Morebilus tambo , new species Figures 391–394 ; Map 31

TYPE: Male holotype taken in rolled up tarp at Caldervale, Tambo , Bullrush Bore , 25 ° 06 ̍ S, 146 ° 50 ̍ E, Queensland (Oct. 16, 1990; P. Cause), deposited in QMB ( S18794 ) .

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

DIAGNOSIS: Males resemble those of M. diversus in having dorsally directed spines present on the retrolateral tibial apophysis (fig. 392), but can be distinguished by lacking a subdistal embolar expansion (fig. 391); females also resemble those of M. diversus in having a relatively long, narrow epigynal atrium (fig. 393), but have a longer atrium, not restricted to the anterior portion of the epigynum (fig. 393) and larger, basally narrower spermathecae (fig. 394).

MALE: Total length 10. Coloration as in M. graytown , except leg IV darkest. Leg spination: tibiae I, II v2­3­2; metatarsi II v2­1p­0. Retrolateral tibial apophysis short, with ex­ panded base bearing dorsally directed spines (fig. 392); embolus with truncated basal lobe and arched tip without subdistal expansion (fig. 391).

FEMALE: Total length 10. Coloration as in male. Leg spination: tibiae I v4­2­2; metatarsi II v2­1p­0. Epigynum with long, narrow atrium extending almost to posterior edge of structure (fig. 393); spermathecae anteriorly soft, inflated, with laterally directed heads (fig. 394).

OTHER MATERIAL EXAMINED: Queensland: Dargonelly Rock Holes, Mount Moffatt National Park , 25 ° 01 ̍ S, 147 ° 57 ̍ E, Sept. 20–27, 1986, open forest (M. Bennie, QMB S15955 ), 1♀ ; Kumbarilla , W Dalby, 27 ° 19 ̍ S, 150 ° 53 ̍ E, Nov. 1979 (T. Adams, QMB S28444 ), 1♀ .
