The rarely encountered spider genusHexurellaGertsch & Platnick, 1979 includes some of the smallest mygalomorph spiders in the world, with four poorly known taxa from central and southeastern montane Arizona, southern California, and northern Baja California Norte. At time of description the genus was known from fewer than 20 individuals, with sparse natural history information suggesting a vagrant, web-building, litter-dwelling natural history. Here the first published taxonomic and natural history information for this taxon is provided in more than 50 years, working from extensive new geographic sampling, consideration of male and female morphology, and sequence capture-based nuclear phylogenomics and mitogenomics. Several new species are easily diagnosed based on distinctive male morphologies, while a complex of populations from central and northern Arizona required an integrative combination of genomic algorithmic species delimitation analyses and morphological study. Four new species are described, includingH. ephedrasp. nov.,H. uwiiltilsp. nov.,H. xericasp. nov., andH. zassp. nov.Females ofH. encinaGertsch & Platnick, 1979 are also described for the first time. It is predicted that additional new species will ultimately be found in the mountains of central and northwestern Arizona, northern mainland Mexico, and the Mojave Desert of California.

An illustrated key to Anthophoroides Cockerell & Cockerell, with the description of three new species (Hymenoptera: Apidae)
Three new species of the cosmopolitan bee genusAnthophoraLatreille are described and figured from North America, all of the subgenusAnthophoroidesCockerell & Cockerell and all based on a series of females and males.Anthophora(Anthophoroides)buchmannisp. n. from Arizona, USA and Sonora, Mexico;A. (A.)cinerulasp. n. from California, Nevada, Utah, and Arizona, USA; whileA. (A.)kellieaesp. n. is recorded from southern California and Arizona, USA and Baja California, Mexico. An illustrated key is presented to the species ofAnthophoroides.

Integrative taxonomic practices that combine multiple lines of evidence for species delimitation greatly improve our understanding of intra- and inter-species variation and biodiversity. However, extended phenotypes remain underutilized despite their potential as a species-specific set of extracorporeal morphological and life history traits. Primarily relying on variations in wing patterns has caused taxonomic confusion in the genusAciurina, which are gall-inducing flies on Asteraceae plants in western North America. However, species display distinct gall morphologies that can be crucial for species identification. Here we investigate a unique gall morphotype in New Mexico and Colorado that was previously described as a variant of that induced byAciurina bigeloviae(Cockerell, 1890). Our analysis has discovered several consistent features that distinguish it from galls ofA. bigeloviae. A comprehensive description ofAciurina luminariaBaine,sp. nov.and its gall is provided through integrative taxonomic study of gall morphology, host plant ecology, wing morphometrics, and reduced-representation genome sequencing.more » « less

Abstract The salamander,Ambystoma annulatum, is considered a “species of special concern” in the state of Arkansas, USA, due to its limited geographic range, specialized habitat requirements and low population size. Although metazoan parasites have been documented in this salamander species, neither its native protists nor microbiome have yet been evaluated. This is likely due to the elusive nature and under‐sampling of the animal. Here, we initiate the cataloguing of microbial associates with the identification of a new heterlobosean species,Naegleria lustrarean. sp. (Excavata, Discoba, Heterolobosea), isolated from feces of an adultA. annulatum.more » « less

Hesionidae Grube, 1850 currently comprises over 175 species in 28 genera, placed in several subfamilies. Discoveries in recent years have largely been of deep-sea taxa. Here we describe a further four new hesionid species, mainly from methane ‘cold’ seeps at around 1000–1800 m depths off the Pacific coast of Costa Rica and new record of another species. Several of these taxa also occur at methane seeps in the Guaymas Basis (Mexico) and off the USA west coast (California and Oregon). The phylogenetic relationships within Hesionidae are reassessed via maximum parsimony and maximum likelihood analyses of DNA sequences from nuclear (18S rRNA and 28SrRNA) and mitochondrial (16SrRNA and Cytochrome c oxidase I) loci for the new samples. On the basis of these results, we refer one of the new species to Gyptis Marion & Bobretzky in Marion, 1874, one to Neogyptis Pleijel, Rouse, Sundkvist & Nygren, 2012, and two to Sirsoe Pleijel, 1998. The new species Gyptis robertscrippsi n. sp., Neogyptis jeffruoccoi n. sp., Sirsoe dalailamai n. sp. and Sirsoe munki n. sp. We refer to a collection of individuals from seeps ranging from Oregon to Costa Rica as Amphiduropsis cf. axialensis (Blake & Hilbig, 1990), even though this species was described from hydrothermal vents off Oregon. Neogyptis jeffruoccoi n. sp. was generally found living inside the solemyid clam Acharax johnsoni (Dall, 1891). The position of Hesiolyra bergi Blake, 1985 is resolved on the basis of newly-collected specimens from near the type locality and, as a result, Hesiolyrinae Pleijel, 1998 is synonymized with Gyptini Pleijel, 1998 (and Gyptinae Pleijel, 1998).http://zoobank.org/urn:lsid:zoobank.org:pub:9C0E88EE-34F8-4F25-9EC8-91797618AC86more » « less
