Systematics: A re-examination of the specimens in Brain's collection identified by him as Chionaspis (Poliaspis) kiggelariae revealed that more than one species is involved. Two lots from Salix sp. are conspecific and form the basis for the identity of T. kiggelariae. The lot collected from Kiggelaria africana is conspecific with T. visci. Because the "holotype" of T. kiggelariae was selected by Brain from the willow specimens T. kiggelariae does not become a synonym of T. visci (Munting, 1967a).
Structure: Female scale 2.2 mm long, elongate, more or less parallel-sided, convex, usually straight, silky, white, with transverse ridges small, numerous, close together. 1st exuviae greyish or brownish; 2nd exuviae covered, brown. Male scale white, moderately elongate, usually with prominent median ridge and two lateral ones, which are especially conspicuous at posterior end. Exuviae pale yellow or almost colorless. Slide-mounted adult female 1.6 mm long. Median notch is wide, with 2 short plates and two short spines. L1 wider than long, uniformly rounded when not worn; L2 composed of two lobules, which may be somewhat rounded, but most often pointed (Brain, 1919).
