Diagnosis
ReferenceDiagnosis
O. Béthoux et al. 2002only the forewing characters are known, other parts of the body being unknown. Forewing narrow; network of irregular cross-veins covering the distal half of the wing, but variable in extension; variable irregular cross-veins between anterior margin and ScP after ScA reaches anterior margin; anterior branches of ScP long, some ramified, those of the distal half of ScP being curved towards the apex; RA posteriorly curved opposite the separation of MA and MP; the most basal anterior branchesof RAare basal to the fusion of RP with MA1; proximal part of RP very long; fusion of RP with MA1 long but variable; basal free part of MA1, basal of fusion with RP, short, shorter or equal to fusion; first branch of RP in a very distal position relative to the separation of MA1 and RP; MA1 distally ramified; MA2 posteriorly pectinate; area between MA/MA2 and MP wide; MP simple; base of MP close to the origin of CuA; area between MP and CuA + CuP1a narrow; basal free part of CuP1a twice the length of basal free part of MP before their fusion; branches of CuA + CuP1a reaching posterior margin obliquely; presence of subhorizontal cross-veins between branches of CuA + CuP1a, CuP2 and 1A.
