A DNA-based cladistic analysis con- firms that it belongs to the Euptychiina, as sister to Forsterinaria and closely related to Taygetis, Posttaygetis, Parataygetis, Pseudodebis, and Harjesia. Although immature morphology also sug- gests that this species is closely related to Forsterinaria, none of the adult morphological synapo- morphies for the genera in the aforementioned clade occur in E. pronophila, a highly autapomorphic species. Because we were unable to place it with confidence in an established genus, the monotypic satyrine genus Guaianaza Freitas & Peña New Genus is described, with Eup- tychia pronophila Butler as the type species. Key words: Atlantic forest, Forsterinaria, life history, Neotropics, Poaceae. Introduction The butterfly family Nymphalidae is composed of about 7200 species distributed through- out the world (Ackery et al. 1999). Nymphalid species exhibit a great variety of color pat- terns and morphological features, but are united by the synapomorphy of “tricarinate” antennae (Vane-Wright 2003). The Satyrinae is the most diverse subfamily within the Nymphalidae, including about 2400 species of world-wide distribution (Ackery et al. 1999). Although the Neotropical nymphalids are relatively well known, the subfamily Satyrinae remains the most poorly understood. Many species await description, many genera and tribes are not monophyletic, and there are no published phylogenetic hypothe- ses for the subfamily as a whole (Viloria & Pyrcz 1994, Viloria & Camacho 1999, Viloria 2003, Freitas 2004b, Lamas 2004).

Genus Vol. 11 (1): 69-86 Wroc³aw, 15 IV 2000 Contributions to the knowledge of Ecuadorian Pronophilini. Part IV. New taxa of Pronophila DOUBLEDAY (Lepidoptera: Nymphalidae: Satyrinae) TOMASZ W. PYRCZ Zoological Museum of Jagiellonian University, Ingardena 6, 30-060 Kraków, Poland e-mail: [email protected] ABSTRACT. Three new species and four new subspecies of Pronophila are described from Ecuador and northern Peru. The status of several taxa is revised. P. deverra THIEME, P. brennus THIEME and P. bogotensis JURRIAANSSE are regarded as subspecies of P. unifasciata; P. assarhaddon THIEME is a junior synonym of P. rosenbergi LATHY. All the species of Pronophila known to occur in Ecuador are listed and discussed. Key words: entomology, taxonomy, zoogeography, new taxa, Andes, Ecuador, Lepi- doptera, Nymphalidae, Satyrinae, Pronophila. INTRODUCTION Pronophila DOUBLEDAY (Nymphalidae, Satyrinae, Pronophilini) comprise, depending on the systematic viewpoint, between 15 and 20 species ranging from Costa Rica to northern Argentina. This is a genus that is exceptionally homog- enous as far as the wing shape and colour patterns of the adults are concerned. The wing pattern consists of a dark brown upperside, generally with a series of subapical white or orange patches extending along the veins, a series of large postmedian black ocelli pupilled with blue on the forewing underside, sometimes showing through on the upperside, and a pattern of distinct slightly lighter and darker brown bands on the hindwing underside. The differences between various taxa consist in the colour and shape of the forewing subapical patches, the number, size, colour and alignment of the forewing underside ocelli, and the 70 TOMASZ W.

The Radiation of Satyrini Butterflies (Nymphalidae: Satyrinae): A
Zoological Journal of the Linnean Society, 2011, 161, 64–87. With 8 figures The radiation of Satyrini butterflies (Nymphalidae: Satyrinae): a challenge for phylogenetic methods CARLOS PEÑA1,2*, SÖREN NYLIN1 and NIKLAS WAHLBERG1,3 1Department of Zoology, Stockholm University, 106 91 Stockholm, Sweden 2Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Av. Arenales 1256, Apartado 14-0434, Lima-14, Peru 3Laboratory of Genetics, Department of Biology, University of Turku, 20014 Turku, Finland Received 24 February 2009; accepted for publication 1 September 2009 We have inferred the most comprehensive phylogenetic hypothesis to date of butterflies in the tribe Satyrini. In order to obtain a hypothesis of relationships, we used maximum parsimony and model-based methods with 4435 bp of DNA sequences from mitochondrial and nuclear genes for 179 taxa (130 genera and eight out-groups). We estimated dates of origin and diversification for major clades, and performed a biogeographic analysis using a dispersal–vicariance framework, in order to infer a scenario of the biogeographical history of the group. We found long-branch taxa that affected the accuracy of all three methods. Moreover, different methods produced incongruent phylogenies. We found that Satyrini appeared around 42 Mya in either the Neotropical or the Eastern Palaearctic, Oriental, and/or Indo-Australian regions, and underwent a quick radiation between 32 and 24 Mya, during which time most of its component subtribes originated. Several factors might have been important for the diversification of Satyrini: the ability to feed on grasses; early habitat shift into open, non-forest habitats; and geographic bridges, which permitted dispersal over marine barriers, enabling the geographic expansions of ancestors to new environ- ments that provided opportunities for geographic differentiation, and diversification.

RES., 27(1): 1-5, 2017 1 Immature stages of the Neotropical satyrine butterfly Taygetis acuta (Nymphalidae: Euptychiina) André Victor Lucci Freitas1,2 1 Departamento de Biologia Animal, Instituto de Biologia, Universidade Estadual de Campinas, Campinas, SP, Brazil 2 Museu de Zoologia, Instituto de Biologia, Universidade Estadual de Campinas, Campinas, SP, Brazil Abstract. The present paper describes the immature stages of the Neotropical satyrine butterflyTaygetis acuta Weymer, 1910. The solitary eggs are greenish white and round. The immature stages of T. acuta are morphologically similar to those of other species of the “Taygetis virgilia (Cramer, 1776) group”, with the last instar having elongate dorsal markings resembling the yellowish- bordered, elongate blotches caused by fungus on bamboo leaves, suggesting that camouflage could be involved. The pupa is short and smooth and entirely green, with short ocular caps. Larvae passed through four solitary instars and fed on bamboo (Poaceae) offered to them in the laboratory, with the natural hostplant still unknown. Resumo. O present trabalho descreve os estágios imaturos do satiríneo Neotropical Taygetis acuta Weymer, 1910. Os ovos são branco esverdeados, arredondados e isolados. Os imaturos de T. acuta são morfologicamente similares àqueles de outras espécies do “grupo Taygetis virgilia (Cramer, 1776)”, com o último instar apresentando marcas dorsais alongadas alusivas às manchas alongadas com bordas amarelas causadas por fungos nas folhas de bambus, sugerindo que camuflagem pode estar envolvida. A pupa é curta e lisa, inteira verde, com capas oculares curtas. As larvas passam por quatro instares solitários e se alimentam em bambus (Poaceae) oferecidos em laboratório; a planta hospedeira na natureza é desconhecida.

Lycaenidae: Theclinae: Eumaeini): an Andean Montane Forest Endemic
Phylogeny, taxonomy, and sympatry of Timaeta (Lycaenidae: Theclinae: Eumaeini): an Andean montane forest endemic Robert K. Robbins & Robert C. Busby Taxonomy of the Andean lycaenid hairstreak genus Timaeta Johnson et al. and its fifteen sexually dimorphic species is detailed for the first time. Species accounts summarize nomenclature, distribution, habitat, behavior, and distinguishing traits, as well as noting why each species is considered distinct under a biological or phylogenetic species concept and how males and females were associated. An identification key for males and a nomenclatural checklist are included. Nomenclatural actions include the description of Timaeta christina Robbins & Busby sp. n., Timaeta matthewi Busby & Robbins sp. n., Timaeta walteri Busby & Robbins sp. n., Timaeta roberti Busby & Robbins sp. n., Timaeta cospata Robbins & Busby sp. n., Timaeta pilosa Robbins & Busby sp. n., Timaeta gabriela Busby & Robbins sp. n., and Timaeta romero Robbins & Busby sp. n.. Timaeta neblina (Salazar & K. Johnson, 1997) is a new synonym of Timaeta eronos (H.H. Druce, 1890). A phylogenetic analysis is based on 17 coded morphological characters and yields two most parsimonious 30-step trees. Successive weighting does not change tree topology. The node chosen to delimit Timaeta is the one that had the highest jackknife support and was most stable with past usage. Generic names Trochusinus K. Johnson, Salazar & Vélez, 1997 and Jagiello Bálint & Wojtusiak, 2000 are confirmed as synonyms of Timaeta K. Johnson, Kruse & Kroenlein, 1997. Recent revisions of primarily Andean butterfly genera have had a significant proportion of previously unnamed species, and Timaeta fits this pattern with eight of 15 species previously undescribed. Most sister lineages within Timaeta are sympatric, and more than half the species occur between 1500m and 2000m in eastern Ecuador.

PYRCZ1, HAYDON WARREN-GASH2 & ANNA ZUBEK1 1Zoological Museum of the Jagiellonian University, Ingardena 6, 30-060 Kraków, Poland, 298 Over Strand Mansions, Prince of Wales Drive, LondonSW11 4EU, corresponding author: T. PYRCZ, [email protected] ABSTRACT. Two genera of Andean satyrine butterflies,Corderopedaliodes FORSTER and Physcopedaliodes FORSTER, are reassessed based on a study of adult morphology. Their female genitalia are examined and compared for the first time and their role in providing phylogenetically valuable characters is evaluated. The male genitalia of P. physcoa (HEWITSON), the type species of Physcopedaliodes, is re-examined and shown to possess two synapomorphic characters that are unique within the diverse Pedaliodes sensu lato complex, in the form of greatly transformed pedunculus and transtilla. All the species of Corderopedaliodes and Physcopedaliodes are listed and discussed. Pedaliodes symmachus GODMAN & SALVIN, previously associated with Corderopedaliodes and Physcopedaliodes, is transferred back to Pedaliodes. Two new species of Corderopedaliodes are described from Colombia and Peru. Pedaliodes pamphos THIEME n. syn. is considered a subjective junior synonym of Pedaliodes pandates (HEWITSON), and the new subspecies C. pandates olivieri n. ssp. is described from the valley of Cosñipata in Cuzco, Peru.

Abstract: The present paper describes the immature stages and the natural history of Yphthimoides borasta. Eggs are pinkish white and round, with poorly marked hexagonal cells; the first instar is pale brown, turning dark brown with longitudinal zigzag stripes in later instars; the pupae are short, brown, without ornamentation or projections and with short, squared ocular caps. The immature stages are similar to those of other species of the genus Yphthimoides and to other representatives of the “Megisto clade”. Observed sex ratio in the field is 1:1 and adults fly in the canopy, explaining the rarity of this species in inventories and museum collections in comparison with other species of Yphthimoides.

Description of a New Species of Forsterinaria Gray from the Pantepuy (Lepidoptera: Nymphalidae: Satyrinae)
Genus Vol. 22(3): 523-530 Wrocław, 30 XI 2011 Description of a new species of Forsterinaria GRAY from the Pantepuy (Lepidoptera: Nymphalidae: Satyrinae) ANNA ZUBEK1 & TOMASZ W. PYRCZ2 Zoological Museum of the Jagiellonian University, Ingardena 6, 30-060 Kraków, Poland, 1anna_zubek@ hotmail.com; [email protected] ABSTRACT. A new species of montane butterfly,Forsterinaria hannieri n. sp. (Nympha- lidae, Satyrinae) is described from the Guyana Shield in Venezuela. It is most similar to F. inornata (C. FELDER & R. FELDER, 1867) known from western slopes of the Andes in Colombia and Ecuador, but it shows unequivocal differences, especially in the male genital morphology. Key words: Euptychiina, Forsterinaria, new species, Pantepuy, taxonomy, Venezuela. INTRODUCTION The subfamily Satyrinae (Nymphalidae) is one of the most diverse groups of but- terflies, including about 2500 species, and at least 120 genera and over 1100 species in the neotropical realm. Neotropical satyrines are generally divided into three major groups, Euptychiini, Pronophilini and Haeterini, attributed tribal or subtribal ranks depending on the author (LAMAS et al. 2004, PYRCZ 2004). Montane satyrines of the neotropical realm belong mostly to the Pronophilini (PYRCZ, 2004). The tribe Eupty- chiini, comprising 41 genera (VILORIA 2003), is mostly lowland and premontane. The only strictly montane genus of the Euptychiini is Forsterinaria GRAY (1973) which is the subject of this paper. Montane butterfly fauna of the cloud forests of the Guyana Shield in southern Venezuela, referred to by a biogeographical term of Pantepuy, can be characterized as species poor compared to the Andes but, at the same time, as rich in endemics (NEILD 2008).
