A taxonomic review of the Selenophori group (Coleoptera, Carabidae, Harpalini) in the West Indies, with descriptions of new species and notes about classification and biogeography.

ZooKeys 2017
Primarily a taxonomic review of the West Indian elements of the selenophorine Harpalini, this paper includes a classification, a key, descriptions and illustrations of taxa, re-rankings, and new synonymies. In total, 45 species and subspecies are treated, six of which are described as new. A new genus and new species are as follows, with type localities in parentheses: Paraulacoryssus gen. n. , (type species Selenophorus puertoricensis Mutchler, 1934); Neodiachipteryx davidsoni sp. n. , (Zamba, Dominican Republic); Selenophorus spinosus sp. n. , seriatoporus species group (Benjamin Constant, state of Amazonas, Brazil); Selenophorus obtusoides sp. n. , parumpunctatus species group (near Soroa, Pinar del Rio Province, Cuba); Selenophorus iviei sp. n. , nonseriatus species group (Big River, Montserrat, 16°45.719N', 62°11.335W'); Selenophorus irec sp. n. , nonseriatus species group (Vernou, Guadeloupe, Lesser Antilles); and Selenophorus fabricii sp. n. , opalinus species group (Cabo Rojo, Pedernales Province, Dominican Republic). This last species was misidentified as Selenophorus integer (Fabricius). In turn, that species was misidentified as Selenophorus chalybeus Dejean. Selenophorus chalybeus Dejean is a junior synonym of Selenophorus integer Fabricius, syn. n. ; and Isopleurus macleayi Kirby is a junior synonym of Selenophorus pyritosus Dejean, syn. n. Biogeographically, log of land area plotted against log of number of species shows that the equilibrium theory of biogeography applies to the West Indian selenophorine fauna. Taxonomically, the selenophorine taxa of the West Indies are arranged in eight genera. The 30 species/subspecies of Selenophorus ( sensu stricto ) are arranged in 10 species groups. Geographically, the major sources of the selenophorines are the Bahamas, the Greater Antilles and Lesser Antilles. The West Indian islands probably have been invaded by 26 taxa. Of the currently extant taxa, 11 are classified as immigrant , meaning that they are represented both in the islands and on the mainland (South America or Middle America and southern Florida). Thirty three taxa are classified as precinctive , meaning that they originated where they are now living, the implication being that they have descended from immigrants, thus older in the islands than the current-day immigrants. It is postulated that the West Indian taxa represent three age groups: oldest, ancestors having reached the proto-Antilles by a landspan known as GAARlandia; a middle-age group (Neogene period), their ancestors having reached the islands by dispersal over water, between islands; and a young group of extant taxa, no older than the Pleistocene, also having reached the islands over water.
