Diagnosis:
Endotricha similata
is closely similar to
E. dumalis
, the diagnosis is discussed under the latter. Another closely similar species to
E. similata
is the new species described hereafter. Diagnosis is discussed under the new species.

Paratype
. 1 ♁ (13271/H10), data same as holotype.
Diagnosis:
Morphologically,
E. fuscosimilata
sp. nov.
(
Fig. 10
) is closely similar to
E. similata
but is fuscous in colour, and the wing markings are less expressive. In male genitalia, the apico-lateral lobes of uncus are less produced and almost straight, gnathos apically narrower and more oval, socii larger, phallus larger, more robust (whereas in
E. similata
, the apico-lateral lobes of uncus are more produced and curved, gnathos apically rounded, socii are comparatively shorter).
Description:
Male. Forewing length
9 mm
. Labial palpi upturned, reaching up to vertex of head. Antenna basally swollen with a bunch of scales arising from basal segment. Forewing with some rusty scales on fuscous ground colour; costa fuscous beyond middle, spotted with white; subcostal area beyond antemedial curved line with rusty brown scales; outer area having pinkish scales. Underside with discocellular spot conspicuous. Hindwing with inner and outer area speckled with rusty pink scales posterior to median nervure.
Male genitalia with uncus ‘T’-shaped, having apico-lateral arms almost straight, socii upwardly directed. Gnathos apically rounded. Dorsal portion of valva membranous, inner wall bearing anteriorly directed long setae; costal band pronounced, sclerotised, ventral valva edge convexly curved in ‘C’-shape; sacculus broad at base, saccular process robust and broad medially, approximately 1/4
th
length of valva, apex pointed. Tegumen broad, as long as uncus. Transtilla sclerotised and basally broad. Juxta elongate tongue-shaped, apical half ornamented with small spines. Vinculum longer than tegumen, notched ‘U’-shaped anteriorly. Phallus as long as the width of the whole apparatus, apodeme largely sclerotised, cornutus absent.
Female unknown.
Distribution:
So far, the new species is only known from its
type
locality i.e.,
Sikkim
.
Etymology:
The species epithet refers to its more fuscous appearance than the closely similar species
E. similata
, meaning “a fuscous
similata
”. A noun in the nominative singular standing in apposition to the generic name.
