TAXONOMIC PART Heteroconis helenae sp. n. (Figs 1-5) Holotype — Male: "Vietnam, Da Lat, Thac Prenn waterfall, 1120 m a.s.l., 1.: S. Mahunka, Gy. Sziráki, L. Zombori". Deposited in the Hungarian Natural History Museum, Budapest. Paratypes: 1 female, Vietnam, Da Lat, Cam Ly area, rain forest, 4. XII. 1994.; 1 female, 6. XII. 1994. Both deposited in the Hungarian Natural History Museum, Budapest. Description — Palpi and the sclerotized parts of the head capsule dark brown. There is not corniform projection between the male antennae. Antennae 18-segmented. Flagellar segments 7-8 and 11-15 brown, scape, pedicel and the other flagellar segments white. Scape about three times, pedicel two times as long as broad. Length of antenna 1.0-1.1 mm. Eyes black and rather small. Length of fore wing 2.7-3.0 mm, of hind wing 2.5-2.7 mm. Wing membranes mostly brown, but along some veins and near their apex colourless (Fig. 1). Basal cross veins Rs-M and M-Cuj of fore wing meet M between the median thickenings. In hind wing radial cross vein meets Rs on branch R?+3> but very close to the fork. Thorax pale ochreous with brown apodemes and shoulder spots, and with a brown dorsal band on prothorax. Legs ochreous or light brown, but coxa and trochantin darker. Abdomen white. Male genitalia (Figs 2-4) well sclerotized. Gonocoxite proximally wide, caudally slender. Stylus large, wide. Ninth sternite rather narrow and curved backwards with a weak, in lateral view acute, projection. Hypandrium has a caudal projection, ending in a median and two lateral spines (similar to the ventral process of some other Heteroconis species, e.g. H. papuensis Meinander, 1990). Behind the rather long dorso-lateral apodemes there is a separate dorsal projection on the penis. End of the penis curved up- and forwards. In the female terminalia (Fig. 5) the gonapophyses laterales fused into a short and wide plate with a distinct apical incision. Their lobes densely haired with some stronger bristles. Caudal part of receptaculum scminis with two lobes, one of which is the continuation of the duct, well sclerotized and provided with very strong spines inside (Sziráki 1998, Fig.l as "Heteroconis sp.l"). Remarks — Because of the absence of the corniform projection on the male head and the features of wing venation the new species somewhat resembles the Malayan H.fusca Meinander, 1972, but owing to the long and wide stylus, the shape of the gonocoxite, the caudal projection of the hypandrium and the structure of female terminalia, Heteroconis helenae differs clearly from all hitherto described Heteroconis species. Etymology — I dedicate this species to my wife.
