Systematics: The first-instar nymph of Ac. arenosus is most similar to the first-instar nymph of Ac. coccineus in having the dorsal medial and mediolateral enlarged setae noticeably smaller than the lateral enlarged setae, the predominant multilocular pores with three loculi, and the ventral lateral enlarged setae increase in size anteriorly. The species differ as follows (character states in brackets are of Ac. arenosus): dorsomedial and mediolateral enlarged setae cylindrical (predominantly conical); each femur with five setae (each femur with four setae). (Miller & Stocks, 2022)
Structure: Adult female elongate to oval. Body varies from gray to light purple. Smooth, heavy, white ovisac may be intermixed with grains of sand (Miller, 1991).
