.) canariense (Mavromoustakis, 1954), the only other congeneric species known from the neighbouring islands of La Gomera, Tenerife and Gran Canaria and from which it is separated by a genetic distance of 2.7%. We also evaluated the extent of shared environmental niche space among the two Pseudoanthidium species, and our results show a significant difference in elevation range as well as a very small (less than 1%) overlap between the modelled climatic niche of P. jacobii and that of P. canariense. Given the extremely restricted geographic distribution and the fragile and isolated nature of the habitat and host plants of this new island endemic species, we assign it an IUCN conservation status of “EN” (endangered) and discuss avenues for future research on the ecology and conservation of wild bees in the Canary Islands and neighbouring regions.

Additions to the xiphydriid woodwasp (Hymenoptera, Xiphydriidae) fauna of New Caledonia https://jhr.pensoft.net/article/21787/ Journal of Hymenoptera Research 61: 65-74

DOI: 10.3897/jhr.61.21787

Authors: David R. Smith, Claire Villemant

Abstract: Calexiphyda marystellae Villemant & Smith, sp. n., is described from New Caledonia. This is the sixth species of Xiphydriidae known from New Caledonia. A key to the six species is given, the female of C. crocea Smith is described, and a new locality for this species and for C. caledonia Smith is given.

Discovery of Trichopria keralensis (Hymenoptera, Diaprioidea, Diapriidae) in South Korea and Japan, a review of the keralensis species group of Trichopria and the nomenclature and synonymy of Alareka https://jhr.pensoft.net/article/8546/ Journal of Hymenoptera Research 52: 143-151

DOI: 10.3897/jhr.52.8546

Authors: Chang-Jun Kim, David Notton, Jong-Wook Lee

Abstract: Trichopria keralensis is recorded for the first time from South Korea and Japan and a detailed redescription and photographs of this species are given. The genus Alareka is a junior synonym of Trichopria syn. n. Alareka keralensis is transferred to Trichopria keralensis comb. n. T. keralensis and closely related species are referred to the keralensis species group of Trichopria. The keralensis species group is recorded here for the first time from the East Palaearctic, West Palaearctic, Afrotropical and Australian (Oceanian) regions. The multiple original spellings of Alareka, Alarika, Alareka keralensis and Alareka keralaensis are resolved.

A rare ant on Samoa: first record of the cryptic subfamily Proceratiinae (Hymenoptera, Formicidae) and description of a new Proceratium Roger species https://jhr.pensoft.net/article/5849/ Journal of Hymenoptera Research 46: 35-44

DOI: 10.3897/JHR.46.5849

Authors: Cong Liu, Georg Fischer, Evan Economo

Abstract: In this study we present a taxonomic update for the Oceanian Proceratium. A recent ant biodiversity survey in Samoa collected an unknown Proceratium species, which we describe here as Proceratium silisili sp. n. This new species also presents the first record of this genus, as well as the whole subfamily Proceratiinae, in Samoa. Proceratium silisili is clearly distinguishable from the other Oceanian Proceratium species based on the differences in petiole node shape, number of mandible teeth, shape of the abdominal segment IV, as well as the surface sculpture on the head. A detailed description of P. silisili, high-quality specimen images, as well as an identification key to Oceanian species and a diagnostic discussion are provided.
