Eudaminae Mabille, 1877 (Hesperiidae), recognized as subfamily recently, is rich in Brazil. It is along the Neotropical Region where a significant part of the diversity is found, however, information that involves the biology of species is poorly yet. This paper gathers new bioecological data of an Aguna species from the municipality of Maceió (Alagoas, Brazil), close to the Environmental Protection Area of “Catolé” and “Fernão Velho”, a remnant of Atlantic Forest. Leaves containing eggs were collected in a peri-urban area (9° 33’ 26” S, 35° 46’ 36” W) and taken to laboratory to observe post-embryonic development. Larvae were also collected from another host plant in an intra-urban area (9° 39’ 40” S, 35° 41’ 58” W). The specimens were identified as Aguna megacles megacles (Mabille, 1888) and the two Fabaceae as Bauhinia pentandra (Bong.) D. Dietr. and Bauhinia monandra Kurz. from exsiccates deposited at the Herbarium. Rearing from the eggs collected on B. pentandra exposes a post-embryonic development that lasted 53.4 days for six larval instars individuals, and 46 days for the five larval instars specimen. The larvae built a shelter since the first instar and in laboratory conditions they preferred pupate on the base of the cage. This is the first report of development features for A. m. megacles, including six and five larval instars, as well as a new locality for the State of Alagoas, and two more host plants of Bauhinia suggesting specialist behavior.

AbstractThis review aims to study the main aspects of Maranhense East Mesoregion Biogeography of the state portion has suffered socio-economic and cultural changes, besides environmental conflicts due to the advance of capitalist agriculture as soy and eucalyptus agribusiness. The Maranhense East Mesoregion is formed by the union of 44cities grouped into six microregions: Chapadinha, Coelho Neto, Baixo Parnaíba Maranhense, Chapada do Alto Itapecuru, Codó, and Caxias. Historically, this mesoregion had its occupation linked to peripheral areas to the large cotton plantations of the Itapecuru and cattle creation in Pastos Bons, in the XVII and XVIII century. The economy of this mesoregion is mainly based on Eucalyptus for pulp and paper, soybean, maize, and sugarcane. It must be emphasized that the introduction of the soybean, sugarcane, the expansion of eucalyptus and the charcoal production increased the pollution of the rivers and the destruction of native resources. The lack of inspection as to legal reserve areas in rural properties and the lack of conservation units in this region may be considered as aggravating in relation to the intense expansion of agricultural activities. The vegetation of the Maranhense East Mesoregion encompasses several formations, being basically characterized by the forests of babassu and the areas of cerrado latu senso, besides the small patches of Caatinga near the border with the state of Piaui and transitional formations. The climate is typical of tropical zones, predominantly As in the Parnaíba Delta region and the Aw throughout the rest of the mesoregion, with annual average temperatures between 24°C to 28°C and precipitation index with values between 1800mm to 1000mm. The studied mesoregion has only five Conservation Unit: Mirador State Park, Morros Garapenses State Environmental Protection Area, Parnaíba Delta Environmental Protection Area, Parnaíba Delta Marine Extractive Reserve, Chapada Limpa Extractive Reserve.Keywords: Maranhão geography.

Socioeconomic aspects.CARACTERIZAÇÃO BIOGEOGRÁFICA DA MESORREGIÃO LESTE MARANHENSE (BRASIL)ResumoEsta revisão tem como objetivo estudar os principais aspectos da Biogeografia da Mesorregião Leste Maranhense, porção do estado que tem sofrido mudanças socioeconômicas e culturais, além de conflitos ambientaisdevido ao avanço da agricultura capitalista como o agronegócio da soja e eucalipto. A Mesorregião Leste Maranhense é formada pela união de 44 municípios agrupados em seis microrregiões: Chapadinha, Coelho Neto, Baixo Parnaíba Maranhense, Chapadas do Alto Itapecuru, Codó e Caxias. Historicamente, esta mesorregião teve sua ocupação ligada às áreas periféricas às grandes plantações de algodão do Itapecuru e criação de gados em Pastos Bons, no século XVII e XVIII. A economia desta mesorregião baseia-se principalmente no Eucalipto para a produção de celulose e papel, soja, milho e cana-de-açúcar. Deve-se ressaltar que a introdução da soja, da cana-de-açúcar, a expansão do eucalipto e a produção de carvão vegetal aumentaram a poluição dos rios e a destruição de recursos nativos. A falta de fiscalização quanto às áreas de reserva legal nas propriedades rurais e a falta de unidades de conservação nesta região, podem ser consideradas como agravantes em relação à expansão intensa das atividades agropecuárias. A cobertura vegetal da mesorregião Leste maranhense engloba várias formações, sendo basicamente caracterizada pelas florestas de babaçu e pelas áreas de cerrado lato senso, além das pequenas manchas de caatinga próximas à fronteira com o estado do Piauí e formações transicionais. O clima da região é característico das zonas tropicais, predominantemente As na região doDelta do Parnaíba e o Aw em todo o restante da mesorregião, com temperaturas médias anuais entre 24 °C até 28 °C e índices de precipitação pluviométrica com valores entre 1800 mm a 1000 mm. A mesorregião estudada apresenta apenas cinco Unidades de Conservação: Parque Estadual do Mirador, Área de Proteção Ambiental Estadual dos Morros Garapenses, Área de Proteção Ambiental do Delta do Parnaíba, Reserva Extrativista Marinha do Delta do Parnaíba, Reserva Extrativista de Chapada Limpa.Palavras-chave: Geografia do Maranhão. Conservação ambiental. Aspectos socioeconômicos.

AbstractThe first-instar larvae of Delia radicum (L.) and Delia antiqua (Meigen) enter host plants to feed in galleries. These galleries can be filled by a liquid resulting from the putrefaction of the host. In this study, we show that D. radicum and D. antiqua larvae have a metapneustic respiratory system in the first instar and an amphipneustic respiratory system in the second instar, as observed in the majority of cyclorrhaphous Diptera. In addition, we observed four spatulate, ramified structures on the postabdominal spiracles in all three larval instars. We propose that these structures facilitate gas exchange (CO2 and O2), especially in the first-instar larvae when they feed in liquid-filled galleries.

Ecological tourism stands out as an economic activity that can be reconciled with nature conservation. Such activities have been carried out in several conservation units in Brazil. However, for satisfactory implementation, it is necessary to effectively plan the activities to be conducted, places to be visited, and paths to reach those places. In this context, we aimed to assess whether Google Earth software can assist in the expansion of the plan to use these areas for ecotourism, especially the routes that may be taken by tourists within the conservation unit. For this purpose, tourist interest sites were defined in the State Environmental Protection Area of Rio Pandeiros in the northern region of the state of Minas Gerais. The shortest routes between the pairs of locations obtained using Google Earth and QGIS software were evaluated. Additionally, it was necessary to perform vectorization and classification of all roads in the area. The lengths of the paths obtained were compared using a method identity test. The results showed that for most routes, Google Earth showed longer paths than QGIS. It can be concluded that for the purpose of ecotourism, precise planning should consider the vectorization of roads in areas with many rural roads.

AbstractThe egg, larva, and pupa of Caurinus dectes are described and illustrated. Eggs are ellipsoidal, coated with black cement, and are attached to bryophytes. The larva is orthosomatic, with much-reduced thoracic legs, and further differs from other larval Boreidae in: amphipneustic spiracles, number of stemmata (7), placoid sensilla present in membrane of first antennal segment, and egg burster on frons in first instar. Three larval instars are recognized from analysis of head measurements and partial rearing. Larvae feed in stemmines or galleries in leafy liverworts (Jungermanniales). Pupation occurs in a silk-lined cell or cocoon, otherwise unknown in the Mecoptera; the pupa is exarate, with decticous mandibles. The seasonal occurrence of egg eclosion (February-March), pupation (July-August), and principal adult activity (October-April) is typical for the Boreidae, but only C. dectes is univoltine in this family. Successive annual generations appear to overlap through extended egg diapause and adult perenniation.

Despite the long history of embryological studies of squamates, many groups of this huge clade have received only limited attention. One such understudied group is the anguimorphs, a clade comprising morphologically and ecologically very diverse lizards. We describe several stages of embryonic development of Anguis fragilis, a limbless, viviparous anguimorph. Interestingly, in several clutches we observe high morphological variation in characters traditionally important in classifying embryos into developmental stages. The causes of this variation remain unknown but environmental factors do not seem to be very important. Additionally, we describe the state of ossification in several perinatal specimens of A. fragilis. The cranial skeleton is relatively poorly ossified around the time of birth, with all of the bones constituting the braincase unfused. On the other hand, the vertebral column is well ossified, with the neurocentral sutures closed and the neural arches fused in all postatlantal vertebrae. Such an advanced state of ossification may be related to the greater importance of the vertebral column in locomotion in limbless species than in ones with fully-developed limbs. Numerous factors seem to affect the state of ossification at the time of hatching or birth in squamates, including phylogenetic position, mode of reproduction and, potentially, limblessness. However, data from a greater number of species are needed to reach firmer conclusions about the relative importance of these variables in certain clades.

Inventories of Amazon invertebrates are relatively incipient and fragmented. The state of Amapá is one of the Amazonian states with a large knowledge gap regarding invertebrate biodiversity. Also, there is no record in the literature of systematic studies that focus mainly on the Acridofauna. Therefore the goal of this study was to understand the diversity and abundance of grasshoppers (Gomphocerinae) of the Environmental Protection Area of the Curiaú river, Macapá - AP. Twelve samples were collected from October 2011 to September 2012 using the active search technique with sweep nets. A total of 508 Gomphocerinae individuals were sampled and classified into five genera and twelve species. The floristic composition of sites A1 and A3, and sites A5 and A6, are considered more similar since the locusts are closely related to the vegetation. This is the first study assessing the diversity of orthopteroides in the state of Amapá. However, this pioneering study is expected to be the basis of future studies.

Abstract In Brazil, 179 bat species have been recorded to date, representing 68 genera and nine families. Few data are available on the bat fauna of the state of Maranhão, so the present study was based on a survey of the bat fauna of the Inhamum Municipal Environmental Protection Area (APA Inhamum) in the Cerrado savanna of the eastern extreme of the state. This inventory provides new records of bat species for the state of Maranhão and the Cerrado biome. A total of 31 species (four families) were collected, representing 39% of the bat species known to occur in Maranhão and 28.71% of the species described for the Cerrado. The family Phyllostomidae was the most diverse, with 23 species (74.20% of the total), and also the most abundant, with 86.09% of the specimens collected. The Molossidae (four species) was the second most diverse, followed by the Vespertilionidae (three species) and the Emballonuridae (one species). Carollia perspicillata was the most abundant species (28%).The records of Artibeus fimbriatus and Platyrrhinus fusciventris are the first for the Cerrado and were also recorded in Maranhão for the first time. The cumulative species curve did not reach an asymptote. The species Dermanura gnoma, Lasiurus blossevillii, Lasiurus ega, Micronycteris schmidtorum, Molossops temminckii, Platyrrhinus cf. recifinus, Phylloderma stenops and Trachops cirrhosus, were also recorded in Maranhão for the first time demonstrating the value of for mammal inventories and emphasizing the need for further surveys in this poorly-known region.

Conservation Units are an important tool for the Brazilian biota protection. However, various taxa, including the social wasps, are undersampled or are unknown in these areas. Therefore, our study aimed to assess the social wasp richness and distribution in the Conservation Units in Minas Gerais state, southeastern Brazil. The social wasps were sampled between 2015 and 2019 in the Ritápolis National Forest (FLONA Ritápolis), in the Alto-Montana Private Natural Heritage Reserve (RPPN Alto-Montana), in the Rio Machado Basin State Environmental Protection Area (APA Rio Machado) and in the Serra de São José Environmental Protection Area (APA Serra de São José), using two different sampling methodologies. Fourteen species were sampled for FLONA Ritápolis, 10 for RPPN Alto-Montana, 35 for APA Rio Machado and 19 for APA Serra de São José. Ninety-six social wasp species of the known richness in Minas Gerais were sampled in 14 Conservation Units, representing 90% of the fauna of the state. Thirty-four species are exclusive to these areas, with emphasis on the Rio Doce State Park, the Serra do Papagaio State Park, the Pandeiros River Wildlife Regufe and the APA Rio Machado. Most of the Conservation Units sampled are in the Atlantic Forest areas, but further efforts are needed in this biome, because of its accelerated destruction. There is still an urgent need for more studies in the Cerrado and Caatinga areas in the state, especially in Conservation Units.

Six individuals of Oxymycterus dasytrichus (Schinz, 1821) were found on the coast of Paraná and Santa Catarina (in the Atlantic Forest), expanding the known geographical distribution of the species ca. 280 km southward. The specimens represent the first record of the species for the state of Santa Catarina, and new localities to the region of southern Paraná. The identification of the species relied mainly on interspecies comparative assessment of genetic distance based on DNA sequences data from the mitochondrial cytochrome-b gene and geographic distribution of taxa across biomes, particularly in the Atlantic Forest. Our findings highlight the role of protected areas, particularly the Guaraqueçaba Environmental Protection Area, to preserve small mammals.

AbstractThe egg and larval instars of Pachybrachis peccans Suffrian and P. bivittatus Say are described and illustrated. Adults of both species appear in late May, feed on willow leaves, mate and oviposit in June–July. The larvae, unable to climb the host plants, feed in the leaf litter of dead leaves of willow; they reach the second-last or last instar by the end of the fall; then they seal their case and overwinter. Pupation occurs the following spring, probably in early May.Larval instars can be distinguished as follows: first instar with egg bursters on meso- and metathorax, with typical head chaetotaxy consisting of flattened-papillate setae and 1 pair of very long simple setae, and tibiae with 2 pairs of spiniform setae; older instars without egg bursters, and showing differences in size, in head and pronotal chaetotaxy, and in the number of spiniform setae on the tibiae.In the larvae, the premental sclerites of the head seem to be present throughout the Campsomata, a group with case-bearing larvae and not only in the Lamprosomatinae as previously reported.
