mesoscutellar appendage and postscutellum densely and finely punctured, moderately shining. Mesopleuron densely and finely punctured, clearly shining. Abdominal tergites with fine coriaceous surface sculpture, shining. Penis valve in Fig. 16. OOL:POL:OCL=12:l 1:5. Ratios of the antennái segments = 6:4:24:24:24:22:19:17:17. Ratios of the hind tarsal segments without claws = 25:15:12:5:10. Length of antenna : length of costa + stigma = 80:65+17. Genal length : diameter of the front ocellus = 1:5. Longest axis of eye : length of 3rd antennái segment = 1:1. Length: 4.5 mm. Length of fore wing: 3.6 mm. Holotype: male: "Mongolia, Central aimak, Bugijn az achuj im Geb. Bogdo ul., 36 km SW von Ulaan-Baator, 1650 m, Exp. Dr. Z. Kaszab, 1968, Nr. 939, 10.VI.1968". Etymology: the name trilobita refers for the special shape of penis valve which has 3 lobes (Fig. 16). The special structure of its penis valve (Fig. 16) differs the new species from every other species. This species represent an unique character in the genus Pristiphora (sensu lato). Pristiphora memoriakaszabi sp. n. (Figs 7, 9, 11) Body ochraceous (light brownish red) including antennae and legs. Metanotum between mesoscutellar appendage and the postscutellum, the sunken area behind the postscutellum black. The lateral sunken areas of the mesonotum near to the lateral lobes brown. Tergite 1 covered mainly with brown. Tergites 2-5 frequently covered with light brown shadow in the middle. Sawsheath dark brown in dorsal view. Cenchri brown. Wings hyaline, venation, costa and stigma yellow. Head very finely, shallowly and very sporadically punctured, strongly shining. Head without hind carina and subparalell behind the eyes. Frontal area raised but not clearly bordered. Clypeus very shallowly emarginated, nearly subtruncate. Claws with small inner teeth. Mesonotal lobes densely, shallowly and finely punctured, shining. Mesoscutellum, mesoscutellar appendage and postscutellum sporadically punctured, nearly smooth and shining. Mesopleuron smooth and shining. Abdominal tergites with fine coriaceous surface sculpture, shining. Head and thorax covered with sparse, white pubescence, about 1/3 times as long as the diameter of the front ocellus. Sawsheath small and acute in dorsal view. Cerci long reaching over the apex of the sawsheath (Fig. 7). Lancet in Fig. 3. OOL:POL:OCL = 15:19:18. Ratios of the antennái segments = 10:5:30:25:23:19:17:15:16. Ratios of the hind tarsal segments without claws: 35:17:12:7:15. Length of hind tibia : length of ovipositor = 85:57. Length of inner hind tibial spur : length of hind basitarsus : maxi-
