Aplopsis sp., copyright Liz MacRaild.

Belongs within: Melolonthinae.

Aplopsis is an Australian genus of chafers with the body clothed by pale setae arising on the elytra from elongate, annulate punctures. Most species have a lateral ridge on the abdomen against which the elytra rest when closed, though this ridge is reduced or absent in the A. viridis species group (Britton 1957).

Characters (from Britton 1957, as Haplopsis): Anterior tibiae with basal tooth on outer edge situated on proximal half of tibia, the tooth small with its point directed towards apex of tibia; antennae with six to nine segments including a club of three lamellae. Body clothed with pale setae which are usually slender and pointed. Setae very regularly distributed except on elytra where they are arranged in longitudinal bands, with relatively narrow bare spaces between. Setae arising from characteristic elongate annulate punctures. Anterior edge of pronotal hypomera usually marked by a ridge or produced as a free edge enclosing a pocket for reception of antenna. Abdomen usually with a longitudinal ridge on sternites on each side, corresponding with outer edges of elytra; tergite and sternite of propygidium fused. Legs slender, posterior tibiae with or without a slight transverse setose ridge on upper side.
