A North American Biodiversity Hotspot Gets Richer: A New Species of Whirligig Beetle (Coleoptera: Gyrinidae) From the Southeastern Coastal Plain of the United States

A new species of Dineutus Macleay, 1825 is described from the Southeastern CoastalPlain of the United Sates. Habitus and aedeagus images as well as illustrations of elytralapices, protarsus, palps, and male mesopretarsal claws are provided for Dineutus shorti n.sp. and compared to those of D. discolor Aubé, 1838. The importance of theSoutheastern Coastal Plain as a biodiversity hotspot and the potential conservationconcern of D. shorti n. sp. also are discussed.

A New Species

This work provides a taxonomic survey of the North American species of the genus Elonus Casey, 1895 (Coleoptera: Tenebrionoidea: Aderidae). It includes the description of a new species, Elonus gruberi n. sp. from the United States, related to E. hesperus Werner, 1990 and to E. basalis (LeConte, 1855). A review and key to the North American species is provided.

A New Species

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791

Nearctic Region

Based on the geographic distribution database of the Orthoptera Species File, the diversity and distribution of the superfamily Grylloidea in the Nearctic region was studied using the statistics and Sorensen dissimilarity coefficient. A total of 164 species or subspecies belonging to 4 families, 9 subfamilies and 27 genera were recorded from this region; among which Gryllidae (93, 56.70%), followed by Trigonidiidae (44, 26.83%), Mogoplistidae (25, 15.24%), and Phalangopsidae (2, 1.22%). The diversity exhibits an asymmetric distribution pattern, with the southeastern coastal plain, the Interior Plateau and Piedmont of the United States was the most abundant. At the same time, the regional similarity of species distribution was analyzed, and the Nearctic was divided into four subregions: Boreal & Arctic zone of North America, Eastern temperate North America, Northeast temperate North America, and Southern North America & western temperate North America.
