Quadraticossus fangi Wang & Ren, 2007 (Fig. 3) 2007 Quadraticossus Wang Y & Ren, p. 41. figure 1 (A–F) Remarks. This species was erected based on both complete forewings and hind wings (Wang & Ren, 2007a). After re-examining part and counterpart of the holotype, we have reconstructed the hind wing of Q. fangi (Fig. 3). Sc and R are similar to those of Q. eumorphus: Sc parallel with R at base, fused with R at point of origin of Rs, then confluent with R1+2 for short interval, then extended to costal margin at indentation.
