a b c à Fig. 2. Aedeagus of Olibrus kaszabi sp. n.: a. paramere, dorsal view; b. the same lateral view; c. penis, dorsal view; d. Olibrus meiallescens ab. bipustulatus ab. n. elytral pattern. Length of body 1.9—2.5 mm. Aedeagus and parameres see Figs. 2, a —c. This species is similar with 0. permicans RTT. from Manchuria, differing from it in dark coloration of upperside, the absence of elytral microsculpture, developed in 0. permicans RTT, along the suture, and the size of body not so large. From all species of Olibrus inhabiting in Mongolia 0. kaszabi differs very well in having the second joint of club short and very transverse (Fig. la) and the metathorax almost impunctured. Holotype — Suchebator aimak, 44 km. SSW Baruun urt, 1050 m., 2 — 3. VIII. 1965 (Nr. 349), male. Paratypes: 113 specimens (localities are listed in the review of the examined material). Olibrus meiallescens FLACH This species was described on the base of the female features. Males differ in having the upperside more shining and less distincly microsculptured, coloration more dark, often without distinct bronze tint, head more sparsely punctured. Olibrus meiallescens FLACH ab. bipustulatus, nov. (Fig. 2d) Each elytron with large flavous spot. On the left elytron it lays before middle and almost touches suturai margin, on the right elytron this spot is not so large, more round, lays immediately behind middle and reaches neither lateral nor suturai margin (Fig. 2d). Length 2 mm. South Gobi aimak, Tachilga ul between Zogt-Ovoo and Dalanzadgad, 1550 m., 8. VII. 1967 (Nr. 902), 1 female-holotype. Brief analysis of Mongolian fauna The mongolian fauna of Phalacridae is rather poor in number of species, as compared with faunas of Europe, Caucasus or Middle Asia. It includes only 2 genera and 7 or possibly 8 species, that may be arranged in different zoogeographical groups and distributed within the Mongolian territory in different manner. Four such groups compose the Phalacrid fauna of Mongolia.
