A New Scolopocryptopid Centipede from Northeastern Brazil (Chilopoda: Scolopendromorpha)

A new species of centipede, Scolopocryptops piauhyensis sp. n., is described from Piauí State, northeastern Brazil. It is the only species in this genus known to occur in the ‘caatinga’ biome. The new species is related to S. inversus (Chamberlin, 1921) and S. ferrugineus (Linné, 1762) but differs primarily in the short, high dental plates of the coxosternum, the wider ultimate sternite, and the smaller pore field on the coxopleuron of the ultimate segment.     

A new species of <Emphasis Type="Italic">Macroptilium</Emphasis> (Benth.) Urb. (<Emphasis Type="Italic">Leguminosae</Emphasis>: <Emphasis Type="Italic">Papilionoideae</Emphasis>: <Emphasis Type="Italic">Phaseolinae</Emphasis>) from North-Eastern Brazil

Summary  A new species of Macroptilium sect. Microcochle (Benth.) J. A. Lackey is herein described from the states of Piauí and Bahia, Brazil. Macroptilium cochleatum is characterized by few-flowered inflorescences, calyx teeth longer than the tube, a tightly four-coiled keel, and linear, patent fruits. The discovery of this unique Macroptilium species, with its distally coiled keel, expands the diagnostic features of the genus. A key to the Brazilian species of sect. Microcochle is provided.     

Genetic variation and population structure of the endangered Hyacinth Macaw (<Emphasis Type="Italic">Anodorhynchus hyacinthinus</Emphasis>): implications for conservation

The Hyacinth Macaw (Anodorhynchus hyacinthinus) is one of 14 endangered species in the family Psittacidae occurring in Brazil, with an estimated total population of 6,500 specimens. We used nuclear molecular markers (single locus minisatellites and microsatellites) and 472 bp of the mitochondrial DNA control region to characterize levels of genetic variability in this species and to assess the degree of gene flow among three nesting sites in Brazil (Pantanal do Abobral, Pantanal de Miranda and Piauí). The origin of five apprehended specimens was also investigated. The results suggest that, in comparison to other species of parrots, Hyacinth Macaws possess relatively lower genetic variation and that individuals from two different localities within the Pantanal (Abobral and Miranda) belong to a unique interbreeding population and are genetically distinct at nuclear level from birds from the state of Piauí. The analyses of the five apprehended birds suggest that the Pantanal is not the source of birds for illegal trade, but their precise origin could not be assigned. The low genetic variability detected in the Hyacinth Macaw does not seem to pose a threat to the survival of this species. Nevertheless, habitat destruction and nest poaching are the most important factors negatively affecting their populations in the wild. The observed genetic structure emphasizes the need of protection of Hyacinth Macaws from different regions in order to maintain the genetic diversity of this species.     

Four new Brazilian species of Lonchocarpus (Leguminosae, Papilionoideae, Millettieae)

Lonchocarpus castaneifolius, L. grazielae, L. longiunguiculatus, and L. montanus from Brazil are described and illustrated based on field and herbarium studies. The first species belongs to Lonchocarpus sect. Punctati and is restricted to northeastern Brazil (Bahia state). The other three are included in sect. Laxiflori. Lonchocarpus grazielae is restricted to the southern coastal region (Santa Catarina state), L. montanus is found in northeastern Brazil (Bahia and Piauí states), the west-central region (Goiás and Tocantins states) and the southeast (Minas Gerais state), and L. longiunguiculatus occurs in northeastern (Bahia state) and southeastern (Minas Gerais state) Brazil.     

Immature Stages of Hydrobiomorpha spinosa (Orchymont, 1928) (Coleoptera: Hydrophilidae)

The preimaginal stages of the Neotropical species Hydrobiomorpha spinosa (Orchymont) are described and figured for the first time. They are compared to the larvae of the New World species Hydrobiomorpha casta (Say) and to unidentified African and Australian larvae. Bionomical notes on this species are included.     

Sur l’existence de deux espèces d’Eremotherium E. rusconii (Schaub, 1935) et E. laurillardi (Lund, 1842) dans le Pléistocène supérieur du Brésil intertropical

Two recent discoveries in two “lagoas” of southeastern Piauí (North East of Brazil) allow us to describe and compare two very small-sized hemimandibles of two Megatheriidae. We attribute the first one, from the Lagoa dos Porcos, to a very young specimen of Eremotherium rusconii (Schaub, 1935), the gigantic Eremotherium well known in South America. We determine the other one, from the Lagoa do Quari, as an adult specimen of the small Eremotherium laurillardi (Lund, 1842). We confirm hereby our idea, written in 2000, of the reality of the latter species, which was not defined, like many authors think, on a juvenile tooth of the large species. The mandible of E. laurillardi is described for the first time. The mandible of the very young specimen of E. rusconii is also a rare piece.     

Notes on Neotropical Zoraptera, with descriptions of two new species

Three new species,four new records and an updated checklist of Habenaria (Orchidaceae) from Rio Grande do Sul,Brazil

Three new species of Habenaria (Orchidaceae) section Nudae from Rio Grande do Sul, southern Brazil, are described and illustrated: Habenaria australis, H. kleinii and H. sobraliana. These are the first records of H. sect. Nudae for the state. Based on the examination of living and dried specimens, a total of 33 species and 400 collections of Habenaria were recorded for Rio Grande do Sul. Based on this survey, an updated checklist of the genus Habenaria for Rio Grande do Sul has been compiled. Four species are known only from this state, while seven other species are restricted to southern Brazil, Argentina and Uruguay. Habenaria hieronymi, previously known only from Argentina, is recorded for the first time from Brazil, and H. brachyphyton, H. ekmaniana and H. melanopoda are new records for Rio Grande do Sul.

The male imago of Perissophlebiodes Savage is described, in addition to a new species of Askola Peters from Amazonas. Askola emmerichi Domínguez, Molineri and Mariano, so far recorded from Venezuela, is reported from Brazil and compared to the new species herein described. Askola yanoman, sp. nov. can be separated from other species of the genus by the following combination of characters: (1) general colouration yellowish brown with areas washed with greyish brown; (2) dorsal portion of eyes brown, eyes meet on meson of head; (3) penis yellowish brown with darker margin, extending beyond the posterior margin of the styliger plate.     

Phylogeny and taxonomic revision of Heteropachylinae (Opiliones: Laniatores: Gonyleptidae)

Heteropachylinae Kury, 1994 is currently considered an early lineage of Gonyleptidae Sundevall, 1833 and includes small harvestmen that occur in the Atlantic Forests, mainly in the Northeast Region of Brazil. The species of Heteropachylinae were spread in different subfamilies until the establishment of the group. As a result of that, until now there were no comparative works on the subfamily in the literature. In this study, the first systematic review for Heteropachylinae was carried out and the first phylogenetic hypothesis for their taxa is proposed, by means of a cladistic approach. A total of 102 morphological characters was coded for 21 terminal taxa: 11 species of Heteropachylinae, two species from the genus Mangaratiba Mello‐Leitão, 1940 (considered as Heteropachylinae before this paper), seven other gonyleptids, and one cosmetid. The data were analysed using heuristic search algorithms, resulting in one most parsimonious tree (280 steps, consistency index = 0.47, retention index = 0.63). A parsimony analysis under implied weights was also performed, resulting in three trees. According to the results, Heteropachylinae is a monophyletic and well‐supported group if Mangaratiba is excluded. This genus should be returned to where it was originally described – Pachylinae. The subfamily distribution is restricted from Ceará to Espírito Santo Brazilian states. Pseudopucrolia Roewer, 1912 is considered a senior synonym of Melloa Roewer, 1930, Thaumatoleptes Roewer, 1930, and Tribunosoma Roewer, 1943. Two species of Heteropachylus Roewer, 1913, Heteropachylus ramphonotus sp. nov. and Heteropachylus gracilis sp. nov. , from Bahia and Espírito Santo Brazilian states, are newly described. Heteropachylus is considered a senior synonym of Chavesincola Soares & Soares, 1946 and Aesotrinoma H. Soares, 1977. A new genus is also described for a new species from Bahia and Espírito Santo Brazilian states, Magnispina neptunus gen. et sp. nov. Lectotypes are designated for the following species: Pseudopucrolia incerta (Mello‐Leitão, 1928) comb. nov. , Pseudopucrolia discrepans (Roewer, 1943) comb.nov. , Pseudopucrolia rugosa (Roewer, 1930) comb. nov. , Heteropachylus inexpectabilis (Soares & Soares, 1946) comb. nov. and Heteropachylus spiniger Roewer, 1913. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 437–483.     

A new species of Pulvinaria (Homoptera: Coccidae) and a new locality record of Pulvinaria neocellulosa

A new soft scale insect of the tribe Pulvinariini, Pulvinaria hakonensis sp. nov., is described from Japan based on several adult females. The lectotype of Pulvinaria neocellulosa Takahashi, 1940 is designated and the species is redescribed and recorded from Japan for the first time.     

Additions to the mycobiota of the weed Lantana camara (Verbenaceae) in southeastern Brazil

A sequel to the work of systematic surveying the mycobiota of Lantana camara aimed at finding potential biocontrol agents, was carried out during 1995–1996 covering part of its centre of origin in Brazil (state of Minas Gerais). Fifty-eight sampling sites, representing the four main climatic types in the state of Minas Gerais, were surveyed. Additional ad hoc collections were made in the states of Bahia, Espírito Santo, Paraná Rio de Janeiro and São Paulo. Fifteen fungal species were recorded in association with L. camara including the previously undescribed species Phomopsis lantanae-glutinosae sp. nov. Five fungi are also newly recorded on this host in Brazil: Cercospora lantanicola Corynespora cassiicola Meliola ambigua Mycovellosiella lantaniphila and Phomopsis lantanae. The following fungi, previously recorded on L. camara in Brazil, are recorded here for the first time in Minas Gerais: Dendryphielia aspera Micropustulomyces mucilaginosus Mycovellosiella lantanae Pseudocercospora guianensis and Puccinia lantanae.     

Richness and diversity of sand flies (Diptera,Psychodidae) in an Atlantic rainforest reserve in southeastern Brazil

Our objective was to study and evaluate the richness and diversity of Phlebotominae fauna in the Duas Bocas Biological Reserve (DBBR) in the state of Espírito Santo, in southeastern Brazil. Sand fly collections were carried out during four consecutive nights each month between August 2007 and July 2008 at DBBR by using CDC automatic light traps and an illuminated Shannon trap. Specific richness (S) and Shannon diversity index (H) was calculated for each trap. We collected 18,868 sand flies belonging to 29 species and 13 genera. Nyssomyia yuilli yuilli was the most abundant species followed by Psychodopygus ayrozai, Ps. hirsutus, Psathyromyia pascalei, and Ps. matosi. We recorded Brumptomyia cardosoi, Br. troglodytes, and Ps. geniculatus for the first time in the state of Espírito Santo. We discuss the differences in diversity and richness of the sand flies in both traps and in relation to other Brazilian localities and biomes. We also discuss the possibility of wild transmission of Leishmania in the DBBR and the influence of the sand fly species in leishmaniasis transmission to the adjacent areas of the reserve.     

Mayflies (Ephemeroptera) from Reserva Ecológica Michelin,Bahia, Brazil

New records and distributional notes are provided for Reserva Ecológica Michelin, an Atlantic Forest fragment near the southern coast of Bahia State, Brazil. Two families, four genera and five species are recorded for the first time in Bahia State. Additionally, one family, two genera and three species are also recorded for the first time in the Northeast Region of Brazil, resulting in nine families, 48 genera and 96 species recorded to this region. Amongst the recorded species, Hermanella mazama (Nascimento, Mariano, and Salles, 2012) has been classified as an endangered species on the official Brazilian red list.     

The invasive gall wasp Quadrastichus erythrinae (Hymenoptera: Eulophidae) in South America: is classical biological control needed?

The invasive gall wasp Quadrastichus erythrinae, a pest of Erythrina plants, is recorded for the first time in South America in Espírito Santo, Brazil. Research on Q. erythrinae and its potential natural enemies in this region is required to determine the need for classical biological control of this invasive pest.     

Hydraena (Hydraenopsis) ateneo,new species (Coleoptera,Hydraenidae) and other aquatic Polyphaga from a small habitat patch in a highly urbanized landscape of Metro Manila,Philippines

Seven species of Hydraenidae, Hydrophilidae and Elmidae are recorded from temporary freshwater habitats at the Ateneo de Manila University Campus in the metropolitan area of Manila, Philippines. They were identified as Enochrus (Lumetus) fragiloides d’Orchymont, Helochares (Hydrobaticus) lepidus d’Orchymont, Helochares (Helochares) pallens (MacLeay), Hydraena (Hydraenopsis) scabra d’Orchymont, Hydraena (Hydraenopsis) palawanensis Freitag & Jäch (new record for Luzon Island), Stenelmis sp. A further hydraenid species was unknown to science and is newly described: Hydraena (Hydraenopsis) ateneo Freitag, sp. n. Aedeagus, gonocoxite, spermatheca, and female tergite X are illustrated by computer-based line drawings. Habitus images of all three Hydraena Kugelann species recorded and a checklist of the Philippine Hydraena are provided. The presence of these seven species in the Ateneo campus is briefly discussed in regard to the area’s history. Measures to maintain and extend semi-natural islands of biodiversity in urban areas are suggested.
