Spilomicrus coelopae (Early, 1978) comb. nov.
Paratypes 12 ♀♀, 17 ♂♂.
An additional male from the Otago peninsula labelled as a paratype is not a type; specimens from this locality are listed under “other material” and so are not types. All current Antarctopria species, A. coelopae, A. campbellana Yoshimoto, 1964, A. diomedeae Early, 1978, A. latigaster Brues in Tillyard, 1920 and A. rekohua Early, 1978 appear to belong to a derived species group of Spilomicrus showing pronounced wing reduction and the associated suite of characters that go with it. Extra setae on the gastral tergites are found on wing-reduced representatives of a number of other diapriid genera and is not considered here a character of generic value. Consequently, these five Antarctopria species are transferred to Spilomicrus (new combinations), and since Antarctopria latigaster is the type species of Antarctopria, this genus is now a synonym of Spilomicrus syn. nov.
