Anal point narrow at base, with 5-13 setae in individual spots on tergite IX.  Superior volsella of the D-type, closest to e of Strenzke (1959), but tip may be more bent.  Inferior volsella with forked setae, reaching to about the midpoint of the gonostyle, which is only moderately swollen and narrows relatively sharply over posterior half.

Female (1 specimen, supplemented from Sasa 1978):
                                                                                                                                   Adult female of C. circumdatus from Australia. (from BOLD)
