Diagnosis
The male of P. morogorom gen. et sp. nov. can be recognized by the long, strongly tapered RTA. The female has a characteristic epigyne with central depression showing two dark areas, flanked by a kidneyshaped area on either side and the inverted funnel-shaped pattern in front.
Etymology
The species name is an arbitrary combination of letters forming a noun in apposition and containing ‘morogoro’, the region where the types were found.
