Agriocnemis canuango Dijkstra, 2015
Bog Wisp

Type locality: Negage, Canuango River, Angola

Diagnosis

Male is unique among African Agriocnemis species by the (1) pronotal hindlobe that is entire and extended laterally and folded upwards to form a pair of erect knobs, which are flattened with rounded tips and thus rather spoon-like; and the terminal abdominal structure with (2) the distal border of S10 extended dorso-medially into a rounded knob that is about half as long as the segment, somewhat like in A. ruberrima but much thicker; (3) the cerci that are almost as long as S10 and over twice as long as the paraprocts, appearing rather thick, down-turned and distally truncated in lateral view, although their inside is hollowed out and thus appears ear-like in dorsal view, with a tiny black tooth directed straight downwards at their extreme base; and (4) the paraprocts reduced and rounded, with a ventral black tooth positioned externally to the cercal tooth, but even smaller and placed even more basally and visible only caudally. Other notable features include (5) the small size, Hw 9.3-9.7 mm (n = 5); (6) the black labrum with a greenish white border; (7) all Pt pale brown with the anterior border about twice as long as the posterior; and (8) the distally orange to reddish abdomen from halfway S7, whether teneral or mature.
