Figs 28, 40

Diagnosis

The male of Andromma juakalyi sp. nov. is small, pale and characterized by the details of the tibial apophyses: the RTA is broad at the base, pointing forward and tapered towards the thin bifid tip; the VTA is T-shaped in lateral view and axe-shaped in ventral view.

Etymology

The species name is a patronym in honour of Jean-Louis Juakaly, who collected the type specimen. He introduced arachnology at the university of Kisangani and is the first arachnologist of D.R. Congo.
