Gray & Smith: Therlinya   , a new genus of stiphidiid spiders 305

ventral; d, lateral; e, posterior; f, dorsal—internal genitalia. Scale lines 0.5 mm: vertical, a,b; horizontal, c–f.

Diagnosis. CL 2.78–3.80. Separated from all species by the combination of relatively narrow width across the anterior fossae compared to width of distal scape, and rounded appearance of scape end in posterior view; from all species except T. ballata   and T. vexillum   by the retrobasal position of the tegular window; and from these species by the lack of a marked reflexion of the distal conductor.

Male (holotype). BL 6.86, CL 3.31 (2.78–3.39), CW 2.24, CapW 1.43, EGW 0.96, LL 0.51, LW 0.43, SL 1.55, SW 1.39. Legs: 1243 (I 15.18, II 13.27, III 10.78, IV 13.22); ratio tibia I length:CW = 1:0.58. Male palp: Fig. 9a,b. Cymbium with moderately developed retrolateral flange. Bulb longer than wide with tegular lobe placed retrolaterally. Embolus origin retrolateral. Stem of T-shaped conductor probasally directed; anterior limb long, apically relatively narrow with slight reflexion only; posterior limb placed basally; tegular window small, placed retrolaterally. RTA dorsad, largely visible in ventral view; RVTA relatively slender.

Female (KS58449). BL 7.55, CL 3.47 (3.47–3.80), CW 2.24, CapW 1.67, EGW 1.00, LL 0.51, LW 0.49, SL 1.57, SW 1.41. Standard colour pattern. Legs: 1423 (I 12.12, II 10.08, III 8.41, IV 10.37); ratio tibia I length:CW = 1:0.72. Epigynum: Fig. 9c–e. Scape of medium length, mostly placed behind epigastric groove; ratio width across anterior fossae to scape width at narrowest <2.5:1; sides of scape slightly to deeply concave; end of scape truncate to convex; rounded and sometimes bulbous in posterior view; distoventral scape protuberant in side view; epigynal fossae vertical. Internal genitalia: Fig. 9f.

Distribution. Border Ranges area of northeastern New South Wales and southeastern Queensland.

Variation. Epigynal scapes vary from the example figured with highly concave sides ( Fig. 9c) to a shape very similar to T. vexillum   ( Fig. 11c). The combination of characters given in the diagnosis will suffice to separate these species.

Etymology. The specific name is taken from the type locality which is an Aboriginal word meaning “a pine ridge”.
