Stenoloba brunnescens Kononenko & Ronkay, 2000 (Figs 17, 44) Stenoloba brunnescens Kononenko & Ronkay, 2000, Insecta Koreana, 17(3):161, fig. 17 (Holotype: male, Vietnam, Prov. Lao Cai, Fan-si-pan Mts., 1920 m, 4 km SW Cat Cat, HNHM, Budapest). Material examined. 4 males: 1 male, China, Prov. Yunnan, Simao, 18.iv.2013, H.L. Han & C. Zhang leg., slide 6138-1; 1 male, Prov. Yunnan, Longba, 26.vi.2013, H.L. Han & C. Zhang leg., slide 6140-1; 2 males, Prov. Yunnan, Wanding, 25.vi.2013, H.L. Han & C. Zhang leg., slide 6139-1, 6141-1, coll. NEFU. Diagnosis. Stenoloba brunnescens (Fig. 17) is similar to S. plumbeoviridis and S. plumbeobrunnea described above, being the representative of S. clara species group. Externally it differs from other members of the group by its dark reddish-brown colouration of forewing, without green or olive-greenish shining. The male genitalia (Fig. 44) also refer to its affinity with the taxa of the S. clara group by the shape of valva with swelling in the medial part. The closest species to S. brunnescens is newly described S. plumbeobrunnea, from which the former differs by narrower and less curved valva with shorter but broader apical part, directed distally. The female genitalia (illustrated by Kononenko & Ronkay, 2000) differ mostly from those of the related taxa by their much broader antrum with significantly longer postero-lateral arms. Distribution. Southwest China (Prov. Yunnan), North Vietnam. Moths were collected in April and June. The species formerly was known from North Vietnam only; hereby it is recorded for China for the first time. New data considerable extend the distribution pattern of S. brunnescens.
