Parachironomus kisobilobalis Sasa & Kondo nomen dubium

Parachironomus kisobilobalis Sasa & Kondo, 1994: 129. - Sasa and Kikuchi (1995: 102); Sasa (1998: 30); Sæther et al. (2000: 190).

Material examined.

JAPAN: Holotype of Parachironomus kisobilobalis Sasa & Kondo, 1994 (No. A 224: 49), male, Aichi Prefecture, Kiso River in dammed-up middle reach near Nagoya City, "emerged from a sample", 26. ii. 1992.

Remarks.

We have examined the holotype, but it was lacking the thorax, head except for antenna, tarsi of front legs, and half of the hypopygium. As the preserved parts do not suffice for placement of the species, we treat Parachironomus kisobilobalis as a nomen dubium. In any case, the original description calling the superior volsella "rod-like, with one apical seta and 4 short setae along inner margin" and the inferior volsella "semicircular, with 4 short marginal setae" (Sasa and Kondo 1994: 129; see also Figs 5 i– 5m) rules out that the species belongs to Parachironomus .

Distribution.

The species has been recorded only from the type in a Palaearctic part of Japan.
