Tribe Polydrepanini Jeekel, 1968

Diagnostic remark. Based on Golovatch (2014, 2015), contrary to the Alogolykini which typically shows a nearly fully to very strongly reduced gonofemorite, coupled with a basally originating, long, thick, mostly rod-like solenomere, the tribe Polydrepanini seems to be best characterized by a clearly elongate, mostly slender, sometimes twisted/helicoid gonofemorite (fe) and a more or less thin, mostly flagelliform, suberect, distal to subapical solenomere (sl) often forming a conspicuous loop/curve (k) near the base (e.g., Figs 3–8 ).
