A new species of Acanthoscelides Schilsky (Coleoptera: Bruchidae) from Mexico with some biological notes

A new species of Acanthoscelides collected in Chiapas, Mexico is described and figured. Rhynchosia precatoria is cited as a new host plant record for A. dani sp.n and A. flavescens Fahraeus. The braconid Heterospilus prosopidis Viereck was found as parasitoid of both species of bruchids.

New Distribution and Host Records for the Genus Zabrotes Horn (Coleoptera: Bruchidae)

Since Romero and Johnson (2004a) published their checklist of the Bruchidae of Mexico, there have been very few contributions with respect to this group (Romero and Johnson 2004b). After checking the bruchid collections in Colección Nacional de Insectos, Instituto de Biología, UNAM, Mexico (CNIN), Jesús Romero Nápoles collection (CEAM), and Florida State Collection of Arthropods, Florida, USA (FSCA), we discovered ten new distribution records and two new host records for species in the genus Zabrotes Horn.

Cardonal-Nicolas Flores, 12/VI/2004, 2365 m, Romero N.J., 20°43′53′′N, 99°07′19′′W, CEAM (1 ex); Tlaxcala, Camino San Marcos, Huaquilapan, 23/VIII/2003, Lopez G.T.E., beating Quercus frutex, CEAM (1 ex).
