The D. recta species-group
The group is characterized by the combination of the following features: (1) the uncus is arrowhead-shaped and has a longitudinal dorsal crest; (2) the juxta is wide (in proportion to the genital capsuleās size) and well-sclerotized with broad and rounded lateral lobes and a V-like dorsal process medially; (3) the sacculus is evenly dilated distally, its distal process is pyramidal, heavily sclerotized and armed with several long robust setae apically (Singh et al. 2019).
