Pungalina semiatra ( L. Koch, 1879) comb. nov.

Figs 182–198

Icius semiater L. Koch, 1879 . 1133, pl. 98, fig. 6.

Clynotis semiater — Simon 1901: 611; Żabka 1987: 442, figs 11–13 (redescription).

Type material. Syntype: Drawings provided by M. Żabka: Rockhampton, 150.52°E, 23.37°S ( ZMUH 16533).

Remarks. The syntypes are part of the collection in ZMUH and can no longer be borrowed, making work on this very extensive collection of Australian types difficult for Australian workers. Fortunately, Prof. M. Żabka has seen and drawn one of the male syntypes and kindly made his original illustrations available ( Żabka 1987).

Diagnosis. The females ( Figs 186–189 , 195–197 ) can be separated from P. albobarbata L. Koch and P. plurilineata sp. nov. by the lateral rather than distal direction taken by the insemination ducts, the very small atria and the absence of obvious fertilization ducts. The males ( Figs 182–185 , 190–194 ) can be separated from the other two species by the shapes and sizes of the proximal lobes on the tegula and the different shapes of the tibial apophyses.

Description. Male: Cephalothorax ( Figs 182, 183 ) orange/brown with scattered brown hairs over anterior surface. Surrounds of ALE, PME and PLE, black with scattered brown hairs. Lighter coloured striae highlighted by scattered white hairs on the steep posterior wall. Clypeus ( Figs 184, 185 ) orange/brown, narrow, with a thick fringe of white hairs. Chelicerae brown, straight. Two promarginal teeth and one medium fissident retromarginal tooth. Endites. labium and sternum brown. Abdomen ovate, tapering to the rear. Dorsal abdomen cream with medium brown distinct pattern ( Fig. 182 ). Spinnerets brown grading to cream. Ventral abdomen mid brown with four longitudinal rows of cream spots. L1 orange brown with cream patella and tarsus. Remaining legs cream with brown femurs. Palp ( Figs 190–194 ): long, brown, tibia with single tapering apophysis. Tegulum brown, relatively broad with a proximal lobe tapering to the posterior side and a small lobe midway along the anterior side. Embolus arises from a tapering base and curves in an anticlockwise direction. Dimensions: General: CL 1.89, EFL 0.80, CW 1.55, AEW 1.05, AMEW 0.87, PEW 1.39, AL 2.41, P1+T1 1.55: L1 3.59 (1.11 + 0.74 + 0.80 + 0.50 + 0.43), L2 3.41 (0.93 + 0.74 + 0.87 + 0.50 + 0.37), L3 2.60 (0.87 + 0.37 + 0.43 + 0.56 + 0.37), L4 3.22 (1.05 + 0.43 + 0.68 + 0.62 + 0.43).

Female: As for the male ( Figs 186–189 ). Epigyne ( Figs 195–197 ): consisting of a pair of small round atrium placed laterally. Insemination ducts move laterally towards the midline and then posteriorly grading into the anterior edge of the spermatheca. Fertilization ducts small and indistinct in the median wall of the spermathecae. Dimensions: CL 2.35, EFL 0.96, CW 1.86, AEW 1.49, AMEW 0.99, PEW 1.61, AL 2.85, P1+T1 1.61: L1 3.56 (1.30 + 0.50 + 0.80 + 0.53 + 0.43), L2 3.41 (1.11 + 0.68 + 0.68 + 0.50 + 0.43), L3 3.50 (1.05 + 0.59 + 0.56 + 0.80 + 0.50), L4 4.15 (1.36 + 0.62 + 0.87 + 0.80 + 0.50).

Distribution and biology. Widespread across the wetter parts of Australia of temperate eastern Australia in a range of habitats including reserves ( Fig. 198 ). As a consequence, likely IUCN Red List Category is LC. Found in litter.
