Subfamily Anaspidinae

Adults of Anaspidinae are distinguished from those of Scraptiinae by having the pronotum and elytra (at least basally) with transverse strigae, the head with a distinct transverse carina separating the occiput from the posterior face of the head capsule and abutting the prothorax, the protrochantins concealed (rarely partially visible in some Anaspis ), the pronotum lacking a posterior pair of pits or depressions, and being generally more hypognathous, well sclerotized, and appearing glabrous ( Crowson 1955; Lawrence and Ślipiński 2010; Pollock 2002). Male genitalia of North American Anaspidinae exhibit a modified tenebrionoid male aedeagus. The fused parameres of the tegmen possess a pair of articulated processes, the accessory lobes (“lateral lobes” of some authors), which are also known to occur in a number of other tenebrionoid families ( Lawrence and Ślipiński 2013; Spilman 1952). Larval Anaspidinae are easily distinguished from Scraptiinae by having a single pair of stemmata, possessing a distinct frontoclypeal suture, having a reduced mandibular mola with a brush of stout spines at the base, having a distinct lobe or uncus on the inner angle of the maxillary mala, and by having paired urogomphi but lacking a dehiscent process attached to the ninth abdominal tergite ( Crowson 1955; Švácha 1995; Young 1991). Only larvae of Anaspis have been characterized.
