( Figs 27–30 View FIGURES 27 – 30 )

Type material: Holotype male, TANZANIA, Tanga region, West Usambara Mountains, Mazumbai, 26.xi.–4.xii.1990, ZMB's Tanzania Expedition, ( ZMUN). Paratypes: as for holotype except 1 male, 31.x.1990; 1 male, 31.x.–2.xi.1990; 1 male, 4.11.1990; 1 male, 12–20.xi.1990; 2 males, 29.xi.1990.

Etymology: Named after Gunnar Wang for all help and support during the present study.

Diagnostic characters: The male can be separated from all other species in the genus in having a simple, narrow, slightly curved gonostylus.
