Eucnemidae : Perothopinae

Head ( Lawrence et al., 2007, figs.26-31): Head capsule smooth (c84), undivided (c83), antennae located on surface as in all Elateridae , Cerophytidae , and Throscidae , in contrast to all other Eucnemidae (c85). Labrum fused to head as in all other discussed taxa except Phyllocerinae and Pseudomenini: Pseudomenini (c88). Number of antennomeres reduced as in all Eucnemidae except Phyllocerinae and Pseudomeninae and in contrast to Elateridae , Cerophytidae and Throscidae (c86).Mandibles with retinaculum as in Elateridae in contrast to other Eucnemidae and Cerophytidae andThroscidae (c97),free, elongate and inwardly curved biting as in Pseudomenini, Phyllocerinae , Anischiinae and most Elateridae , different from those of Throscidae and Cerophytidae as well as oth- er Eucnemidae . Maxillolabial complex contiguous with epicranium on each side but incapable of movement, as in Cerophytidae , Throscidae , Pseudomeninae and Anischiinae , contrary to other Eucnemidae (completely fused) and Elateridae (freely movable). Presternum subtriangular, lightly pigmented, with paired oblique endocarinae, similar to that of Phyllocerinae , Pseudomeninae , Anischiinae and Palaeoxeninae . Legs five-segmented as in Phyllocerinae , Pseudomeninae and Elateridae , Cerophytidae and Throscidae , but in contrast to those of other Eucnemidae , which are tiny and either one segment ( Anischiinae ) or with seta in place of leg. Abdominal segments without microtrichial patches and areoles as in Elateridae , Cerophytidae , Throscidae , contrary to other Eucnemidae except Phyllocerinae . Segment IX with small, simple urogomphi. Spiracles with closing apparatus as in other Eucnemidae , all Cerophytidae and Throscidae , in contrast to Elateridae .
