Lampona chinghee , new species Figures 262–265 ; Map 31

TYPE: Female holotype taken in a Berlese sample of sieved rainforest litter from an elevation of 720 m on Mount Chinghee , 12 km S Rathdowney, 288199S, 1528589E, Queensland (Dec. 17, 1982; G. Monteith, D. Yeates, G. Thompson), deposited in QMB ( S28077 ) .

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

DIAGNOSIS: This species can be distinguished by the almost triangular retrolateral tibial apophysis and narrow embolus of males (figs. 262, 263) and the large, wide epigynal midpiece and large posterior portions of the spermathecae of females (figs. 264, 265).

MALE: Total length 5.7. Abdominal dorsum with white spots united into lateral longitudinal stripes, median dark stripe interrupted by chevrons; anterior femora darkened, posterior femora with subdistal, posterior tibiae with proximal and distal dark rings. Palpal femur darkened throughout most of its length, otherwise unmodified; retrolateral tibial apophysis triangular, setose (fig. 263); tegulum globose, extending to almost half length of tibia; embolus relatively narrow, even at base (fig. 262).

FEMALE: Total length 7.2. Coloration as in male except white stripes much less extensive. Epigynum with wide, tongue­shaped midpiece (fig. 264); spermathecae tripartite, posterior portions largest (fig. 265).

Lampona molloy , new species

Figures 266–269 ; Map 31

TYPE: Female holotype from Molloy Road, Mount Molloy , 168419S, 1458209E, Queensland (Feb. 18, 1972; N. Coleman), deposited in QMB ( S25982 ) .

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

DIAGNOSIS: The sexes have not been collected together, but the male here associated matches the females well in abdominal color pattern. Males can easily be recognized by the long, narrow retrolateral tibial apophysis (fig. 267), females by the elongate spermathecae with small posterior portions (fig. 269).

MALE: Total length 4.3. Abdominal dorsum with anterior and median pairs of white spots united into lateral longitudinal stripes; anterior femora darkened, posterior femora with subdistal, posterior tibiae with proximal and distal dark rings. Palpal femur with low, setose ventral protuberance at base; retrolateral tibial apophysis with long, needleshaped dorsal spur (fig. 267); tegulum moderately expanded, probably reaching to about one­third of tibial length (uncertain, as only available palp is expanded); embolar tip recessed behind conductor (fig. 266).

FEMALE: Total length 7.3. Coloration as in male except abdominal stripes wider. Epigynum with relatively wide, short, midpiece reaching to only half of spermathecal length (fig. 268); spermathecae tripartite but posterior portions very small (fig. 269).
