Pseudagrion (B) sjoestedti Förster, 1906
Variable Sprite

Synonyms:

  • scientific: P. sjostedti
  • vernacular: Rufous S.; Sjoestedt's S.

Type locality: Bipindi, Cameroon

Diagnosis

Male is similar to P. rufostigma by (a) face usually reddish, sometimes yellow, postocular spots and antehumeral stripes often present; (b) at least tibiae pale, contrasting with femora when these are dark; (c) apical black often extends ventrally to sides of S8-9, segments may be pruinose; (d) lateral lobes of penis rounded or absent; (e) cerci with apical notch, or notch unclear; (f) paraprocts not hatchet-shaped and at most curved up weakly, with rounded apex, and if low knob present then apex is long and pointed. However, differs by (1) being widespread; (2) apex of penis rounded rather than bilobed; (3) cerci often shorter than paraprocts, rarely longer, not expanded distally, with no or only slight apical notch.
