(Figs. 1, 2, 14, 22)
Type material. Holotype. Male, China, Yunnan, Mojiang, 18–19.ix.2008, leg. Han, H.L. & Wang, Y., genit. prep. 6237 M. Fibiger, coll. NEFU. Paratypes (2 males, 2 females). 1 male and 1 female with same data as holotype, genit. prep. 6235 and 6236 M. Fibiger, respectively; 1 male, China, Yunnan, Lincang, 6–7.ix.2008, leg. Han, H.L. & Wang, Y., coll. & genit. prep. 6239 M. Fibiger; 1 female, China, Yunnan, Lancang, 8–9.ix.2008, leg. Han, H.L. & Liu, E., coll. & genit. prep. 6238 M. Fibiger.
Diagnosis. B. bibella belong among the 19 species of the genus Bellulia Fibiger 2008, in the B. bella Fibiger 2008 species-group, which comprises now 5 species with violet forewing tint (Fibiger 2008, 2010). B. bibella differs from these by the much shorter and narrower processes from tegument arms; the less broad valvae; the very narrow left ampulla; the slightly narrower right ampulla; the broad, absent plates of sacculus; and the apically narrower phallus.
Description. Adult (Figs. 1, 2). Wingspan 11–13 mm, forewing broad. Head, thorax, and the forewing with brownish-grey ground colour; antemedial, postmedial, and subterminal lines prominently broad, black; terminal line narrow, marked by black intervenal dots; reniform stigma yellow, outlined with black. Hindwing unicolorous black-brown, with discal spot; fringes on both wings dark grey. Underside unicolorous brown on both wings.
Male genitalia (Fig. 14). Male genitalia with narrow, club-like extensions from fusion of fultura superior and tegumen. Upper 3/5 of tegumen narrow, thread-like; lower part log-like, similar to vinculum and the V-shaped saccus. Processes from fultura superior free, club-like, left one longer, right one apically spatulate, mushroom-like; juxta-anellus plate ring-like, heavily sclerotised; valva broadest subbasally, tapering apically, with prominent heavily sclerotised costa; ampullae asymmetrical, left ampulla narrower than right, relatively narrow, S-shaped; phallus long, narrow, S-shaped, with subapical hump-like process on ventral side; coecum short and broad.
Female genitalia (Fig. 22). Ovipositor short, apically smoothly rounded, setose; posterior apophyses as long as ovipositor; 8th abdominal segment laterally and dorsally very short, ring-like, ventrally completely fused to 7th segment; ostium positioned anteriorly at 7th segment; antrum left-projecting, prominent and thumb-like; ductus bursae with coiled; corpus bursae ovoid, with cross-shaped signum.
Bionomics. The biotope inhabited by B. bibella is dominated by many herbaceous plants and bushes, close to a brook. All specimens were captured at light in the middle of September. The early stages are unknown.
Distribution (Fig. 30). Bellulia bibella is recorded from three localities in Yunnan prov., China.
