RUSSIA, Maritime Province: 63 4Ƥ, Ussuriskii District, litter in broad-leaved forest near Gornotaezhnoe Village, 43°42’N, 132°09’E, May-June 2007 (M.M. Omelko). Diagnosis. Males of this species can be easily distinguished by their truncate tibial apophysis. The bulbus of D. biglobus is rather similar to those of D. coreanus Paik, 1986 and D. excavatus (Schenkel, 1963) because of the small tooth on the tegular apophysis. Females of D. biglobus are somewhat similar to those of D. excavatus (Schenkel, 1963) in the shape of anterior epigynal margin, but differ significantly in the shape of their median septum and insemination ducts. Drassyllus biglobus females are also similar to D. amamiensis Kamura, 2011 known from southern Japan and can be easily distinguished by the shorter lateral margins of the epigynal fovea. Description. Measurements (3/Ƥ). Total length 6.80/9.05. Carapace: 2.80/2.95 long, 2.20/2.25 wide. Spination of leg I and II are the same in both sexes: femur with 2 dorsal and 1 retrolateral spine, tibia with 2 retroventral spines and metatarsi with 2 pairs of ventral spines. Male. Carapace and sternum light brown (Fig. 1). Abdomen dark gray with brownish scutum occupying about 1/3 of abdomen. Legs light brown except for tarsi and metatarsi I and II which are yellowish. Palp as in Figs 3–4, femur-tibia yellowish, cymbium brown; tibial apophysis about length of tibia, sharply abrupt (truncate) on the top, ventral edge with small spine; median apophysis (Ma) longer than wide, hook (Mh) placed in the lower part of apophysis close to the tip of tibial apophysis; tegular apophysis (Ta) triangular, wider than high, with small tooth (Tt) below the tip; embolus long, longer than ½ of cymbial length. Female. Coloration like in male, but somewhat lighter. Epigyne as in Figs 5–7, anterior epigynal margin (Am) inverted U-shaped, marginal socket deep (Fig. 7), lowest portion of anterior epigynal ducts (Ad) with small gland (Sg), septum (Se) in widest part is not wider than diameter of spermathecae (Sp), distance between outer margins of posterior epigynal ducts (Pd) not wider than that between outer margins of spermathecae. Length of legs and leg joints: Distribution. The species is restricted to Far East Asia and occurs from Jeju Island in East China Sea to Ussuriysk, south part of Maritime Province in Russia (Fig. 8). In Russia it was found in a single locality, while in Korea it was found in almost 50 localities across whole country. The type localities of D. biglobus and D. truncatus lie close to each other.
