Genus Sinopolycentropus Shih, Yang, Labandeira & Ren gen. n.

Type species.

Sinopolycentropus rasnitsyni Shih, Yang, Labandeira & Ren, sp. n.

Etymology.

The generic name is a combination of the prefix “Sino” for China, and a shortened version, with the infix removed, of the type genus of its referred family, " Pseudopolycentropus ". The gender is masculine.

Diagnosis.

Forewing broad and rounded, triangular in overall shape, with base of Sc merging with R; R2+R3 forking earlier than R4+R5 forking. Antennae moniliform, compact, robust and thick, multiarticulate with annulate hairs. Distinct, multiarticulate labial palps and long occipital bristles also distinguish this taxon from all previously described Pseudopolycentropodidae except for Parapolycentropus Grimaldi & Rasnitsyn 2005.

Remarks.

This genus can be assigned to the Pseudopolycentropodidae by a short Sc, simple R1, Rs with four branches, M with five branches, a dc cell present, and a simple CuA. It can be differentiated readily from all other genera of Pseudopolycentropodidae by the base of Sc merging with R, R2+R3 forking earlier than R4+R5, and moniliform antennae consisting of compact, robust, relatively short, articles with annulate hairs. Distinctive labial palps and long occipital bristles also distinguish this taxon from all previously described Pseudopolycentropodidae except for Parapolycentropus . In addition, body length of Sinopolycentropus (5.5 mm) is shorter than that of Pseudopolycentropus (6.5 to 7.5 mm), but longer than that of Parapolycentropus (3.0 mm).
