Types: Holotypes. Hoggicosa castanea , ♀ from Australia: no locality given, no date ( SAM NN015 ) . L. errans , ♀ from Australia: no locality given [ Hogg, 1905: ‘(without locality) sent from Adelaide’], no date ( SAM NN016 ) . L. skeeti , ♀ from South Australia: Wilson, Flinders Ranges , 31°60′S, 138°21′E, iv.1908 ( SAM NN019 ) ; L. perinflata , ♀ from South Australia: Whyte Yarcowie , 33°13′S, 138°53′E, i.1908 ( SAM NN017 ) .

Other material examined: 179 males, 134 females, and five juveniles from 232 records (Appendix S1).

Diagnosis: Hoggicosa castanea is most similar to H. brennani and H. forresti . The subterminal apophysis of H. castanea is very small and reduced ( Fig. 7A ), whereas it is much longer in H. brennani and H. forresti ( Figs 7C , 15B ). The pars pendula in H. castanea is opaque and joins at the embolus tip ( Fig. 7A ), whereas in H. brennani and H. forresti it is transparent and joins below the embolus tip ( Figs 7C , 15B ). Hoggicosa forresti may be distinguished by the presence of a black stripe on the dorsal abdomen, which is absent in both H. castanea and H. brennani . The venter of H. castanea , which is black ( Fig. 4B ), may also be used to distinguish it from H. brennani , in which it is pale with dark patches ( Fig. 4E ).

Description: Male: Based on SAM NN19314, Gluepot Station, Gluepot Homestead, 33°44′51′S, 140°01′07′E, South Australia ( SA). Dorsal shield of prosoma brown, with faint radial pattern, covered with black setae. Sternum and labium brown with scattered black setae. Chelicerae dark brown with white setae. Legs brown, but ventral side of femur paler. Opisthosoma dorsally greyish-black, with mottled pale and brown patches. Grey median longitudinal band in anterior
