Chelodesmid studies. XVIII. On some new or poorly-known taxa in the tribe Batodesmini (Polydesmida: Chelodesmidae)

Summary

Some new and poorly-known taxa of batodesmine diplopods are described from northern South America, with notes on their affinities. New genera include Igaraparana, based on I. batesi, sp. nov. from Amazonian Colombia; Curimagua, based on C. granulata, sp. nov. from Edo. Falcon, Venezuela; and Cheirogonus, based on C. pittieri, sp. nov. from Panama. The inadequately proposed species Leptodesmus interrupticolor Silvestri (southeastern Ecuador) is redescribed and figured from type material, and referred to Cordilleronomus as its third species. The enigmatic genus Tunochilus Chamberlin, 1950, is clarified and referred to the Batodesmini from its incorrect location in the Cryptodesmidae, with notes and drawings made from a paratype of the type species T. marginis; the presumptive congener T. marcuzzii is described as new from material taken at Caracas, Venezuela.     

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.     

A new species of Hyalella from Colombia,and the redescription of H. meinerti Stebbing, 1899 from Venezuela (Crustacea: Amphipoda)

The new species H. quindioensis is described from Colombia. This species is close to H. paramoensis Andres, 1988 also in Colombia. Hyalella meinerti Stebbing, 1899 is figured and redescribed. The type locality for this species is Venezuela. However, it has a wide distribution including Colombia, Peru, Ecuador and Brazil.

Description of a new species of Asymmetrione (Isopoda: Bopyridae: Pseudioninae) infesting the hermit crab Paguristes tomentosus (Anomura: Diogenidae) from Peru,with a key to species and a review of southeastern Pacific bopyrids

A new species of bopyrid isopod is described from a host hermit crab Paguristes tomentosus collected from Pisco, Peru and assigned to the pseudionine isopod genus Asymmetrione Codreanu, Codreanu and Pike, 1965. This is the second species in the genus with less than 20° asymmetry in females, but agrees with all other species in the genus in having the characteristic “socket” on the propodus of the female's pereopods, and in all characters of the males. A key is provided to the 10 species now in Asymmetrione. New records of an Anathelges sp. from Pagurus villosus collected in central Chile are given but additional material is required to determine whether these specimens represent the eastern Pacific A. thompsoni or the western Atlantic A. hyptius. A review of all the bopyrid species known from the western South American coast, with remarks on their taxonomy and biology, is provided.     

Review of the southern temperate fish family Aplodactylidae (Pisces: Perciformes)

The southern temperate perciform fish family Aplodactylidae is reviewed. The monotypic genus Crinodus is relegated to the synonymy of the genus Aplodactylus, which is recognized as containing five species: A. arctidens Richardson from New Zealand and Australia (Victoria, South Australia and Tasmania); A. lophodon (Günther) restricted to south-eastern Australia (New South Wales and Victoria); A. westralis Russell restricted to south Western Australia; A. etheridgii (Ogilby) from the south-west Pacific (north-eastern New Zealand, Kermadec Islands, Lord Howe Island and Norfolk Island); and A. punctatus Valenciennes from the west coast of South America (Peru and Chile). A key to the species is given.     

Synopsis of the genus Ecoporanga Napp and Martins (Insecta: Coleoptera: Cerambycidae)

Two new taxa are described: Ecoporanga cooperi sp. nov. from Peru (Amazonas) and Ecoporanga wallacei sp. nov. from Ecuador (Tungurahua). The former differs from other species of the genus by the antennae and black legs and green elytra with metallic reflections. Ecoporanga wallacei differs from the other species by well-marked posterolateral depressions and tubercles near posterior margin of the pronotum, and apex of elytra laterally with recurved spine. A key to species of the genus 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.     

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     

Immature stages of Chinavia musiva (Berg, 1878): a unique pattern in the morphology of Chinavia Orian, 1965 (Hemiptera,Pentatomidae)1

Specimens of Chinavia musiva were collected in Parque Estadual do Espinilho (Barra do Quaraí County, RS, Brazil). Insects were reared under controlled conditions (24±1°C; RH 70±10%; 12h L:12h D), and fed on green beans (Phaseolus vulgaris L.). Eggs of C. musiva differ from the pattern observed in other species of the genus due to chorion colour and surface, and aero‐micropylar processes, number and shape. Exclusive features of the species in the nymphal stage are head and thorax dull; variegated pattern of abdomen, and openings of the scent glands in conspicuous tubercles. Developmental time was, on average, 52 days; females laid more frequently egg masses with 14 or 42 eggs. Females collected from the field as nymphs exhibited higher reproductive performance than females reared on green beans as nymphs and adults, suggesting that wild hosts could be essential for the species life cycle.     

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.
