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..
