Diagnosis

Male is similar to S. tenuis 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; at least hind tibiae usually white anteriorly; (c) 3-5 cross-veins between R2 and R3 before origin of IR2; (d) S2 without lateral black lines or these abbreviated before apex; (e) red confined to dorsum of S3-10, venter black; (f) paraprocts black, about ½ as long as cerci. However, differs by (1) being less widespread, limited to W Tanzania; (2) tibiae all black rather than anteriorly white; (3) S2 with lateral black lines. [Adapted from Dijkstra & Clausnitzer 2014]
