New larval descriptions and biology of some New World Anomalini beetles (Scarabaeidae: Rutelinae)

Abstract

The third-instar larvae of four Anomala species: A. cincta Say, A. forreri Bates, A. sticticoptera Blanchard, and A. discoidalis Bates from Mexico are described and diagnostic characters of the species are illustrated. The third-instar of two Callistethus species: C. vidua (Newman) and C. cupricollis (Blanchard) from Mexico are also described and illustrated. The pupa of A. cincta is described. These six species are included in a key to the larvae of North American and Mexican Anomalini, which now includes four genera and 20 species. The use of larval morphology in the taxonomy of Anomalini is briefly discussed. Data on larval biology and life cycle of the six species are also provided.
