Remarks: The diagnosis of Ansiulus given by TAKAKUWA (1940a) is inadequate. It is quite clear that this genus is most closely related to Skleroprotopus Attems, some 16 or 17 so far known forms of which are wide-spread in North China, Korea, the Soviet Far East and Japan. Similarities between the two genera, aside from the same geographical pattern, lie in the habitus, structure of male leg-pairs 1 and 2, as well as in gonopods and vulvae. The main differences between them to be mentioned are the presence of multi-jointed leglike telopodites of male pair 7 and lack of the latter' s modifications of coxae, as well as the more or less strongly reduced telopodites of posterior gonopods in Ansiulus. Thus Skleroprotopus seems to be a somewhat aberrant derivative of Ansiulus. POL YDE SMIDAE Epanerchodus bifidus Takakuwa, 19 54 Localities: Pyongyang City, Mt.
