Girault (1915, p. 68), as Signiphora australiensis orbiculata   (original description). Dahms (1983, p. 92, 111): notes on type material.

Type material. Holotype male, QM Hy 2965 (T2965). The label, in Girault’s handwriting, indicates: ‘Type | Hy/2965 | A.A. Girault || Signiphora   | australica Gir.   || (red label) 4409 | Signiphora   | australiensis | orbiculata | Gir. ♀ ’. The description indicates the locality as Gordonvale (Cairns), North Queensland, but this locality information is not provided in the slide labels. Dahms (1983, p. 92) describes the slide which contains the holotype as ‘slide #3’ in his discussion of C. australicus   : ‘2 coverslip fragments; the one closest to “ TYPE ” label contains ♀ Signiphora australiensis orbiculata Girault   ; the other fragment contains a ♀ Signiphora australica   , head, wings and some legs separated’. The female indication in the label is a lapsus (holotype is a male). Dahms (1983) states that T 4409 is the QM number for the holotype.  

Description. Male. Length (pronotum to apex of epiproct): 2.2 mm. Body brown; legs slightly lighter, tarsi of mid leg and hind leg white, and apical tarsomere of hind leg tan. Fore wings infuscated, interrupted by a median hyaline band; the anterior part of the infuscation extending from the base to the stigmal vein is slightly darker than the posterior. Head (crushed in the specimen; some structures not clearly visible), scape wide (approximately 3× as long as wide, pedicel 2× as long as wide, anelli not visible, clava fairly short and wide (4× as long as wide). Mesoscutum about 2× as long as scutellum, with 12 setae: 8 setae in posterior margin of scutellum plus 1 on top of each axilla. Mesotibia ½ length of metatibia, mesobasitarsus about ½ length of mesotibia, mesotibial spur slightly shorter than basitarsus, with 5 teeth. Mesofemur with 3 spines. Fore wings 3× as long as wide, marginal setae about 1/3 of maximum wing width, 1 seta in submarginal vein. Hind wing 4× as long as wide, marginal fringe about ½ width of wing, 1 seta in marginal vein. Mt1 bilobed, with a transverse area separating the two lobes.

Remarks. This name was made available at the subspecies level. Girault (1915) defined this subspecies based on differences of the wing infuscation. The distal portion of the wing is faintly infuscated as in C. australiensis australiensis   .
