The Brazilian Atlantic Forest has a rich biodiversity increasingly threatened by human activities. Since the colonial period, the coast of the state of Bahia is among the most affected regions of Brazil by anthropic pressure. Bahia encloses Atlantic Forest remnants distributed in an area reaching 100-200 km along the east-west axis, by 1,000 km along the north-south axis, parallel to the coast of the Atlantic Ocean. We report hereafter the results of an intensive field survey of leaf litter and epigaeic ants realized in forest remnants of the Atlantic Forest landscapes within the original extension of the biome in 11 localities distributed along four degrees of latitude in the state of Bahia. In each site, 16 plots were collected using pitfall and eight using Winkler traps. We identified 391 ant species belonging to 71 genera and nine subfamilies. Among all species recorded, 21 were common to the whole 11 localities, while 98 species were recorded in a single locality. This study highlights the richness and diversity of epigaeic and leaf-litter ants living in the northern part of the Brazilian Atlantic Forest, and is one of the most representative soil ants’ inventories ever done in this biome for a single state of Brazil.

Twigs in the litter derived from the fragmentation of tree branches form one microhabitat, where entire colonies of ants, both leaf litter and arboreal species, can be found. The objective was to survey ant species that are presente in both the leaf litter and twigs simultaneously. We describe the nest type, the social structure of the colonies and the trophic guild membership of these species. Samples were collected from 10 preserved fragments of Brazilian Atlantic forest. We used Berlese funnels to collect leaf litter ants and manual collection for twig ants. We recorded 80 ant species; 60 species were in leaf litter samples and 35 species were in twigs. Of the total species, only 15 (20%) occurred simultaneously in the leaf litter and in twigs. Of these species, Gnamptogenys striatula, Pheidole sarcina, P. sospes and Solenopsis sp. 2 were the most frequent among leaf litter dwellers, and Myrmelachista catharinae was the most common arboreal species. Most of these belonged to generalista and predator guilds, with “polydomous nests” and colonies monogynous.

Composed of two main forest formations, Ombrophilous Forest and Seasonal Forest, the Brazilian Atlantic Forest biome is constituted currently by a mosaic of forest remnants and secondary vegetation. Representatives of the Ponerinae ant genus Neoponera are observed mainly in both wet and seasonally dry forests. The aim of this study was to approach the diversity of the genus Neoponera in the north of the Atlantic Forest of Brazil (from the extreme north of its distribution to the Doce River hydrographic basin in the south), associating the occurrence of ant species with the types of vegetation. We have compiled occurrence data from the collection of the Myrmecology Laboratory of the Cocoa Research Center, on internet, or available in literature. We found information on 23 species of Neoponera, including a new record for the Atlantic Forest, Neoponera globularia (Mackay & Mackay, 2010), and a new record for Brazil, Neoponera fiebrigi Forel, 1912. The relative composition of the Neoponera assemblages was evaluated according to the types of vegetation. We found that the occurrence of the genus Neoponera is mainly related to the types of vegetation of the focus region, principally dense forests where a higher diversity was observed.

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

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 orchid-bee faunas of ‘Parque Nacional do Monte Pascoal’, ‘Parque Nacional do Descobrimento’ and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were used to attract orchid-bee males. Four thousand seven hundred and sixty-four males belonging to 36 species were actively collected with insect nets during 300 hours from November, 2008 to November, 2009. Richness and diversity of orchid bees found in this study are the highest ever recorded in the Atlantic Forest domain. Eufriesea dentilabris (Mocsáry, 1897) and Eufriesea violacea (Blanchard, 1840) were collected at the ‘Parque Nacional do Monte Pascoal’, the first record of these species for the state of Bahia and the northernmost record for both species. Females Exaerete dentata (Linnaeus, 1758) were also collected at ‘Parque Nacional do Monte Pascoal’ and old records of Eufriesea aeneiventris (Mocsáry, 1896) in this area makes this site the richest and most diverse concerning its orchid-bee fauna in the entire Atlantic Forest and similar to areas in the Amazon Basin.

We present the first record of the Dipsadidae snakes Xenopholis scalaris for the state of Rio de Janeiro and a general distribution map for this species. This record for the Brazilian Atlantic Forest expands the known geographical distribution of X. scalaris and reveals that its populations might not be isolated or disjunctive, but rather rare in this biome. We also provide some recommendations for future conservation of X. scalaris.

The shining fungus beetles (Coleoptera: Staphylinidae: Scaphidiinae) comprise more than 1800 described species, which are usually small (≅0.84–14.30 mm long) (Tang et al. 2014 ; Löbl & Ogawa 2016) and found on bracket and resupinate fungi, mushrooms and slime molds (Newton 1984; Löbl & Leschen 2003; Löbl 2018). They are known to be diverse in forests of tropical and subtropical regions, which contrast to the low number of species currently known from Brazil: only 34 species and two subspecies from seven genera (Löbl 2018; von Groll & Lopes-Andrade, 2021). Any active search for Scaphidiinae in the Brazilian Atlantic forest reveals a considerable abundance and diverse of these organisms (pers. obs.), but they disperse rapidly if disturbed, and the success of field collections relies on the collectors’ skills, luck and collecting techniques and devices. The most common methods and devices for collecting shinning fungus beetles are sifting leaf litter, rotten wood and fungi, flight intercept (FIT) and V-flight intercept (V-FIT) traps, aspirators, sweeping, and hand collecting (Löbl & Leschen 2003; Tang et al. 2014; Löbl et al. 2021). Hand collecting is considered the best method, because the host fungi and larvae can be collected together to make associations (Löbl & Leschen 2003).

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.
