Antibothrus Sharp 1885

Systematics. Antibothrus is a predominantly Old World genus of cocoon-forming beetles with 17 described species ( Ślipiński et al. 1989). Most of the species occur in Madagascar and Africa ( Ślipiński 1982), but three species are known from Japan ( Sasaji 1997; Narukawa 2002; Aoki 2009), one from Russia ( Nikitsky 1985a, b), and one from Sri Lanka ( Sharp 1885).

Generic diagnosis. In America north of Mexico, this genus can be diagnosed by the following combination of characters (modified from Ślipiński et al. 1989) ( Fig. 1 ):

Small (less than 3 mm long), moderately to strongly convex. Head produced, eyes large, protuberant. Antennae 11-segmented with 2-segmented club, with terminal segment smaller than penultimate. Pronotum hexagonal in outline (although only vaguely so in A. morimotoi ). Elytra with alternate intervals carinate, even intervals usually punctate. Procoxae narrowly separated, intercoxal process produced into single lobe. Metaventrite and abdominal ventrite 1 without postcoxal lines. Tibiae expanded toward apices.
