Synopsis of the genus Pseudoperma Dillon and Dillon, 1946 (Coleoptera: Cerambycidae), with description of a new species

A synopsis of Pseudoperma is provided. This genus mainly differs from Onocephala and Stethoperma by the antennal tubercles well separated; antennae relatively short, in the female subequal to the body length; and scape and third antennomere subequal in length. Pseudoperma includes two species, P. chalcogramma (Bates, 1887) and P. patruelis (Breuning, 1940), both from Brazil; herein we describe one new species, Pseudoperma lingafelteri sp. nov. from Brazil (Rio de Janeiro). This species differs from its congeners mainly in having the frons and occiput covered with greyish pubescence, and the sides of the elytra with several interrupted or coalescent vittae. We provide new distribution data for Pseudoperma patruelis (Breuning, 1940) from Brazil, Minas Gerais, São Paulo and Santa Catarina, as well as illustrations and a key to the species of Pseudoperma.

Three new species of Benthana Budde-Lund (Isopoda, ‘Philosciidae’) from Brazil

Three new species of Benthana Budde-Lund, 1908 are described from material collected near São Fancisco de Paula, a town in the north-east of the southernmost Brazilian State, Rio Grande do Sul (RS). The new species are: Benthana serrana sp. nov., Benthana trinodulata sp. nov. and Benthana araucariana sp. nov. (from Araucaria Forest). The presence of more than one nodulus lateralis on coxal plate VII, a characteristic not previously known in the genus, is reported. New occurrences of B. picta (Brand, 1833) and B. taeniata (Araujo and Buckup, 1994) are also recorded. A method is given for defining the shape of the exopod of pleopod 1 of the male based on morphometry.     

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.

On taxonomy and hosts of Leptostylum Macquart, 1851 (Diptera: Tachinidae: Blondeliini), with description of a new species and a new host record

Tachinid flies are well known as being parasitoids of arthropods, mostly insects. Because of this, there is great economic interest in the biological control of pests using tachinids. Host records for Tachinidae, however, are still scarce, especially in the Neotropical region. A new species of the Neotropical genus Leptostylum Macquart was reared from Automeris naranja Schaus (Lepidoptera: Saturniidae), a new host record, in Jundiaí, São Paulo, Brazil. Leptostylum oligothrix Gudin and Messas sp. nov. is herein described, including diagnosis and the first illustration of female terminalia for the genus. Additionally, illustrations and remarks on type material of Leptostylum deposited at Museu de Zoologia de São Paulo (MZSP) are made, a taxonomic catalogue of Leptostylum is provided, and a host record is detailed, including a host catalogue for the genus.

A new genus and species of Sarcoglanidinae (Siluriformes: Trichomycteridae) from southeastern Brazil,with a re-examination of subfamilial phylogeny

Microcambeva barbata, n. gen. et sp., is described from rio São João, Estado do Rio de Janeiro. It is proposed as the sister group of Malacoglanis and Sarcoglanis, on the basis of three characters: pectoral fin longer than the head, pectoral fin rays projecting well beyond the fin membrane, and a forked caudal fin. Monophyly of the Sarcoglanidinae is confirmed by the unique possession of a long lateral process on the premaxilla and a separate anterior ossification on the palatine. A sister group relationship between the Sarcoglanidinae and the Glanapteryginae is supported by four synapomorphies: a posteriorly directed dorsal process on the quadrate, a large dorsal anteriorly directed process on the hyomandibula, vomer reduced and generalized miniaturization. A more inclusive group composed of Sarcoglanidinae, Glanapteryginae, Tridentinae, Vandeliinae and Stegophilinae is considered monophyletic, since they all exhibit a reduced interopercular patch of odontodes, a reduced or absent metapterygoid, reduction in the number of pleural ribs, and lack an elongate process on the parasphenoid.     

A new species of Passalus (Passalus) from Atlantic Rainforest,with a key and checklist for the Brazilian Petrejus group (Coleoptera,Passalidae)

ABSTRACT

A new species of Passalus is described from the Brazilian Atlantic Forest. A synthesis of the current state of knowledge concerning the Brazilian species of the Petrejus group is presented with a new key to the described Passalus lockerum sp. nov., which is characterized by the frontal area finely and sparsely punctate, interstices shiny; anteriorly with distinct rounded, coarse and shallow punctures, contiguous or not. Also, the secondary median frontal tubercles are close, vestigial to small and subcontiguous at base. Unique characteristic specific to the aedeagus are also important. The species is restricted to a protected conservation area of the Atlantic Forest in the state of Rio de Janeiro.

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.

An unusual new species of Trechona (Araneae: Mygalomorphae: Dipluridae), from quartzitic caves of the Diamantina Plateau,Minas Gerais,Brazil, with a key to the known species

Trechona diamantina sp. nov. is described from quartzite caves in Diamantina, central Minas Gerais State, Brazil. This represents the largest cavernicolous mygalomorph population ever recorded. The new species is the first Trechona recorded from a xeric habitat, namely the Rocky Fields on the Diamantina Plateau. T. diamantina sp. nov. is closely related to T. uniformis, both species possessing elongated male and female copulatory organs and both constructing distinct funnel-webs and sheet-webs in quartzite formations. T. diamantina sp. nov. is distinct in possessing less elongated embolus and receptacula seminis. A key for all valid species of the genus is given.

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.     

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.     

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.

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     

Identification of Megaselia scalaris (Loew, 1866) (Diptera: Phoridae) in mummified human body from Itacambira (MG), Brazil,using scanning electron microscopy and cuticular hydrocarbons

Insect puparia were found adhered to the ribs and other tissues in the abdominal cavity of a natural male mummy found in Itacambira (State of Minas Gerais, Brazil) dating to the Colonial Period. They were collected for identification by scanning electron microscopy, and for comparison of several morphological features with those described in the literature. The puparia were found open and dorsoventrally flattened, making it difficult to visualize the dorsal projections. The tegument is covered by tapered spines and contains rows of small tubercles on the dorsal and lateral regions of the puparium. The posterior spiracle consists of four parallel openings arranged in pairs. These results are indicative that the specimens belong to the species Megaselia scalaris (Loew, 1866) (Diptera: Phoridae). Additionally, cuticular hydrocarbons of the puparia were analysed by gas chromatography coupled to mass spectrometry and compared with the profile of M. scalaris reared in the laboratory.
