The antennae in both sexes are bipectinate. The hindwings have quadrifine
venation as in the preceding genera. The forewing venation is reduced by one in
the radial sector, with the distal bifurcation anterior to R5, though all three
veins branch off very close together relatively basally, and R1 emerges at that
point, just distal to the discal mark. The forewing facies is
distinctive with black and dull brown markings and suffusion on a pale, bone-coloured
ground that predominates broadly along the dorsum to the oblique postmedial. The
darker areas are marginal and a triangular medial zone. The fasciation and
discal mark are invested with pale blue iridescence.
In the male abdomen there are only tergal
apodemes on the eighth segment; these are delicate and divergent. The uncus and
scaphial setose lobes are as in
The valve expands gently to a rounded apex and has a simple central, rather
distal harpe. The saccular shield is trapezoid over its ventral margin. The
aedeagus is small, narrow, straight, without ornament.
The female has a conical ostium, long narrow ductus and a pyriform bursa that
contains a pair of stellate signa, in form not unlike those of ennomine
Inoue (type species
Graeser) is a monotypic genus from Japan, Korea and China which was suggested by
Iwata & Matsuura (1967) and Sugi (1987) to be noline on larval features rather
than sarrothripine. It has forewing facies similar to that of Dialithoptera,
but without bipectinate antennae. The male genitalia support placement in the
Nolinae, but the valve lacks a harpe and has a process at the centre of the
costa and a bifid apex. The signa in the bursa are more as in
and allies, with two closely parallel, scobinate bands. The host plant noted by
Iwata & Matsuura (1967) was Juglans (Juglandaceae).
