Zorochros mansusanensis Han 2000 : Cate 2007: 193, nom. emendation.

Type materials. Holotype male, Mt. Mansusan, Buyeo-gun, CN, 12.VI.1999, leg. Taeman Han. Paratypes: 2 males, ditto. The type specimens are preserved at NAAS.

Description. Body 2.5 mm long and 1.0 mm wide, elliptic, more or less elongate, convex. Color black, opaque, but second antennomere, apex of mandible and legs red-brown; femur dark brown. Punctures fine, dense.Vestiture short, dense, recumbent, whitish yellow ( Fig. 1 View FIGURE 1 C). Head flat between eyes; surface rugose; frontal carina complete, rounded, bifurcated at base. Mandibles bidentate. Labrum semicircular, 1.8 times as wide as long. Maxillary palpi hatchet shaped; fourth segment subtriangular, 1.8 times as long as wide. Antennae slender, 11th antennomere not attaining the apex of pronotal hind angle; first antennomere large, swelling; second cylindrical, 1.25 times as long as third ( Fig. 2 View FIGURE 2 C); third cylindrical; fourth to tenth feebly serrate, 1.6 times as long as third. Pronotum convex, 1.2 times as wide as long, broadest at middle; anterior margin slightly prolonged forwards at middle; lateral margins arched suddenly narrowed towards head, not sinuate at base of hind angles ( Fig. 3 View FIGURE 3 C); disc punctuated densely and minutely, large granules forming triangular area on anteromedian longitudinal part ( Fig. 3 View FIGURE 3 G); hind angle short, stout at base, sharped at apex, with dorsal carina extending to basal one third along lateral margin ( Fig. 3 View FIGURE 3 C). Prosternum broadest at middle, with distinct granules on anteromedian part; posterior process bent inwardly in lateral view. Scutellum subequal in length and width, anterior margin smooth ( Fig. 2 View FIGURE 2 G). Metacoxal plate flat, distinctly expanded at middle of posterior margin. Elytra elongate, disc flat, parallel-sided in basal two third; humeral mucro indistinct; striae distinguished, but fifth one weakly depressed at base, sixth obsoleted. Abdomen with seventh sternite semicircular, 2.5 times as wide as long. Aedeagus fusiform. Median lobe wedge shaped, 1.3 times longer than telomeres. Paramere slightly attenuate towards apex; telomere stubby at apex, with rather weak three major setae located anteriorly; basimere feebly arcuate, broadest in basal one-third ( Fig. 4 View FIGURE 4 D, E).

Female.unknown.

Distribution. Korea.

Etymology. The specific name, Z. mansusanensis , was derived from its type locality, Mt. Mansusan, in Korea.

Notes. This new species closely resembles Z. gurjevae Dolin 1995 from Kazakhstan and Mongolia ( Fig. 1 View FIGURE 1 D; 2D, H; 3D, H; 4G), but is distinguishable by the relatively longer second antennomere, at least 1.2 times as long as third (0.97–1.0 times as long as third in Z. gurjevae ), and the relatively shorter pronotum ( Table 1 View TABLE 1 ). The prosternum of the novel species has larger granules on anteromedian region ( Fig. 3 View FIGURE 3 D, H), the median lobe of the male genitalia is 1.3 times as long as the telomere, and the apex of the median lobe is distinctly steeple-shaped at the apex. In Z. gurjevae , the median lobe is 1.5 times longer than the telomere and the telomeres are stouter ( Fig. 4 View FIGURE 4 F). This new species was found in gravel.
