abstract

  • Two species occurring in southeastern Texas, USA, of the predominately tropical genus Agra Fabricius, 1801 are described as new: oblongopunctata group - Agra rileyi Erwin, new species (type locality: Cameron County, Paloma Blanca Road, near Sabal Palm Sanctuary); and truquii group - Agra wickhami Erwin, new species (type locality: Cameron County, Brownsville). Both species are presently known from extreme southeast Texas in Cameron County, and A. rileyi was also found in Hidalgo and Starr Counties. Agra rileyi adults are associated with sabal palms (Sabal mexicana Mart., Arecaceae) and sugar hackberry trees (Celtis laevigata Willd., Ulmaceae). Agra wickhami is also known from the Yucat an peninsula. Adults of both species have been incorrectly identified in the past in collections and in the literature as Agra oblongopunctata Chevrolat, which occurs only in southern Mexico and Guatemala. A new group, truquii species-group, is established. Many specimen labels studied indicate that "beating vegetation" was used to acquire adult individuals. Thus, like members of all known species of more southern Agra, these beetles are found on vegetation well above the ground.
