Diagnosis:

Males: This species can be recognized among congeners by the combination of the following features: the lack of prominent prosomal modification; the broad, apically pointed palpal tibial retrolateral apophysis without a tooth on the inner surface; lamella characteristica extal tip horn-like, with two projections, inner one triangular in ventral view, dorsal one blunt (fig. 5F in Tu & Li, 2006).

Females: Can be diagnosed by the half-octagonshaped dorsal plate of the epigyne (figs 16, 17 in Paik, 1980).

Distribution: South Korea; China, Jilin province. Remarks: Tu & Li (2006) and Seo (2011) have provided informative drawings of three perspectives of the male palps of Gongylidioides kouqianensis and Oe. insulanus , respectively, and their resemblance strongly suggests that these two species are identical. Since Oe. insulanus was published earlier, it has priority over Gongylidioides kouqianensis . The palpal and epigynal morphology of Gongylidioides insulanus is in accordance with the generic description of Gongylidioides in Tu & Li (2006), and supports the placement of this species in Gongylidioides .
