Ulyxes calypso (Domrow, 1966) new combination

( Figs 6–9 , 58 )

Haemolaelaps calypso Domrow, 1966:173 .

Remarks. Males are unknown. Nesting material from 29 nestboxes used by Petaurus breviceps or P. norfolcensis in Victoria and SE Queensland were extracted and four nests were found to contain female U. calypso but no males were found. Based mainly on its small, weakly-dentate chelicerae this species can be assumed to be parasitic ( Table 3 ). Its strong, long sternal setae and thickened coxal setae are likely to be adaptations for resisting grooming while in its hosts’ fur.
