Notes on the Amazonian genus Hyogonia China (Hemiptera: Cicadellidae: Proconiini) with a description of a new species

Oncometopia batesi Distant, described from northern Brazil (State unknown), is transferred to the genus Hyogonia China. Hyogonia brasiliana sp. nov. is described from Northern Brazil, Pará State, the easternmost record of the genus. The new species is easily distinguished from all other Hyogonia species by the following combination of characters: (1) pronotum without distinct transverse contrasting band; (2) pygofer with short processes that do not attain its apex; (3) both pairs of aedeagal atrial processes divergent and short, never longer than aedeagal shaft; and (4) aedeagal caudal pair of atrial processes with bases close to each other, appearing as a single bifurcated robust process. Hyogonia batesi and H. brasiliana, together with an unidentified female from Acre State, represent the first authentic records of the genus Hyogonia from Brazil. Previous records of H. reticulata (Melichar) and H. youngi Emmrich and Lauterer from Brazil are erroneous as their recorded locality ‘Cumbase’ is most probably located in Peru (San Martín Department). Other new records from countries and major federal divisions are noted as follows: the genus Hyogonia (unidentified species) from Barinas State (Venezuela); H. batesi from Ecuador (Orellana Province); H. reticulata from Amazonas and Junín Departments (Peru); and H. youngi from Ecuador (Napo Province). A key to the known species of Hyogonia is provided.     

A new species of Ameroseius Berlese from Brazil,redescriptions of Ameroseius plumosus (Oudemans) and Ameroseius plumigera (Oudemans) (Acari: Mesostigmata: Ameroseiidae) based on the examination of type material

Ameroseius Berlese is the most numerous genus of family Ameroseiidae Evans (in Hughes 1961). Species of this genus have been reported from many regions around the world. A few species of this genus are known from Brazil. Ameroseius mineiro Narita, Bernardi and Moraes, sp. nov. is described based on the morphology of adult females and males collected from guano in caves of Minas Gerais State, Brazil. This is the second Ameroseius species described from Brazil. The holotypes of Ameroseius plumosus (Oudemans) and Ameroseius plumigera (Oudemans) were examined, given their close similarity with the species described in this paper, and they are here redescribed. A key is provided to separate these and other most similar species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:17A7D831-EC49-4D65-B06B-5E13EF52C696     

The species of the parasitic bee genus Osirinus (Hymenoptera,Apidae)

The species in the genus Osirinus Roig-Alsina are revised. Seven species are recognized, including O. ruficrus, new species, from south-eastern Brazil and O. tarsalis, new species, from western Brazil and Peru. Osiris parvicollis Ducke and O. santiagoi Almeida are transferred for the first time to Osirinus. An identification key based mainly on females is provided.     

Three new species of Gamasiphis (Acari: Mesostigmata: Ologamasidae) from Brazil,with complementary information about Gamasiphis plenosetosus Karg and a key to the world species of the genus

Gamasiphis Berlese is one of the most diverse genera of Ologamasidae, with 68 described species, corresponding to about 15% of the species of the family. Until now, a single species of this genus was known from Brazil. Gamasiphis salvadori sp. nov., Gamasiphis flechtmanni sp. nov. and Gamasiphis edmilsoni sp. nov. are described based on the morphology of adult females and males collected from litter and soil in Piracicaba, São Paulo State, Brazil. The holotype of Gamasiphis plenosetosus Karg, 1994 was examined, given its close similarity with the latter species, and complementary morphological information about it is provided. A key for the separation of females of the 60 recognizable world species of Gamasiphis is provided.     

Two new species of phytoseiid mites (Acari: Phytoseiidae) from the State of São Paulo,Brazil

Two new species of phytoseiid mites, Amblyseius ica and Typhloseiopsis dorsoreticulatus, from the State of São Paulo, Brazil, are described and illustrated. Amblyseius ica belongs to the americanus species group and dombeyus species subgroup, being the second species of that subgroup. Typhloseiopsis dorsoreticulatus is the first species of the genus Typhloseiopsis recorded outside Central America.     

A new earthworm genus Nouraguesia gen. nov. from French Guiana with description of two new species (Oligochaeta,Glossoscolecidae)

Nouraguesia gen. nov., consisting of three species, is described from Eastern Amazonia. Species belonging to this genus are middle-sized earthworms inhabiting, based on our experience, decomposing tree logs and space filled with detritus between leaf-axils and trunk (e.g. in some palm species). The new genus is morphologically similar to the genus Andiorrhinus, but differs from it by the presence of numerous caeca encircling the intestine in segment 27. The three species belonging to the newly established genus are known from state Amapa in Brazil (N. amaparis (Righi, 1971)); and French Guiana (N. parare sp. nov., N. souadae sp. nov.).     

The genus Hintonelmis (Coleoptera: Elmidae: Elminae), new species and records

ABSTRACT

Hintonelmis is a South American genus of Elmidae, comprising 11 species. Two further new species are here described and illustrated: Hintonelmis guianensis sp. nov. from Guyana, and Hintonelmis roellae sp. nov. from Brazil, can be distinguished from all other known members of the genus by their general colour pattern, some characters of pronotal and elytral sculpture, and the morphology of the male genitalia. The type material is deposited in the Natural History Museum, London, UK and Museum of Zoology of the University of São Paulo, São Paulo, Brazil. New distributional data for species of Hintonelmis are presented for the South of Brazil, Bolivia, Ecuador, and Guyana. We also provide an updated key for the genus species.

The first Leptanilloides species (Hymenoptera: Formicidae: Leptanilloidinae) from eastern South America

We describe a species of the exclusively Neotropical dorylomorph ant genus Leptanilloides (Leptanilloidinae), Leptanilloides atlantica sp. nov., based on workers collected in the Atlantic Forest, São Paulo, south-eastern Brazil. The 11 species of Leptanilloides described are known from relatively high altitudes in western America (from the Andes foothills in Bolivia to Sierra Morena in Mexico). The discovery of a Leptanilloides species in south-eastern Brazil represents a significant range extension for the genus; this new species shares characters with Leptanilloides biconstricta (Bolivia), Leptanilloides femoralis (Venezuela) and Leptanilloides gracilis (Mexico) and may be distinguished based on a combination of traits. The hypogaeic habits of Leptanilloidinae combined with inefficient collecting techniques may explain the paucity of information and of specimens of this group in most museum collections as well as its present apparent disjunct distribution. We compare Leptanilloides distribution to that of other organisms that show similar disjunct patterns in the Andes and montane sites in the Brazilian Atlantic Forest. http://www.zoobank.org/urn:lsid:zoobank.org:pub:E7E334AA-58C0-455D-A0A6-724D29226DD0     

New species and rediagnosis of Akamboja,and a new record for A. minimum (Coleoptera: Phengodidae,Mastinocerinae)

ABSTRACT

Akamboja was recently described based on five species with relatively small geographic ranges, all of which are within the boundaries of the South-eastern Atlantic Rainforest in Brazil. Recent expeditions in the continental island of Ilha Grande (Angra dos Reis, Rio de Janeiro State, Brazil) resulted in the discovery of a new species of the genus. Akamboja insularis sp. nov. has all diagnostic features of the genus, except for the branches of the antennomere IX, which are separated, unlike any other Akamboja. Here, we describe this new species, provide a new record for Akamboja minimum Roza et al. and propose a new diagnosis for the genus.

A new species of Pseudobranchiomma Jones (Polychaeta: Sabellidae) found amongst Brazilian coral,with a redescription of P. punctata (Treadwell, 1906) from Hawaii

A new species of Pseudobranchiomma Jones, 1962 is described from a collection of polychaetes associated with stony coral on the coast of São Paulo State, Brazil. Pseudobranchiomma minima sp. n. differs from the type species P. emersoni Jones and from most other Pseudobranchiomma species in lacking serrations along the outer surface of the crown radioles. Only one other recorded fairly small species, Pseudobranchiomma punctata (Treadwell, 1906, new combination), lacks such serrations and is redescribed here. The two species differ mainly in the configurations of the collars and chaetae. This genus has characters more in common with Bispira than with Branchiomma.     

Species of genus Schizotheca Hincks (Bryozoa,Cheilostomata) described in the Atlantic‐Mediterranean region,with notes on some species of Parasmittina Osburn

Material held in collections, originally ascribed to the genus Schizotheca and originating from the NE Atlantic and Mediterranean, is revised. Two new species are described: Schizotheca carmenae sp. nov. from Azores and Portugal, originally cited as Strophiella tubigera [sic], and Schizotheca buski sp. nov. from Cape Verde and Brazil, originally cited as Schizotheca fissa. Schizotheca talismani, also from Cape Verde, is redescribed from original material and transferred to the genus Parasmittina. The Atlantic species Schizotheca tuberigera is redescribed and a new synonymy is established. Schizotheca aviculifera, from Morocco, is also redescribed and a lectotype designated. A lectotype is also chosen for Schizotheca fissa, type species of the genus. Schizotheca lepida, from north France, is considered to be an unrecognizable species.     

A synopsis of Martarega White, 1879 (Insecta: Heteroptera: Notonectidae) occurring in the Brazilian Amazonia,with descriptions of three new species

The genus Martarega comprises 15 species and nine of these have been recorded in northern Brazil. Martarega pydanieli sp. nov. from Rondônia, while Martarega nieseri sp. nov. and M. barcelos sp. nov. from Amazonas are described here. Six known species are recorded in the Brazilian Amazonian Region (Amazonas, Pará, Rondônia and Roraima): M. brasiliensis, M. chinai, M. gonostyla, M. membranacea, M. oriximinaensis, and M. uruguayensis. At the outset of this survey the genus Martarega of the Brazilian Amazonian Region held 12 species, but no specimens of M. mcateei, M. hungerfordi, and M. williamsi were collected in the regions sampled. Martarega brasiliensis is newly recorded from Roraima, which comprises the first record of members of this genus in this State. Martarega uruguayensis is newly recorded from Pará and Rondônia, while M. gonostyla from Rondônia. Distinct keys to males and females of Martarega occurring in this region, including these new species, are provided.     

Revision of the genus Cylindrommata Tippmann (Insecta: Coleoptera: Cerambycidae)

The monotypic genus Cylindrommata is revised, and three new species are described from Brazil. Cylindrommata aurantia sp. nov. is recorded from the states of Rio de Janeiro and São Paulo, and differs from other species principally by having the prothorax tuberculate at the sides, pronotum subplane and elytra orangish. Cylindrommata lustrata sp. nov. is from Minas Gerais, and has the prothorax without tubercles, rounded at the sides, and elytra short and black with dark-blue reflections. Cylindrommata susanae sp. nov. is from Minas Gerais, Rio de Janeiro, and São Paulo, and has the prothorax without tubercles, parallel at the sides, and elytra yellowish. A key to the species is provided, and all the species are illustrated.     

New Australonura Cassagnau 1980 (Neanuridae: Neanurinae) from Brazil

Two new species of Australonura Cassagnau 1980 from Brazil, Australonura neotropica sp. nov. and Australonura gili sp. nov., are described and illustrated. The species occur in sympatry at a high altitude plateau of the ‘Serra de Itatiaia’, a mountainous range in the southeast region of the country. These two species are the first record of Australonura for Brazil. A modified diagnosis of the genus is provided.

Nesting biology and behavioural ecology of the solitary bee Monoeca haemorrhoidalis (Smith) and its cleptoparasite Protosiris gigas Melo (Hymenoptera: Apidae: Tapinotaspidini; Osirini)

The species Monoeca haemorrhoidalis, the largest species in the genus, occurs in the Atlantic rainforest of southeastern and southern Brazil. The aim of this study was to investigate the nesting ecology of M. haemorrhoidalis and its interactions with natural enemies. Nest aggregations were studied in an area at the transition between Dense and Mixed Temperate Rainforest, south Brazil. The period of nest construction and cell provisioning started in October and stopped in February. Plant species of the families Orchidaceae, Styracaceae and, mainly, Malpighiaceae, were the most important pollen and floral oil resources that were used in brood cell provisioning. During the nest construction activities, 27 insect species were observed at the nesting sites. The cleptoparasitic bee Protosiris gigas was one of the main causes of M. haemorrhoidalis mortality. Some behavioural and biological data of P. gigas are also reported.
