Diagnosis. CL 2.78–4.00. Separated from all species by very strong reflexion of the distal conductor; and by the combination of the relatively broad width across the

ventral; d, lateral; e, posterior; f, dorsal—internal genitalia. Scale line 0.5 mm.

epigynal fossae compared to width of distal scape, and lobed appearance of the scape in posterior view.

Male (holotype). BL 5.75, CL 2.91 (2.91–3.92), CW 2.07, CapW 1.24, EGW 0.83, LL 0.45, LW 0.43, SL 1.45, SW 1.24. Legs: 1243 (I 13.89, II 12.29, III 9.56, IV 12.04); ratio tibia I length:CW = 1:0.59. Male palp: Fig. 11a,b. Cymbium with moderately developed retrolateral flange. Bulb longer than wide with the tegular lobe placed retrolaterally. Embolus origin retrolateral. Stem of T-shaped conductor probasally directed; anterior limb long, strongly expanded distally and fully reflexed; posterior limb placed probasally; tegular window placed retrobasally. RTA dorsad, largely visible in ventral view; RVTA relatively slender towards apex.

Female (KS58200). BL 6.84, CL 3.02 (2.78–4.00), CW 1.98, CapW 1.42, EGW 0.88, LL 0.49, LW 0.45, SL 1.46, SW 1.21. Standard colour pattern. Legs: 1423 (I 11.02, II 9.13, III 7.49, IV 9.40); ratio tibia I length:CW = 1:0.72. Epigynum: Fig.11c–e. Scape relatively long, mostly placed behind epigastric groove; sides weakly concave to parallel; end of scape truncate or slightly indented, and lobate in posterior view; ratio of width across anterior ends of epigynal fossae to scape width at narrowest point> 2.5:1; in side view distoventral scape weakly protuberant; epigynal fossae vertical. Internal genitalia: Fig. 11f.

Variation. Specimens from the Conondale Ranges are larger and the reflexed end of the conductor is broader than in other specimens.

Distribution. The Brisbane area of southeast Queensland and northwards to the Conondale Ranges.

Etymology. The specific name refers to the extended, reflexed tip of the conductor in the male palpus and means “banner” or “flag” (L.).
