Xenopygus analis Erichson
Description
Xenopygus analis (Erichson)
(Figs. 22, 46)
Diagnosis. Xenopygus analis can be distinguished by the following characters: head, pronotum and elytra of metallic color; head and pronotum blue to greenish blue, coarsely and sparsely punctuated; elytra blue, finely and densely punctuated; abdomen shiny black with segments 7 and 8 golden-orange; antennal segments 6–10 transverse; disc of pronotum with two dorsal rows of punctures. Length 12.0– 14.5 mm.
Distribution. Widespread from Mexico to Argentina (Herman 2001; Newton, unpublished database).
Bionomics. Species belonging to Xenopygus have been frequently found in carrion, dung and decaying fruits (Irmler 1982; Navarrete-Heredia et al. 2002), also in leaf litter in the Eastern Cordillera of Colombia (Gutiérrez & Chacón 2006). Xenopygus analis was reported as predator of both larvae and pupae of Anastrepha spp. (Diptera: Tephritidae) (Navarrete-Heredia et al. 2002), also from ant nests (Gutiérrez & Chacón 2006).
