Tepuidessus Spangler, 1981 View in CoL

Type species. Tepuidessus breweri Spangler, 1981 , by original designation.

Revised diagnosis for Tepuidessus . Black Bidessini with dorsal surface densely setose; clypeus not modified; occipital line absent; basal striae on pronotum and elytra absent or present; sutural line on elytron absent; longitudinal elytral carina on disc absent; basal epipleural transverse carina absent; metathoracic wings reduced to short membranous vestiges without any sign of venation ( Fig. 6 View FIGURE 6 ); median lobe simple, with narrowed apical part in ventral view; parameres two-segmented. Species inhabiting tepui plateaus in Venezuela.

Note that the presence/absence of pronotal and/or elytral striae has also been shown to possibly vary even within closely related species of other genera, e.g. Limbodessus Guignot, 1939 (see Balke et al. 2015).
