Material examined.

Holotype male: AUSTRALIA: New South Wales: New England National Park [30°56'S, 152°46'E] (QM S108796), coll. G. Monteith, 2 November 1980.

Etymology.

The specific name is an adjective ( albimanus Latin = white-handed) and refers to the palps that are covered in long white setae.

Diagnosis.

Males of J. albimanus differ from congeners by the palpal femur, patella, tibia and cymbium covered with long white setae (Fig. 3C); patella I with a fringe of long and dark setae (Fig. 13D); embolic disc wider than long and very broad rim; embolus with pointed tip, closely accompanied by semicircular conductor (Fig. 3E, 12B arrow).
