A Brief Review Of The New World Xestipyge Marseul (Coleoptera: Histeridae: Dendrophilinae: Paromalini) With Description Of A New Species From The Southwestern Usa, William B. Warner

Insecta Mundi

New World species of the histerid beetle genus Xestipyge Marseul (Coleoptera: Histeridae: Dendrophilinae: Paromalini) are reviewed, and X. skelleyi, new species, is described. A dichotomous key and illustrations are provided as identification means for the now five included species from the Western Hemisphere.

Xestipyge was erected by Marseul (1862) as a monotypic subgenus of his genus Carcinops for “Carcinops radula Marseul” because of its unusual elytral striae, with fourth dorsal stria arched over the fifth dorsal stria and con­necting to the sutural (= sixth dorsal) stria. Lewis elevated Xestipyge to generic status in 1905. In addition to the different …

Two New Scarab Beetles From The Southwestern Usa (Coleoptera: Scarabaeidae: Melolonthinae And Aphodiinae), William B. Warner

A New Genus And Species Of Tiger Beetle, Pseudocollyris Shooki (Coleoptera: Cicindelidae), From Yunnan, China, Wen-Xuan Bi, Jürgen Wiesner

Insecta Mundi

A new genus, Pseudocollyris Bi and Wiesner, is established for the new species Pseudocollyris shooki Bi and Wiesner (Coleoptera: Cicindelidae), from Western Yunnan, China. A description, diagnostic features and illustrations of habitus are provided.

In 2017, the first author collected one remarkable tiger beetle during a survey in Western Yunnan, China. The beetle shows an elongated body, a metallic purple elytral surface with a pair of bright median spots and coarse punctation. Such appearance superficially resembles species of the tribe Collyridini (e.g. Collyris Fabricius, 1801 or Neocollyris Horn, 1901). However, detailed investigations of the beetle indicate it belongs to …

Insecta Mundi

Aphelocerus thomasi Rifkind, new species (Coleoptera: Cleridae: Clerinae), is described from the state of San Luis Potosí, Mexico. This beetle is named for the late Michael C. Thomas, in recognition of his lifetime of contributions to the study of Coleoptera.

Genomic Evidence Suggests Further Changes Of Butterfly Names, Jing Zhang, Qian Cong, Jinhui Shen, Pal A. Opler, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Further genomic sequencing of butterflies by our research group expanding the coverage of species and specimens from different localities, coupled with genome-scale phylogenetic analysis and complemented by phenotypic considerations, suggests a number of changes to the names of butterflies, mostly those recorded from the United States and Canada. Here, we present evidence to support these changes. The changes are intended to make butterfly classification more internally consistent at the genus, subgenus and species levels. That is, considering all available evidence, we attempt to assign similar taxonomic ranks to the clades of comparable genetic differentiation, which on average is correlated with …

Reinstatement Of Andrena Vernalis Mitchell (Hymenoptera: Andrenidae) From Synonymy With A. Ziziae Robertson, Zachary M. Portman, Ian G. Lane, Gabriella L. Pardee, Daniel P. Cariveau

The Great Lakes Entomologist

Andrena (Micrandrena) ziziae Robertson, 1891 (Andrenidae) is a well-known species found in a variety of habitats in the eastern and central United States and adjacent southern Canada. Andrena (Micrandrena) vernalis Mitchell, 1960 was described from five female specimens in the eastern United States and was synonymized with A. ziziae by Ribble in 1968. Recently collected specimens from throughout Minnesota have revealed that A. ziziae sensu Ribble is actually two species, one of which matches A. vernalis. Here, we reinstate A. vernalis as a valid species and describe the previously unknown male. We provide diagnostic characters …
