Palindroma obmoimiombo  gen. et sp. nov.

Figs 11View Fig. 11 A–E, 12View Fig. 12 A–D, 13 A–B, 16View Fig. 16


The male of P. obmoimiombo  gen. et sp. nov. is easily recognized by its colour, the inconspicuous cheliceral lamina and the characters of the palp: the unmodified patella, the presence of a dorsolateral tibial apophysis and a bifid RTA, the large subtegulum with ridges and posterior swelling and the thin embolus lying in a groove of the tegulum.


The species name is an arbitrary combination of letters forming a noun in apposition and containing ‘miombo’, the type of woodland in which the type material was collected.
