Macdunnoughia (Sclerogenia) Jessica (Butler, 1878) comb. n. (Plate: 5) (Ann. Mag. Nat. Hist., (5)1:201. - Plusia) Examined material: 1 male, Vinh Phu, Tam Dao, 1200 m, 20.1. 1986, leg. Mahunka and Oláh. Slide No. 19 59 Ronkay. The generic relegation of this peculiar species had been changed in several times and its phylogenetic relationships are also had not been satisfactorily clarified. In my opinion the special configuration of the vesica (Fig. 29) undoubtedly shows the common evolutionary line of Macdunnoughia and Sclerogenia, and the unusual saccular structures of Jessica ÍFig 28) and the species of Macdunnoughia can be derived from the same ancestral stage. The distribution of Jessica is restricted to the northern part of the Indo-Australian Region (S Himalaya, India, S China, N Philippines) and the Pacific zone of the Palaearctic Region; new to the fauna of Vietnam. Dactyloplusia hedysma (de Joannis, 1928) comb. n. (Plate: 6) (Ann. soc. ent. France, 97 (3-4): 364. - Phytometra) (= Trichoplusia scelionis Chou et Lu, 1980, syn. n.) Examined material: 1 male, Vinh Phu, Tam Dao, 1200 m, 20.1.1988, leg. Mahunka and Oláh; 1 female. Cue Phuong, 400 m, 17.X. 1986, leg. Mészáros, Oláh and Vásárhelyi. Slides Nos 2086 (male), 3019 (female) Ronkay. An Indo-Australian species with only very few known localities and specimens. It was reported from Vietnam (de Joannis), S China (Chou and Lu, 1980) and newly discovered in Sumatra as a result of the lepidopterological exploration of Sumatra carried out by Dr. E. Diehl. The phylogenetic relationships of the species of Dactyloplusia, based on the character istics of the type species, impulsa (Walker) was discussed by Kitching (1987). By the main characteristics of the male and female genitalia of Dactyloplusia represented by impulsa, three further, externally very different species can be placed into this genus as follows: hedysma (de Joannis), mutans (Walker), comb. n. and indica (Ronkay), comb. n. It is important to note that the latter three species are similar to each other but they have some im portant differences in the configuration of the male genitalia and one of them, indica has reduced abdominal coremata.
