A new species of Bathynellidae is described from Colorado (USA). Hobbsinella gunnisonensis Camacho & Taylor sp. nov. displays a unique combination of morphological characters including seven-segmented antenna lacking medial seta on exopod, antennule slightly longer than antenna, three-segmented mandibular palp, four articles on endopod of thoracopods I to VII and five spines on sympod and three spines on endopod of the uropods. Partial sequences of cytochrome oxidase I (COI) and 18S have been obtained from several specimens of the new species. The mitocondrial and nuclear DNA data complement the traditional morphological taxonomic description support the validity of the new species. Molecular data for the Bathynellidae demonstrate the presence of two highly divergent genetic units, with the new species placed in the genus Hobbsinella. With the description of Hobbsinella gunnisonensis Camacho & Taylor sp. nov. and its molecular characterization, we discovered an interesting distribution of the genus, which occurs in both sides of the Continental Divide (Texas and Colorado) and different habitats.
Leptoconops Skuse and Culicoides Latreille (Diptera: Ceratopogonidae) biting midges are serious pests of mammals, birds, and reptiles and important vectors of viruses, protozoans, and filarial nematodes. Their collection became an important adjunct to mosquito surveillance using light-baited and CO2-baited suction traps in Grand County, Utah, United States, during 1999–2016. During 2017–2020, collecting was expanded to California, Nevada, Idaho, Wyoming, Colorado, Arizona, New Mexico, and other parts of Utah using an ultraviolet light suction trap. As a result, five species of Leptoconops and 59 species of Culicoides, representing Leptoconops subgenera Holoconops Kieffer and Leptoconops Skuse, Culicoides subgenera Amossovia Glukhova, Beltranmyia Vargas, Diphaomyia Vargas, Drymodesmyia Vargas, Haematomyidium Goeldi, Monoculicoides Khalaf, Selfia Khalaf, Sensiculicoides Shevchenko, Silvaticulicoides Glukhova, Silvicola Mirzaeva and Isaev, and Wirthomyia Vargas, and the Culicoides Leoni, Limai, Palmerae, Piliferus, Saundersi, and Stonei species groups, were collected. Keys to adult males and females and tables of diagnostic characters are provided for identification of 15 species of Leptoconops and 86 species of Culicoides collected, reported by others, or likely to occur in the Southwestern United states west of the Continental Divide. Description references, synonymies, diagnoses, geographic and seasonal distributions, and biological summaries from the available literature are provided. Data on relative abundance in light-baited or CO2-baited traps are provided for the species collected. Intersex specimens and specimens parasitized by mites or mermithid nematodes are tabulated. Culicoides (Drymodesmyia) bakeri Vargas is reported from California (new United States record). New state records of other species for Idaho, Nevada, Utah, Colorado, Arizona, and New Mexico of the United States and for the Mexico states of Puebla, San Luis Potosi, and Oaxaca are reported. Culicoides salihi Khalaf is assigned to the subgenus Diphaomyia of Culicoides (new status). Culicoides stellifer (Coquillett) is reassigned to the subgenus Haematomyidium of Culicoides (new status). Culicoides travisi Vargas is assigned to the subgenus Sensiculicoides of Culicoides (new status). Culicoides luglani Jones and Wirth is reassigned to the Culicoides Limai group (new status). Confusion over species limits was evident between Culicoides cacticola Wirth and Hubert and Culicoides torridus Wirth and Hubert, between C. travisi and Culicoides kibunensis Tokunaga, between Culicoides doeringae Atchley and Culicoides lophortygis Atchley and Wirth, between Culicoides owyheensis Jones and Wirth and Culicoides mortivallis Wirth and Blanton, and between Culicoides cockerellii (Coquillett), Culicoides neomontanus Wirth, and Culicoides sierrensis Wirth and Blanton. Several new species, hybrids, or variants of Culicoides are diagnosed but not formally described: two of subgenus Silvicola, one of the Palmerae group, two of the Piliferus group, and one unplaced to subgenus or species group.

Parajulid milliped studies XI : Initial assessment of the tribe Gosiulini (Diplopoda: Julida)
(2016)
The parajulid milliped tribe Gosiulini (Diplopoda: Julida) comprises two genera – Gosiulus Chamberlin, with three projections on the posterior gonopod and two species in the southcentral/southwestern United States (US) [Arizona, Colorado, New Mexico, and Texas], and monotypic Minutissimiulus Shelley, n. gen., with two projections, in Nuevo León, Mexico. Gosiulus conformatus Chamberlin occupies the plains/fl atlands of Texas, while its congener inhabits high elevations to the west in all four US states. Both are anticipated in Mexico (Coahuila, Chihuahua, and Sonora), and G. conformatus is expected in southeastern Colorado, eastern New Mexico, and the Oklahoma panhandle. The eastern boundary of G. conformatus and the genus/tribe conforms to the western border of the Piney Woods biome in eastern Texas. As shown by the posterior gonopod drawing in the original description, Parajulus timpius Chamberlin, previously considered of “uncertain generic position or validity,” is unquestionably the oldest name for the western species. The anteriormost posterior gonopod projection, absent from Minutissimiulus, is considered the “prefemoral process,” while the “solenomere” and a third branch arise from a common base.
Because of positional homology with “process ‘C’” in Nesoressini, the last projection is accorded this name, which may also apply to the “prefemoral process” in Aniulini. Minutissimiulus biramus Shelley, n. sp., is proposed along with the following new subjective synonymies: Apacheiulus Loomis under Gosiulus; Ziniulus aethes and Z. medicolens, both by Chamberlin, and Z. ambiguus and Z. nati, both by Loomis, under G. conformatus; and A. pinalensis and A. guadelupensis, both by Loomis, under G. timpius, new combination. Ziniulus navajo Chamberlin becomes an objective synonym of P. timpius because its holotype is designated neotype of the latter. Minutissimiulus biramus Shelley is the fi rst Mexican gosiuline and “mainland” Mexican parajulid not in the tribe Parajulini.
