Tullbergia bisetosa Boerner, 1903
Figs. 1-8

This species has been reported from a number of collections in different subantarctic regions but no illustrations of it have been published.

I have recently identified specimens of T. bisetosa from collections made by Dr J. L. Gressitt and by K. Watson from Macquarie Island. The accompanying illustrations are from specimens collected by Dr Gressitt on the moss Azorella, at the north end of Macquarie. These specimens are mounted on slides and deposited as hypotypes in the B.P. Bishop Museum, Honolulu.

Notes: Upper surface of Ant IV with very long simple setae and fine curved sense rods one of which is much longer than the others (Fig. 1); lower surface with many short simple setae. S.O.Ant III has three guard setae on the main organ, not two as described by Boerner, and two at the third separate sense rod. Details of the PAO and genital apertures as shown in Figs. 4, 5, and 3 respectively.
