One female deposited in ANIC - Australian National Insect Collection, CSIRO, Canberra.
Female macroptera.
Body yellowish brown (
Fig. 1
), fore legs yellow, tarsi yellow, tibiae brown, yellow in apical half and basally, femora brown in basal half, rest yellow; antennal segments
I-III
golden yellow,
IV-V
yellow with shaded brown distally,
VI-VIII
dark brown; fore wing uniformly shaded with apex pale, clavus brown; first vein with 11 setae, not uniformly arranged; second vein with 6 setae. Antennae 8-segmented; sutures complete and distinct between all segments;
III-IV
with thin, Y-shaped sense cones, the arms unusually thin and curving around the segment, narrow apex on IV shorter, wider, more abruptly constricted than III; outer sense cone on VI extending to midpoint of VIII (
Fig. 3
). Head wider than long; ocellar hump weakly developed, ocelli visible; major setae rudimentary; eyes not bulged, covering lateral side almost completely; genae much reduced, without protruding transparent fringe (
Fig. 2
). Pronotum reticulate, raised sculpture on lateral margins; median area with transverse reticulations (
Fig. 2
). Mesonotum anterior margin shallowly notched, not reaching beyond anterior one third; 2 pairs of small setae, the inner pair anterior to the outer pair (
Fig. 4
). Metanotal median triangle weakly indicated; polygonally reticulate, extending beyond posterior margin, median setae anterior to campaniform sensilla (
Fig. 4
). Fore wing base humped, costal setae shorter than fringe; first vein with 7 basal setae, 2 at middle and 2 distally, thin and pointed; second vein with 6 setae, curved except last three; clavus with 4 veinal setae but no discal seta; posteromarginal cilia wavy (
Fig. 6
). Fore tibia with a spine at apex; hind tibia with a row of 11 conspicuous spines on inner side and two stout ones at apex; hind tarsi with a spine at median on inner side and two short, stout ones at apex. Abdominal tergite I reticulations extending beyond margin; median area of II with weak reticulations, laterally with wart-like tubercles; thick sublateral antecostal line on
III-VII
, laterally forming a posterior directed notch; VIII with complete posteromarginal comb of minute teeth; IX with campaniform sensilla; X asymmetric, median split complete, terminal setae almost half as long as the segment (
Fig. 5
). Sternites
II-VII
with 2 pairs of marginal setae on broad craspedum; antecostal lines on
III-VII
with median concave invagination. Ovipositor long, well developed, exceeding abdominal apex.
