Fragilonola fragilis sp. n.

(Plate 6, Figs 4–6 ; gen. figs 37–39)

Holotype. Male, [ Indonesia] Sumatra, Sitahoan, 21–22.XI.1981, leg. Dr. Diehl, slide No.: LGN 2154 (coll. HNHM). Paratypes. Indonesia, Sumatra: 1 female, Prapat, HW 3, 31.I.1984, leg. Dr. Diehl, slide No.: LGN 2156 (coll. HNHM); 2 males, Dolok Merangir, 180 m, collected in 1971, and 5–25.XI.1973, leg. Dr. E. Diehl, slide Nos LGN 2076, LGN 2153 (coll. SMNK).

Diagnosis. The new species is similar to F. igorkostjuki but is easily distinguished by the following characters: F. fragilis has considerably longer ciliation of male antenna, somewhat shorter forewing, much darker colouration of forewing with less light areas, and conspicuously broader whitish postmedial line.

In the male genitalia the new species has considerably thicker uncus, longer tegumen, broader valva, larger, more robust bifurcate harpe with more unequal processes and conspicuously shorter vinculum than in F. igorkostjuki . The aedeagus of F. fragilis lacks the apical carinal process, while the carina of F. igorkostjuki possesses relatively short but well developed thorn-like apical process. The vesica is with fine scobination in both species.

The female genitalia of the new species has somewhat shorter apophyses, much broader, more strongly sclerotized ostium bursae, considerably shorter and thinner ductus bursae being sclerotized in its full length (that of F. igorkostjuki is sclerotized only in its distal section), somewhat larger corpus bursae, and the signa are a pair of remote, more or less equally small, short triangular processes, while the signa of F. igorkostjuki are inequal, relatively small, rounded scobinated plates.
