Taxonomic history. This species was previously treated as A. atizies (Cardoso 1949), A. aepitus aepitus (Kesselring & Ebert [1982]) and A. aepitus (Brown Jr & Freitas 2000; Freitas et al. 2016) in studies conducted in the Atlantic Forest.

Diagnosis. Artines litoralis sp. nov. is externally similar to the other species of the “ aepitus group”, differing in the following combination of characters: harpe with ventral process triangular and shorter than tegumen; aedeagus longer than valva; proximo-lateral projections of lamella postvaginalis triangular and not bilobed; occurrence restricted to the Brazilian coast, from Paraíba to Espírito Santo.

Description. Male (10A–B). Head: antenna with nudum bearing12 segments.

Forewing length: 12–15 mm.

Dorsal forewing (Fig. 10A): apical spots generally absent; discal spots reduced or absent; spot in CuA 2 –2A absent or represented by a few scales.

Ventral forewing (Fig. 10B): three reduced blue to white apical spots; discal spots as in the other species, but smaller.

Ventral hind wing (Fig. 10B): apical portion of discal cell with few yellow scales; central black spot rectangular, wider than long.

Genitalia (Figs 32 A–L, 45): tegumen more or less quadrate, with proximal margin straight and distal margin convex, slightly rounded (Fig. 32C), in lateral view, shorter than length of gnathos; ventral arm of tegumen longer than dorsal arm of saccus (Fig. 32A). Saccus as long as tegumen+uncus, base shorter than lateral margin (Fig. 32B). Uncus, in dorsal view, rectangular, twice longer than wide, as long as tegumen and without disto-lateral projections, distal margin rounded (Fig. 32C). Gnathos as in the other species of the group (Fig. 32A, D). Valva twice longer than wide; sacculus triangular reaching 1/2 width of valva; costa narrow and contiguous with ampulla; ampulla elongated and shorter than costa; ventral process of harpe short and triangular, shorter than tegumen and slightly longer than dorsal process, with apical setae thin and long; dorsal process of harpe on distal 1/2, rounded in dorsal view and wider than ventral process (Fig. 32 E–F). Aedeagus longer than valva, moderately curved dorsally; ventral projection distally wide, in lateral view slightly curved ventrally (Fig. 32 G–J); cornutus similar to A. delfos sp. nov. but narrower and less corrugated (Fig. 45).

Female (Fig. 10 C–D). Forewing length: 13–14 mm. Similar to male, differing in the more conspicuous marks on dorsal forewing.

Genitalia (Figs 57 A–B, 69): tergum VIII with complete spiracular opening. Sterigma triangular; lamella antevaginalis with proximo-ventral folds elongated; lamella postvaginalis without lateral fold, with distal projections wider than in A. aepitus and separated medially by narrow and shallow indentation, proximo-lateral projections triangular and not bilobed. Ostium narrow, surrounded by membranous areas; ductus bursae without sclerotized plates.

Variation. The central black spot on ventral hind wing is longer than wide in specimens from Pernambuco and Paraíba, Brazil.

Comments. Artines litoralis sp. nov. is the only species of the “ aepitus group” which occurs in the low areas of the Brazilian coast, penetrating inland along the Rio Doce Valley, in the states of Espírito Santo and Minas Gerais. The farthest record from the coast is Paraopeba, Minas Gerais. There the species is potentially sympatric with A. liege sp. nov., from which it can be easily distinguished by the male and female genitalia.

Geographic distribution. (Fig. 79). The species is restricted to the Atlantic Forest. BRAZIL— Paraíba: João Pessoa. Pernambuco: Camaragibe, Recife, São Lourenço da Mata. Alagoas: Maceió. Espírito Santo: Baixo Guandu, Conceição da Barra, Itaguaçu, Linhares, Santa Teresa (Brown Jr & Freitas 2000).

Temporal distribution. This species occurs throughout the year, except in November.

Host plant. Unknown.

Etymology. This species is named in reference of its distribution along the Brazilian coast.
