Pseudagrion (B) nubicum Selys, 1876
Bluetail Sprite

Synonyms:

  • scientific: P. tricorne Pinhey, 1967
  • vernacular: Nubian S. (Su, RL)

Type locality: Nubia, Sudan

Diagnosis

Male is similar to P. torridum by (a) antehumeral stripes and postocular spots present; (b) antehumesal stripes green to blue; (c) apex of penis notched; (d) cerci small, not scoop-shaped; (e) cerci with prominent flange (long and wide wing-like internal ridge) bearing 1-2 teeth, including 1 in basal half; (f) paraprocts small, only weakly upturned. However, differs by (1) being widespread; (2) cerci parallel (rather than dicerging strongly), flange narrow, rather than very broad, with 1 (southern: Zambia, Zimbabwe) or 2 (further north) small teeth (dorsal view); (3) apex of cerci with mouth-like notch (lateral view), rather than with drawn-out point.
