Passalus (Pertinax) connatus Luederwaldt, 1941

Diagnosis: Anterior frontal edge straight without secondary mediofrontal tubercles; mediofrontal area slightly transverse and punctuated anteriorly; robust central tubercle with slightly free apex; mediofrontal+laterofrontal tubercles similar and close to inner tubercles; strong posterior frontal ridges; narrow ocular canthus with rounded apex; anterior pronotum angles rounded; anterior marginal groove at 2/3 of the pronotal width; prepisternum with conspicuous setae; pubescent humeri and epipleura; metasternum densely punctuated lateroposteriorly; pubescent metasternal lateral groove.

Remarks: Indicated by the author as fused elytra, in the description only one specimen from Mexico is cited, without further details. We examined the holotype, only labeled “ Mexico ” and deposited in the MZUSP-Brazil collection. It presents as striking characteristics pubescent humeri and reduced wings, common characteristics in some Andean Passalus of Colombia and Ecuador. In the original description, Luederwaldt (1941) mentioned its proximity to Passalus affinis Percheron 1835 , an endemic species to Hispaniola ( Reyes-Castillo et al. 1995; Jiménez-Ferbans et al. 2015), from which it is distinguished by presenting the “élitros soldados” (soldered elytra). Reyes-Castillo (1985) cited P. connatus from Mexico, however, we doubt that it is found in that country, where to date a brachypterous Passalus has never been collected. We did not examinate the wing, but its habitus suggests it is hemibrachypterous.
