Lamas det. ‘92 [unpublished] / LECTOTYPE Hamearis guayapensis Giacomelli, 1911 Callaghan & Kaminski det. 2017/ (MLPA). The characteristic lectotype label will be sent to the curator of the collection.
Diagnosis. Forewing length: males 10.5–11.0 mm (n = 10), females 12.1 mm (n = 3).
Sertania guttata comb. nov. appears at first glance as a small Aricoris with white spots much like sympatric Aricoris signata (Stichel, 1910), but can be easily distinguished by the scalloped distal margin of the FW and the lacking of the spot at the base of the HW cell Sc + R1. Differences with the additional species in the genus are discussed in following sections.
Variation. This species shows some variation between and within populations regarding the extent of yelloworange scaling on both wings.
Biology and distribution. The type locality of Sertania guttata comb. nov. in Mendoza and some distribution records in La Rioja (Argentina) correspond to xeric habitats, known as Monte vegetation (Fig. 34), part of a warm shrub desert at the east of the Andean mountains (Giacomelli 1911, Roig-Juñent et al. 2001). Most of the additional records are from Chaco vegetation formations in lowlands and mountain areas of “chaco serrano” (Fig. 35), but never above 1500 m. Adult habits are sedentary and males were observed perching for long periods with closed wings on low bushes or on the ground. In consecutive visits, different males are found in the same places in an apparent territorial behavior (Figs 39–40). Females were encountered nectaring on flowers with wings spread. The range of S. guttata comb. nov. includes central and western Argentina in the Provinces of Catamarca, Cordoba, Formosa, La Rioja, Mendoza, Salta and Santiago del Estero (Volkmann & Nuñez-Bustos 2010, Nuñez-Bustos & Volkmann 2013). In western Paraguay, it is recorded in Chaco areas (Drechsel 2016) and although it should occur in similar habitats in Bolivia (Jauffret et al. 2008) its presence there has yet to be confirmed.
