Diagnosis. The forewing pattern is superficially similar to many other Neotropical Archipini, especially in the genera Argyrotaenia and Furcataenia, but is not as sexually dimorphic. The venation shows similarities with Exorstaenia, Ochrotaenia, Saetotaenia and Argyrotaenia, but the combination of R 4 approximated to R 5 at base (but not stalked) in forewing, with Rs and M 1 connate, and M 3 and CuA 1 stalked in hindwing is unique.
Overall morphology of the male genitalia shows affinities with Furcataenia and Aphelia (s.s.),but the combination of characters delimits this genus as distinctive. Uncus is bifid in many Claduncaria, Cornuclepsis, some Exorstaenia, Farragona, Tacertaenia and Aphelia (s.s.), but entire in Enicotaenia. A continuous undivided transtilla is only known in Argyrotaenia group. However, the transtilla is relatively simple in most of these genera (Argyrotaenia, Ceritaenia, Exorstaenia, Farragona, Ochrotaenia, Raisapoana and Tacertaenia). A complex transtilla with a medial process is only known in Furcataenia. Variably developed lateral processes from the transtilla are found in some species of Claduncaria, Spinotaenia and Aphelia (s.s.); Enicotaenia has two dorso-lateral horn-shaped processes, which are strongly developed and serrated. Well-defined processes of the sacculus are only reported in Furcataenia and Aphelia (s.s.), but in Enicotaenia the process is smooth, single, and ventrally extended, not serrated.
The female genitalia of Enicotaenia are less informative, and no character except the presence of two lateral subconical pockets on the 8 th sternite is autapomorphic. The two depressions present in the sclerotized antrum of Aphelia (see Fig. SM1) may resemble these pockets but lack apodem-like projections. Enicotaenia does not present a cestum in the ductus bursae, as in other genera such as Clepsis, Sychnovalva, Saetotaenia or Spinotaenia. The antrum of Enicotaenia is rather simple without vestiture, similar to some species of Argyrotaenia, while it is strongly spinulated in other genera such as Furcataenia or Aphelia (s.s.). Enicotaenia has a well-developed signum with capitulum, typically Archipini, as in other related genera such as Argyrotaenia, Farragona, Furcataenia, Idolatteria and Raisapoana. Some genera present a signum as a microthorny sclerite (Chamaepsichia, Rubropsichia or Aphelia (s.s. )), or directly the signum is absent (Claduncaria, Ochrotaenia or Tacertaenia).
Description. Head: Typically tortricoid. Vertex with long scales. Frons slightly convex and covered by scales in upper part. Antennae length ca. 0.5 as long as forewing costa, dorsally scaled, ventrally ciliated, cilia less 0.5 times width of flagellomere, males with more numerous cilia than females, two rows of scales per flagellomere. Maxillary palpus undetectable. Labial palpus porrect, length (all three segments combined) same as diameter of compound eye, uniformly scaled. Proboscis well developed, naked. Ocelli and chaetosemata well developed, evident.
Thorax: Smooth-scaled including tegulae, with no tufts. Legs unmodified, male foreleg hairpencil absent. Wings with a venation typically for Archipini (Fig. 1). Forewing with a complete venation (based on one slide); M-stem absent, chorda and discal cross-vein obsolescent; discal cell ca. 0.7 times length of wing; all veins present and well defined except CuP reduced, retained only in terminal part; R 4 to costa near apex, R 5 to termen; distance between pairs of veins on termen between R 5 and CuA 1 relatively constant but distance between CuA 1 and CuA 2 slightly larger; anal veins bifurcate in basal area of wing, anal loop ca. 0.4 times length of 1A+2A; costal fold absent. Hindwing with no tubular M-stem in discal cell; vein Sc+R 1 somewhat parallel to Rs basally, length ca. 0.7 times length of wing; Rs and M 1 stalked, parallel basally, ca. 0.4 times length of wing; M 3 and CuA 1 connate; CuA 2 well developed; CuP reduced, present only in distal portion; 1A+2A sinuous, anal loop ca. 0.2 times length of 1A+2A; 3A developed. Frenulum in females with three bristles and males with one.
Male Abdomen: Segment 8 in males with lateral long brush of scales projected caudad covering genitalia. Male genitalia (Fig. 2C–D) (based on three preparations) with tegumen strongly sclerotized and developed; uncus long (length ca. 0.5 as long as valva) simple clearly differentiated from tegumen; socii weakly developed, sclerotized, with some few long seta on each lobe; arms of gnathos sclerotized, mesally fused, with short dorsal serrations; transtilla continuous, well sclerotized, ventrolaterally with paired elongate serrated processes projecting caudad; valva regular, slightly sclerotized except for the sacculus, costa concave, cucullus rounded, hairy; sacculus well sclerotized, with presence of a fine ventral tooth (digitus) ca. 2/3 length of costa; juxta fused with caulis forming a subrectangular plate; phallus with coecum penis straight, distal portion strongly curved down, dorsally minutely serrated; vesica simple, globous, with no cornuti (no cornuti sockets; no deciduous cornuti detected in female genitalia corpus bursae).
Female Abdomen: Segment 7 in females without modified scaling (corethrogyne); Female genitalia (Fig. 2E– F) (based on two preparations) typically Archipini; ostium ringlike; subrectangular sterigma, concave in middle anteriorly, slightly sclerotized on posterior edge, lamella antevaginalis with two differentiated ventral pockets and two lateral depressions (sternite 8) each internally projected in a short apodeme. Antrum short; ductus bursae approximately the length of the corpus bursae, with distinct junction between corpus bursae and ductus bursae; ductus seminalis postmedial; bulla seminalis well-defined; corpus bursae ovoid; signum well developed, elongated with the presence of interior dagger-shaped spine, length more than 0.5 width of the corpus bursae, an external capitulum well developed (one or two globular spermatophores were extracted from the corpus bursae). Anal papillae large, well developed, mesally constricted and covered by sparse long setae, posterior apophysis shorter than anterior apophysis.
Etymology. The genus name combines the related genus name Argyrotaenia with the classic Greek adjective enikós (ενικός), meaning “singular”, in reference to the unusual combination of characters present in the new genus. It is to be considered as feminine in gender.
