Fovea width 0.83, straight, deep, edges recurved, posterior wall centrally divided by pitted intrusion. Eyes . Raised on mound. Posterior half of ocular area adjacent to eyes black. Widths of anterior and posterior rows c. equal, 0.90 & 0.89 respectively. Eye group length 0.58, width/length ratio 1.55. Line joining posterior edges of ALE bisects AME.

Cymbium with c. 7(8) large and 7(8) smaller attenuate spines projecting forward from anterior half of d surface. RTA covered with short pointed d spines which continue around and onto rv edge of tibial excavation; c. midway on rv edge spines become longer and continue to end of straight horizontal DTA forming an extended brush. TEM prominent, pallid, adjacent to RTA, TET on pl surface. Bulb . ( Fig. 18B,C ) Embolic rl flange with c. 7 folds, margin distally sharply convexly curved under embolus as if twisted. Embolus straight, apophysis absent. Scopula . Complete on tarsi I, weak and complete on tarsi II, weak & incomplete on metatarsi I and II, absent on legs III and IV. Trichobothria . Palp: tarsi 7, tibia pd 4, rd 5. Leg I: tarsi 10, metatarsi 9, tibia pd 6, rd 6. Leg II: tarsi 9, metatarsi 9, tibia pd 5, rd 5. Leg III: tarsi 9, metatarsi 6, tibia pd 5, rd 5.

Dorsum with c. 27 long brown bristles in a broad median band; smaller bristles evenly scattered with underlying small bristles and hairs. Venter with cover of small bristles. Etymology . The species is named in recognition of arachnologist, Dr Barbara Baehr, at the Queensland Museum, Brisbane, Australia . Distribution and natural history ( Fig. 24D ). This spider is known only from the Chichester and Bulga State Forests, localities c. 90 km apart. The burrow is unknown.
