Pair of small processes (bp) with irregular inner margin, basal and ventral to median processes of antennae (Fig. 3B). Basal region of median process with 2-3 papillae (pa) on anterior margin (Fig. 3A, B), followed by 4-6 similar structures medianly at first bend. Anterior region of thumb (th) proximally folded (Fig. 4A), distal region slender, dorsally curved and apically pointed. Angle between proximal and distal region of anterior part of thumb approx. 170° (Fig. 3A). Angle between triangular spur (s) and anterior part of thumb approx. 90°. Finger (f) short (about one-half length of thumb), proximally broad and dorsally curved, with recurved acute apex (Figs 3A, 4A). Anterior margin of finger with long, convex, ridge-like tooth with anterior hook-like projection (Fig. 4A). Frontal appendage. Long (ratio to body length 0,39 : 1) and complex. Trunk (tr) dividing into two lateral branches (1LV/LV) and a third anterior branch (1A) about a one-quarter way along total length. Branch 1A bifurcate with each arm (a) tapered and about one-third length of frontal appendage. Long digitiform processes at base of trunk, along proximal half of ventral margin of each LV branch and just proximal to the division of 1A. Apically two LV branches and two arms narrow and with papillate processes (Fig. 3A). Cercopods. Moderate length (ratio to body length 0,21 : 1), straight, tapered and with plumose setae along both margins (Fig. 3C). Egg morphology Egg shell with large, simple, 4-6 sided fields, separated from neighbouring fields by thin, sharp ribs (Fig. 4B). Differential diagnosis Streptocephalus dendrophorus closely resembles the southern African S. clado- phorw* Barnard. The frontal appendage, cercopods and basal processes of the two. Fig. 4.
