Tinytrema bondi , new species Figures 151 , 165–168 ; Map 11

TYPE: Male holotype from Bondi State Forest , 37 ° 07 ̍ S, 149 ° 08 ̍ E, New South Wales (Nov. 28, 1980; G. Gowing), deposited in AMS (KS69129) .

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

DIAGNOSIS: Males can easily be recognized by the retrolaterally directed prong situated at about half the length of the retrolateral tibial apophysis (figs. 165, 166), females by the narrow, convoluted epigynal ducts (figs. 167, 168).

MALE: Total length 2.8. Carapace dark chestnut brown, abdominal dorsum dark gray with pair of transverse white marks at about half of length and third white mark above spinnerets, paired marks extending around sides to venter; anterior legs with coxae and trochanters light brown, femora and patellae dark brown, distal segments orange, posterior legs with coxae and trochanters white, remaining segments as in anterior legs. Leg spination typical for genus. Retrolateral tibial apophysis enormous, longer than tibia itself, basal portion directed dorsally, distal portion directed ventrally, bearing retrolateral prong at base (fig. 166), embolus situated medially, short, with curved tip (fig. 165).

FEMALE: Total length 3.5. Coloration as in male. Leg spination typical for genus. Epigynum with bipartite anterior margin (fig. 167), ducts narrow, convoluted, anterior portion c­shaped (fig. 168).

Tinytrema kangaroo , new species Figures 169–172

TYPES: Male holotype and female allotype taken under bark of Eucalyptus rubida at Kangaroo Ground, 37 ° 41 ̍ S, 145 ° 12 ̍ E, Victoria (winter 1974; J. Wainer), deposited in QMB ( S26726 ) .

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

DIAGNOSIS: Males resemble those of T. bondi but have subequal prongs on the retrolateral tibial apophysis (fig. 170) and a prolaterally much less protuberant tegulum (fig. 169); females also resemble those of T. bondi but have the epigynal ducts more widely separated (fig. 172).

MALE: Total length 2.4. Coloration as in T. bondi except white mark on abdominal dorsum above spinnerets much reduced. Leg spination: tibiae III, IV v1p­0­0. Retrolateral tibial apophysis directed dorsally, distally bifid, prongs subequal in size (fig. 170); tegulum not produced prolaterally, embolus situated medially (fig. 169).

FEMALE: Total length 3.3. Coloration and leg spination as in male. Epigynal ducts recurved, widely separated, especially anteriorly, where obliquely oriented (fig. 171, 172).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the type locality in Victoria.
