Leptelmis Sharp, 1888: 243.
Leptelmis gracilis Sharp, 1888.
Leptelmis is characterized by the combination of the following characters: 1) body (Figs 2D, 8E) narrow, elongate; 2) antennae with segments 3–10 filiform; segment 11 longer; 3) surface of the pronotum (Figs 2D, 5D, 8E) coarse to moderately smooth; anterolateral angles moderately produced; sides arcuate before and after lateral constriction; carinae absent; median groove absent; complete transverse impression in apical half; 4) surface of the elytra (Figs 2D, 8E) moderately smooth; sides subparallel in basal 2/3, then tapered into rounded apex; carinae absent; intervals markedly impressed, nearly flat to slightly raised; 5) prosternum moderately long in front of procoxae; anterior margin almost straight, laterally lowered without distinct indentation; prosternal process wide with broadly rounded apex (Fig. 12D); 6) legs with femora stout to almost spindle-shaped, tibiae without apical fringes, tarsal claws (Fig. 14M) with one basal tooth.
Leptelmis is closely related to Stenelmis, sharing the lack of cleaning fringe on the inner margin of the protibia and a similar body shape. However, it is distinguished by a pronotum constricted by a complete transverse impression in the apical half, the absence of a median groove, and longer legs.
