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.     

Snout mites from caves in Brazil,with description of a new species (Acari: Trombidiformes: Bdellidae)

In this paper we describe the first species of the genus Cyta from Brazil, Cyta troglodyta sp. nov., with a key to the world species of the genus. New records of mites of the family Bdellidae are reported from caves in Brazil.     

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.     

On the genus Orcus Mulsant with descriptions of new species (Coleoptera: Coccinellidae: Chilocorini)

Three new species of the genus Orcus from Papua New Guinea are described and illustrated: Orcus frommi, Orcus nietzschei and Orcus popperi. New records of Orcus cinctus Weise from New Britain Island of Papua New Guinea and Orcus lafertei Mulsant from New Guinea (Papua New Guinea) are given. An updated key to Orcus species is presented.     

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 genus and two new species of Pudeoniscidae Lemos de Castro 1973 (Crustacea: Isopoda: Oniscidea) from Brazil

To date, the family Pudeoniscidae includes six species and three genera, Pudeoniscus, Brasiloniscus and Iansaoniscus, with distributions restricted to Brazil. Here, we redefine the family Pudeoniscidae based on the discovery of a new genus and two new species, Oxossioniscus pataxo sp. nov. and Oxossioniscus akoko sp. nov., from the Brazilian Atlantic forest in the state of Bahia, and on the examination of Pudeoniscus birabeni and Pudeoniscus obscurus. Moreover, P. obscurus is re-described and new records are provided for P. birabeni.

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.

Water mites of the family Hygrobatidae Koch from southern Africa (Acari: Hydrachnidia)

New records are given of the water mite family Hygrobatidae (without the genus Atractides) from southern Africa (South Africa, Botswana, Namibia). In addition to one new subgenus of the genus Hygrobates, namely Inflatibates, four new species are described, namely Hygrobates draconicus, H. laceratoides, H. okavangoensis, and H. inflatipes as well as one new subspecies, namely Hygrobates spathuliferus cederberg. The following synonyms are established: the subgenus Capobates Thor with Hygrobates Koch, Hygrobates sanguineus transvaalensis K. O. Viets with Hygrobates spathuliferus (Lundblad), and Ambiguobates permixtus agnewi K. O. Viets with Ambiguobates permixtus K. Viets. The male of Australiobates pilosus (K. Viets) is described for the first time. The synonymization of Diversibates with Australiobates can now be confirmed. Finally, keys are given for the known genera of southern Africa, as well as for all known species of the genus Hygrobates from southern Africa.     

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.     

New species and records of earthworms from Jamaica with notes on the genus Eutrigaster Cognetti, 1904 (Octochaetidae: Oligochaeta)

Details are presented of earthworm collections from Jamaica. Eleven species are reported, eight being new records of which two are new species, to bring the total number of species known from the island to 16 and the number of families represented to six. The geographical affinities of each species and its faunal status are summarized. The new species are members of the genus Eutrigaster Cognetti (Octochaetidae) whose validity is reviewed; a table is provided for the identification of the 11 Central American and Caribbean species currently included in the genus.     

A new species of arboreal salamander (Caudata: Plethodontidae: Pseudoeurycea) from the mountains of Oaxaca,Mexico

Recent surveys of the plethodontid salamander fauna of Oaxaca, Mexico, disclosed the existence of a new, morphologically distinct arboreal species of the genus Pseudoeurycea. The new species, described here, is from the Sierra Mazateca in northern Oaxaca. Sequences of 1833 base pairs of the 16S, cytochrome b and ND4 mitochondrial DNA (mtDNA) genes from the new taxon were used to assess its phylogenetic position. Previous phylogenetic analyses based on mtDNA supported recognition of four clades within Pseudoeurycea: P. bellii, P. gadovii, P. juarezi and P. leprosa-Lineatriton species groups. One additional species, P. unguidentis, was not closely allied to any of the four groups. Re-analysis including the additional sequences reported here establishes a sister-group relationship between the new species and P. unguidentis. Moreover, it supports this clade as part of the P. juarezi species group.     

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.).     

A taxonomic revision of the genus Stempellinella (Diptera: Chironomidae)

The species of the chironomid genus Stempellinella are revised, described, and figured, and keys to known larvae, pupae, and male and female adults are presented. Five species new to science are diagnosed and described. An emended generic diagnosis of Stempellinella is given and morphological differences from its putative sister genus Zavrelia are discussed. The partial cytochrome oxidase subunit I (COI) gene sequences (DNA barcodes) of 10 Stempellinella species are presented and the variation in genetic distances within and between species is compared. The results indicate that DNA barcodes are suitable molecular markers for identification of Stempellinella species. The following life stages and species are diagnosed and described: the larva, pupa, male, and female of S. brevis, S. chambiensis, S. ciliaris, S. edwardsi, S. fimbriata sp. n., S. flavidula, S. leptocelloides, S. saltuum, and S. truncata; the pupa, male, and female of S. reissi and S. tamaseptima; the larva, pupa, and male of Stempellinella boltoni sp. n.; the pupa and male of S. lamellata sp. n.; the male and female of S. coronata; and the male of S. apicula, S. brevilamellae, S. distincta sp. n., and S. sublettorum sp. n. Two pupal types are described but not formally named. The following changes of combination are made: Stempellina chambiensis and Stempellina truncata are transferred to the genus Stempellinella. Zavrelia inopinata is listed as a new junior synonym of Stempellinella ciliaris.     

New species of the bee genus Augochlorodes Moure (Hymenoptera,Apidae s. l., Halictinae)

Five new species of the bee genus Augochlorodes from Brazil are described and the type species, A. turrifaciens Moure, 1958 Moure, J. S. 1958. Augochlorodes, a new genus of Halictinae from Brasil (Hymenoptera, Apoidea).. J Kansas Entomol Soc., 31(1): 53–55.  [Google Scholar], is redescribed. The new species are: A. clementis sp. nov. (from the states of Paraná, Santa Catarina and Rio Grande do Sul), A. incomitatus sp. nov. (Rio Grande do Sul), A. politus sp. nov. (Paraná), A. rostratus sp. nov. (Rio Grande do Sul) and A. vachali sp. nov. (Paraná, Santa Catarina, São Paulo). A discriminant function analysis using head measurements is presented to help distinguish the species. An identification key for the species is provided.     

Stenothoidae (Crustacea: Amphipoda) of hydrothermal vents and surroundings on the Mid‐Atlantic Ridge,Azores Triple Junction zone

Four new species of Stenothoidae were collected from the Azores Triple Junction zone during different French cruises on the Mid‐Atlantic Ridge. One of the species belongs to the genus Torometopa (T. saldanhae) and is the first record of this genus in the Atlantic Ocean. The three other species belong to the genus Stenothoe (S. divae, S. marvela, and S. menezgweni). It is not possible to determine from morphological and ecological characters whether these amphipod species are endemic to hydrothermal systems or are bathyal species that may be found away from vent sites.     

Species of Staurotheca Allman, 1888 (Cnidaria: Hydrozoa: Sertulariidae) from US Antarctic expeditions,with the description of three new species

Seventeen species of the genus Staurotheca Allman have been studied, three of which are new to science (Staurotheca abyssalis sp. nov., S. densa sp. nov. and S. profunda sp. nov.). The material studied was collected by several US Antarctic expeditions. Each species is described and figured, the systematic position amongst allied species discussed and available data concerning autecology and geographical distribution given. The remaining six known species of the genus are also considered, regarding synonymy, autecology and geographical distribution. The type material of two poorly known species of Staurotheca, S. juncea (Vanhöffen) and S. pachyclada (Jäderholm) has been re-examined, re-described and figured. Finally, a general survey of the bathymetrical and biogeographical distribution of the known species of Staurotheca is given.
