Pseudagrion (A) inconspicuum Ris, 1931
Little Sprite

Type locality: St. Amaro, Angola

Diagnosis

Male is similar to P. vumbaense and P. munte by (a) local in highlands; (b) size, withHw 16-20 mm; (c) Abd usually pruinose, as are often head and/or thorax Frons often pruinose; (d) cerci long, at least 1.5x as long as paraprocts, lower branch (usually) distinctly longer than upper, gap usually prominent, flange absent, small and/or more parallel to axis; (e) cerci without separate internal tooth near base. However, differs by (1) more widespread and ranging from Katanga and N Zambia to S Malawi and Angola; (2) labrum all pale blue, rather than green and black at base; (3) blue on genae usually extends somewhat onto frons posterior to postclypeus; (4) cerci with flange on lower branch obtuse at basal end (dorsal view).
