Similar to Hoplitis beijngensis Wu, the main differences are: central part of clypeus convex, not straight; abdominal tergites without white hair-spots or hair-bands; scopa ferruginous, not yellowish.Holotype (?), Inner Mongolia; Zhenglan B., Xilin Gol L..13-Ⅶ-1987, coll. Bao Xueming. Paratype 1 (?) , same date as holotype; Horqin Right Wing Front B., Hinggan L. 27-Ⅵ-1983, coll. Wang Xiuying. 5. Hoplitis (Tridentosmia) minuta sp.nov. (Figs. 7-11)(?), Length 6mm. Closely related to Hoplitis (Tridentosmia) tridentata Duf. et Perr., but easily identified by the smaller body; apex of abdomen with thtee slender processes; 7th-8th sternites and genitalia different.Holotype (?) , Inner Mongolia: Alxa Right B., Alxa L., 4-Ⅵ-1986, Chang Yuling. Paratvoe 1 (?), same locality as holtype, 30-Ⅵ-1986, coll. Tu Hu.6. Hoplitis mongolica sp.nov. (Figs. 12-16)Length 8.5mm. Similar to Hoplits scita Eversmann, the main differences are: center of apex of abdomen concave , lateral part lobe-like; legs black; 2nd abdominal sternite normal without transverse carina; 7th-8th sternites and genitalia different.Holotype (?) , Inner Mongolia; Zhenglan B., Xilin Gol L., 13-Ⅶ-1987, Bao Xueming.7. Paranthidiellum campulodonta sp.nov. (Figs. 17-23)(?) Length 6.5mm. Similar to Paranthidiellum lituratum Panz., but center of 7th abdominal tergite concave, not straight; fore femora normal without tooth at basal part; each side of 5th sternites with a large darktooth, not the 6th sternite.Holotype (?) . Inner Mongolia, Ejin B., Alxa L., 20-Ⅵ-1986, coll. Bal Jinshan.8. Anthophora clavitarsa sp. nov. (Figs. 24-29)(?) Length 9-10mm. Similar to Anthophora borealis Mor., the main difference are: clypeus yellow without black spot; all tarsi yellow-brown, not black; hind-basitarsi flat and apex broad; middle last tarsi normal without lateral hair-tuft; 7th-8th sternites and genitalia different.Holotype (?) , Inner Mongolia: Alxa Right B., Alxa L., 28-Ⅴ-1987, coll.
