Trachycosmus turramurra , new species Figures 297–300 ; Map 23

TYPE: Female holotype from Turramurra , 33 ° 44 ̍ S, 151 ° 08 ̍ E, New South Wales (June 12, 1979; Williams), deposited in AMS (KS3059) .

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

DIAGNOSIS: This appears to be the southern sister species of T. allyn , although they may not be completely allopatric. Males of this species have a longer embolus and a longer retrolateral prong on the median apophysis (fig. 297), as well as a pronounced distal rim on the ventral surface of the palpal femur; females have a shallow, triangular epigynal atrium, most of which is occupied by a wide septum (fig. 299) and much narrower median epigynal ducts (fig. 300).

MALE: Total length 5.3. Coloration as in T. sculptilis except no leg segments darkened. Legs spineless. Palpal femur with distinct ventral enlargement at distal end; retrolateral tibial apophysis expanded, ridge­shaped (fig. 298); embolus relatively long, extending far proximal of palpal bulb (fig. 297).

FEMALE: Total length 6.2. Coloration as in male. Legs spineless. Epigynum with narrow, anteriorly narrowed atrium mostly filled by median septum that grades into atrium posteriorly, in advance of two procurved posterior margins (fig. 299); median epigynal ducts narrow (fig. 300).
