The Trilepis-type can be derived from the Carex-type by a flattening of the scutellum and a shifting of the root cap to a subbasal position (Fig.
Thorax black; pronotum black, hexagonal, with a median carina strongly marked; pronotum with anterior margin straight, lateral-anterior margins straight, lateral posterior margin slightly sinuous, posterior margin grooved; scutellum brownish with slight central concavity, with horizontal grooves strongly marked; tegmina black, apical plexus of veins developed; hindwings hyaline with dark brown venation, vein Cu1 not thickened at base; legs black; metathoracic tibia with two lateral spines (basal spine equal in size to spines in apical crown; apical spine larger than spines in apical crown); apical crown of spines on tibia consisting of two rows; basitarsus with two rows of spines covered by long setae; subungueal process present and quadrangular.
Thompson and Ghorpade (1992) differentiated this species by the presence of serrate on posterior margin of scutellum, first abdominal tergite being medially reddish and hind femora yellow with narrow dark brownish annulus, mesonotalpile short, wing hyaline.
This species somewhat resembles the cardiophorine Horistonotus uhlerii Horn (Coleoptera: Elateridae) [also present in southeastern USA), but the scutellum of that species is not anteriorly emarginate.
pertusicossis Fiedler, 1944 from Colombia by its rufous body, rostrum slightly curved, scutellum rhombic and apex of elytra not rounded.
Scutellum dark red-brown, largely apruinose except for silver anterior 1/3, fine dark red-brown setose (apical macrosetae poorly differentiated).
Explant source: Mature seeds were used as an explant source for callus induction from its scutellum. After callogenesis the seed and the elongated plumule were detached using sterile forceps and the whole chunk of each subsequent scutellum-derived callus was used as one explant for in vitro regeneration of multiple shoots.
Scutellum: Length 0.40, width 0.50, pale green, scutellar surface bearing scattered, semi-erect, simple golden setae only.
