Macropsalis chiltoni, nov. sp. 



This specimen from Stewart Island is the first of the genus which has 

 been recorded from New Zealand, the species hitherto described having 

 come from the mainland of Australia, while the New Zealand forms were 

 believed to have all fallen into the allied genus Pantopsalis, E. Sim.

 femoral joint of palpi brown with yellow bands, remainder of palpi pale 

 yellow. Abdomen grey in front, with two parallel black-brown stripes
