Diagnosis. S. paniculata sp. nov. belongs to the Stigmella ruficapitella group. In the male genitalia, this new species differs from other representatives of the group in the presence of a basal set of very long, transverse cornuti ( Fig. 135 View FIGURES 130–136 ) and apically rounded valva without a conspicuous apical process ( Fig. 136 View FIGURES 130–136 ).

Male. Known from adult in pupal skin; only genitalia are preserved and desribed.

Genitalia ( Figs 133–136 View FIGURES 130–136 ) with capsule 180 µm long, 140 µm wide. Uncus with two very short, well-separated lateral lobes ( Figs 133, 134 View FIGURES 130–136 ). Gnathos U-shaped ( Fig. 133 View FIGURES 130–136 ). Valva ( Fig. 136 View FIGURES 130–136 ) about 130 µm long, with a slightly concave and heavily papillated inner lobe and rounded apex without pronounced apical process. Transtilla with long and slender sublateral processes. Vinculum with a short ventral plate and short triangular lateral lobes ( Fig. 133 View FIGURES 130–136 ). Phallus ( Figs 133, 135 View FIGURES 130–136 ) about 180 µm long, without carinae; vesica with a set of four very long, transverse cornuti basally ( Fig. 135 View FIGURES 130–136 ).

Female. Unknown.

Bionomics ( Fig. 15 View FIGURES 7–15 ). Host plant is unknown (unidentified). Larva is green, with a dark green intestine and pale, yellowish brown head ( Fig. 15 View FIGURES 7–15 ). Larvae mine in leaves in late August and possibly in September. The leaf mine is a slender, contorted gallery; in the initial part, brown-black frass fills the width of the gallery; further on, black frass is deposited in a slender central line ( Fig. 15 View FIGURES 7–15 ). Adults fly in September.

Distribution. Known from a single locality in the western Himalaya (Uttarakhand: Chamba), at the elevation of about 2600 m ( Fig. 1 View FIGURES 1–6 : wHi).

Etymology. The species name is derived from Latin panicula (a cluster), in reference to the set of four very long and slender cornuti in the male genitalia.
