Coecopria may be compared with similar structures in Malvina 
Cameron (New Zealand) and Odontopria Kieffer (Oriental), but 
this is merely due to convergence. Austropria is superficially remi- 
niscent of Psilus Panzer (Galesus Haliday) but has a different struc- 
ture of the terminal segments of the metasoma. Austropria shows no’ 
ties to any of Australian genera ( ? Solenopsiella Dodd) but does to 
Neotropic Doliopria and particularly to Coecopria. The latter genus 
is apparently closest to Austropria , but is also close to Doliopria and 
(?) Mitropria (see the key below). Among the characters con- 
sidered to be common and typical for both Austropria and Coecopria 
the following should be emphasized : head heavily punctured, front 
margin of great tergite notched medially, antennae with 1 1 or less 
segments, abrupt 3-segmented antennal club, mandibles protruded to 
form an opisthognathous beak, high degree of apterism and reduction 
of mesosoma. 
Key to genera related to Austropria and Coecopria 
1 ) Head heavily thimble-like punctured, punctures rather large, 
deep and dense (cf. Malvina Cam. and Odontopria Kieff. ) .... 2 
— - Head with no special punctulation, smooth, shining, sometimes 
with minute teeth anteriorly 3 
2) Antenna 1 1 -segmented ; eyes well developed, ocelli present; great 
sternite with no fold basally; palpi 5, 2 Austropria gen.n. 
— Antenna 10 or 9-segmented; eyes reduced to one ommatidium 
point; ocelli absent; great sternite basally with a peculiar horse- 
shoe-shaped fold filled with pilosity, palpi 1, o 
Coecopria gen.n. 
3) Vertex with a few minute teeth; anterior margin of great tergite 
not notched medially; mandibles hypognathous, protruded down- 
wards to form a beak Mitropria Ogloblin 
— - Vertex unarmed; anterior margin of great tergite notched 
medially; mandibles normal and not protruded 
Doliopria Kieffer 
If compared with each other Austropria is, no doubt, more plesio- 
morphous and less specialized than Coecopria. Table I illustrates 
this development. 
Coecopria presents by itself a fine example of evolution within 
one genus. The most plesiomorphous is C. plaumanni (the type 
species). It has 10-segmented antenna, the propodeum clearly sepa- 
rated from thorax, a well developed suture between the prothorax 
and mesoscutum, 5-segmented tarsi and the fold on the great sternite
