Coptotriche carmencita Stonis & Diškus, sp. nov.

(Figs 23, 24, 57–62, 115–120)

Type material. Holotype: ♂, PERÚ: Junín Region, La Merced, 11 ° 04ꞌ02.7ꞌꞌS, 75 ° 20ꞌ37.7ꞌꞌW, Fundo San José, 840–900 m, at light, 8–17.v.2018, leg. J. R. Stonis & S. R. Hill, with participation of J. Puplesyte-Chambers, genitalia slide no. AD992 (ZMUC) . Paratypes: 1 ♂ (with abdomen missing), 1 ♀, same label as holotype, genitalia slide no. AD 993♀ (ZMUC) .

Diagnosis. External characters are not sufficient for species identification. In the male genitalia, the combination of a short, slender, triangular vinculum (Fig. 61), weakly developed spines on the phallus (Fig. 62), strongly spined diaphragma (Fig. 61), and a membranous, wrinkled anellus (Fig. 59) distinguishes C. carmencita from all known Coptotriche species. In the female genitalia, the combination of a bulbous accessory sac (Fig. 116), very large and elaborated ductus spermathecae (Fig. 120), and long corpus bursae (Fig. 116) distinguishes the new species from all known congeneric species.

Description. Male (Figs 23, 24). Forewing length 2.6–2.7 mm; wingspan 5.6–5.8 mm (n = 2).

Head. Face, labial palpus; frontal tuft, and collar concolorous, yellow cream to yellow-ochre; antenna distinctly longer than one-half length of forewing; flagellum glossy, greyish cream to yellow cream.

Thorax. Tegula, thorax, and forewing concolorous, glossy, ochre-yellow, sparsely speckled with grey scales, and with some purple iridescence, particularly distinct along forewing dorsum; fringe grey, with incomplete and inconspicuous fringe line, comprised of black scales; forewing underside densely covered with pale grey to dark grey scales, with slight purple iridescence, without spots or androconia. Hindwing glossy white to pale grey (depending on angle of view), without androconia; fringe ochre cream to pale grey. Legs very glossy, cream, with some grey and black grey scales on upper side.

Abdomen. Grey cream, with distinct metallic gloss on upper side, pale grey, distally yellow-ochre or whitish cream on underside; anal tufts inconspicuous, yellowish cream. Genitalia (Figs 57–62) with capsule about 365 µm long. Uncus with two very large lateral lobes (Figs 58, 60). Valva broad, undivided (Figs 58, 61), about 275 µm long (excluding the basal process); transtilla short (Fig. 57); basal process of valva short (Fig. 58). Anellus membranous, wrinkled (Fig. 59). Diaphragma spined (Fig. 61). Phallus about 515 µm long, strongly broadened in distal third, with weakly developed spines (Fig. 62).

Female. Externally similar to male.

Genitalia (Figs 115–120) about 1800 µm long. Ovipositor lobes large (Fig. 117) with short, stout and darker, modified setae (‘peg setae’) (Fig. 119); area between ovipositor lobes indistinct, with tiny papillae and some short setae. Second pair of lobes, lateral and anterior to ovipositor lobes, much smaller than ovipositor lobes, but bearing very long slender setae, without stout, modified peg setae. Posterior apophyses longer than anterior ones (Figs. 115, 116); prela comprised of three pairs of projections (Fig. 117). Corpus bursae long and narrow (Fig. 116), without pectinations or signum. Accessory sac bulbous (Fig. 116); ductus spermathaecae very large, elaborate, but without coils (Figs 116, 120); utriculus absent or not preserved.

Bionomics. The host plant is unknown. Adults occur in May, and fly to light.

Distribution. The species is known from the single locality, La Merced, Junín Region, central Peru, at an elevation of about 900 m, from the “selva alta” (Figs 19–21).

Etymology. The species name “carmencita” is a diminutive version of the feminine name Carmen. The name (instead of the correct Latin version “carmencitae”) was chosen as an arbitrary combination of letters and in honor of señora Carmen Brocq Tremolada, who realised her dream to create the Ecological Park Fundo San José and open it to the public and researchers. Jonas R. Stonis and Julia Puplesyte-Chambers are indebted to señora Carmen for her friendly welcome during our studies at Fundo San José.
