Diagnosis. Front broad. Anterolateral borders moderately convergent. palm of major male chela without supramarginal groove adjacent to lower border. G 1 ( Fig. 10 View FIGURE 10 f) with palp long, reaching up to distal half of horny endpiece; this last one has inclined flanges, but no strong torsion ( Fig. 11 View FIGURE 11 c); terminal opening at base of deep emargination of distal margin ( Fig. 11 View FIGURE 11 b). Genital opening of female ( Fig. 11 View FIGURE 11 a) and thus also direction of the opercle's edge slightly oblique in respect to median line of sternum.

Distribution. Korea, Japan, Taiwan, China, northern Vietnam. The northern limit in China is in Zhejiang Province, Ise Bay in Japan. Southwards the species reaches Hainan Island, China and northern Vietnam.

Remarks. The species is easily recognisable by the peculiar shape of the G 1, especially the large size of the palp. U. lactea may easily be distinguished from U. perplexa , with which it may be sympatric at least in the Ryukyu Islands, by the lack of a supramarginal groove on the major chela palm as well as by the weakness of the subdistal tooth on the fixed finger of the same limb ( Figs. 10 View FIGURE 10 b –e), which is more prominent in U. perplexa and makes it easily distinguishable from its congener.

The southern distribution of this species is not well known. This applies especially to the Ryukyus, from which it was reported by T. Sakai (1976). Although Sakai mentioned the presence of U. lactea in the Ryukyus, but he did not list U. perplexa from Japan. Sakai probably ignored Crane's record of U. perplexa in the Ryukyus. Crane (1975), however, only recorded U. perplexa from this area and our material also belongs to this species. On the contrary, we have not seen any specimen of U. perplexa from China. The same applies to our few specimens from Taiwan, which all belongs to U. lactea , although the species has been recorded from Taiwan several times (see Ng et al. 2001). It has to be checked if U. perplexa and U. lactea exclude each other or if they are sympatric in part of their range. The factors limiting the distribution of the two species also remain unknown. The median tooth of the gastric mill of U. lactea ( Fig. 14 View FIGURE 14 a) is unique among all member of the U. lactea- group, but slightly similar to U. perplexa rather than others. But regarding the form of the lateral tooth plate of the gastric mill ( Fig. 15 View FIGURE 15 a) and the number of teeth on it, numbering 22 and being comb-shaped, ally the species with U. annulipes and U. albimana .
