Face, antennae, palps, brown. Frontal tubercles present. AR about 3.
Thorax green, stripes reddish brown with a dark spot at the posterior end of the lateral stripes.
Legs pale. Anterior basitarsus not bearded. Ant LR = 1.76-1.80. Hind LR = 0.; F/T = 0.
Wings pale, halteres greenish.
Abdomen dark, slightly paler at posterior of segments.
Male terminalia distinctive due to short hairy superior volsella, rather like that of Xenochironomus. This appendage appears to have an extensive membranous region which can fold rather differently during slide-mounting and so lead to quite variable appearance of the SVo. Anal point broad, also as in Xenochironomus; styles only slightly tapered at the ends.
Types: Holotype male: 4 km n. Fernvale (-27.43, 152.65), AQ.19.1, 8.vi.1968 (leg. Jon Martin) reared male with pupal and larval exuviae, slide mounted. Allotype female: same data as Holotype male, reared female with pupal and larval exuviae, slide mounted. Paratypes: reared adult males and females, larval bodies with chromosome spreads, all slide mounted.
Holotype male, allotype female and paratypes will be lodged in the Australian National Insect Collection.
