‘OEDOTHORAX’ BIANTU ZHAO & LI, 2014 INCERTAE SEDIS

Oedothorax biantu Zhao & Li, 2014: 36, figs 67A–F, 68A, B (Df).

Type material: Holotype: China, Yunnan: Menglun Town: Xishuangbanna Tropical Botanical Garden (21°54’38’’ N, 101°16’518’’ E), c. 627 m, bamboo plantation, fogging, ♀ 22.xi.2009 (not examined).

Diagnosis:

Females: This species differs from all Oedothorax, Mitrager, Callitrichia and their related genera by the tibial chaetotaxy (1-1-1-1), the knob on each side of ventral plate of the epigyne and the long slits on the ventral plate (figs 67A and 68A in Zhao & Li, 2014).

Males: Unknown.

Distribution: Known only from type locality.

Habitat: See collecting data of holotype.

Remarks: This species has tibial chaetotaxy 1-1- 1-1, unlike the uniform pattern 2-2-1-1 among all other examined species in this study. The epigynal structure of this species is also prominently different from the simple composition in other Oedothorax species by having a knob on each side of the ventral plate and the long slits on the ventral plate of the epigyne. Therefore, this species does not belong to Oedothorax, and its relationship to other erigonines remains unknown.
