Stenoloba chlorographa Kononenko & Ronkay, 2001 . Insecta Koreana 18(2): 99, Figs 4 , 25, 44. Type locality East Nepal, Koshi (NSMT).

Stenoloba viridimicta, sensu Yoshimoto 1995 (nec Hampson 1910). Moths of Nepal, 3:69, pl.109, fig 2, text fig. 616.

Note. The species was misidentified by Yoshimoto (1995) as S. viridimicta ( Yoshimoto 1995, nec Hampson 1910), corrected by Kononenko & Ronkay (2001).

Material examined. 1 male, China, Autonomic Region Xizang, Yigong, Shuangyu , 7.viii.2017, Hui-Lin Han , genit. prep. hhl-3551-1 ( NEFU) .

Diagnosis ( Figs 4 , 12 ). Stenoloba chlorographa belongs to the S. viridimicta species - group ( Kononenko & Ronkay 2001). Externally it resembles S. viridimicta Hampson, 1910 ( Fig. 5 ), but can be distinguished by its larger size (28 mm vs 25 mm in S. viridimicta ) somewhat broader shape of forewing (vs narrow, with parallel margings in S. viridimicta ) and the forewing pattern with sharply defined subbasal field (vs sharply defined only in ventral half in S. viridimicta ); missing of longitudinal black streaks parallel to costal margin of wing and black bordering of subbasal field (vs well expressed longitudinal black streaks in S. viridimicta ) and presence of broad blackish-brown subapical patch and clear greenish apical mark (not presented in S. viridimicta ).

In the male genitalia ( Fig. 12 ), S. chlorographa differs by the shape of valva, which is unlike to S. viridimicta , has parallel distal and ventral margins at its basal two third and gradually tapered in to thin, slightly curved, sticklike apical third; costa bears a sclerotised bar which terminates in the apical third of the valva. In S. viridimicta valva gradually tapered from its base to the apex, without sclerotised costal bar.

Distribution and bionomics. This rare species had been known only from Nepal ( Yoshimoto 1995, reffered as S. viridimicta ; Kononenko & Ronkay 2001) and here it is reported for China from the Autonomic Region Xizang for the first time. The specimen was collected in first week of August in montane subtropical forest at troughly 2000 m. Its presence in Southwest China significantly extends its distribution eastward from the type-locality.
