ABSTRACTIn the south and southeast of Brazil, autochthonous malaria cases can be found near Atlantic Forest fragments. The transmission is not totally clarified; thus, the behaviour of the possible vectors in those regions must be observed. An entomological and natural infection study was performed on anophelines (Diptera: Culicidae) captured in the municipalities of the mountainous region of Espírito Santo state in 2004-2005. Similarly, between the years 2014 and 2015, 12 monthly collections were performed at the permanent trapping station of the study mentioned above (Valsugana Velha, Santa Teresa, ES). Light traps with CO2 (CO2-baited Center for Disease Control [CDC] traps) were set in open areas, at the edge of the forest (canopy and ground) and inside the forest (canopy and ground), whereas Shannon traps were set on the edge of the forest. A total of 1,414 anophelines were collected from 13 species. Anopheles (Kerteszia) cruzii Dyar and Knab remained the most captured species in the CO2-baited CDC traps set in the forest canopy and was also the vector with the highest prevalence of Plasmodium vivax infection according to molecular PCR techniques. Regarding mosquitoes of the subgenus Nyssorhynchus, P. vivax was found only in abdomens, weakening the hypothesis that this subgenus also plays a role in malaria transmission in this specific region.SponsorshipEspírito Santo Research Foundation (Fundação de Amparo à Pesquisa e Inovação do Espírito Santo – FAPES).

Three new species of Nemapalpus were collected by CDC light traps in Atlantic Forest in the Brazilian state of Espírito Santo. They are described here as Nemapalpus brejetubensis, N. espiritosantensis and N. capixaba.

The life habits, behaviour, and colony structure of the cockroach Monastria biguttata were studied during 2 years in remnants of the Brazilian Atlantic forest. Monastria biguttata was abundant, conspicuous, and ubiquitous in the semideciduous forest in the north of Espirito Santo, Brazil. It was found in forest fragments of various sizes and disturbance levels, but never in the surrounding plantations. Adults and nymphs were found in colonies of 2.8–11.6 cockroaches, grasping the bark of the underside of dead trunks that were clumped on the ground, in the forest understory. The cockroaches were very sedentary, moved extremely slowly, and immediately froze when disturbed. Based on their brooding behaviour and aggregated distribution on trunks, they appeared to be gregarious with only a slow spread during nymphal development. Brood birth took place during the rainy period, and nymphs developed into adults in a minimum of 2 years. Brood size and egg number in oothecae were not very high (23.0 ± 1.5 and 31.1 ± 1.7 (mean ± SE), respectively). All these traits were analysed to understand the survival of species in forest fragments.

One of the greatest obstacles to biodiversity conservation is the lack of information to prioritize efforts on practical actions. This lack of information comes mainly from absence of inventories in many areas where few groups have reasonably complete databases. The distribution of the dragonfly fauna of Brazil is little known - only 29% of the Brazilian territory presents data about the richness of Odonata. In this contribution, a database of Odonata species of Santa Teresa Municipality was built, Espírito Santo State, Brazil. The database has 627 specimens registered, 77 species distributed in eight families and thirty-eight genera, forty of these species are common, one endemic of the State of Espírito Santo, and nineteen endemic of Brazil. In relation to the measure of conservation, four species are present in the category Insufficient Data (DD), one present in the Nearly Endangered (NT) category, three species in the Vulnerable category (VU) and one in the category In Danger (EN). Twenty-five species are considered new occurrences for the city. These results suggest that the fauna of the studied region deserves attention and points to the interest in implanting future conservation units in the region of Santa Teresa municipality.

We describe a new species of dull-colored flea-toad, genus Brachycephalus, from the Atlantic Forest of Caparaó mountains in southeastern Brazil. The new species is characterized by its diminutive size, “leptodactyliform” body, brownish color with an inverted V-shaped dark mark on dorsum, skin smooth, hyperossification and dorsal shield absent, linea masculinea absent, Fingers I and IV vestigial, Toe I externally absent, Toe II reduced but functional, Toes III and IV with pointed tips, Toe V vestigial, and ventral color uniformly brown. It is a leaf litter dweller, known only from type locality in the humid forests on the eastern slopes of Parque Nacional do Caparaó mountains, a protected area in the states of Espírito Santo and Minas Gerais, southeastern Brazil. It is the third flea-toad occurring in the state of Espírito Santo recovered as sister to all other Brachycephalus distributed from the state of São Paulo northward in the Atlantic Forest.

ABSTRACT While studying Croton material collected in Espírito Santo, we found several specimens of Croton sapiifolius, a species previously restricted to the State of Bahia. The present paper updates our knowledge about the taxonomy, habitat and geographic distribution of C. sapiifolius. This finding increases the number of known Croton species occurring in Espírito Santo State to 20 and contributes to the knowledge of Croton of the Brazilian Atlantic Forest.

The Atlantic Forest is one of two biodiversity hotspots in Brazil (Mittermeier et al. 1997, Myers et al. 2000). It is the second most diverse (Forzza et al. 2010) and threatened biome because only ca. 11.7% of the Atlantic Forest remains (Ribeiro et al. 2009). Annonaceae are well represented in the Atlantic forest with 92 species, of which 71 are endemic (Maas et al. 2015). In the State of Espírito Santo, there are 12 genera and 44 species (Maas et al. 2015). The majority of genera in Annonaceae that occur in Brazil are represented in Espírito Santo, but previously there were no records of Trigynaea Schlechtendal (1834: 328) for the State.

The genus Zachaenus Cope is the least specious within Cycloramphidae, including two species: Z. carvalhoi Izecksohn, and Z. parvulus (Girard). Both are leaf litter species distributed across Atlantic forest remnants in Southeastern Brazil. Zachaenus carvalhoi occurs westerly in the states of Espírito Santo and Minas Gerais, and Z. parvulus easterly in the states of São Paulo, Rio de Janeiro, and Espírito Santo (Verdade et al. 2009; Motta et al. 2010; Salles & Maciel 2010; Oliveira et al. 2012; Guedes et al. 2019; Frost 2019). Both species build terrestrial nests, and larval development is endotrophic nidicolous (reproductive mode 21 after Haddad & Prado 2005; Lutz 1944; Thibaudeau & Altig 1999; Zocca et al. 2014). In this work, we describe the tadpoles of Z. carvalhoi, and discuss morphological aspects regarding other endotrophic tadpoles.
