Treatment

Stigmella dolia Remeikis & Stonis , sp. nov.

( Figs 2 View FIGURE 2 , 4 View FIGURE 4 , 5 View FIGURE 5 , 21–24 View FIGURES 21 – 24 , 40 View FIGURES 36 – 41 )

Type material. Holotype: ♂, ARGENTINA, Neuquen, 14 km NW Confluencia Arroyo Córdoba, elevation about 740 m, 10.x.1981, Nielsen & Karsholt, genitalia slide no. RA6001 ♂ ( ZMUC) .

Diagnosis. The combination of a rounded but bilobed uncus, very large rounded sublateral processes of transtilla, the small rounded lateral lobes of vinculum, and a specific set of cornuti distinguishes S. dolia sp. nov. from all other Stigmella including the species of the S. magnispiella group (also see the pictorial key to the S. magnispinella group provided in figs 4, 5).

Male ( Fig. 40 View FIGURES 36 – 41 ). Forewing length about 3.0 mm; wingspan about 6.5 mm. Head: palpi dark brown; frontal tuft dark ferruginous brown; collar dark brown; scape silvery brown; antenna distinctly longer than half of the lenght of forewing, dark grey-brown. Thorax, tegula and forewing dark brown-grey with strong golden gloss; subapical fascia of forewing wide, silvery shiny; fringe grey-brown, silvery shiny on costa and tornus; underside of forewing dark grey-brown, without spots or androconia. Hindwing dark grey-brown on upper side and underside, without androconia or spots; fringe brownish grey. Legs shiny, fuscous on upper side, grey with some golden gloss on underside. Abdomen brown-black on upper side and underside; anal tufts short, brown; genital plates pale brown.

Female. Unknown.

Male genitalia ( Figs 21–24 View FIGURES 21 – 24 ). Capsule longer (280 µm) than wide (165 µm). Uncus rounded laterally, with two tapered caudal lobes ( Figs 21, 23 View FIGURES 21 – 24 ). Gnathos with two slender caudal processes. Valva ( Figs 21, 22 View FIGURES 21 – 24 ) 150 µm long, with slightly bulged inner lobe and two slender apical processes; transtilla with very large, lobe-like sublateral processes ( Fig. 21 View FIGURES 21 – 24 ); valvae with a basal connection. Ventral plate of vinculum with small rounded lateral lobes. Phallus ( Fig. 24 View FIGURES 21 – 24 ) 155 µm long, 40–55 µm wide; vesica with a specific set of cornuti comprised of small plate-like and spine-like cornuti, and one large horn-like cornutus ( Fig. 24 View FIGURES 21 – 24 ).

Bionomics. Adults fly in February–March. Otherwise biology unknown.

Distribution. Known from single locality in the southern Andes ( Argentina: Neuquén Province) at elavation about 740 m ( Fig. 2 View FIGURE 2 ).

Etymology. The species name is derived from Latin dolium (a large rounded vase/barrel/cask used in ancient Roman times for storage or transportation of goods) in reference to the rounded shape of capsule in the male genitalia.
