Gray, G. Cassis, AM KS40687 .

Diagnosis. Males differ from those of P. venusta in the absence of a medial constriction in the scute, no indication of sheen or iridescence on the dorsal scute or carapace and a semicircular subtegular excavation retrolaterally and from those of P. qunats sp. nov. in having the prolateral edge of the distal cymbium tumid ( Fig. 106a, c ) rather than the narrow. Females unknown.

Etymology. A noun in apposition from the type locality.
