Demicryptochironomus (Demicryptochironomus) harunasecundus (Sasa) View in CoL comb. n.
( Figs 13–15)
Parachironomus harunasecundus Sasa, 1996: 95 View in CoL .
Material examined. Holotype male ( NSM No. 291: 11), JAPAN: Gunma Prefecture, Haruna Lake , 25.ix.1994, light trap, M. Sasa.
Diagnostic characters. The species closely resembles Demicryptochironomus ginzancedeus Sasa et Suzuki in the shape of the superior volsella. It differs in having a bare inferior volsella with lateral projection with single apical seta.
Male ( Figs 13–15). As in Sasa (1996: 95) with the following corrections and additions: R with 24 setae, R 1 with 20 setae, R 4+5 with 32 setae. Midleg without sensilla chaetica. Tergite IX with 35 setae. Laterosternite IX with 4 setae. Anal tergite bands V-shaped. Phallapodeme 90 µm long. Transverse sternapodeme 30 µm long. Inferior volsella lacking microtrichia, with 1 apical seta, with lateral projection with 1 apical seta. Gonocoxite 138 µm long, inner margin with 6 strong setae. Gonostylus 188 µm long, swollen midially, tapering towards apex, inner margin with 13 setae. HR 0.73; HV 2.13.
Remarks. The holotype of Parachironomus harunasecundus Sasa do not have a distinct apical tooth and conspicuous setal pits on the superior volsella. The characters of the superior volsella, gonostylus and the anal tergite are consistent with the diagnosis of Demicryptochironomus . The species is thus transferred to Demicryptochironomus as a new combination.
Distribution. The species is recorded from Japan.
