Stenocypha tenuis (Longfield, 1936)
Slender Jewel

Synonyms:

  • scientific: Chlorocypha tenuis; C. basilewskyi Fraser, 1955; C. jacksoni Pinhey, 1952 ssp. basilewskyi

Type locality: Kibale Forest, Toro District, Uganda

Diagnosis

Male is similar to S. hasta by (a) head with scattered yellowish spots, including bar on occiput; (b) markings of thorax broken up into more or less parallel stripes and blotches; (c) 3-5 cross-veins between R2 and R3 before origin of IR2; (d) at least hind tibiae usually white anteriorly; (e) S2 without lateral black lines or these abbreviated before apex; (f) red confined to dorsum of S3-10, venter black; (g) paraprocts black, about ½ as long as cerci. However, difers by (1) occurring from Burundi to Kenya; (2) at least hind tibiae anteriorly white, rather than all black; (3) S2 often without rather than with lateral black lines.
