Jivaro Complex

Perkins 1980: 37

Five species were placed in the Jivaro Complex by Perkins (1980). That grouping now appears to be composite, and will require additional study to more accurately adduce relationships. As a first step, H. premordica is removed and placed in the Premordica Complex. The aedeagi of both H. jivaro and H. anaphora have two long setae on the dorsal surface ( Figs. 105–106). Likewise, both H. premordica and H. ecuadormica have two setae ( Figs. 116– 117). If these setae are truly indicative of a close relationship, then perhaps H. hyalina , which lacks these setae ( Fig. 107), should eventually be placed in another species complex.
