Benthic harpacticoids were collected for the first time at Lake Tahoe, California-Nevada, United States. Two species were identified as members of the genus Attheyella Brady, 1880. The genus Attheyella comprises about 150 species within six subgenera, but only twelve species have previously been reported from North American freshwater habitats. The two new species of Attheyella described here have a 3-segmented endopod on P1 and 2-segmented P2–P4 endopods, the distal segment of exopod of P2–P4 has three outer spines, and the P5 has five setae on the exopod and six setae on the baseoendopod. Attheyella (Attheyella) tahoensis
sp. n. most closely resembles Attheyella (Attheyella) idahoensis (Marsh, 1903) from Idaho, Montana, and Alaska (United States) and Attheyella (Attheyella) namkungi Kim, Soh & Lee, 2005 from Gosu Cave in South Korea. They differ mainly by the number of setae on the distal endopodal segment of P2–P4. In addition, intraspecific variation has been observed on the caudal rami. Attheyella (Neomrazekiella) tessiae
sp. n. is characterized by the extension of P5 baseoendopod, 2-segmented endopod of female P2–P3, and naked third seta of male P5 exopod. The two new species are likely endemic to Lake Tahoe, an isolated alpine lake within the Great Basin watershed in the western United States. 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

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 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

A new species of paracalanid calanoid copepod Parvocalanus
leei
sp. n., is described from specimens collected in shallow waters of Western Korea. The new species is closely similar to Parvocalanus
arabiensis (Kesarkar & Anil, 2010), Parvocalanus
crassirostris (F. Dahl, 1894), Parvocalanus
latus Andronov, 1972, and Parvocalanus
scotti (Früchtl, 1923) in having two short terminal spines on the distal segment of the fifth leg and a similar rostrum in the female, but can be readily distinguished from its congeners by the body size, relative length of antennules, segmentation of endopod of leg 1, and pattern of ornamentation of spinules on legs 1 to 4 in the female. The taxonomic position of Parvocalanus
arabiensis and the validity of the genus Parvocalanus Andronov, 1970 are also discussed. 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

Pseudofornicia
gen. n. (Hymenoptera: Braconidae: Microgastrinae) is described (type species: Pseudofornicia
nigrisoma
sp. n. from Vietnam) including three Oriental (type species, Pseudofornicia
flavoabdominis (He & Chen, 1994), comb. n. and Pseudofornicia
vanachterbergi Long, (nom. n. for Fornicia
achterbergi Long, 2007; not Fornicia
achterbergi Yang & Chen, 2006) and one Australian species (Pseudofornicia
commoni (Austin & Dangerfield, 1992), comb. n.). Keys to genera with similar metasomal carapace and to species of the new genus are provided. The new genus shares the curved inner middle tibial spur, the comparatively small head, the median carina of the first metasomal tergite and the metasomal carapace with Fornicia Brullé, 1846, but has the first tergite movably joined to the second tergite and the third tergite 1.1–1.6 × as long as the second tergite medially and is flattened in lateral view. One of the included species is a primary homonym and is renamed in this paper. 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

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
