Eucnemidae : Anischiinae

( Fig. 2F )

Head capsule elongate, flattened, smooth (c84), undivided (c83), antennae located in deep pits as in all Eucnemidae except Perothopinae (c85), in contrast to all other discussed taxa ( Fig. 2G ). Labrum fused to head without trace of suture as in all Eucnemidae except Phyllocerinae and Pseudomenini (c88). Number of antennomeres reduced as in all Eucnemidae except Phyllocerinae and Pseudomeninae , in contrast to Elateridae , Cerophytidae and Throscidae (c86). Mandibles without retinaculum as in other Eucnemidae except Perothopinae as well as Cerophytidae and Throscidae (c97), free, elongate and inwardly curved as in Schizophilini , Perothopinae and most Elateridae , different from those of Throscidae and Cerophytidae as well as other Eucnemidae . Maxillolabial complex contiguous with epicranium on each side and incapable of movement, as in Cerophytidae , Throscidae , Pseudomeninae and Perothopinae , contrary to other Eucnemidae (completely fused) and Elateridae (freely movable) (c100). Presternum subtriangular, lightly pigmented, weakly delimited, with paired oblique endocarinae. Legs with one segment, a unique feature. Abdominal segments with microtrichial patches, without areoles. Spiracles with closing apparatus as in other Eucnemidae , all Cerophytidae and Throscidae , in contrast to Elateridae .
