A New Species of the Rhynchitid Genus Thompsonirhinus Leg. (Coleoptera, Rhynchitidae) from Vietnam

Abstract

Thompsonirhinus (Thompsonirhinus) weigelisp. n. from Vietnam is described and illustrated. It differs from other species of the genus Thompsonirhinus in the reddish brown elytra and brown abdomen. The new species is similar to Th. (Th.) decoomani Legalov, 2007 but differs in a longer rostrum, wider elytra with more strongly convex intervals, shorter arms of the arcuate sclerite and almost parallel margins of the bottom sclerite of the endophallus armament. From Th. (Th.) batangensis Legalov, 2007 the new species differs in the black head, insertion of the antennae near the middle of the rostrum, wider and more densely punctate pronotum, wider elytra with narrower intervals, and the endophallic armament.
