Centrina dorrigo , new species Figures 458–461 ; Map 52

TYPE: Male holotype taken in pitfall trap in rainforest at an elevation of 800 m at ‘‘ The Glade,’’ Dorrigo , 308249S, 1528449E, New South Wales (Mar. 22–Nov. 12, 1980; G., S. Monteith), deposited in QMB ( S26845 ) .

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

DIAGNOSIS: Males and females have not been taken together, but are paired here because of their respective resemblances to C. keira . Males differ from those C. keira in having a straight retrolateral tibial apophysis (fig. 459) and larger embolar apophysis (fig. 458), females in having a more triangular epigynum (fig. 460).

MALE: Total length 6.7. Coloration as in C. keira except abdominal venter with only about three small sclerites in each paramedian row. Leg spination: femora: II p0­1­1; III p0­1­1, r0­1­1; IV r0­1­1; tibiae III, IV p0­1­1; metatarsi III, IV p0­1­1, v2­1p­1p, r0­1­1. Retrolateral tibial apophysis not bent, dorsoventrally flattened at tip (fig. 459); embolar apophysis large, protuberant, tegular apophysis with extremely narrow apical projection, median apophysis dorsoventrally flattened (fig. 458).

FEMALE: Total length 10.2. Coloration as in C. keira . Leg spination: femora: I, II p0­ 0­0; III, IV r0­0­0; tibiae: III p0­1­1, r0­1­1; IV p0­0­1; metatarsi III, IV p0­1­1, r0­1­1. Epigynum triangular, with deeply excavated posterolateral pockets (fig. 460); median ducts small, dwarfed by translucent extensions to pockets (fig. 461).

OTHER MATERIAL EXAMINED: New South Wales: Terrace Creek, near Jenolan, 338499S, 1508029E, Dec. 1979, under rocks (A. Austin, AMS KS10011), 2/.

DISTRIBUTION: Known only from New South Wales (map 52).
