A new species of Atractomerus Duponchel y Chevrolat (Coleoptera: Curculionidae: Anthonomini) from the El Cielo Biosphere Reserve in northeastern Mexico

Abstract

A new species, Atractomerus tlatoani n. sp. (Coleoptera: Curculionidae: Anthonomini), is described from a series of specimens collected from the El Cielo Biosphere Reserve of northeastern Mexico. Characters that separate the species from members of the rest of the genus are: 1) the profemoral tooth large, simple and the anterior margin straight without a basal prominence; 2) elytral interstria 3 not prominent at the extreme base; 3) well-developed subbasal prominence on interstria 4 equal to or greater in elevation than anteromedian elevation on interstria 2; 4) basal patch of dark fuscous elytral scales that extends across interstria 2 and 3 and reaches subbasal prominence on interstria 4; and 5) penis in dorsal view laceolate in shape and apex without lateral apicoventral prominences
