Catalabus kryzhanovskyi sp. n., a new species of the leaf-rolling weevils (Coleoptera: Attelabidae) from Northern Vietnam

Abstract

A new species Catalabus kryzhanovskyi sp. n. (Coleoptera: Attelabidae: Attelabinae: Attelabini: Paramecolabina) is described from Northern Vietnam (Yên Bái Province). This species is similar to C. barsevskisi Legalov, 2019 from Vietnam (Kon Tum Province), but differs in the reddish-brown elytra, pronotal constrictions with bronze sheen, non-rugose elytral interstriae, narrower metepisternum, weakly developed basal sclerite, stronger sclerotized lower sclerites with smooth top edges. The new species is distinguished from the Vietnamese C. quadriplagiatus (Voss, 1953) and C. sexplagiatus (Heller, 1922) in the elytra without pale spots, more delicately sculpted pronotum and elytra, wider pronotum with sharper pro- and postnotal constrictions, and thicker profemora. This is the second record of the representative of the subgenus Catalaboides Legalov, 2003 in Vietnam
