Handlirsch:607. Pterinoblattina Scudder; Martynova: 279 Type species. Pterinoblatinna pluma (Giebel), by subsequent designation by Handlirsch, 1906: 607. Discussion. Pterinoblattina was described by Scudder as a genus of Blattodea (cockroaches) but was transferred to the Neuroptera by Handlirsch (1906). This was followed by Martynova (1962) who placed the genus in the family Brongniartiellidae. Scudder's figure of the type species (1886: pi. 22, fig. 7) is accurate and examination of the specimen shows that the sub- costal runs close to the first radial vein, particularly towards the apex of the wing, but then appears to stop and cannot be traced further forwards. It is probable that it curves down slightly but it does not appear to fuse with the radial vein. From the evidence available the genus is best left in the Brongniartiellidae.
