( Figs 25–27 ) Cryptotendipes oyabeprimus Sasa, Kawai et Ueno, 1988: 32 ; Sasa, Kitami and Suzuki (2002: 5) ; Yan et al . (2005: 27) ; Makarchenko et al . (2005: 409) . Material examined. Holotype male ( NSM No. 136: 55), JAPAN : Toyama Prefecture , Oyabe River , 19.viii.1987 , sweep net . Diagnostic characters. The species can be distinguished from other species of the genus by the rod-like superior volsella lacking elongated projection or pits, anal point with pointed apex, and gonostylus curved in distal 1/3. FIGURES 25–27. Demicryptochironomus (Irmakia) oyabeprimus ( Sasa, Kawai et Ueno, 1988 ) , holotype male. 25 —wing; 26 —hypopygium, dorsal view; 27 —hypopygium, ventral view. Male ( Figs 25–27 ). As in Sasa et al . (1988: 32) with the following additions: Brachiolum with 3 setae, R with 23 setae, R 1 with 17 setae, R 4+5 with 23 setae. Midleg without sensilla chaetica. Tergite IX with 18 setae. Laterosternite IX with 7 setae. Phallapodeme 85 m long. Transverse sternapodeme 37 m long. Superior volsella swollen distally. Gonocoxite 100 m long, inner margin with 6 strong setae. Gonostylus 185 m long, curved in distal 1/3, inner margin with 12 setae. HR 0.54; HV 1.75. Remarks. Yan et al . (2005) suggested that the species should be placed in Demicryptochironomus based on the original description and figures. Re-examination of the holotype show that the species belong in the subgenus Irmakia , as it has Y-shaped anal tergite bands, a nearly parallel-sided gonostylus, rod-like superior volsella, and lacks inferior volsella. Cryptotendipes species have an inner expansion at the base of the gonostylus. Distribution. The species is recorded from Japan and the Russian Far East.
