Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, Jurasai miraculum sp. nov. and J. vanini sp. nov., and a new, morphologically remarkable population of J. digitusdei Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.

Two new species of Polypedilum (Asheum) (Diptera: Chironomidae: Chironominae) are described and figured as adult males, P. (A.) sofiae sp. n. collected in the states of Mato Grosso and Rondônia and P. (A.) mayrahu sp. n. collected in the state of Bahia, Brazil. In addition, the adult male of Polypedilum (Asheum) curticaudatum (Rempel) is redescribed based on material from some localities in the Brazilian Atlantic Forest and Pantanal, and its larva and pupa are described for the first time.

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.

The orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the “Centro de Endemismo Pernambuco”, northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging to Usina Serra Grande, in the states of Alagoas and Pernambuco, were surveyed using seventeen different scents as baits to attract orchid-bee males. Eight sites were established in the three preserves, where samplings were carried out using two protocols: insect netting and bait trapping. We collected 3,479 orchid-bee males belonging to 29 species during 160 hours in early October, 2012. Seven species were collected in the “Centro de Endemismo Pernambuco” for the first time. Richness proved to be one of the highest of the entire Atlantic Forest domain, and diversity in some sites, especially at ESEC Murici, revealed to be one of the highest in the Neotropics. Eulaema felipei Nemésio, 2010, a species previously recorded only at ESEC Murici, was found in no other preserve in the region and its conservation status is discussed.

Abstract The echimyid rodents of the genus Phyllomys are medium-sized arboreal spiny rats endemic to the Atlantic Forest of Brazil. The genus is currently composed of 13 species, although there are at least four other undescribed species. The ecology, zoogeography and diversity of the genus are still poorly understood. Here, we provide the first record of Phyllomys sulinus from the Brazilian state of Rio de Janeiro, based on a specimen collected in the Serra da Bocaina National Park, which extends the known geographic range of the species approximately 130 km to the northeast. At this site, P. sulinus occurred in syntopy with the cryptic Phyllomys nigrispinus. We describe the karyotype of P. nigrispinus for the first time and identify two different diploid numbers (2n=84 and 85). We also conducted a molecular analysis of the cytochrome b gene of five specimens, which we identified by phylogenetic reconstruction. Our findings reinforce the importance of molecular data, such as DNA sequences, and karyotypes for the differentiation of cryptic, syntopic species.

ABSTRACT During a fungi survey in the brazilian Atlantic Forest in São Paulo, São Paulo State, Brazil, polypores growing on decaying wood were collected and fragments of the basidiomata were used to obtain isolates in pure culture. A total of 37 isolates were obtained and 23 species were identified. Cultural features of Bjerkandera atroalba, Henningsia brasiliensis, Rigidoporus undatus, and Steccherinum reniforme were described for the first time. A total of 31 isolates were evaluated in terms of their ability to oxidize the Remazol brilliant blue R dye (RBBR) and guaiacol. The results of these tests indicate that all isolated species were associated with white rot in the wood. Laccase and peroxidase activities were detected by drop tests using solutions of α-naphthol and pyrogallol. Production of cellulases and siderophores was detected with carboxymethylcellulose (CMC) and chrome azurol S (CAS) agar, respectively.

AbstractA soldier-based key to the South American species of Heterotermes is presented. Six species are recognized: H. assu sp. n., H. convexinotatus, H. crinitus, H. longiceps, H. sulcatus and H. tenuis. H. assu sp. n., is described from the Brazilian Atlantic forest, including the imago, soldier and worker castes. H. assu is also recorded from urban areas as a pest. The imago of H. longiceps is described and illustrated for the first time. The soldiers of all species are illustrated and their known distribution mapped, with several new records.

The Brazilian Atlantic Forest is a biodiversity hotspot, and bromeliads are omnipresent in this biome. This study was aimed at characterizing both morphological and histochemical aspects of Vriesea friburgensis var. paludosa L.B. Sm. seeds. The seeds are filiform with a brown seed coat and yellowish-colored plumose appendages. Seeds are typically 4.4 mm long, 0.5 mm wide, and 1000 seeds weigh 683.8 mg. The seed coat presents phenolic compounds. Starch represents the main reserve compound in the endosperm; however, it is also present in smaller amounts in the embryo. The embryo occupies one-third of the seed and has a zone of constriction in the hypocotyl-radicle axis. The results of this work will contribute to the overall biology of V. friburgensis var. paludosa , as well as its taxonomic delimitation.

Immature stages of Scaptodera rhadamistus (Fabricius) are described for the first time along with notes on nidification and biology.  The larvae differ from other Scarabaeinae species in the structure of raster on tenth sternum with two irregular bunches of serrations ventrally one on either half.  Pupae with pronotum transverse having rounded margins resemble adults, and consist of four lateral, single caudal and single pteronotal support projection.  Adult males and females differ in coloration, structure of pronotum, presence of spine like process on mesosternum and, in the structure of male and female genitalia.
