DIAGNOSIS. Forewing triangular oval; costal margin moderately arched, costal area with few oblique veins. Basal cell rather narrow, closed with arculus. R fork narrow, distal (level with M fork), RP nearly straight at nodal line. CuA stem bent at apex of basal cell and arched beyond it. Nodal
m-cu
bent inwards. CuA2 straight beyond nodal line. Pterostigmal area wide. Forewing dark, postnodal part with rows of small light spots.
COMPOSITION. Monobasic:

COMPARISON. Similar to
Papiliontina
gen.n.
in the R stem forked distally, the CuA stem bent at the apex of the narrow basal cell, and the costal margin moderately arched, but in the latter genus the nodal
m-cu
is feebly arched or nearly straight, and the postnodal part is more triangular, with concave festooned apical margin, without rows of light spots. In
Fletcheriana triassica
Evans, 1956
, the
type
species of the genus
Fletcheriana
(
Dunstaniidae
), the costal area is wider, with more numerous Sc branches, the R is forked much earlier (halfway from basal cell to nodal line, before M fork), the R fork and radial area are much wider, and the RP is bent stepwise at the nodal line.
