Ozcopa View in CoL gen. nov.

Diagnosis. Males differs from those of Copa kabana sp. nov. in the presence of a paracymbial process and spine and females in the large diagonally oval copulatory fossae. Males and females differ from those of Echinax Deeleman-Reinhold, 2001 by the absence of the long patellar spines and the presence of a paracymbial process and spine.

Etymology. An arbitrary combination of letters based on Copa ; the gender is that of Copa .

Type species: Ozcopa colloffi View in CoL sp. nov.

Description. Pallid castianeirines with dark pattern medially on carapace and abdomen. Lateral profile of carapace ( Fig. 2e View FIGURE 2 ): high but more or less flat or slightly arched for its length; marginally highest point behind fovea at shallowly sloping posterior declivity; eyes set behind clypeus edge. Retrolateral face of large chelicerae smooth ( Fig. 2e View FIGURE 2 ). Eight eyes in two rows, front row slightly recurved, back row slightly procurved ( Fig. 16f View FIGURE 16 ). AME clearly the largest, followed equally by PLE and PME. Group occupies 0.6 of head width. Chelicerae well developed; two teeth on retromargin; three on promargin; fang shield and thickened setae in females absent to triangular with fringe of long distally serrate hairs; fang shield small to absent in males. Scopula absent in males, weak on metatarsi and tarsi I and II of females; preening combs absent. Spines similar on all legs. Tibiae I and II with 3–4 pairs of long spines ventrally, metatarsi I and II with two ventral pairs. Feathery hairs on legs. Trochanter IV with shallow but distinct notch; shallower on I–III. Legs I, II and IV of similar thickness, leg III thinner; femur IV distally unmodified. Male palp: paracymbial spine set well forward of basal edge ( Fig. 93e, f View FIGURE 93 ); embolus a simple short spiral ( O. zborowskii sp. nov., O. mcdonaldi sp. nov., Figs 94a View FIGURE 94 , 96b View FIGURE 96 ) or with complex tip ( O. colloffi sp. nov., O. margotanderseni sp. nov., and O. monteithi sp. nov., Figs 93a–f View FIGURE 93 , 94c–e View FIGURE 94 , 97a–c View FIGURE 97 ); basal cymbium with long edge evident proximal to bulb ( Figs 93e, f View FIGURE 93 , 94c View FIGURE 94 , 97a View FIGURE 97 ). Abdomen with small triangular dorsal scute in males ( Fig. 92a–c View FIGURE 92 ), ventral scute present in O. colloffi sp. nov. and O. zborowskii sp. nov.) or absent. Genital plate sclerotised, forming wide ring around anterior abdomen to pedicel; tracheal spiracle with short sclerotised edge, no plate. Epigyne externally two large transverse oval fossae ( Figs 93g View FIGURE 93 , 95d View FIGURE 95 ), anteriorly a rounded edge; posteriorly a hooded ridge; fossae pass centrally to two large domed receptacula, folding back to form two divergent lobes from which fertilisation duct arises ( Figs 93h View FIGURE 93 , 95e View FIGURE 95 ).

Distribution and Habitat. Known only from rainforests of north-eastern Queensland focussed on the Wet Tropics World Heritage area.

Species included. Ozcopa chiunei sp. nov., O. colloffi sp. nov., O. margotanderseni sp. nov., O. monteithi sp. nov., O. mcdonaldi sp. nov., and O. zborowskii sp. nov.

Remarks. The embolic tip in three species of Ozcopa gen. nov. is not simple but quite complex ( Figs 93a–f View FIGURE 93 , 94c–e View FIGURE 94 , 97a–c View FIGURE 97 ), which adds a refinement to the concept of the castianeirine bulb that is typically pear-shaped.
