Female aptera
: Body, legs and antennae brown with antennal segments I–II almost yellow, tarsi and apex of tibiae scarcely paler than femora; major setae all pale.
Head longer than wide (
Fig. 27
); cheeks almost parallel, dorsal surface reticulate except in midline, mid-dorsal setae not elongate; eyes with about 3 facets dorsally and 2 ventrally; postocular setae short, broadly capitate. Antennae 7-segmented (
Fig. 22
), III short and broad with narrow pedicel and no sense cone, IV with 2 sense cones; segments IV–V dorsally with 2 transverse sculpture lines, VI with faint lines. Pronotum reticulate, with about three irregular rows of small tubercles along posterior margin; with 5 pairs of short, broadly capitate setae, notopleural sutures incomplete. Mesonotum reticulate, with one pair of small capitate lateral setae. Metanotum weakly reticulate, with about 30 bluntly pointed discal setae (
Fig. 42
). Prosternal basantra not developed; ferna transverse, not meeting medially; mesopresternum reduced to pair of very small lateral triangles, mesoeusternum anterior margin strongly eroded. Pelta sub-quadrate, reticulate with pair of campaniform sensilla (
Fig. 42
); tergites weakly reticulate with rows of small tubercles near posterior margins, with transverse row of bluntly pointed discal setae; II–VI with pair of short, asymmetrically capitate posteromarginal setae (
Fig. 42
), these setae longer on VII–VIII; setae S1 on IX capitate, longer than basal width of tube; S2 longer and finely acute.

Comments
. This is one of a group of three species from
Australia
in which the third antennal segment is unusually small and lacks any sense cones. It is distinguished from the other two by the absence of setae on the pelta, the presence of sculpture lines on the antennal segments, and the longer tube.
