Yan, Chuncai, Saether, Ole A., Jin, Zhaohui & Wang, Xinhua, 2008, Three new species of the Harnischia complex from the Sino-Indian Region, with a review of Demicryptochironomus Lenz (Diptera: Chironomidae), Zootaxa 1968, pp. 1-22 : 9-10

Demicryptochironomus (Demicryptochironomus) inawabeceus (Sasa, Kitami et Suzuki) comb. n.

( Figs 16–18)

Cryptotendipes inawabeceus Sasa, Kitami et Suzuki, 1999: 9 ; Yan et al. (2005: 27).

Material examined. Holotype male ( NSM No. 389: 54), JAPAN: Fukishima Prefecture , Inawashiro Lake, 20.viii.1999, light trap and sweep net, K. Kitami.

Diagnostic characters. The species is similar to Demicryptochironomus vulneratus (Zetterstedt) in having a digitiform superior volsella, but differs in having a bare inferior volsella.

Male ( Figs 16–18). As in Sasa et al. (1999: 9) with the following corrections and additions: AR 2.91. Brachiolum with 3 setae, R with 24 setae, R 1 with 22 setae, R 4+5 with 36 setae. Mid ta 1 with 3 sensilla chaetica. Tergite IX with 26 setae. Laterosternite IX with 4 setae. Anal tergite bands V-shaped. Phallapodeme 98 µm long. Transverse sternapodeme 35 µm long. Gonocoxite 150 µm long, inner margin with 6 strong setae. Gonostylus 190 µm long, swollen in basal 1/3, tapering towards apex, inner margin with12 setae. HR 0.79; HV 2.64.

Remarks. Yan et al. (2005) suggested that the species should be placed in Demicryptochironomus based on the original description and figures. After re-examining the holotype, we confirm this formally. The genus Cryptotendipes differs from Demicryptochironomus in having an inner expansion on the base of the gonostylus.

Distribution. The species is recorded from Japan.
