ABSTRACT
The diversity of hawkmoths (Lepidoptera: Sphingidae) is poorly known in the biomes of the Bahia state. However, studies were carried out in other states of the northeastern region with species inventories in the Atlantic Forest, Caatinga and Cerrado. In order to broaden the knowledge on of the richness and diversity of hawkmoths in the Atlantic Forest of the state of Bahia, six monthly sampling sessions were carried out in the State Ecological Station of Wenceslau Guimarães. Hawkmoths were captured using a 250-watt mercury-vapor light trap set against a white cloth panel, for two nights a month, between 6:00 p.m. and 6:00 a.m. A total of 266 specimens were collected, distributed across 17 genera and 41 species. The most abundant and dominant species were Isognathus swainsoniC. Felder, 1862, with a relative abundance of 12.41%, and Xylophanes amadis(Cramer, 1782) andXylophanes anubus(Cramer, 1777), both with 7.9%. Our study represents the second inventory of hawkmoths for the state, totaling 59 species known for the Atlantic Forest of Bahia. Isognathus excelsior(Boisduval, [1875]) and Manduca lucetius(Cramer, 1780) represented new records for the biome. The accumulated number of species indicates the need for further sampling in order to safely reach the curve asymptote.

Abstract The present paper describes a new species of Actinote (Nymphalidae, Heliconiinae, Acraeini) from southeastern Brazil, and describes the morphology of the adults and immature stages of this species. Actinote mantiqueira sp. nov. occurs in the Serra da Mantiqueira and Serra do Mar in the Atlantic Forest. Adults from this population are very similar to other species of the "orangish red mimicry complex", including Actinote alalia (C. Felder & R. Felder, 1860), its sister species, restricted to the mountains of southern Brazil. Actinote mantiqueira sp. nov. and A. alalia are distinguishable by wing pattern, male genitalia and larval morphology, and have strongly allopatric distributions. A redescription of Actinote alalia is also provided.
ABSTRACT
The Private Reserve of Natural Heritage Fazenda Lontra/Saudade (FLS), located in the Northern Coast of Bahia state, Brazil, is the largest (1,377.33 ha) preserved Atlantic Forest area between Paraguaçu and São Francisco rivers in Bahia and Sergipe, respectively. A list of 260 species belonging to six families of butterflies is presented herein, being recorded 4 species of Papilionidae, 16 of Pieridae, 29 of Lycaenidae, 41 of Riodinidae, 87 of Nymphalidae and 83 of Hesperiidae. The butterfly community was composed mainly by widespread species commonly found in open habitats. There were also many species typical of forested areas, as such Morpho telemachus richardusFruhstorfer, 1898 (Nymphalidae: Morphini), a new record to the Northeastern Brazil.
A Reserva Particular do Patrimônio Natural Fazenda Lontra/Saudade (FLS), localizada no litoral norte do estado Bahia, Brasil, corresponde a maior área (1.377,33 ha) preservada de Mata Atlântica entre os rios Paraguaçu (Bahia) e São Francisco (Sergipe). Uma lista com 260 espécies de borboletas pertencentes a seis famílias é apresentada, sendo 4 espécies de Papilionidae, 16 de Pieridae, 29 de Lycaenidae, 41 de Riodinidae, 87 de Nymphalidae e 83 de Hesperiidae. A fauna foi composta principalmente por espécies de áreas abertas com ampla distribuição geográfica. Espécies típicas de áreas florestadas também estão presentes, uma delas, Morpho telemachus richardus Fruhstorfer, 1898 (Nymphalidae: Morphini), é um registro novo para a fauna de borboletas do nordeste do Brasil.
ABSTRACT
Comprising a natural reserve with 359 ha of "montane forest" inserted on the Brazilian semi-arid, the Parque Ecológico João Vasconcelos Sobrinho (PEJVS), locally known as "Brejo dos Cavalos" is currently under high anthropogenic pressure. A list of 197 species of butterflies belonging to six families is presented, being 59 species of Hesperiidae, 4 of Papilionidae, 18 of Pieridae, 17 of Lycaenidae, 12 of Riodinidae and 87 of Nymphalidae. The butterfly community was composed mainly by widespread species commonly found in open habitats. There were also many species typical of forested areas such as Scada karschina delicata Talbot, 1932 (Danainae: Ithomiini), which is an endangered butterfly.
O Parque Ecológico João Vasconcelos Sobrinho (PEJVS), conhecido localmente como Brejo dos Cavalos, é um fragmento de "mata serrana" de 359 ha inserido no semi-árido brasileiro, e que atualmente encontra-se sobre alta pressão antrópica. Uma lista com 197 espécies de borboletas pertencentes a seis famílias é apresentada, sendo 59 espécies de Hesperiidae, 4 de Papilionidae, 18 de Pieridae, 17 de Lycaenidae, 12 de Riodinidae e 87 de Nymphalidae. A fauna é composta principalmente de espécies de áreas abertas e com ampla distribuição geográfica. Entretanto, diversas espécies típicas de áreas florestadas também estão presentes, uma delas, Scada karschina delicata Talbot, 1932 (Danainae: Ithomiini), é uma espécie de borboleta criticamente ameaçada de extinção.
