Diagnosis

The male of P. sinis gen. et sp. nov. is easily recognized by the characters of the palp: the very simple RTA, which is a tiny protrusion, the short sharp, embolus and whitish setae on legs and abdomen.

Etymology

The species name is an arbitrary combination of letters forming a noun in apposition and containing ‘sin’ (Spanish for ‘without’) referring to the virtual absence of an RTA.
