Diškusand A. Navickaitė, genitalia slide no. AD484 ( ZIN).   Diagnosis.  S. latilobata sp. nov.belongs to the  Stigmella ruficapitella( sensu lato) or  S. hemargyrella( sensu stricto) group. In the male genitalia, this new species differs from other representatives of the group in the combina-tion of a long vinculum ( Fig. 130) and a unique set of cornuti ( Fig. 132).  Male( Fig. 38). Forewing length 2.0 mm; wingspan 4.5 mm(n = 1).  Head.Palpi yellowish cream; frontal tuft bright ochreous orange; collar yellowish cream; scape glossy, yellowish cream; antenna one half the length of forewing; flagellum blackish brown with some purple iridescence on upper side and underside.  Thorax.Tegula, thorax and forewing dark coppery brown, with some golden gloss and purple iridescence; fascia postmedian, wide, golden shiny; fringe brown; forewing underside dark brown, without spots or androconia. Hindwing brown on upper side and underside, without androconia; fringe brown. Legs glossy, yellowish cream, covered with dark grey-brown scales with purple iridescence on upper side.  Genitalia( Figs 130–132) with capsule 170 µmlong, 105 µmwide. Uncus with two well-separated lateral lobes ( Figs 130, 131). Gnathos U-shaped, with weakly chitinized caudal processes ( Fig. 131). Valva ( Fig. 130) about 80 µmlong, with a straight inner lobe and slender apical process. Transtilla with large, distally splitted sublateral pro-cesses ( Fig. 131). Vinculum very large, one half the length of capsule or little longer, with very shallow excavation anteriorly ( Fig. 130). Phallus ( Fig. 132) about 125 µmlong, without carinae; vesica with a large, basally curved cluster of spine-like cornuti and a group of three–four very large cornuti apically.  Female. Unknown.  Bionomics( Fig. 14). Host plant is unknown (unidentified). Larva is pale green, with a green intestine and pale brown head ( Fig. 14). Larvae mine in leaves in August. The leaf mine is a slender sinuous or contorted gallery; in the initial part, black to brown-black frass fills the width of the gallery; further on, brown-black to brown frass is deposited in a wide central line ( Fig. 14). Adults fly in late August.   Distribution.Known from two localities in the western Himalaya ( Uttarakhand: Chamba and Mussoorie), at the elevation of about 2500–2600 m( Fig. 1: wHi).   Etymology.The species name is derived from Latin latus(wide) combined with Latin lobatus(lobed), in reference to the large ventral lobe of the vinculum in the male genitalia. 2985231353 2010-08-23 ZIN A.
