Etymology. The name reflects the pattern of lateral lines found on the abdomen. To be treated as a Latin adjective.

Remarks. Commonly confused with Apricia longipalpis and A. jovialis in collections. The drawings of the male palp of A. jovialis in Davies & Żabka (1989) are of this species.

Diagnosis. The females ( Figs 171–174 , 178–180 ) can be separated from P. semiatra by the distal rather than lateral direction taken by the insemination ducts and the possession of large rather than small atria. It can be separated from P. albobarbata L. Koch by the larger fertilization ducts and the median rather than lateral guides. The males ( Figs 175–177 ) 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 and emboli.

Description. Male: Holotype. Cephalothorax ( Figs 167, 168 ) dark brown with scattered pennate white hairs over anterior dorsal surface. Surrounds of ALE, PME and PLE, black. Clypeus ( Figs 169, 170 ) narrow, with a thin fringe of dark hairs. Area immediately ventral to the clypeus and dorsal to the chelicerae bright white. Chelicerae straight, dark brown with a single small promarginal tooth and a small, unident retromarginal tooth. Endites, labium and sternum dark brown. Dorsal abdomen dark brown with a fine lacy pattern of black markings and a distinct pattern of bright yellow chevrons and lateral stripes. Spinnerets dark brown with yellow tips. Ventral abdomen black with four longitudinal rows of small yellow dots. L1 dark brown, except for patella, which is bright yellow and more robust and larger than other legs, without fringing. Remaining legs dark brown with bright yellow trochanters, coxae and tarsi. Palp ( Figs 175–177 ): Palps mid brown, cymbium with yellow tip. Tibia with thick apophysis tapering in the distal half to a twisted point. Tegulum bulging and twisted with a large posterior lobe. The sperm duct forms a half circle along the distal and anterior edge of the tegulum. The short embolus is placed on a large broad base on the distal edge of the tegulum. Dimensions: CL 2.79, EFL 1.05, CW 2.04, AEW 1.73, AMEW 1.18, PEW 1.67, AL 3.28, P1+T1 2.60, L1 5.82 (1.85 + 1.11 + 1.49 + 0.80 + 0.56), L2 4.33 (1.26 + 0.87 + 0.93 + 0.68 + 0.50), L3 4.15 (1.49 + 0.68 + 0.74 + 0.80 + 0.43), L4 5.02 (1.42 + 0.87 + 1.18 + 1.05 + 0.50).

Female: Paratype. As for male ( Figs 171 –174 ), except L1 not as strongly developed and the patella is dark brown rather than bright yellow. Epigyne ( Figs 178–180 ): consisting of a pair of posterior facing anterior atria with lightly sclerotised margins and a large median pocket opening from the epigastric fold. Copulatory openings near the atria but indistinct. Long insemination ducts pass posteriorly until joining the anterior edge of the spermathecae. No glands or diverticula seen. Spermathecae simple rounded chambers lying close to the epigastric fold on either side of the median pocket. Fertilization ducts on the median sides of the spermathecae. Dimensions: CL 3.10, EFL 1.18, CW 2.17, AEW 1.86, AMEW 1.24, PEW 1.80, AL 3.72, P1+T1 2.29, L1 5.51 (1.86 + 1.18 + 1.24 + 0.68 + 0.56), L2 4.52 (1.61 + 0.93 + 0.87 + 0.62 + 0.50), L3 4.09 (1.30 + 0.81 + 0.62 + 0.87 + 0.50), L4 5.63 (1.80 + 0.93 + 1.23 + 1.11 + 0.56).

Distribution and biology. Widespread across eastern Australia in a wide range of localities including reserves ( Fig. 181 ). As a consequence, likely IUCN Red List Category LC. Predicted to be found in the Australian Capital Territory, Victoria and, marginally, in South Australia but no specimens known from these states. Found in leaf litter, under bark and on foliage in habitats ranging from tropical and temperate forests to woodland. May be found in houses and gardens.
