( Figs 9 View FIGURES 9 – 11 , 12 View FIGURES 12 – 18 , 34 View FIGURE 34 , 37 View FIGURE 37 , 40–42 View FIGURES 38 – 42 )

Type material. Holotype: ♂, PERU, Dept. Ayacucho, 25 km W Puquio, Senal Cerro Palmaderas , 3370 m, 10– 12.iii.1987, O. Karsholt, genitalia slide no. Diškus 197♂ ( ZMUC) .

Diagnosis. This rather large, externally speckled, in male genitalia highly peculiar species differs from other known Stigmella by the combination of a U-shaped gnathos, distictly bilobed uncus and specific apical clusters of spine-like cornuti.

Male ( Fig. 34 View FIGURE 34 ). Forewing length about 3.6 mm; wingspan about 7.6 mm. Head: palpi grey cream; frontal tuft pale orange, fuscous brown on frons; collar cream; scape cream with some brown scales; antenna longer than half the length of forewing; flagellum with 41 segments, grey to grey-brown on upper side and underside, glossy. Thorax and tegula cream, densely speckled with brown brown scales. Forewing cream to silvery cream, irregularly speckled with pale brown to dark brown scales without purple or blue iridescence; at certain angle of view, forewing looks brown irrorated with greyish white scales; fringe pale brown; underside of forewing grey-brown, with no spots. Hindwing and its fringe pale brown on upper side and underside, with no spots or androconia. Legs fuscous brown on uppr side, silvery cream on underside.

Female. Unknown.

Male genitalia ( Figs 40–42 View FIGURES 38 – 42 ). Capsule longer (305 µm) than wide (220 µm). Uncus bilobed. Gnathos U-shaped ( Fig. 42 View FIGURES 38 – 42 ). Valva 205–210 µm long, 40–50 µm wide, with two very short apical processes; transtilla with short sublateral processes. Juxta absent or indistictive. Vinculum with short, slender lateral lobes. Phallus ( Fig. 41 View FIGURES 38 – 42 ) 220 µm long, 70–85 µm wide; vesica with two distinctive apical clusters of spine-like cornuti.

Bionomics Adults fly in March. Otherwise biology unknown.

Distribution ( Fig. 9 View FIGURES 9 – 11 ). This species occurs in the Peruvian Andes ( Peru: Ayacucho Departamento) at altitudes about 3370 m ( Fig. 12 View FIGURES 12 – 18 ).

Etymology. The species name is derived from Latin sparsus (mottled, speckled) in reference to the distinctly speckled moth (the densely irrorated thorax, tegula and forewing).
