Two new species of Pseudancistrus, a genus diagnosed by non-evertible cheek plates and hypertrophied odontodes along the snout margin, are described from two drainages of the Brazilian Shield: Pseudancistrus
kayabi from the rio Teles Pires (rio Tapajós basin) and Pseudancistrus
asurini from the rio Xingu. The new species are distinguished from congeners (Pseudancistrus
barbatus, Pseudancistrus
corantijniensis, Pseudancistrus
depressus, Pseudancistrus
nigrescens, Pseudancistrus
reus, and Pseudancistrus
zawadzkii) by the coloration pattern. Pseudancistrus
kayabi has dark bars on the dorsal and caudal fins which are similar to that of Pseudancistrus
reus from the Caroní River, Venezuela. Pseudancistrus
asurini is unique among Pseudancistrus in having whitish tips of the dorsal and caudal fins in juveniles to medium-sized adults. 相似文献

The transversely-dividing flabellids consist of five genera (Truncatoflabellum, Placotrochides, Blastotrochus, Placotrochus, and Falcatoflabellum) and 45 species. A dichotomous key is provided for these five genera as well as the species of the genus Truncatoflabellum and Placotrochides, the other three genera being monotypic. A tabular key is also provided for the 38 species of Truncatoflabellum. Two new combinations are suggested (Truncatoflabellum
gambierense and Truncatoflabellum
sphenodeum) and two new species are described (Truncatoflabellum
duncani and Truncatoflabellum
mozambiquensis). All but one species are illustrated and accompanied by their known distribution and a guide to the pertinent literature for the species. New records of 19 of the 45 species are listed. The transversely-dividing flabellids range from the Middle Eocene to the Recent at depths of 2–3010 m, and constitute 60% of the 65 known extant species of transversely-dividing Scleractinia. 相似文献

The article describes a new species of the feather mite family Pteronyssidae (Acarina: Psoroptidia) from the Gray Sibia Heterophasia
gracilis (McClelland) (Passeriformes, Leiothrichidae) in India (Meghalaya, Jaintia Hills, Shnongrim village). Males of Timalinyssus
wahlangi
sp. n. differ from those of all Timalinyssus species by having the horseshoe-shaped epiandrum with a short anterior extension. Females of the new species differ from those of all previously known species of the genus in having the hysteronotal shield with deep lateral incisions between e2 and f2 setae. A key to all species of the genus Timalinyssus is presented. 相似文献

Hallodapomimus
antennatus
sp. n. (Hemiptera: Heteroptera, Miridae, Phylinae, Hallodapini) is described from a macropterous female found in Eocene Baltic amber. The new species can be recognized readily from the other species of the genus, mainly due to its unusual second antennal segment. A key for the identification of all known fossil Hallodapini is presented. 相似文献

A new genus and species of sea pen or virgulariid pennatulacean from the Gulf of Guinea in the tropical eastern Atlantic is described, and a key to the genera of the Virgulariidae is included. The new genus and species described here adds to the previously described five other genera of the family. It is distinguished by unique sclerite and polyp leaf characters from the superficially-similar genus Virgularia, which lacks conspicuous sclerites in the polyp leaves and coenenchyme (other than minute oval bodies that are generally <0.01 mm in length). 相似文献

A new genus of soft coral from the Republic of Congo is described, Complexum
gen. n. Nine West African octocoral species previously described in the genus Alcyonium by Tixier-Durivault (1955) are referred to this new genus, and a new species is described and figured, Complexum
pusillum
sp. n. The new species is characterized by having encrusting growth form and abundant spiny clubs in the surface of the polyparium. It colonizes shallow calcareous rocky banks (5 to 20 m depth) existing in coastal water of the region of Pointe-Noire. Based on molecular phylogeny this new genus is well separated from Alcyonium species. 相似文献

The Afrotropical Cynipoidea are represented by 306 described species and 54 genera in four families: Cynipidae, Figitidae, Liopteridae and Ibaliidae, the latter represented by a single introduced species. Seven of these genera are only represented by undescribed species in the region. Seven new genus-level synonymies, one genus resurrected from synonymy, 54 new combinations, one combination reinstated, and one new replacement name are presented. We provide identification keys to the families, subfamilies and genera of cynipoid wasps occurring in the Afrotropical region (Africa south of the Sahara, including Madagascar and southern Arabian Peninsula). Online interactive Lucid Phoenix and Lucid matrix keys are available at: http://www.waspweb.org/Cynipoidea/Keys/index.htm. An overview of the biology and checklists of species for each genus are provided. This paper constitutes the first contributory chapter to the book on Afrotropical Hymenoptera. 相似文献

Three new genera of Mimallonidae are described. The monotypic genus Tostallo
gen. n. is erected to contain “Perophora” albescens Jones, 1912, which was previously placed in the preoccupied genus Perophora Harris, 1841 and was never formally moved to a valid genus. Perophora is a junior homonym of Cicinnus Blanchard, 1852, but the name albescens is not appropriately placed in Cicinnus due to external and genitalia characteristics entirely unique to the species albescens. The female of Tostallo
albescens
comb. n. is described and both sexes are figured for the first time. Auroriana
gen. n. is erected to contain Auroriana
florianensis (Herbin, 2012), comb. n. previously described as Cicinnus
florianensis, and two new species: Auroriana
colombiana
sp. n. from Colombia and Auroriana
gemma
sp. n. from southeastern and southern Brazil. The female of Auroriana
florianensis is described and figured for the first time. Finally, the monotypic genus Micrallo
gen. n. is erected to include a new species, Micrallo
minutus
sp. n. described from northeastern Brazil. 相似文献

Cerocephalinae (Chalcidoidea, Pteromalidae) is a small group of parasitoid wasps characterized by a number of derived diagnostic features. Their hosts are endophytic beetles. So far, 43 species of Cerocephalinae have been described, including one fossil species from the Miocene. In this study, we add two new genera and species from Baltic and Dominican amber to the fossil record. Tenuicornus
dominicus
gen. et sp. n. is the second genus described from Dominican amber, and Pteropilosa
lailarabanorum
gen. et sp. n., described from Baltic amber, represents the oldest record of the subfamily, pushing the minimum age of Cerocephalinae back to the Eocene. Diagnostic characters of both species are discussed in comparison with other Cerocephalinae. An updated key to extant and fossil Cerocephalinae is presented. 相似文献

The mirine plant bug genus Paramiridius, previously known only from a single Taiwanese species, is reported from Indochinese Laos for the first time and redefined. Two additional species, Paramiridius
indochinensis and Paramiridius
laomontanus, are described as new to science. The female genitalic structures of the genus are documented for the first time. Habitus illustrations, figures of male genitalia, and key are provided for all three known Paramiridius species. 相似文献

The new genus Spartidelphax is described to house three species removed from the polyphyletic genus Delphacodes. The members of Spartidelphax are coastal species native to eastern North America, and probably feed exclusively on cordgrass (Poaceae, Spartina Schreb.). The taxonomy and nomenclature of the included species (viz. Spartidelphax
detectus, Spartidelphax
luteivittus, and Spartidelphax
penedetectus) are reviewed. Spartidelphax
luteivittus is a nomen dubium, whose type material is inadequate to provide diagnostic features contrasting with Spartidelphax
detectus and Spartidelphax
penedetectus. Diagnoses and a key are provided for the remaining Spartidelphax. 相似文献

A new genus of chewing louse as
Bobdalgleishia, and its type species Bobdalgleishia
stephanophallus
sp. n. (Phthiraptera) belonging to the Brueelia-complex (Ischnocera: Philopteridae) are described. Adults of the new species are fully described, illustrated and compared morphologically with the type species of Motmotnirmus Mey & Barker, 2014, which is its closest relative. The type host of Bobdalgleishia
stephanophallus is a subspecies of the great jacamar Jacamerops
aureus
ridgwayi Todd, 1943, an endemic Amazonian bird distributed in northern Brazil, and the type locality is the State of Pará. Bobdalgleishia is a remarkable genus with unique morphological and chaetotaxic characters which readily separate it from other members of the Brueelia-complex, in particular by having the first two marginal temporal and ocular setae very long. 相似文献

The New World tropics represents the most diverse region for tachinid parasitoids (Diptera: Tachinidae), but it also contains the most narrowly defined, and possibly the most confusing, tachinid genera of any biogeographic region. This over-splitting of genera and taxonomic confusion has limited progress toward our understanding the family in this region and much work is needed to revise, redefine, and make sense of the profusion of finely split taxa. In a recent analysis of the Neotropical genus Erythromelana Townsend, two species previously assigned to this genus, Euptilodegeeria
obumbrata (Wulp) and Myiodoriops
marginalis Townsend were reinstated as monotypic genera. In the present study, we demonstrate that Euptilodegeeria
obumbrata (Wulp), previously assigned to three different genera, represents in fact a species of the large New World genus Eucelatoria Townsend, in which females possess a sharp piercer for oviposition. We also show that the species Eucelatoria
carinata (Townsend) belongs to the same species group as Eucelatoria
obumbrata, which we here define and characterize as the Eucelatoria
obumbrata species group. Additionally, we describe Eucelatoria
flava
sp. n. as a new species within the Eucelatoria
obumbrata species group. Finally, we redescribe the genus Myiodoriops Townsend and the single species Myiodoriops
marginalis Townsend. 相似文献

From December 2012 to November 2014, 267 fish belonging to the family Profundulidae (representing nine of the 11 species of the genus Profundulus) were collected in 26 localities of Middle-America, across southern Mexico, Guatemala, and Honduras, comprising the distribution range of the genus, and analyzed for helminth parasites. Additionally, a database with all ten available published accounts of the helminth parasite fauna of this genus (the only genus within the family) was assembled. Based on both sources of information, a checklist containing all the records was compiled as a tool to address future questions in the areas of evolutionary biology, biogeography, ecology and phylogeography of this host-parasite association. The helminth parasite fauna of this fish group consists of 20 nominal species, classified in 17 genera and 14 families. It includes six species of adult digeneans, five metacercariae, two monogeneans, one adult cestode, three adult nematodes and three larval nematodes. The profundulid fishes are parasitized by a specialized group of helminth species (e.g.
