Complementary description. Male (Fig. 1). Body length 37.3–40.4 mm, humeral width 11.1–12.1 mm. Male endophallus (Fig. 8) long and slender, more than 3 times as long as the median lobe, strongly curved dorsally near apical third; APH defined by the presence of af, limit between BPH and MPH indicated by a dorsal swelling; cs highly reduced, nearly unrecognizable; MPH vaguely subdivided into MT, CT and PB, without significant swelling or protuberance; PB surrounded by sf and provided with si; relative lengths of APH: MPH: BPH: PB: CT: MT = 1.0: 8.4: 1.4: 1.1: 2.8: 4.7. APH slightly curved ventrally at base with im complete and subsclerotized, clearly divided into ab and bb; ab cylindrical, moderately swollen; bb constricted near middle, provided with a pair of rodlike sclerites associated with the paired ejaculatory ducts (Fig. 5a), with gn situated near the apex. Spicules mainly distributed on dorsal surface or along a narrow ventral midline of CT, around the distal part of PB and the whole surface of ab.

Distribution. China: Shandong, Henan, Shaanxi, Anhui, Zhejiang, Hunan, Fujian, Guangxi (new Province record).
Remarks. This species was originally described from Borneo (Pascoe 1858, label of the holotype interpreted as “Borneo?”), but no additional specimen has been reported from there since. Study of series specimens from several localities of China suggest that the "North China " proposed in Pascoe (1866) is the correct type locality of this species. Thus, this species is accordingly excluded from the fauna of Borneo.
