Type material examined. Holotype ( Figs 84 , 141 ): male, “ Nepal , Ganesh Himal | 3 km NE of Sunpati, | 2330m, 13. VI. 1993, | leg. M. Hreblay, G. Csorba ” / “Slide | ZSM Arct. | 2021- 369♂ | A. Volynkin ” ( MWM / ZSM) . Paratypes. NEPAL: 5 males, the same data as holotype ( MWM / ZSM) ; 1 male, 1 female, Solu Khumbu Himal , 10 km S of Lukla, Bupsa, 2300m, 3.vii.1993, M. Hreblay & G. Csorba leg., gen. slide Nos.: ZSM Arct. 2021 - 370♂ and 2021- 374♀ (prepared by Volynkin ) ( MWM / ZSM) ; 1 female, 2835m, Kalinchok Mt. , 6 km NNE Muldi (Murre), 27.vi.1997, M. Hreblay & K. Csak leg., gen. slide No.: ZSM Arct. 2021 - 373♀ (prepared by Volynkin ) ( MWM / ZSM) .

Additional material examined. INDIA: 1 female, Sikkim, 5.v.[18]89, J.G. Pilcher [leg.] / Rothschild Bequest, B.M. 1939-1, unique ID: NHMUK010292596 ( NHMUK) .

Diagnosis. The forewing length is 13.5–14.0 mm in males and 14.5–15.5 mm in females. Teulisna ganesha is externally reminiscent of T. pallida but distinguished by the greyish-brown body (it is pale ochreous in the congener), the considerably more intense brown suffusion on the forewing, the smaller costal spots, and the indistinct postero-lateral spot on the forewing. The male genital capsule of T. ganesha differs from T. pallida in the considerably shorter pseudoampulla and the markedly longer and distally narrower ventral lobe of the distal saccular process. The vesica of T. ganesha differs can be readily distinguished from four other species in the species-group in the longer and curved proximal ventral diverticulum, and the markedly smaller and semiglobular proximal dorsal diverticulum. Additionally, compared to T. pallida , T. ganesha has a markedly shorter medial dorsal diverticulum, a developed medial ventral diverticulum (absent in T. pallida ), and a shorter and considerably thinner cornutus on the distal dorsal diverticulum. In the female genitalia, T. ganesha differs from T. pallida in the broader ductus bursae, the markedly smaller appendix bursae lacking the dorsal sclerotised pocket, and the narrower anterior section of the corpus bursae.

Distribution. The species is currently known from Nepal ( Volynkin 2023c) and Northeast India (Sikkim) (present study).
