Type species: Teulisna maculata Fang, 2000 , by present designation.

Diagnosis. The only species of the new genus ( Fig. 9, 10 ) is externally reminiscent of members of the genus Mithuna Moore, 1878 (illustrated by Holloway 2001) and has a broad forewing with a strongly convex costal margin. In male, the subcostal area between the veins R1 and R2 bears a cluster of androconial scales, which is similar to Sundabitecta gen. n. The female has forewing markings similar to male but the ground colour is darker, greyish-brown whereas it is ochreous brown in the male. The male genital capsule structure of Fangeulisna gen. n. ( Fig. 97 ) is reminiscent of Bitecta but differs clearly in the long costa occupying the whole dorsal margin of the valva (vs. proximal one-third in Bitecta ), and the lamella centralis stretching along and dorsally fused with the costa (it is articulated with the distal saccular process in Bitecta ), and forming with it a swollen saccate and setose-spinulose ‘cucullus’, which is unique among the Teulisna sensu lato. The distal saccular process of Fangeulisna gen. n. is narrow and has a reduced dorsal branch. The juxta of the new genus is frame-shaped with a short caulis, which is similar to Bitecta and Teulisna . The vinculum of Fangeulisna gen. n. is short and lacks the coremata and sclerotisations, which is similar to Sundabitecta gen. n. The female genitalia of Fangeulisna gen. n. ( Fig. 149 ) are reminiscent of Bitecta but differ in the short ductus bursae lacking the sclerotised plate, the posteriorly sclerotised corpus bursae, the anterior section of the corpus bursae bearing a signum, and the reduced and conical appendix bursae, which is well-developed and utricular in Bitecta .

Etymology. The generic name is an aggregate of the surname Fang and the genus-group name Teulisna . The new genus is dedicated to Dr Fang Chenglai, author of the Arctiidae volume of the fundamental book series “ Fauna Sinica ” ( Fang 2000). Gender is feminine.

Taxonomic content. The new genus is currently monotypic: Fangeulisna maculata ( Fang, 2000) , comb. n.
