Geocharidius Jeannel

Geocharidius Jeannel, 1963: 107 (type species Anillus integripennis Bates, 1882, by original designation)

Recognition.

The members of this genus are distinguished from those of the other North and Central American Anillina by the following combination of characters: frontal area of head with small median tubercle; maxillary palps with palpomere 4 shorter than 1/4 that of palpomere 3; labial ligula without paraglossae, mentum and submentum separated by mental-submental suture; pronotum convex, with short vestiture throughout, including the areas forward of the lateral setae; elytra without fixed discal setae and with the 7th and the 8th and the 8th and the 9th pores of the umbilicate series separated by equal distances; metendoventrite linear without lateral arms; and intercoxal process between the hind legs widely triangular ( Sokolov 2013).

Included taxa.

The species of Geocharidius , as treated at present ( Lorenz 2005), are arranged in two groups, based on body form: those with a subdepressed form and those with a globose habitus ( Erwin 1982). Species with members subdepressed in habitus (Fig. 2 A–C) correspond to the type species of the genus and are treated below as the integripennis species group. Members of the genus with a globose habitus (Fig. 2D), like Geocharidius phineus Erwin, Geocharidius romeoi Erwin and similar undescribed species, are not treated in this report.
