The H. apoklinousa species-group

Diagnosis. The male genitalia of the species-group are characterized by the relatively narrow medial costal process consisting of two trigonal lobes with blunt tips, of which the distal one is larger and serrulate; the elongate and serrulate distal section of costa (Fig. 51), the large membranous lobe of valva, the relatively short, hook-like curved distal saccular process, the aedeagus lacking distal sclerotized protrusions to the vesica, the strongly elongate medial ventral diverticulum of vesica bearing a robust cornutus with a massive, elongate base, which is equal in length or longer than the cornutus itself. The female genitalia are characterized by the narrow and elongate corpus bursae with a lateral longitudinal cluster of shortly spinulose scobination and the large, sack-like appendix bursae.
