Description of Glaucolepis flagellata Remeikis & Stonis , sp. nov.

( Figs 27 , 38 , 41 , 51 )

Neotrifurcula SPECIMEN RH2; IN VAN NIEUKERKEN et al. 2016B: 44, FIgS 111–114.

Type material. Holotype: ♂, CHILE, Valdivia , 20 km S Valdivia, Rincon de la Piedra, caught around Podocarpus salignus D. Don , elevation ca . 180 m, 15.xi.1981, E. S. Nielsen & O. Karsholt, genitalia slide no. RA370♂ (ZMUC).

Paratypes: 5 ♂, 3 ♀, same label data as holotype, caught around Podocarpus salignus , genitalia slide nos RA 322♂, RA 326♂, RA 327♀, RA 591♀ ( ZMUC).

Diagnosis. The combination of a uniform grey-brown forewing, large cluster of spines near phallotrema in the male genitalia, and 6.5 coils of the ductus spermathecae in the female genitalia distinguishes G. flagellata sp. nov. from all congeneric species, including the most similar G. pseudoflagella sp. nov. The species belongs to the Glaucolepis flagellata group.

Male ( Fig. 51 ). Forewing length 2.7–3.1 mm; wingspan 5.9–6.8 mm. Head: palpi cream to brownish cream; frontal tuft pale, yellowish orange; collar comprised of piliform scales, yellowish orange; scape golden cream to silvery shiny; antenna as half the length of forewing or slightly longer; flagellum with 42–44 segments, glossy, pale brownish grey to brownish cream on upper side and underside. Thorax and tegula glossy, dark grey-brown proximally, pale grey distally. Forewing glossy, densely speckled with dark brown (in other angle of view, greybrown) scales, without fascia but with distinctive bluish iridescence (only sometimes iridescence is weak); fringe dark grey to pale brownish grey; underside of forewing grey-brown or grey, without spots or androconia. Hindwing relatively wide, brown-grey to brownish cream on upper side and underside, without androconia; fringe brownish cream. Legs brownish cream, glossy on upper side and underside, except for fuscous grey forelegs on upper side. Abdomen fuscous grey on upper side, grey, shiny on underside; anal tufts cream to grey, very short, indistinctive; genital plates cream.

Female. Flagellum with about 38 segments. Otherwise as in male.

Male genitalia ( Figs 27 , 38 ). Capsule 390–470 µm long, 250–260 µm wide. Valva ( Fig. 38 ) 220–225 µm long. Juxta thickened, bifid ( Fig. 38 ). Phallus ( Fig. 27 ) 270–400 µm long, 100–130 µm wide; spines form a distinctive cluster near phallotrema ( Fig. 27 ); rod-like sclerite (“flagellum” which actually represents an enlarged cornutus) about 270 µm long.

Female genitalia ( Fig. 41 ). Total length about 1175 µm. Anterior apophyses very short. Vestibulum with a complex vaginal sclerite ( Fig. 41 ). Corpus bursae with two reticulate signa but without pectinations. Accessory sac absent; ductus spermathecae with 6.5 coils.

Bionomics. Host plant: Unknown. Adults fly in November.

Distribution. This species occurs in the southern Andes ( Chile) in the Valdivian forest habitat at an altitude of about 180 m.

Etymology. The species name is derived from Latin flagellatus (flagellated) in reference to the long sclerite (“flagellum”) in the male genitalia.
