Euryeidon monticola Dankittipakul & Jocqué, 2004 from Thailand.

Holotype : 1♂ (IZCAS-Ar 44604), China, Yunnan, Xishuangbanna, Mengla County, Menglun Town, XTBG, Secondary tropical seasonal rain forest, 21°55.428′N, 101°16.441′E, 598 m, 16–31 June 2007, G. Zheng leg. Paratypes: 1♂ (IZCAS-Ar 44605), 2♀ (IZCAS-Ar 44606, Ar 44607), same data as holotype, but secondary tropical seasonal moist forest, 21°54.54′N, 101°17.202′E, 713 m, 1–15 July 2007.

Euryeidon dian sp. nov. resembles E. sonthichaiae Dankittipakul & Jocqué, 2004 (cf. Figs 1, 2 and Dankittipakul and Jocqué 2004: 763, figs 35–37) in that the males have a similar tegular apophysis (Fig. 2A, B). Males can be distinguished by the anterior part of the retrolateral tibial apophysis semi-transparent, and nearly round in ventral view (Fig. 2B, C; vs. retrolateral tibial apophysis strongly sclerotized, bifurcated, with sharply pointed apex), by the dorsal tibial apophysis bifurcated, with two curved and pointed apophyses (Fig. 2B, C; vs. dorsal tibial apophysis absent), by the longer filiform embolus (Fig. 2A, C; vs. embolus shorter), by the conductor being hook-shaped apically (Fig. 2A; vs. prolateral side of conductor greatly excavated to accommodate the embolic tip). Females can be easily distinguished from all known congeners by the bud-shaped copulatory openings (Fig. 1E), by the single-lobed spermathecae lying beneath the copulatory ducts (Fig. 1E), and by the copulatory ducts large, wing-shaped, and occupying the entire vulva (Fig. 1F).
