Diagnosis
The males of P. aleykyela gen. et sp. nov. are easily recognized by large palpal patella and the conspicuous basal extension of the tegulum.
Etymology
The species name is an arbitrary combination of letters forming a noun in apposition and containing ‘Kyela’, the name of the type locality.
