Ozarchaea harveyi Rix, 2006: 229 , figs 10, 73–76, 115, 127.

Material examined. AUSTRALIA: Western Australia: 1 female, Huntly Mine, 5 km E. of Banksiadale Dam, 32°39’S, 116°05’E, tree trap on bark, 30 April-2 June 2005, A. Peck ( WAM T63656); 1 female, same data except 13 July-24 August 2005 ( WAM T64252); 1 female, same data except 25 August-6 October 2005 ( WAM T66535 ); 1 male, same data except 2 June–14 July 2005 ( WAM T64113); 1 male, same data ( WAM T63897).

Description of spinnerets. Female (spinnerets): Anterior lateral spinnerets (ALS) with two major ampullate (MAP) gland spigots, tartipore and separate, weakly demarcated field of five piriform (PI) gland spigots with reduced bases ( Figs 12–13 ). Posterior median spinnerets (PMS) with cylindrical (CY) gland spigot and two adjacent, posterior spigots, coded here as an aciniform (AC) gland spigot and slightly larger minor ampullate (mAP) gland spigot ( Figs 14–15 ); posterior mAP gland spigot nubbin and tartipore absent. Posterior lateral spinnerets (PLS) with two CY gland spigots separated by two AC gland spigots ( Figs 16–17 ); basal CY gland spigot with enlarged base; triad absent.

Male (spinnerets): As for female except without CY gland spigots on PMS and PLS ( Figs 18–21 ).
