Girault (1913a, p. 226), as Signiphora australica (original description).

Dahms (1983, p. 91): notes on type material.

Type material. Holotype male, QM Hy 773 (T773; T4412), under cracked resin and coverslip, along with a specimen of Aphelinoidea howardi Gir. Transcription of labels as in Dahms (1983): ‘From window of a workmen’s quarters. Sugar farm, Nelson [= Gordonvale], N.Q. XII.21.1911 ’, ‘ Signiphora australica Girault , ♂ Type, Hy/773 4412, 4412 ’, and on the reverse of the slide, ‘Queensland Museum. TYPE, Hy/773 S’. Dahms (1983) lists two other slides at the QM, one topotypical, with the date of 4 December 1911 (paratype, male) and the other without locality information, on the same slide as the type of C. australiensis orbiculatus . The original description refers only to the two males from Nelson (‘in xylol-balsam, December 4 and 21, 1911 ’) and indicates Hy 773 as the type. Dahms (1983) also states that T4412 was a duplicate QM accession number for this specimen and had been cancelled.

Description. Male. Length (pronotum to apex of epiproct): 0.6 mm. Body brown; metasoma and propodeum darker than head and mesosoma; antennae, genae and clypeus slightly lighter than surrounding areas. Head approximately round in frontal view, antennal scrobes evident, clava 7× as long as wide, 3 anelli (2:2:1), pedicel 2.5× as long as wide, scape 4× as long as wide, clava 2.5× length of scape. Many structures cannot be observed. Pronotum about 8× as wide as long. The other sclerites were crushed; margins are not discernible. The wings are not visible. Median propodeal sclerite seems to be coarsely reticulated like the remainder of the metasoma. Mt1 visibly bilobed.
