‘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.
