dominai sternite with an unmodified lateral ridge similar to male, but on the sixth sternite the apicomesal process is very small and blunt. Genitalia similar to A. dangorum. Hind wing venation, structure of fifth and sixth abdominal sternites and the upcurving process on the lower branch of tenth segment clearly align this species in the Synagapetus subgenus, " rudis" group and " mitis" subgroup. The asymmetry between the upcurving processes on the lower branches of the tenth segment is a unique feature, and all the other structural units of the genitalia differ from the known species. This asymmetry was emphasized when I named this species. Asymmetry: khong can xing in Vietnamese. Holotype o. Cuc-Phuong, 400 m, Vietnam, 18. X. 1986. Singled along a karstic spring brook in the jungle from shore vegetation leg. Oláh. Allotype g Hoa-Binh, Vietnam, 8 km from Hoa Binh in the direction of Da Bac, singled along a small spring brook, 21. X. 1986, leg. Oláh. Paratypes 3 8 from Cue Phuong, same data as for holotype; 2 8 from Hoa Binh, same data as for allotype. Deposited at the Zoological Department, Hungarian Natural History Museum, Budapest. Right pair of wings of holotype 8 mounted as dry microscopic preparation. Caustic potash-treated abdomen of holotype and allotype and the remaining part of their body together with the untouched paratypes are stored in a single airtight vial filled with 70 % ethanol. Agapetus caimoc sp. n. (Fig. 6) Male (in alcohol). General colour brown. Wing membrane brown, hairs darker. On fore wing whitish hyaline area along the costal tip of Sc, along the cross-vein r-m, below the stem M a larger patch in the thyridial cell, along the costal tip of Cu 2 and a long narrow patch in the proximal half of cell between A-^ and A 2 . On hind wing Sc short ending at about anastomosis, apex of Rj absent, fork 1 present. Length and largest width of fore wing 3. 81. 3, those of hind wing 3-1 mm. Fifth abdominal sternite with a well-developed, unmodified ridge and the sixth sternite with a long narrow apicomesal process. Fig. 6. Agapetus caimoc sp. n. - A = male genitalia, lateral, B= dorsal, C= ventral, D= phallic apparatus, lateral, E= fifth and sixth abdominal sternites, lateral, F= male wings Male genitalia. Ninth abdominal segment synsclerotized, triangular elevation both anteriad and posteriad. There is also an apicomesal ventral lobe. Tenth segment forms an almost tube-like structure with a deep dorsoapical excision and with a pair of a symmetric hooks situated apicoventrad. The left hook is larger. There is a saddle-shaped sclerite welL visible and much elongated compared to the three species known to have this sclerite (A. tamr rangensis , A. dangorum , A. danbang). Seen in dorsal and lateral views the elongated distal
