While preparing a paper on the pselaphid genera of Australia, 
three groups of the Tyrini, subtribe Tyrina, were discovered which 
could not be placed within the current generic concepts of the Aus- 
tralian fauna. One of these groups appears to be congeneric with 
Tyrogetus Broun from New Zealand, while the other two represent 
undescribed genera. With the recognition of these taxa, the major 
generic components of the Tyrini appear to be described for 
Australia. 
All measurements are in millimeters. Slides of cleared and disar- 
ticulated specimens were used to determine the patterns of foveation 
of the genera. Holotypes are placed in the Australian National 
Insect Collection, Canberra, or in the National Museum of Victoria, 
Abbotsford. 
Tyrogetus Broun 
Tyrogetus Broun is represented by two species from New Zea- 
land, optandus Broun (figured by Jeannel 1962:448) and palpalis 
Broun. Three undescribed species from Tasmania are very close to 
these New Zealand species based on the suite of characters used to 
differentiate genera in the Tyrini. The two New Zealand species are 
easily separated by tergite I being five times the length of II, while 
the length of tergite I in the three Tasmanian species is about twice 
the length of II. The maxillary palpi of one Tasmanian species 
(occidentals n. sp.) is relatively robust, while the palpi of the New 
Zealand species are more elongate and narrow, and the palpi of the 
two other Tasmanian species are the longest and narrowest. The 
relative lengths of the tergites and form of the maxillary palpi are
