Abstract Dung beetles of the Scarabaeinae subfamily are an essential component of the diversity of organisms that degrade organic matter in the soil. Therefore, their diversity provides critical ecological services to different ecosystems, including agroecosystems. This study describes the fauna of dung beetles (Scarabaeidae: Scarabaeinae) that inhabit cattle ranches in two municipalities of Tabasco, Mexico. From November 2018 to October 2019, 1,400 specimens of this subfamily were collected using pitfall traps baited with cattle feces on ranches located in Tacotalpa and Centro. The most abundant species were the introduced beetles Digitonthophagus gazella (Fabricius) and Euoniticellus intermedius (Reiche). This study shows a scarce presence of roller species and notable differences in the structures of dung beetle assemblages between ranches. Additionally, this study provides a record of nine undocumented species for Tabasco, bringing the total to 27 Scarabaeinae species for the state. This study is the first formal survey to document the diversity of these insects in Tabasco, Mexico.

Abstract Eight species of Trogossitidae, three of Peltidae, and one of Lophocateridae are reported from Montana. Of these, six represent new state records. Records of Tenebroides collaris (Sturm) represent a substantial new westward range extension; supported by additional new records from Colorado, this species appears to be established in the western Great Plains.

Abstract The firefly species Photuris pensylvanica (DeGeer) has been the source of much taxonomic confusion. The species name P. pensylvanica (also P. pennsylvanica) has been applied erroneously for decades and as a result, entomological collections and publications are replete with misidentifications. In the absence of type specimens, Herbert S. Barber applied the name P. pensylvanica to the diminutive Mid-Atlantic tidal marsh-inhabiting “dot-dash” flashing species in 1951. To stabilize the genus Photuris Dejean, we made a concerted effort to locate the original type series, including the holotype, but were unsuccessful. As such, we briefly summarize the history of the taxon, accept Barber's designation, provide the first modern description of the species, designate a neotype from the proper type locality of Wilmington, Delaware, USA, and review its confirmed distribution. Thus far, the name-bearing taxon is recognized only from the freshwater tidal lowlands of the Chesapeake Bay and Delaware Bay estuaries. The species should be looked for in freshwater tidal marshes both north and south of these estuaries.
摘要:萤火虫(Photuris pensylvanica, DeGeer)在分类上引起了许多混乱。种名P. pensylvanica(也叫P. pennsylvanica)几十年来一直被错误地使用，结果，昆虫学的收藏和出版物中充满了错误的识别。在缺少模式标本的情况下，赫伯特·s·巴伯(Herbert S. Barber)于1951年将这种居住在大西洋中部潮汐沼泽的小型“点划”闪光物种命名为P. pennsylvania。为了稳定Photuris Dejean属，我们共同努力定位原始模式系列，包括完整模式，但没有成功。因此，我们简要地总结了该分类群的历史，接受了Barber的命名，提供了该物种的第一个现代描述，从美国特拉华州威尔明顿的适当模式地点指定了一个新类型，并审查了其确定的分布。到目前为止，这个命名的分类群只在切萨皮克湾和特拉华湾河口的淡水潮汐低地被发现。该物种应该在这些河口北部和南部的淡水潮汐沼泽中寻找。

Abstract Tytthonyx milleri Ivie, Fanti, and Ferreira, new species (Cantharidae, Tytthonyxini) is described from Miocene Dominican amber. The new species is compared with the other two described fossil taxa of the genus, as well as two additional, undescribed Dominican amber cantharid species, and their morphology is discussed. A comparison of extant and fossil Tytthonyx LeConte and Caccodes Sharp is given.

Abstract We report the discovery of a new species in the recently revised genus Prespelea Park, Prespelea videns Caterino and Vásquez-Vélez, new species, from the Nantahala Mountains, North Carolina, USA. The new species has characters intermediate between two previously defined informal groups, one comprising wingless males with reduced eyes, one with apparently winged males with well-developed eyes. The new species is apparently flightless, but has moderately well-developed eyes. We assess its phylogenetic placement, using DNA and morphology, and find it to be sister to a clade comprising Prespelea myersae Caterino and Vásquez-Vélez and Prespelea enigma Caterino and Vásquez-Vélez. We provide a revised key to accommodate the new species, and offer some new distributional records for other species in the group.

Abstract A group of four North American dasytine species is carved from the genus Trichochrous Motschulsky, 1860. The genus Microasydates Gimmel and Mayor, new genus (type species: Pristoscelis umbratus LeConte, 1866) is created for these species. This new genus is clearly defined based on several adult male characters, including the presence of a field of coarse black setae concentrated medially on abdominal ventrite 4, slender tibial spurs in combination with the head not distinctly enlarged, lack of a basal strut on abdominal sternite VIII, tegmen membranous apically, and ventral teeth on the median lobe of the aedeagus. Species are distinguished primarily by characters of pronotal shape, setation, female pygidium, and the median lobe of the male aedeagus. Previously described are Microasydates punctipennis (LeConte, 1866), new combination and Microasydates umbratus (LeConte, 1866), new combination. Newly described are Microasydates sanclemente Gimmel and Mayor, new species and Microasydates santabarbara Gimmel and Mayor, new species. The only widespread mainland species is M. umbratus, which occurs almost throughout California across the Great Basin into Utah, while the remainder of the diversity is in the California Channel Islands and Santa Ynez Mountains in Santa Barbara County. Upon examination of type material, Trichochrous indigens Casey, 1895, Trichochrous nubilatus Casey, 1895, Trichochrous separatus Casey, 1895, Trichochrous suffusus Casey, 1895, Trichochrous testaceus Casey, 1895, and Trichochrous pratensis Blaisdell, 1924 are all considered new junior subjective synonyms of M. umbratus. Trichochrous fulvovestitus Casey, 1895, status restored, and its junior synonym, Trichochrous propinquus Casey, 1895, are removed from synonymy with M. umbratus and retained in the genus Trichochrous. Adults of Microasydates are active during mid to late summer, and aggregate, often in large numbers, on the flowers of a wide variety of mostly perennial plants, where they mate and apparently feed on pollen, nectar, and occasionally small arthropods. Seasonality data and known host plant associations are provided along with species treatments.

Abstract Postelichus bajaensis Barr and Shepard, new species is described and figured, and its habitat discussed. The first taxonomic key to the males of all seven species of Postelichus Nelson, 1989 is presented with images of the male genitalia. The geographic distributions of the species of Dryopidae occurring on the Baja California Peninsula of Mexico are reviewed. Helichus columbianus Brown, 1931 is reported as a new country record for Mexico and Postelichus immsi (Hinton, 1937) as a new record for Baja California.
