Streptocephalus bidentatus Hamer & Appleton, 1993
Material examined. UG 179 Pongolo, South Africa
8d'd'14.8 (13.3-15.5) mm, 5W 16.4 (14.4-17.5) mm.
Remarks. Contrary to what was indicated by Hamer
& Appleton (1993), this material, like the specimens
of S. vitreus (Brauer), had a pair of conical protuberances, dorsomedially located on the posterior border
of the telson, in both sexes. Given that the antennal
morphology in S. bidentatus and S. vitreus is virtually the same, the only useful feature to distinguish
these species from each other is the morphology of the
cercopods, which are long and spinose distally in S.
bidentatus, while they are shorter and setose along the
inner and lateral borders in S. vitreus.
