Chironomus kiiensis - incorrect synonymy by Hashimoto et al. 1981.
Note that the Australian specimens were raised from larvae in the laboratory at a temperature of 20C and so some measurements and ratios may be different from those of Tokunaga’s wild-caught adults.
Wings with dark spot over the crossvein and with obvious dark clouds and seams, particularly in cell R5. 17-22 setae in squamal fringe, 2 Scf on branchiolum. Haltere pale.
Wing length 2.44-2.82 (2.07-2.35) mm; width 0.60-0.68 (0.53-0.64) mm; VR 1.02-1.07 (1.04-1.09).
Face yellowish brown, antennae and palps brown. AR about 3.00-3.13 (2.82-2.94). Frontal tubercles quite large, about 15-56 µm long and 10-15 µm wide. 11-19 (16) clypeal setae.
Palps (micron): 45 (40): 48 (40): (136): 161 (136): 234 (200).Thorax yellowish green with brown stripes, lateral stripes darker along the medial edge, and ending in a darker spot; postnotum and sternopleuron brown.
Setae: acrostichals - 9-11; dorsocentrals - 9-11; prealar - 4-5; scutellar in two rows - 2-3 in anterior row, 6-9 in posterior row (total 8-12).
Legs yellow, femur with a dark band just before the knee; tarsal joints darkened. LR 1.61 (1.59-1.630 (1.78-1.94).
Leg lengths (microns) and proportions as follows:
AntTa5 about 0.26-0.30 (0.32) length of Ti. About 7 sensilla chaetica on midTa1, and perhaps 5 on hindTa1.
Abdomen brown, no obvious bands on the segments. 5-6 (14) setae on TIX, probably in a single clear area.
Superior volsella essentially an E-type, perhaps closest to fig. h of Strenzke 1959, but end more sharply curved.
Inferior volsella reaching about to end of the anal point with some setae branched, in Micronesian specimens, this is noted as being unequal.
Style abruptly narrowing at distal third.
