Distribution. China (Zhejiang, Fig. 24).

Remarks. The gonostylus of this species is unique by having three straight megasetae arranged strictly in one row on a very short dorsal lobe which is slightly pronounced from the gonostylus. Hippa & Vilkamaa (1991) provided a description of Prosciara without a sensory pit on the basal segment of the palpus. However, here we discovered two species with a sensory pit, P. ternidigitata and P. globoidea sp. nov. (Fig. 17 C). Since the two species show almost all the characters of Prosciara, including a characteristic dorsal lobe that bears megasetae on the gonostylus, we believe that they belong to the genus Prosciara.

Etymology. This species is named after three megasetae on the dorsal lobe on the gonostylus, from the Latin adjective ternidigitatus, meaning three megasetae.
