Type-species — Lepturginus obscurellus Gilmour, 1959 (original designation). Diagnosis. From the original description: “Small, elongate, subovate… Antennae elongate and slender, nearly twice as long as the body… third segment shorter than scape… Pronotum transverse, almost parallel-sided, bearing on each side at about the basal quarter a small, slender, almost porrect, acute spine… Elytra elongate subovate; apices obliquely-truncate, sutural angle rounded, marginal about rectangular; disc smooth, feebly depressed premedially. Prosternal process fairly narrow, about a quarter the breadth of a procoxal cavity… mesosternal process narrow, narrowing to the apex, narrower than the prosternal, narrowly rounded apically…” Number of species currently included: 2 (both from Mexico and Central America ). Remarks. Unfortunately, Gilmour (1959a) did not inform if the row of punctures on transverse basal sulcus of the pronotum continues or not laterally behind the lateral tubercles of the prothorax. However, as he knew very well the difference between Lepturges and Urgleptes (see Gilmour 1959d ), probably the punctures do not follow toward sides of the prothorax. If the punctures follow toward sides of the prothorax, Lepturginus will be a junior synonym of Urgleptes .
