An unusual new genus of spider beetle (Coleoptera: Ptinidae) from a Guano island of Peru

Abstract

A new genus and species of spider beetle from Peru is described. One specimen is known to have come from South Chincha Island, while others were intercepted in a guano shipment in Texas, USA. Unusual characters of this genus include a small cavity laterally on each side of the metepisternum and very broad spacing between the antennae. The potential biology and evolutionary relationships of this genus are briefly discussed.
