<i>Stegosatyrus</i>, a new genus of Euptychiina from the grasslands of neotropical realm (Lepidoptera: Nymphalidae: Satyrinae)

Abstract

Three species of Pampasatyrus Hayward, 1953 (Satyrinae, Pronophilina) are transferred to Stegosatyrus n. gen. (Euptychiina) based on morphological evidence: S. imbrialis (Weeks, 1901) n. comb. from Bolivia (Cochabamba) and northern Argentina; S. ocelloides (Schaus, 1902) n. comb. from Paraguay (Hernandarias and Caaguazú) and Brazil (Midwest, Southeast and South regions); and S. periphas (Godart, [1824]) n. comb. from southern Brazil, northeastern Argentina (Buenos Aires) and Uruguay. A new species is described, Stegosatyrus hemiclara Pyrcz, Boyer & Zacca, n. sp. from the Andes of southern Peru. The neotype of Satyrus periphas Godart, [1824] and the lectotypes of Epinephele imbrialis Weeks, 1901 and Euptychia ocelloides Schaus, 1902 are designated. Redescriptions and illustrations are presented, including information on geographical and temporal distribution, and habitats. The oviposition process, eggs and first instars of S. periphas are published for the first time.

Assessment of the current state of biodiversity data for butterflies and skippers in the state of Mato Grosso, Brazil (Lepidoptera, Papilionoidea and Hesperioidea)

“…Higher and species-level taxonomy of all records were checked and updated, based on Blandin (1988), McAlpine (1971), Jenkins (1985), Jenkins (1990), Bristow (1981, 1982, 1991), Holzinger and Holzinger (1994), Tyler et al 1994, Hall (1998), Hall (2000), Willmott (2003), Lamas (2004), Bálint (2005), Hall (2005), Blandin (2007a), Hall (2007), Austin (2008), Penz (2008), Faynel et al (2012), Dolibaina et al (2013), Ortiz-Acevedo and Willmott (2013), Seraphim et al (2013), Zacca et al (2013), Dias et al (2014) and Díaz et al (2014). Collected specimens were identified through direct comparison with specimens deposited at the Coleção Entomológica Pe.…”

The “Taygetis ypthima species group” (Lepidoptera, Nymphalidae, Satyrinae): taxonomy, variation and description of a new species

“…However, further detailed morphological studies on Euptychiina are highly required to clarify the species and genera delimitations within the subtribe. As clear morphological keys are generated, several monophyletic groups are easily identified using informative synapomorphies (Freitas 2007, Freitas et al 2010, Zacca et al 2013). Nonetheless, because of this lack of information, the description of a new genus for the five species treated here would be premature.…”

“…The butterfly subtribe Euptychiina includes over 400 described species in 45 genera, being one of the most diverse groups in the subfamily Satyrinae (Lepidoptera, Nymphalidae) (Lamas 2004, Peña et al 2010, Zacca et al 2013). This group is predominantly Neotropical, but some species also occur in the Neartic region and in Southeast Asia (Peña et al 2010, Matos-Maraví et al 2013).…”

“…Several genera are polyphyletic, new species and genera are regularly described, and the delimitation of the recognized genera and species needs much effort before a better understanding on the systematics of the group emerges (e.g. Freitas and Peña 2006, Freitas et al 2011, in press, Zacca et al 2013). …”

Butterflies (Lepidoptera: Papilionoidea) of grassland areas in the Pampa biome, southern Brazil

“…The first species is considered a biological indicator for preserved grassland areas and was previously recorded in other regions of southern Brazil Dolibaina et al 2011;Giovenardi et al 2013;Zacca et al 2013). Opoptera aorsa aorsa had only been previously recorded in the north and northwestern regions of Rio Grande do Sul state (Giovenardi et al 2008(Giovenardi et al , 2013.…”
