Fig. 311–314  
 Cheumatopsyche kuranishii, new species has a combination of trilobed segment X; shortened apicoventral setose lobes and rather elongate convex smooth mesocaudal lobe. It is close to C. anonima, new species from which it is easily distinguished by the presence of extremely short segment IX, the unusually elongating smooth mesocaudal lobe and by the unique shape of the harpagones including a very wide basis abruptly narrowing at mid-length and broadening apex.   
Male. Body pale fulvous. Maxillary palp formula I-(III, IV)-II-V, segment V as long as sum of segments I–IV. Head dorsum darker fulvous, with 7 warts of slightly lighter colour. Swollen setal wart absent on both proepisterna. Setal surfaces present on precoxale. Pretarsal claws asymmetrical, laterally flanked by setal bundle. Mid- and hind-leg claws asymmetrical. Spur formula 244. Posteroapical spur on the forelegs half as long as lenght of anteroapical spur. Forewing length 6.4 mm. Forewing membrane evenly pale fulvous with slightly darker veins and some irroration of pubescence especially on apical cells. Forewing crossveins m-cu and cu symptotic, meeting in oblique line. Sc and R separate before costa. Cu2 and A1 running separately before costa. Hind wing Sc and R meeting apically of r by a distance equal to length of r lenght, r located basally of s by a length equal to half length of r. Fork 1 absent.  
Male genitalia. Abdominal segment IX fused annularly, very short abbreviated, tergum half as long sternum (Fig. 311). Anterior margins of segment IX regularly bow-shaped, drawn slightly dorsally in lateral aspect (Fig. 311). Apical lobe on posterolateral margins blunt triangular (Fig. 311); slightly directed ventrad, located well above less sclerotized articulation cavity of gonocoxites (Fig. 311). Antecosta well developed, widening before margin of sharp dorsal and ventral narrowing, external groove of antecostal suture well developed. Spine row on posterior margins of segment IX intermittent and heterogeneous, missing on segment X (Fig. 311); spines on dorsolateral spiny lobes 2 times longer than spines on apical lobes; in dorsal view, dorsolateral spiny lobes forming pair of regularly rounded lobes separated in middle by wide excision (Fig. 312). Intersegmental gap between segments IX and X stepwise, almost right-angled (Fig. 311). Segment X short; nearly quadrangular; in lateral view bordered distally by upwardly curving, smooth, mesocaudal lobe and slightly ventrad curving apicoventral setose lobes (Fig. 311). Segment X clearly triangular in dorsal view (Fig. 312); mesocaudal lobe triangular, protruding apicoventral setose lobes (Fig. 312). Dorsal interlobular gap almost absent, filled by mesocaudal smooth lobe; dominating genitalia in dorsal and ventral view (Fig. 311, 312). Transverse sutures well developed, crossing segment X obliquely. Longitudinal sutures narrow, forming continuation of apicoventral setose lobes (Fig. 311); meeting transverse sutures into Y. Smooth mesocaudal lobe large, ending in protruding triangular margin, curving dorsad, forming rim in lateral view (Fig. 311). Apicoventral setose lobes short, orienting posterad parallel-sided; straight-cut apically in lateral view (Fig. 311); originating from apicoventral corners. Lateral setose areas (superior or preanal appendages) forming elevated warts on basis of short, apicoventral lobes. Coxopodites exceeding apex of segment X, straight (Fig. 311); dilating gradually slightly toward apex; curving uniformly in ventral view (Fig. 313). Harpagones with broad basis, abruptly narrowing or even constricted at mid-length (Fig. 311, 313); apex wide in lateral view. Phallotheca with short, shallowly broadening, ventrad curving basal part (Fig. 314); horizontal part with convex dorsum and concave ventrum; small constriction present before apex. Phallothecal apex broadening ventrally in lateral view. Endophallus long, running through almost entire phallotheca, ending in narrow tube at gonopore. Chitinized endothecal process elongate, straight-cut distally. Phallotremal sclerites rounded in lateral view. Vestigial, membranous, ventral, endothecal lobes visible.
