Tokunagaia subulata View in CoL new species
( Figs. 13–15 View FIGURES 13–18 )
Type material
Holotype male. CHINA: Jilin Province, Antu County, Changbai Mountain , (43°07’N, 128°54’E), 1700 m a.s.l., 30.iv.1994, sweep net, X. Wang (BDN no. 01863) GoogleMaps . Paratype: 1 male as holotype.
Etymology From Latin, subula, awlshaped and – atus, provided with, referring to the pointed anal point.
Diagnostic characters
The male differs from other described species of the genus by having a comparatively large and dark body, a small triangular anal point, long crista dorsalis and a rectangular inferior volsella. This species is similar to T. kinkaensis ( Sasa, 1989) , but it is readily separable by the following characters (characters of T. kinkaensis in parentheses): Eyes with wedgeshaped dorsomedian elongation (without); R 2+3 separate (fused with R 4+5), with 6 strong acrostichals (without); ground color of thorax dark brown to black (pale yellow).

Wing ( Fig. 13 View FIGURES 13–18 ). Anal lobe developed. VR 1.06. R 2+3 ends 1/4 distance between R 1 and R 4+5. Costal extension 33 µm long. R with 8 setae, R 4+5 with 6 setae, remaining veins bare. Squama with 11 setae.
Legs. Spur of front tibia 55–60 µm long, without denticles. Spurs of mid tibia 38–40 µm and 20–25 µm long, of hind tibia 60–68 µm long, all with weak denticles. Hind tibial comb with 14 setae. Two pseudospurs present on ta 1 ta 2 of mid and hind legs. Lengths and proportions of legs as in Table 4.
Hypopygium ( Fig. 14 View FIGURES 13–18 ). Anal point small with pointed apex, 13–25 µm long. Tergite IX with 10–12 long setae. Phallapodeme 58–69 µm long; transverse sternapodeme distinctly arcuate, 95–105 µm long, with oral projections. Virga 9–11 µm long, composed of cluster of 7–8 spines. Gonocoxite 168–198 µm long, inferior volsella rectangular, with more than 15 long setae. Gonostylus ( Fig. 15 View FIGURES 13–18 ), 98–100 µm long, crista dorsalis present, megaseta 8–10 µm long. HR 1.71–1.98; HV 2.78–3.04.
Female and immatures: Unknown.
Distribution The specimens were collected with a sweep net flying over snow in early spring in a mountain area in the Jilin Province in Northeast China (Palaearctic Region).
Tokunagaia unicentrata new species
( Figs. 16–18 View FIGURES 13–18 )
Type material
Holotype male. CHINA: Sichuan Province, Yajiang County, (30°02’N, 101°01’E), 3750 m a.s.l., 9.vi.1996, sweep net, X. Wang (BDN no.12258) GoogleMaps . Paratypes: 1 male, Sichuan Province, Kangding County, (30°04’N, 101°57’E), 3700 m a.s.l., 15.vi.1996, light trap, X. Wang GoogleMaps ; 1 male, Sichuan Province, Daocheng County, (29°01’N, 100°18’E), 3750 m a.s.l., 20.iv.1988, sweep net, X. Wang GoogleMaps .
Etymology From Latin, unus, single, centrum, spur and – atus, provided with, referring to the single spur on mid and hind legs.
Diagnostic characters
