- Comments: Heterelmis debilis sp. nov. can be easily differentiated from any other species of the genus by a feeble transversal and an oblique impressions on pronotum. The new species resembles H.obscura by the body shape and the presence of a transversal and an oblique impressions on pronotum but the latter has stronger impressions on pronotum, the body is more elongated, besides the differences in the male genitalia. It is also similar to H. apicata (Grouvelle, 1896) by the pattern of the male genitalia, however the aedeagus of the latter is thiner, without row of setae on parameres and its pronotum does not present any kind of impression.
- Heterelmis obscura was described by Sharp (1882) to Guatemala and Grouvelle (1889) recorded it from Brazil (Santa Catarina State). According to Grouvelle, these specimens are less elongated than the Central American specimens. The type lectotype of H. obscura and the Grouvelle's collection, both housed at MNHN (Paris), were studied.The Brazilian specimens of "H. obscura" det. by Grouvelle (1889) are actually a new species, here described and named Heterelmis debilis sp. nov. For this reason, H. obscura has its geographic distribution restricted to Costa Rica, Guatemala, Mexico and Peru (Jach et al., 2016).
