Distribution.
China (Shanxi, Zhejiang, Fig. 9).
Remarks.
The new species is similar to
Peyerimhoffia infera
Vilkamaa & Hippa, 2005 in the shape of the gonostylus. However, the new species can be distinguished by the three-segmented maxillary palp, the gonostylus having much inflated apex and short subapical setae (two-segmented maxillary palp, the gonostylus slightly inflated at apex and bearing long subapical setae in
Peyerimhoffia infera
).
Etymology.
This species is named in reference to its short apical lobe, from theGreek adjective brachypodus, meaning short base.
