Bellulia basalia Fibiger, new species (Plate 10, figure 3; male genit. plate 19, figure 5; female genit. plate 25, figure 6) Material examined. Holotype: male, Vietnam N, 5 km E Bao Loc, Suoi Loc stream, 24.x.1988, leg. S. Mahunka, J. Oláh & T. Vásárhelvi, coll. HNHM. Paratypes: 2 males, 1 female: same data as holotype; 2 males genit. preps 5922 and 5924, and 1 female genit. prep. 5923 M. Fibiger. Colls HNHM and MF. Diagnosis. Imago (external). Wingspan: 13–15 mm. Forewing: purplish black. Crosslines: black, indistinct, medial shade well marked. Reniform stigma: distinct, round, yellowish, outlined black. Hindwing: greyish brown, without discal spot. Underside: unicolorous grey. Abdomen: grey with black crest dorsally on first segment. Male genitalia. Tegumen and fultura superior: dorsal part of tegumen weak, narrow; ventral part fused with fultura superior with a prominent, loglike process on each side, flattened at apices (apo.), right one shorter and apically broader. Vinculum: short, loglike. Saccus: short, V shaped. Tergite: inconspicuous. Valvae: slightly asymmetrical. Sacculus: strongly asymmetrical, dorsally rounded, right one larger. Ampulla: slightly asymmetrical, narrow medially. Anellus: fused with juxta, forming full circle around phallus. Phallus: broadest by ductus ejaculatorius, slightly curved clockwise, slightly tapered towards tip. Vesica: basally with one small, triangular cornutus; subapically with row of 5 equally formed cornuti (apo.). Female genitalia. Ovipositor: quadrangular, corners rounded. Posterior apophyses: slightly longer than ovipositor. 7 th abdominal segment: heavily sclerotised, posteriorly U shaped by postvaginal plate from 8 th segment. Ostium: slightly displaced to left, positioned anteriorly on 7 th segment. Ductus bursae: long, cylindrical, slightly coiled, basal half membranous, apical half heavily sclerotised (apo.). Corpus bursae: globular, with cross-shaped signum. Differential diagnosis. B. basalia is in size above average for species of Bellulia. Unique in that processes from fultura superior rather short and flattened at apices; vesica with one basal and 5 subapical cornuti in a row; female genitalia with ductus bursae membranous in anterior half, heavily sclerotised in apical half. Distribution. Known only from type-locality in North Vietnam.
