Emended diagnosis

Troglomorphic members of Stygnopsinae , eyeless, similar condition as Mexotroglinus Šilhavý, 1977 , Toojah Cruz-López, in press, Chinquipellobunus madlae (Goodnight & Goodnight, 1967) and Serrobunus paulbryanti Aguiñaga & Cruz-López, 2019 . Troglostygnopsis has clear lateral areas on scutum, similar to Panzosus Roewer, 1949 , Paramitraceras , Philora , Sbordonia and Toojah; however, Troglostygnopsis can be distinguished from other eyeless genera with lateral projections on scutum by the presence of a dorsal row of large spiniform tubercles on pedipalpal femur; in fact, no other genus of the family whether troglobitic or epigean has this protruding row. Male genitalia have the Paramitraceras -pattern sensu Cruz-López & Francke (2013b): pars distalis tubular, with an apical depression where the follis arises, with many pairs of acute MS C on lateral sides, many pairs of spatulate MS A+B at the base and laterally on the pars distalis, two pairs of MS E, E1 small and in the middle of ventral side, E2 long and external to E1, and one or two pairs of MS D, near the base of follis. Troglostygnopsis can be differentiated from those genera with male genitalia with this pattern ( Paramitraceras , Panzosus , Philora and Sbordonia ) as follows: ocularium not pointing forward, pedipalps strongly armed with long spiniform setiferous tubercles, and males without glandular ventral tubercles on stigmatic area (in this last character similar to Sbordonia armigera Šilhavý, 1977 ).
