  • The North American bees of the genus Ptilothrix Cresson, 1878 (Hymenoptera, Apidae, Emphorini), with the description of two new species
Title: The North American bees of the genus Ptilothrix Cresson, 1878 (Hymenoptera, Apidae, Emphorini), with the description of two new species
Ptilothrix Cresson is a genus of New World bees with an amphitropical distribution. Like other genera in the tribe Emphorini, Ptilothrix have narrow pollen preferences. These solitary ground-nesting bees exhibit a remarkable nesting behavior in which females carry water from ponds to facilitate the excavation of the hard soil where they nest. With 16 described species, there are few taxonomic studies and, before this work, a lack of taxonomic treatments for the species in North America. Thus, in this study we revised and recognized four species for the region: Ptilothrix bombiformis Cresson, Ptilothrix sumichrasti Cresson, Ptilothrix chiricahua Florez-Gomez & Danforth, sp. nov. and Ptilothrix zacateca Florez-Gomez & Danforth, sp. nov. We describe and illustrate males and females of the two new species. We also present diagnoses for the four species, a key to identify them, and a map of their geographic distributions.  more » « less

    We describe new species in the genus Ceroptres Hartig, 1840 (Hymenoptera: Cynipidae: Ceroptresini) represented by voucher material sequenced by Ward et al. (2024). We describe 22 new species, all authored by Nastasi, Smith, & Davis: C. anansii sp. nov., C. anzui sp. nov., C. bruti sp. nov., C. curupira sp. nov., C. daleki sp. nov., C. dandoi sp. nov., C. demerzelae sp. nov., C. iktomii sp. nov., C. jabbai sp. nov., C. jarethi sp. nov., C. lokii sp. nov., C. lupini sp. nov., C. mallowi sp. nov., C. promethei sp. nov., C. sandiegoae sp. nov., C. selinae sp. nov., C. soloi sp. nov., C. songae sp. nov., C. swiperi sp. nov., C. thrymi sp. nov., C. tikoloshei sp. nov., and C. zorroi sp. nov. After our taxonomic treatment, the genus Ceroptres includes 43 species, all but three of which are known from North America. Among our new species are two reared from cecidomyiid midge galls, an association previously recorded but without valid taxonomic association. We provide new records for two additional previously described species; we record C. ensiger (Walsh, 1864) from Pennsylvania and confirm characters for the male, and we record C. lanigerae Ashmead, 1885 from Texas. We also examined several putative species corresponding to either C. cornigera Melika & Buss, 2002 and/or C. frondosae Ashmead, 1896, which we regard as a species complex that requires elucidation in future studies. To enable further studies on Ceroptres, we provide an updated key to North American females. Overall, we find that species of Ceroptres are host specialists associated with a single host gall species or several galls that are phylogenetically or ecologically related. We suggest that there are many North American species of Ceroptres, possibly hundreds, still awaiting collection and characterization.

    Abstract We investigate the species-level taxonomy and evolutionary history of Nearctic ants in the Crematogaster scutellaris group (Hymenoptera: Formicidae), drawing on evidence from morphology and UCE (ultraconserved element) phylogenomics. The New World species in this group form a well-supported clade that originated in the Late Miocene (~7.3 Mya) and subsequently diverged into three major lineages: the C. coarctata clade (south-western Nearctic), the C. opaca clade (south-western Nearctic and northern Neotropics) and the C. lineolata clade (eastern Nearctic and Caribbean, with four isolated south-west endemics). We hypothesize trans-Beringian dispersal into the New World, west-to-east movement within North America and restriction of mesophilic species to the east with increasing aridification of the west. The ancestral nesting behaviour of these ants is inferred to be ground-dwelling, and this is still the predominant condition in the arid west, whereas most species in the eastern United States are arboreal. We resurrect from synonymy nine species and describe three new species: C. detecta sp. nov. (from Nevada), C. parapilosa sp. nov. (Florida) and C. vetusta sp. nov. (Arizona). We provide a worker-based key to the 34 species of Crematogaster occurring in America north of Mexico, but emphasize that there are still ongoing taxonomic issues that need to be resolved.

    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.

    This study presents a comprehensive taxonomic revision of the family Suberitidae (Porifera: Demospongiae) for California, USA. We include the three species previously known from the region, document two additional species previously known from other regions, and formally describe four new species as Pseudosuberites latke sp. nov., Suberites californiana sp. nov., Suberites kumeyaay sp. nov., and Suberites agaricus sp. nov. Multi-locus DNA sequence data is presented for seven of the nine species, and was combined with all publicly available data to produce the most comprehensive global phylogeny for the family to date. By integrating morphological and genetic data, we show that morphological characters may be sufficient for regional species identification but are likely inadequate for global classification into genera that reflect the evolutionary history of the family. We therefore propose that DNA sequencing is a critical component to support future taxonomic revisions.

    The whip spider family Charinidae Quintero, 1986 is the most speciose and widely distributed in the arachnid order Amblypygi Thorell, 1883. It comprises three genera and 95 species distributed across all tropical continents and the eastern Mediterranean. Despite recent advances in the taxonomy of the family, a global revision of all its species, necessary to advance understanding of its systematics, biogeography and evolution, has never been conducted. In the present contribution, the family is revised in its entirety for the first time, including all previous names and 33 new species, 24 in the genus Charinus Simon, 1892: C. alagoanus sp. nov., C. apiaca sp. nov., C. carinae sp. nov., C. carioca sp. nov., C. carvalhoi sp. nov., C. cearensis sp. nov., C. diamantinus sp. nov., C. euclidesi sp. nov., C. goitaca sp. nov., C. guayaquil sp. nov., C. imperialis sp. nov., C. loko sp. nov., C. magalhaesi sp. nov., C. miskito sp. nov., C. mocoa sp. nov., C. monasticus sp. nov., C. palikur sp. nov., C. perquerens sp. nov., C. puri sp. nov., C. renneri sp. nov., C. sooretama sp. nov., C. souzai sp. nov., C. susuwa sp. nov., C. una sp. nov.; eight in the genus Sarax Simon, 1892: S. bilua sp. nov., S. dunni sp. nov., S. gravelyi sp. nov., S. indochinensis sp. nov., S. lembeh sp. nov., S. palau sp. nov., S. rahmadii sp. nov., S. tiomanensis sp. nov.; and one in the genus Weygoldtia Miranda et al., 2018: W. consonensis sp. nov. Taxonomic keys to the 132 species (excluding four nomina dubia) are presented and several taxonomic rearrangements implemented. Four subspecies are elevated to species level: Charinus cavernicolus Weygoldt, 2006, C. elegans Weygoldt, 2006, C. longipes Weygoldt, 2006, and Sarax bispinosus (Nair, 1934). Sarax batuensis Roewer, 1962 is removed from synonymy with Sarax buxtoni (Gravely, 1915) and S. buxtoni newly synonymized with Sarax rimosus (Simon, 1901). Stygophrynus moultoni Gravely, 1915 is transferred to Sarax, resulting in Sarax moultoni (Gravely, 1915) comb. nov. Ten species are transferred from Charinus to Sarax, resulting in new combinations: S. abbatei (Delle Cave, 1986) comb. nov., S. bengalensis (Gravely, 1911) comb. nov., S. dhofarensis (Weygoldt, Pohl & Polak, 2002) comb. nov., S. ioanniticus (Kritscher, 1959) comb. nov., S. israelensis (Miranda et al., 2016) comb. nov., S. omanensis (Delle Cave, Gardner & Weygoldt, 2009) comb. nov., S. pakistanus (Weygoldt, 2005) comb. nov., S. seychellarum (Kraepelin, 1898) comb. nov., S. socotranus (Weygoldt, Pohl & Polak, 2002) comb. nov. and S. stygochthobius (Weygoldt & Van Damme, 2004) comb. nov.
