Taxonomy from Fossilworks.com.
Diagnosis for the genus from Yang et al. 2012, p. 4: 'Large neuropterans (forewing 50–75 mm long) with the following character states: labial palpi stout, relatively short; antennae stout, filiform, apparently much shorter than forewing length; two tibial spurs straight, shorter than basitarsus; claws big, strongly curved; in both wing, humeral veinlet well-developed, strongly recurrent, branched; presumed ScA short, fused with ScP within humeral area; membrane covered with dense, long hairs; RA (or ScP+RA) entering margin well before wing apex; subcostal crossveins numerous; radial crossveins irregularly spaced, not forming gradate series; in the forewing, MP, CuA, CuP dichotomously branched; presumed AA1+2 very short (found in Parakseneura gen. nov.); AA3+4, AP1+2, AP3+4 deeply forked; in hind wing, presumed AA1+2 very short (found in Pseudorapisma gen. nov.); proximal half of hind wings considerably wider than distal.'
Determined by Dr. V. Makarkin, Academy of Sciences Vladivostok, Russia, as Paraksneura sp.
It might be P. albadelta.
