Urra, Francisco, Araneda, Sebastián & Moreira, Gilson R. P., 2023, New species of Oecophoridae (Lepidoptera: Gelechioidea) from Chile, Zootaxa 5254 (2), pp. 209-230 : 212

Encolia flava Urra sp. nov.

( Figs. 3, 4 , 21, 22 , 39, 40 ).

Diagnosis. This species can easily be differentiated from Encolia campodonicoi Urra, 2017 by the yellow coloration of the wings and by the hook-shaped inferior process of the cucullus. In E. campodonicoi the FW is brown with a white blotch surrounded by a ring of black scales at the distal end of the DC and dark brown lines over veins, and the ventral process of the cucullus is stout and slightly curved in this species ( Urra 2017a). The female of E. flava lacks signum, ductus bursae is short and straight, antrum sclerotized and sterigma is sclerotized and spined.

Description

Male ( Fig 3 ). Wingspan: 17.7–19.8 mm (n = 3).

Head. Front and vertex white; flagellum of antennae, scape and pecten white; labial palpus and haustellum white ( Fig. 4 ).

Thorax. Yellow, tegulae concolorous. FW yellow, with dark brown spots on middle of DC; fringe yellow. HW yellowish white, fringe concolorous. Fore- and midlegs light grey; hindleg white; hind tibia with piliform white scales.

Abdomen. Greyish white. Terga with spiniform setae arranged in wide patches ( Fig. 22 ).

Male genitalia ( Fig. 39 ). Gnathos slightly longer than uncus, ventral surface bulged; valva longer than wide, narrower on distal third, costa with protuberance on middle section, cucullus truncate, with two processes, ventral process hook-shaped; sacculus without processes; phallus curved, 0.75 times as long as valva, apex acute ( Fig. 39b ); vesica unarmed.

Female. Color pattern similar to male. Wingspan: 17 mm (n = 1).

Female genitalia ( Fig. 40 ). Apophysis posterioris 1.2 times as long as apophysis anterioris; ostium bursae transverse; antrum slightly sclerotized; sterigma sclerotized, convex and covered by spinules; ductus bursae membranous, 4.0 times as long as corpus bursae, not spiral-shaped; corpus bursae without signum.

Distribution. Central Chile (Marga Marga, Colchagua, Talca).

Etymology. The specific epithet flava (= yellow) is a Latin adjective and refers to the color of the wings and thorax.
