(no genus) bipunctata; Beattie, 1976. Rhop. Direct., p. 96.

Taxonomic history. Artines bipunctata was described by Mielke (1968) based on seven specimens (one male and six females) from Jardim Zoológico, Brasília, Distrito Federal, Brazil and one male from Barbacena, Minas Gerais, Brazil. The other authors mentioned this species in taxonomic comments, faunistic studies and catalogs.

Diagnosis. Artines bipunctata differs from other species of the genus in the following combination of characters: dorsal forewing with large and semi-hyaline discal spots; ventral hind wing with discal area pale brown, without central black spot and a violet postdiscal band; male with brand; uncus wide and distally bifid; gnathos arms distally curved inward; valva distally rounded; harpe simple and not fused with ampulla; ventral projection of aedeagus wide and parallel to aedeagus, distal end bilobed, with rounded lobes bearing numerous spines; vesica entirely membranous, with very small and dispersed spines; fultura inferior laterally straight, proximal end bifid; sterigma partially sclerotized; lamella postvaginalis bifid and without lateral folds; region between seventh sternite and lamella antevaginalis completely membranous; ductus bursae with basal portion sclerotized; ostium wide, “D”- shaped, surrounded by sclerotized area.

Description. Male (Fig. 19 A–B). External morphology as described by Mielke (1968).

Genitalia (Fig. 41 A–J): tegumen more or less rectangular, wider than long, with short and triangular distal median projection (Fig. 41C). Saccus triangular, base shorter than lateral margin (Fig. 41B). Uncus rectangular, one and a half longer than wide, distally bifid, with rounded projections separated medially by shallow concavity (Fig. 41C). Gnathos arms distally curved inward (Fig. 41D). Valva twice longer than wide; sacculus triangular, narrow, longer than 1/2 of valva; costa rectangular and short, near median portion of valva, distally fused to ampulla; ampulla rectangular, longer than costa; harpe simple and not fused to ampulla, distal margin rounded with arched row of short and triangular spines turned inwards (Fig. 41 E–F). Aedeagus thick, longer than valva; opening of ejaculatory bulb on proximal end of aedeagus; ventral projection of aedeagus wide and parallel to aedeagus, distal end bilobed, with rounded lobes bearing numerous spines (Fig. 41 G–J). Vesica bearing small and short scattered spines (Fig. 39G).

Female (Fig 19 C–D). As described by Mielke (1968).

Genitalia (Figs 65 A–B, 77): sterigma rectangular. Tergum VIII with incomplete spiracular opening. Lamella antevaginalis wide and membranous, without proximo-ventral folds. Lamella postvaginalis with two sclerotized plates, one proximal near the ostium, the other distal with two distal lateral projections. Ostium D-shaped, surrounded by sclerotized area. Ductus bursae wide, basal portion sclerotized.

Variation. As mentioned by Mielke (1968) some specimens have a second spot/mark in the upper portion of CuA 2 –2A of the dorsal forewing, above the larger spot. The spiracular opening of tergum VIII of the female can be complete in some individuals.

Comments. Artines bipunctata shares several morphological characters with the species of the two groups considered before. For example, the presence of a brand on the male forewing and broad white and semi-hyaline spots on the forewing of both sexes are shared with the species of the “ aquilina group”. On the other hand, characters of the male and female genitalia, as wide uncus, harpe and ampulla not fused, fultura inferior with base bifid, ventral projection of the aedeagus not divergent and sterigma distally bifid, are also present in the species of the “ aepitus group”. However, the numerous and unique characters mentioned in the diagnosis above justify the inclusion of A. bipunctata in a group apart.

Geographic distribution (Fig. 80). This species is only known from islands of humid forests in the Cerrado biome. BRAZIL— Goiás: Formosa, Goianésia, Vianópolis. Distrito Federal: Brasília. Minas Gerais: Barbacena.

Temporal distribution. This species occurs throughout the year, probably with several generations.

Host plant. Unknown.

Etymology. Although omitted in the original description, the name is a reference of the two white spots on the forewing.
