Material. Neotype — Specimen CNU-NX1-161, positive and negative imprints of a nearly complete insect; here designated; deposited in the Key Lab of Insect Evolution and Environmental Changes , College of Life Science , Capital Normal University ( CNU, Ren Dong, Curator; Beijing, China).

Type locality and horizon. The Late Carboniferous ( Tupo Formation ) locality near the Xiaheyan village (Zhongwei City, Ningxia Hui Autonomous Region, China) .

Description. Body: head 1.5 mm long, 1.0 mm wide; antennae filiform, with 7 segments preserved in right one; pronotum broken, estimated length 0.9 mm, estimated width 0.8 mm; mesothorax 1.3 mm long, 1.1 mm wide; metathorax 1.0 mm long, 1.1 mm wide; legs incompletely preserved; abdomen with 9 well preserved segments; a pair of cerci visible, segmented.

Right forewing: 6.7 mm long, 2.6 mm wide; ScP strong, ending on anterior margin, slightly beyond the wing midlength; area between anterior wing margin and ScP with several strong crossveins; RA simple, distinctly bent opposite the end of ScP, reaching wing apex; RP originates opposite one third of the wing length, fused with MA 0.2 mm long distal to its origin; RP + MA 0.3 mm long; RP and anterior branch of MA probably fused for a point, then separated immediately; RP with three (2, 1) or four distal branches (3, 1); M forked into MA and MP opposite the origin of RP; MA with two branches or simple; MP simple; CuA forked 0.3 mm distal to arculus; CuA1 forked 2.1 mm distal to its origin, with two branches; CuA2 forked 0.9 mm distal to its origin, with two branches; CuP simple, straight, concave; AA vein strong. Left forewing: 6.7 mm long, 2.6 mm wide; ScP strong, ending on anterior margin, slightly beyond the wing mid-length; area between anterior wing margin and ScP with several strong crossveins; RA simple, distinctly bent opposite the end of ScP, reaching wing apex; RP originates opposite one third of the wing length, fused with MA 0.2 mm long distal to its origin; RP + MA 0.1 mm long; RP with four distal branches (2, 2); M forked into MA and MP slightly before the origin of RP; MA and MP simple; CuA forked 0.4 mm distal to arculus; CuA1 forked 1.0 mm distal to its origin, with three branches (2, 1); CuA2 simple; CuP simple, straight, concave; AA vein strong and straight.

Right hind wing: poorly preserved, about 5.9 mm long, 2.4 mm wide; R divided into RA and RP nearly in wing base; RP fused with MA for 0.5 mm; M forked opposite the origin of RP.
