Hypodacne LeConte 
Hypodacne LeConte, 1875: 170. Type species, by monotypy, H. punctata 
LeConte. 
Euxestus, of authors (not Wollaston). 
Sen Gupta and Crowson resurrected LeConte’s name for a group 
of species, usually included in Euxestus , which have simple tarsi, 
lacking the characteristic ventral lobe on the first tarsal segment. 
In addition to the North American H. punctata , several Australian 
and New Zealand species are included. 
Hypodacne punctata LeConte 
(Fig. 20) 
Hypodacne punctata LeConte, 1875: 171. Type locality: Eastern United 
States. Holoype, No. 6763 M.C.Z. 
This species is easily distinguished from other North American 
cerylonids by the highly convex and oval body, which is longer than 
1.5 mm., widely separated and posteriorly closed procoxal cavities, 
distinct frontoclypeal suture and characteristic antennal club, and 
the lack of pronotal antennal cavities, femoral lines on the abdomen, 
and crenulations on the last visible ventrite. The related Euxestus 
erithacus Chevrolat occurs in the Greater Antilles and might be 
found in southern Florida, but that species is smaller in size and 
bears a distinct ventral lobe on the first tarsal segment, a feature 
absent in Hypodacne. 
Distribution. Known from scattered localities throughout eastern 
North America, from southern Ontario to Florida and west to 
Kansas and Texas. 
Biology. According to Stephan (1968), this species occurs in the 
galleries of carpenter ants (Camponotus) in southern Ontario. Speci- 
mens were observed crawling on walls of carpenter ant galleries in 
oak, elm, and beech. The larva of H. punctata is unknown, but 
that of the Australian species, H. bivulneratus (Lea), was described 
by Sen Gupta and Crowson (1973: 381) from specimens collected 
in leaf litter and decayed wood. 
Anommatinae Ganglbauer 
This subfamily includes the two Palaearctic genera Abromus 
Reitter and Anommatus Wesmael, the latter of which has been 
introduced into North America. Ganglbauer (1899) originally con- 
sidered this tribe to be related to cerylonids, but Crowson (1955)
