Ranjan leg. (NZCZSI) . 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. Distribution: India (Darjeeling ( Moore 1888 ), Sikkim (present study)), Burma [ Myanmar ], China , Sri Lanka ( Wang & Li 2005 ). Endotricha fuscosimilata Ranjan, N. Singh & Kirti , sp. nov. ( Figs 10 , 23 ) Type locality: Yuksom ( Sikkim , India ) Material examined: Holotype (♁). India , Sikkim : Yuksom , 20.ix.2013 (13270/H10), R . Ranjan leg. (NZCZSI). 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.
