A new species of Anomala Samouelle, 1819 from the amychodes species-group from North Vietnam with comments on A. levilinea Prokofev, 2021 (Coleoptera: Scarabaeidae: Rutelinae)

Abstract

Anomala laokayensis sp. n. from Lao Cai Province of North Vietnam is described, similar to A. amychodes Ohaus, 1914 but difers from this species in the details of the pronotal puncturation, shape of the aedeagus and male’s protarsal claw. Diferential diagnosis of the new species: dorsal surface not setose; pronotal puncturation rough and dense, no glabrous longitudinal strip on disc; parameres short and nearly rectangular, inner distal margin of left paramere forming a separate valve somewhat refexed outward; right paramere with vertical distal margin, lacking lateral process, with long and almost vertical medial process, basal plate narrowed toward apex and smoothly and broadly rounded apically; phallobase weakly infated. Variation in A. levilinea Prokofev, 2021 in light of discovery of a new specimen belonging to this species is discussed.
