Pararticerus ruthae sp. n.

Figs 28–30 , 39

Etymology: Named after Ruth Müller, curator of Coleoptera at the Transvaal Museum, Pretoria, who was always ready to help me with many aspects of this study.

Differential diagnosis: This species can be separated easily from P. latus by the presence of two larger spines on the mesofemora, by the apical spur of the mesotibiae being located very close to the apex, as well as by the different shape of the aedeagus.

Description: Body reddish brown, elytra and abdomen lighter, about 1.6 mm long and 0.75 mm wide, head about as long as wide and slightly shorter than pronotum, with roughly reticulate surface, tempora slightly convergent with few erect setae; terminal antennomere conical, about 3.6 times as long as wide as at apex, about 3.9 times as long as III; pronotum about 1.1 times as wide as long, with about 8 macrosetae on sides, longitudinal sulcus absent, median antebasal fovea present; abdomen shining, with minuscule, sparse setation; mesofemora ( Fig. 30 ) with two large, obtuse spines, inner one larger, mesotibia with apical spur located close to apex.
