Intermediate Claspertail

Synonyms:

  • scientific: O. supinus Hagen in Selys, 1854 ssp. nigrotibialis

Type locality: Kilimanjaro, Tanzania

Diagnosis

Male is intermediate to pale and dark species of supinus-group of Onychogomphus by (a) labrum largely pale rather than black, but postclypeus at least partly dark; (b) broadly black on humeral stripe, this area at least as wide as flanking pale stripes; (c) all tibiae all black. Differs from darker O. seydeli and O. styx by (1) ranging from C Kenya to Ethiopia; (2) foliation on S8 deeper than that on S9, rather than about equally deep on both segments.
