Agriocnemis forcipata Le Roi, 1915
Greater Pincer-tailed Wisp

Type locality: Bahr-el-Ghazal, Sudan

Diagnosis

Male is similar to A. victoria by (a) underside of head black, save pale border along eyes; (b) metapleural suture with thick black stripe; (c) cerci long, curved towards each other like forceps; (d) paraprocts much shorter than cerci. However, differs by (1) larger size, Hw 11.5-14 mm; (2) anterior hamule with large anterior point, which is about 1/3 of hamule’s length, and dense clump of thick bristles on its base (near S1); (3) lateral green on S7 extends onto dorsum medially, narrowing dorsal black line, although S7 is all red in immatures and may blacken completely with age; (4) cerci strongly curved, denticles on inner border rather evenly placed.
