【Abstract】 In recent years, a new cockroach was found infesting in houses, on ships and naval vessels of several north-eastern and eastern provinces of China. It occurs indoor mixed with other cockroaches, and as a dominator in some places. Identification was made based on several batches of specimens sent by those units concerned, it is determined that both the genus and species names belonging to Pseudomopidae are new to science, and specimens of the same species have also been collected outdoor from Tienmushan Mountain, Zhejiang; Lou-guan-tai, Shaanxi; and Qingdao, Shandung.This paper presents a description of the new genus and new species. Type specimens are deposited in the Institute of Plant Protection, Chinese Academy of Agricultural Sciences.Discalida gen. nov.Genotype: Discalida pallidimarginia sp. nov.Ventro-cephalic margin of cephalic femora armed after type B, and with three heavy-spines distad (B3). Discoidal vein of tegmina and wings forking before distal portion, ulnar vein of wings with incomplete branches, abdomen unspecialized of male, subgenital plate symmetrical, styli normal and symmetrical.Each of the three features mentioned above: spine pattern of cephalic femora, vein pattern of tegmina and wings, and subgenital plate of male, is similar to Scalida Hc-bard, Symploce Hebard and Margattea Shelford, respectively, but none of these three genera is endowed with all of those features like this type. For this reason, it should be a new genus in addition to the genera established before.Discalida pallidimarginia sp. nov. (Fig. 1)Size medium, dark brown, both sexes somewhat dimorphous. Vertex of male slightly concaved and with several transverse wrinkles between eyes (Fig. 3). There are two1 pale and translucent bands on lateral margins of pronotum and humeral areas of tegmina in male. Flying organs normally developed, beyond the end of abdomen. Ventral-cephalic margin of cephalic femora armed after type B3 (Fig. 2). Discoidal vein of tegmina and wings forking before distal portion, ulnar vein of wings with 3-4 complete and 3-4 incomplete branches, apical triangle inconspicuous. Dorsal surface of male abdomen unspeeialized. Anal plate triangular, much shorter than subgenital plate, with obtuse angle at apex in male (Figs. 4a, b), while in female, sharp angle of apex and exceeds the subgenital plate (Fig. 5). The male subgenital plate symmetrical, styli normal and equally developed (Fig. 4).Measurement: male, body 13-14, pronotum 3-3.5, tegmina 12-13, total 16-19 mm; female, body 12-13, pronotum 3.5-4.0, tegmina 10-11.5, total 14-16 mm.Distribution: Qingdao, Shandung; Yingkou, Liaoning; Shanghai; Tienmushan Mountain, Zhejiang; Lou-guan-tai, Shaanxi.Holotype (male) and allotype (female): Liaoning, 19. Ⅷ. 1981; paratypes: Shanghai (2 males, 11 females), Ⅲ. 1980; Liaoning (8 males, 12 females), 19. Ⅷ. 1981; Tienmushan Mountain, Zhejiang (1 male), 30. Ⅵ. 1957; Lou-guan-tai, Shaanxi (1 male), 3. Ⅷ. 1954; Qingdao, Shandung (1 male, 2 females), 13. Ⅵ. 1979.更多还原
