Remarks. A warm-temperate species distributed in northern and central China. Although the species is unlikely to occur in Vietnam, previous research confirmed its occurrence in north and central Vietnam (Le 1995a; Do 1994; Pham 1995c, 2010; Huynh & Nguyen 2004a). Unfortunately, further examination was not possible because all previously collected material has been lost. Do (1994) noted that the population found in Vietnam has three pairs of spermathecal pores in 6/7/8/9, small genital markings close to the male porophores and spermathecal pores, mushroom-shaped accessory glands, and simple intestinal caeca. However, due to the fact that this species is found outside its known areas, the records in Vietnam require confirmation with fresh reference material.
