Graycassis enfield , new species

Figures 566, 567 ; Map 68

TYPE: Male holotype taken in a pitfall trap at an elevation of 1130 m on Daisy Patch Fire Trail, 1.9 km S Enfield Road, Enfield State Forest , 318209S, 1518549E, New South Wales (Feb. 4–Apr. 9, 1993; M. Gray, G. Cassis), deposited in AMS ( KS37368 ) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males resemble those of G. barrington in the general shape of the me­ dian apophysis, but that apophysis is both shorter and wider posteriorly (fig. 566) than in G. barrington .

MALE: Total length 7.1. Coloration as in G. marengo . Leg spination: tibiae: III v2­2­ 2; IV r1­1­1; metatarsi IV p0­1­0. Retrolateral tibial apophysis entire, ledge­shaped (fig. 567); median apophysis long, gradually widened from base, distally produced (fig. 566).

FEMALE: Unknown.

VARIATION: The single male taken at Mummel Forest Road has the median apophysis distally larger, and bearing a relatively larger distally produced lobe. It could conceivably represent a closely related species, but much larger samples would be needed to test that hypothesis.
