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

The genus Trachionus Haliday, 1833 (Hymenoptera, Braconidae, Alysiinae, Dacnusini) is reported for the first time from China. The genus is represented by four new species from Shaanxi province (NW China), which are described and illustrated. An identification key to the species in China is presented, a key to the genera of the Trachionus group and notes on the relationships with other Palaearctic species are added. 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

bellus
sp. n. and Paramesosciophilodes
rarissima
sp. n., from the Jiulongshan Formation at Daohugou Village, Inner Mongolia, China, are described in the extinct family Mesosciophilidae. Altogether seven genera with 21 species of mesosciophilids have been described from the Jurassic of Siberia and Kazakhstan, the Lower Cretaceous of Transbaikalia, and the Middle Jurassic of Inner Mongolia. An emended generic diagnosis of Paramesosciophilodes and a list of known taxa of mesosciophilids are provided. 相似文献

Phragmotic or “door head” ants have evolved independently in several ant genera across the world, but in Africa only one case has been documented until now. Carebara
elmenteitae (Patrizi) is known from only a single phragmotic major worker collected from sifted leaf-litter near Lake Elmenteita in Kenya, but here the worker castes of two species collected from Kakamega Forest, a small rainforest in Western Kenya, are studied. Phragmotic major workers were previously identified as Carebara
elmenteitae and non-phragmotic major and minor workers were assigned to Carebara
thoracica (Weber). Using evidence of both morphological and next-generation sequencing analysis, it is shown that phragmotic and non-phragmotic workers of the two different species are actually the same and that neither name – Carebara
elmenteitae or Carebara
thoracica – correctly applies to them. Instead, this and another closey related species from Ivory Coast are both morphologically different from Carebara
elmenteitae, and thus they are described as the new species Carebara
phragmotica
sp. n. and Carebara

Three new Hagnagora Druce species (Geometridae, Larentiinae) are described: Hagnagora
richardi Brehm, sp. n. from Ecuador, Hagnagora
hedwigae Brehm, sp. n. from Ecuador, and Hagnagora
mirandahenrichae Brehm, sp. n. from Costa Rica. A checklist of taxa assigned to Hagnagora is provided. Hagnagora is provisionally divided into six clades: the anicata clade (6 species), the buckleyi clade (3 species), the croceitincta clade (3 species), the ephestris clade (3 species), the mortipax clade (4 species) and Hagnagora
subrosea (1 species). Two taxa are revived from synonymy: Hagnagora
catagrammina Druce, stat. rev. and Hagnagora
luteoradiata Thierry-Mieg, stat. rev. Two taxa are reinstated from subspecies to species level: Hagnagora
acothysta Schaus, stat. rev. and Hagnagora
jamaicensis Schaus, stat. rev. Four taxa are provisionally removed from Hagnagora: “Hagnagora” ignipennis, “Hagnagora” mesenata, “Hagnagora” vittata, and “Hagnagora” ceraria. After these changes, the genus Hagnagora now comprises 20 valid species. 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

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

New material collected recently throughout the Afrotropical region has led to a major reassessment of taxa within the genera Anelaphinis Kolbe, 1892, Atrichelaphinis Kraatz, 1898 and other closely related genera. As a result, the name Megalleucosma Antoine, 1989 is here synonymised with Anelaphinis and a lectotype is designated for the type species, Cetonia
dominula Harold, 1879. The genus Atrichelaphinis is redefined and a new subgenus, Atrichelaphinis (Eugeaphinis), is proposed for Elaphinis
simillima Ancey, 1883, Elaphinis
vermiculata Fairmaire, 1894, Niphetophora
rhodesiana Péringuey, 1907, Atrichelaphinis
deplanata Moser, 1907 (with Anelaphinis
kwangensis Burgeon, 1931 as junior synonym) and Anelaphinis
sternalis Moser, 1914. Additionally, three new species and one new subspecies are recognised and described in this new subgenus: Atrichelaphinis (Eugeaphinis) bomboesbergica
sp. n. from South Africa; Atrichelaphinis (Eugeaphinis) bjornstadi
sp. n. from Tanzania; Atrichelaphinis (Eugeaphinis) garnieri
sp. n. from south–east Africa (Tanzania, Zimbabwe); and Atrichelaphinis (Eugeaphinis) deplanata
minettii
ssp. n. from central Africa (Malawi, Mozambique, Congo-Kinshasa, Congo-Brazzaville, South Africa, Rwanda, Zambia, Zimbabwe). The genus Atrichelaphinis is compared to its closest relatives and two separate keys are proposed, one for Atrichelaphinis and one for the sub-Saharan genera exhibiting completely or partially fused parameres. 相似文献

Two new species of the genus Zilchistrophia Weyrauch, 1960 are described from Eastern Ecuadorian rain forest: Zilchistrophia
hilaryae
sp. n. and Zilchistrophia
shiwiarorum
sp. n. These two new species extend the distribution of the genus considerably northwards, because congeners have been reported from Peru only. For the first time we present anatomical data (radula, buccal mass, morphology of the foot and the genital structure) of Zilchistrophia species. According to these, the genus belongs to the family Scolodontidae, subfamily Scolodontinae (=“Systrophiini”). The previously assumed systematic relationship of Zilchistrophia with the Asian Corillidae and Plectopylidae based on the similarly looking palatal plicae is not supported. 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

Ashea
megacephala, a new Peruvian genus and species is described. The specimens were collected on mushrooms and mushroom-associated trees. This genus can be readily distinguished from the other genera of the subtribe Gyrophaenina by the large head and the three indistinctly articulated labial palpomeres. A key to the known genera of Gyrophaenina is provided. A habitus photograph and illustrations of diagnostic characters are also presented. 相似文献

The discovery of three new species of Enyalioides from the tropical Andes in Ecuador and northern Peru is reported. Enyalioides
altotambo
sp. n. occurs in northwestern Ecuador and differs from other species of Enyalioides in having dorsal scales that are both smooth and homogeneous in size, a brown iris, and in lacking enlarged, circular and keeled scales on the flanks. Enyalioides
anisolepis
sp. n. occurs on the Amazonian slopes of the Andes in southern Ecuador and northern Peru and can be distinguished from other species of Enyalioides by its scattered, projecting large scales on the dorsum, flanks, and hind limbs, as well as a well-developed vertebral crest, with the vertebrals on the neck at least three times higher than those between the hind limbs. Enyalioides
sophiarothschildae
sp. n. is from the Amazonian slopes of the Cordillera Central in northeastern Peru; it differs from other species of Enyalioides in having caudal scales that are relatively homogeneous in size on each caudal segment, a white gular region with a black medial patch and several turquoise scales in males, as well as immaculate white labials and chin. A molecular phylogenetic tree of 18 species of hoplocercines is presented, including the three species described in this paper and Enyalioides
cofanorum, as well as an updated identification key for species of Hoplocercinae. 相似文献

A new species of anisogammarid amphipod, Jesogammarus (Jesogammarus) ikiensis
sp. n., is described from freshwaters in the Iki Island, Nagasaki Prefecture, Japan, based on results of morphological and molecular analyses. The new species is distinguished from all members of the genus by the combination of small number of setae on dorsal margins of pleonites 1–3, short and small number of setae on posterior margins of peduncular articles of antennae, mandibular article 1 without setae, well developed posterior lobes of accessory lobes of coxal gills on gnathopod 2 and pereopods 3–5, and pectinate setae on palmar margin of female gnathopod 2. A key to all the species of Jesogammarus is provided. 相似文献

A new species of freshwater crab, Potamonautes
isimangaliso
sp. n., is described from the western shores of False Bay, Hluhluwe, within the iSimangaliso Wetland Park, South Africa. While bearing a superficial resemblance to Potamonautes
lividus, the new species has been found to be genetically distinct, diverging from the former by 7.4–7.8% in mtDNA. Potamonautes
isimangaliso most closely resembles Potamonautes
lividus, but is distinguished by a unique suite of carapace characters, colouration, and size. The new species also lives in close association with oxygen-poor, fresh ephemeral pans, while the habitat of Potamonautes
lividus is well above the surface water line of the closest water body. An updated identification key for the Potamonautes species of South Africa is provided. 相似文献

Among the genera of the subfamily Scorpiopinae Kraepelin, 1905 Alloscorpiops remains rather discrete. Only recently new species were added to this genus, increasing its number from two to five. Therefore, species of Alloscorpiops remain rare. One remarkable new species, Alloscorpiops
troglodytes
sp. n., is described on the basis of a single male specimen collected inside a cave from Song Thanh Nature Reserve, Cha Vanh Commune, Nam Giang District in Vietnam. The new species presents most features exhibited by scorpions of the genus Alloscorpiops, but it is characterized by reduced size, slender body and elongated pedipalps. This new scorpion taxon represents the third species of Scorpiopinae discovered in a cave system, and may be another endemic element in the fauna of Vietnam. 相似文献

Here we present distributional records for Tanaidacea specimens collected during several Antarctic expeditions to the Ross Sea: the Italian PNRA expeditions (“V”, 1989/1990; “XI”, 1995/1996; “XIV”, 1998/1999; “XIX”, 2003/2004; “XXV”, 2009/2010) and the New Zealand historical (New Zealand Oceanographic Institute, NZOI, 1958-1961) and recent (“TAN0402 BIOROSS” voyage, 2004 and “TAN0802 IPY-CAML Oceans Survey 20/20” voyage, 2008) expeditions. Tanaidaceans were obtained from bottom samples collected at depths ranging from 16 to 3543 m by using a variety of sampling gears. On the whole, this contribution reports distributional data for a total of 2953 individuals belonging to 33 genera and 50 species. All vouchers are permanently stored in the Italian National Antarctic Museum collection (MNA), Section of Genoa (Italy) and at the National Institute of Water and Atmospheric Research (NIWA Invertebrate Collection), Wellington (New Zealand). 相似文献

A new species, Cherax
snowden
sp. n., from the Oinsok River Drainage, Sawiat District in the central part of the Kepala Burung (Vogelkop) Peninsula, West Papua, Indonesia, is described, figured and compared with the closest related species, Cherax
holthuisi Lukhaup & Pekny, 2006. This species is collected and exported for ornamental purposes and its commercial name in the pet trade is “orange tip” or “green orange tip”. Both species may be easily distinguished morphologically or by using sequence divergence, which is substantial, for considering Cherax
snowden
sp. n. to be a new species. 相似文献
