Diagnosis

Within the globulus group, only D. benesi and D. ocellatopunctatus are brachypterous species. They are associated with mountain formations; Vaz-de-Mello and Nunes (2016) provided detailed descriptions for both species, and illustrated the tegmen of D. benesi . Therefore, herein the description of D. benesi is merely complemented by the inclusion of the following characters of the male genitalia: in dorsal view, paramera rectangular, onethird longer than its width at medial portion; apex slightly obliqualy truncate; surface with a feeble pre-apical longitudinal carina, inner edge curved inward at basal third ( Figure 4 View Figure 4 (a)); in lateral view, apical half of paramera approximately as wide as base; ventral sclerotised membrane between paramera thinner at basal half, slightly angulate laterally ( Figure 4 View Figure 4 (b)). ME with two hook-like projections inferiorly, projections separated by a broad U-shaped emargination; ME with a longitudinal fold at the median inferior region ( Figure 5 View Figure 5 (b)). Complex of A and A+SA endophallites thin, C-shaped in lateral view; SA endophallite with reticulate texture inferiorly ( Figure 5 View Figure 5 (h), arrow). FLP endophallite C-shaped in lateral right view, inferior region thinner than superior one; surface of the C-shaped region with irregular projections ( Figure 5 View Figure 5 (h)). SRP endophallite approximately J-shaped ( Figure 5 View Figure 5 (h)).
