Artines focus (misid.); O. Mielke; Carneiro & Casagrande, 2010. Biota Neotrop. 10 (4): 296.

Taxonomic history. In its only record in the literature this species was misinterpreted as A. focus (Mielke et al. 2010) .

Diagnosis. Artines cofus sp. nov. differs from the other species of the “ aquilina group” in the following characters: uncus distally wide and without ventral projection; aedeagus with proximal end narrow; opening of ejaculatory bulb separated from proximal margin of aedeagus by short distance; ventral projection of aedeagus with distal portion bifid; lamella postvaginalis without proximal plate, distal plate with sclerotized median notch on proximal margin and a small median projection on distal margin.

Description. Male (Fig. 17 A–B). Head: antenna with nudum bearing12 segments.

Forewing length: 11.5–13 mm.

Dorsal forewing (Fig. 17A): apical spots absent or one or two in R 3 –R 4 and R 4 –R 5; discal spots reduced and spot in CuA 2 –2A absent or vestigial; brand shorter, lower projection slightly longer than A. aquilina (Fig. 24).

Ventral forewing (Fig. 17B): three to four reduced apical spots; discal spots as on dorsal surface; submarginal band conspicuous and almost discontinued at the middle of cells; weak spot white and diffuse in CuA 2 –2A.

Ventral hind wing (Fig. 17B): apical portion of discal cell densely covered by yellow scales; central black spot large, as wide as long; postdiscal band yellow, limited distally by a not wavy dark brown stripe.

Genitalia (Figs 39 K–M, 52): tegumen more or less quadrate, distal margin convex (Fig. 39C), in lateral view rectangular, dorsal margin slightly convex (Fig. 39A). Saccus narrow medially, anterior portion slightly dilated and narrower than tegumen, proximal margin rounded (Fig. 39B). Uncus shorter than tegumen, proximal 1/2 with lateral margins convex, distal 1/2 narrow, lateral margins concave, distal portion rounded (Fig. 39C), apex curved ventrally (Fig. 39A). Gnathos reaching 1/2 length of uncus, arms parallel, slightly divergent on apex in ventral view (Fig. 39D), curved upwards toward distal end of uncus (Fig. 39A). Valva two and a half times longer than wide; sacculus short and triangular separated from harpe by long distance; costa narrow, triangular, short, projected inwards and separated from ampulla by distance longer than its length; harpe longer than 1/2 of valva, uniformly narrow; ampulla 1/2 width of harpe, not protruding; distal projection of harpe, in dorsal view, weakly curved inwards and with small distal spines (Fig. 39 E–F). Aedeagus as in A. focus, differing in the opening of the ejaculatory bulb more distant from proximal margin; ventral projection with distal lobes asymmetrical (Fig. 39 G–J). Cornutus similar to A. focus, however, spines less conspicuous and less numerous (Figs 39M, 52). Fultura inferior, in lateral view, uniformly narrow (Fig. 39L).

Female (Fig. 17 C–D). Forewing length: 12 mm. Similar to male.

Genitalia (Figs 64 A–B, 76): lamella antevaginalis narrow; lamella postvaginalis without proximal plate, distal plate with sclerotized median notch on proximal margin, distal margin with small median projection. Ostium on proximal 1/2 do sterigma; ductus bursae narrow.

Variation. The central black spot on ventral hind wing is sometimes rectangular.

Comments. Wing pattern, male and female genitalia as in A. focus, differing in the smaller size, reduced white spots on forewing, absence of ventral projection of uncus and narrower valva.

Geographic distribution (Fig. 80). This species occurs in the western Amazon Rainforest. PERU— Madre de Díos: Puerto Maldonado. San Martin: Sacanche. BRAZIL— Acre: Santa Rosa do Purus. Rondônia: Ouro Preto do Oeste.

Temporal distribution. This species occurs between August and October.

Host plant. Unknown.

Etymology. The name is an anagram of focus, the closest species of A. cofus sp. nov. .
