Diagnosis.
This species differs from all species of
Trogloneta
by the absence of anterior median eyes and the posteriorly pointed abdomen in both sexes (Figure 2A, B, F, G).

Remarks.
This is the only species of
Trogloneta
spider ever found living in the tropical rainforest canopy, and is also a relatively rare six-eyed mysmenid species. We have tried to collect it again in the type locality, hoping to obtain some samples for molecular study but unfortunately, more material was not found.
Distribution.
China (Yunnan).
