Bálint, Zs.: Arcas Swainson, 1832 is revisited: review of some species-group names, identification of the sister group and a key for species (Lepidoptera, Lycaenidae: Eumaeini)

Material examined - COLOMBIA: Bogota (2 males, 1 female, MNHN); Muzo, Ap. Maria (2 males, 1 female, MNHN); Muzo, 4-800 m, coll. Fassl, ex coll. Brabant (1 female, MNHN); Muzo (1 male, MNHN); no precise locality (1 female, MNHN). Remarks -NlCOLAY (1971) indicated a single A. delphia record from Colombia ("Victoria, Caldas", SCHMIDT-MUMM collection, Bogota). Beside the BMNH specimen originating from the type locality (see BÁLINT 2002), I could find the above listed 5 male and 4 female specimens under the names "Thecla paphia" or "Thecla tuneta" in the MNHN FOURNIER collection. Areas katia is considered as junior subjective synonym of A. delphia in the CNB without any support (ROBBINS 2004). According to the documentation and description of A. katia, the two taxa indeed seem to be synonymous, as their holotypes have an identical tiny fore wing dorsal scent patch "lying completely outside the cell, well beyond transverse line" (= discocellular veins), "longer hind wing" and "much reduced dark margins on the upper hind wing" compared to tuneta (NlCOLAY 1971). Therefore, I formalise here the synonymy as Areas delphia NlCOLAY, 1971 = Areas katia JOHNSON et SALAZAR, 2002, syn. n. Examining A. delphia female material, I observed that the fore wing ventrum possesses a faint submedial pattern which appears in most of the specimens I examined as a light band. It is obvious in the "A. delphia ? V" figure of d'ABRERA (1995: 1105). This character was omitted by NlCOLAY (1971), who gave an illustration of a specimen as A. delphia female without this pattern. It is questionable whether the specimen depicted as A. delphia female by NlCOLAY (1971: 102, fig. 8c-d) represents indeed A. delphia or actually it is the female of the species for which the name "Thecla splendor" was misapplied (see below). Areas splendor (DRUCE, 1907) NlCOLAY, 1971 (Fig. 11) Thecla splendor DRUCE, 1907: 570, PI. 31, fig. 4 (holotype dorsum and ventrum). Areas splendor (DRUCE); NlCOLAY 1971, female: 105, fig. 5b (genitalia), 9c (dorsum), 9d (ventrum); BÁLINT 2002: 154, fig. 24 (holotype dorsum), 25 (holotype ventrum), 26 (holotype labels), 27 (male dorsum), 28 (male ventrum). Areas nicolayi SALAZAR et COSTANTINO 1995a: 125; ROBBINS 2004: 119 (as A. splendor new synonym with no support); syn. n. Areas lecromi SALAZAR et COSTANTINO, 1995Ö: 461; BÁLINT 2002: 159, fig. 29 (male dorsum), 30 (male ventrum); ROBBINS 2004: 119 (as A. splendor new synonym with no support); syn. n. Remarks - The CNB indicates that taxa of A. lecromi and A. nicolayi are synonyms (ROBBINS 2004). Evidence has not been presented. The holotype of A. nicolayi was presented in a figure in the original description. Photographic docu-
