Diagnosis. Artines delfos sp. nov. differs from the other species of the “ aepitus group” in the following combination of characters: valva three times longer than wide; harpe with ventral process wide, shorter than tegumen+uncus, distal 1/3 angular; dorsal process of harpe over proximal 1/2 and distally directed ventrally.

Description. Male ( Fig. 8 A–B). Head: antenna with nudum bearing 12 segments.

Forewing length: 14 mm.

Dorsal forewing ( Fig. 8A ): two apical spots reduced to few scales; discal spot in M 3 –CuA 1 slightly arched; spot in CuA 2 –2A absent.

Ventral forewing ( Fig. 8B ): a row of four blue apical spots directed toward median portion of outer margin.

Ventral hind wing ( Fig. 8B ): apical portion of discal cell with few yellow scales; central black spot rectangular, longer than wide.

Genitalia ( Figs 30 A–L, 44): tegumen more or less rectangular, with proximal margin concave and the distal margin not conspicuous ( Fig. 30C ), in lateral view shorter than length of gnathos; ventral arm of tegumen longer than dorsal arm of saccus ( Fig. 30A ). Saccus shorter than tegumen+uncus, base same size as lateral margin ( Fig. 30B ). Uncus, in dorsal view, rectangular, about twice longer than wide, longer than tegumen, without disto-lateral projections, distal margin rounded ( Fig. 30C ). Gnathos as in the other species of the group ( Fig. 30A, D ). Valva three times longer than wide; sacculus triangular and more than 1/2 width of valva; costa narrow and contiguous with ampulla; ampulla irregular and shorter than costa; ventral process of harpe wide, as long as tegumen, distal 1/3 angular, with apical setae thick and long; dorsal process of harpe on proximal 1/2, narrower than ventral process, with apex over dorsal margin of ventral process ( Fig. 30 E–F). Aedeagus shorter than valva, slightly curved dorsally; ventral projection as in A. aepitus ( Fig. 30 G–J); posterior end of cornutus triangular, with distal spines thin and curved laterally ( Fig. 44 ).

Female. Unknown.

Variation. Not observed.

Comments. Artines delfos sp. nov. is apparently rare or rarely collected. The male genitalia are similar to A. rica and A. liege sp. nov., differing in the ventral process of harpe wider and not cylindrical.

Geographic distribution ( Fig. 78 ). The species is known only from the type locality. BRAZIL— Amazonas: Maués.

Temporal distribution. This species occurs in February.

Host plant. Unknown.

Etymology. Delfos is a Greek city that the ancient Greeks believed to be the center of the universe. The name of the species is in reference to its central geographic distribution in relation to the other species of Artines . The name is a noun in apposition.

Type material. Holotype male deposited at the OM–DZUP with the following labels: / HOLOTYPUS / 1– 15.III.2008, Rio Preto , Maués, Amazonas, [ Brazil], [no collector] / gen. prep. A. Medeiros 2018 / OM 70.129 / Holotypus Artines delfos Medeiros & Casagrande det. 2018 /.
