A new species of Hisonotus is described from the rio São Francisco basin. The new species can be distinguished from congeners by having (1) a unique coloration pattern of caudal fin with one black spot extending from its origin to the ventral lobe and two dark spots at the end of the lobe’s rays; (2) odontodes forming longitudinally aligned rows on head and trunk; (3) a functional V-shaped spinelet; (4) a single rostral plate at the tip of the snout; (5) by lacking contrasting dark geometric spots on the anterodorsal region of the body; (6) a lower caudal-peduncle depth; and (7) lower counts of the lateral median plates and (8) higher premaxillary and dentary teeth. The new species is the second described species of the genus Hisonotus in the rio São Francisco basin. It was found inhabiting the marginal vegetation of the rio São Francisco and three of its tributary, rio das Velhas, rio Paraopeba and rio Formoso. 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.

Our review recognizes 15 species of the integripennis species group of Geocharidius from Nuclear Central America, include three species previously described (Geocharidius
gimlii Erwin, Geocharidius
integripennis (Bates) and Geocharidius
zullinii Vigna Taglianti) and 12 described here as new. They are: Geocharidius
andersoni
sp. n. (type locality: Chiapas, Chiapas Highlands, Cerro Huitepec) and Geocharidius
vignatagliantii
sp. n. (type locality: Chiapas, Motozintla, Sierra Madre de Chiapas, Benito Juárez) from Mexico; Geocharidius

comayaguanus
sp. n. (type locality: Comayagua Department, 18 km ENE of Comayagua), Geocharidius
disjunctus
sp. n. (type locality: Francisco Morazán, La Tigra National Park), and Geocharidius
lencanus
sp. n. (type locality: Lempira Department, Celaque National Park) from Honduras. For all members of the group, adult structural characters, including male and female genitalia, are described, and a taxonomic key for all members of the integripennis species group is presented based on these characters. Behavioral and biogeographical aspects of speciation in the group are discussed, based on the morphological analysis. In all cases of sympatry, pairs of closely related species show greater differences in sizes than pairs of more remotely related species. Integripennis group species occupy six different montane areas at elevations above 1300m, with no species shared among them. Major faunal barriers in the region limiting present species distributions include the Motagua Fault Zone and a gap between the Guatemalan Cordillera volcanic chain and the Honduran Interior Highlands no higher than 900m in elevation. Highest species diversity is in the Guatematan Cordillera (six species), second highest in the Honduran Interior Highlands area (four species). 相似文献

In this paper we describe Drusus
sharrensis
sp. n., from the Sharr Mountains in Kosovo. Males of the new species are morphologically most similar to Drusus
krusniki Malicky, 1981, Drusus
kerek Oláh, 2011 and Drusus
juliae Oláh, 2011 but differ mainly in exhibiting (1) a differently shaped spinose area on tergite VIII; (2) intermediate appendages anteriorly curved in lateral view with broad tips in dorsal view; (3) inferior appendages with a distinct dorsal protrusion in the proximal half. Females of the new species are morphologically most similar to Drusus
krusniki, Drusus
kerek, Drusus
juliae, and Drusus
plicatus Radovanovic, 1942 but mainly differ in (1) segment X that is longer than the supragenital plate with distinctly pointed tips; (2) supragenital plate quadrangular with a distinct round dorsal protrusion; (3) a vulvar scale with a small median lobe. Results of phylogenetic species delimitation support monophyly of Drusus
sharrensis sp. n. and recover it as sister to a clade comprising (Drusus
pelasgus Oláh, 2010 + Drusus
juliae + Drusus
arbanios Oláh, 2010 + Drusus
plicatus + (Drusus
dacothracus Oláh, 2010 + Drusus
illyricus Oláh, 2010)). The new species is a micro-endemic of the Sharr Mountains, a main biodiversity hotspot in the Balkan Peninsula. Main threats to the aquatic ecosystems of this part of the Balkan Peninsula are discussed. 相似文献

We use mitochondrial and nuclear sequence data to show that three weakly electric mormyrid fish specimens collected at three widely separated localities in Gabon, Africa over a 13-year period represent an unrecognized lineage within the subfamily Mormyrinae and determine its phylogenetic position with respect to other taxa. We describe these three specimens as a new genus containing two new species. Cryptomyrus, new genus, is readily distinguished from all other mormyrid genera by a combination of features of squamation, morphometrics, and dental attributes. Cryptomyrus
ogoouensis, new species, is differentiated from its single congener, Cryptomyrus
ona, new species, by the possession of an anal-fin origin located well in advance of the dorsal fin, a narrow caudal peduncle and caudal-fin lobes nearly as long as the peduncle. In Cryptomyrus
ona, the anal-fin origin is located only slightly in advance of the dorsal fin, the caudal peduncle is deep and the caudal-fin lobes considerably shorter than the peduncle. Continued discovery of new taxa within the “Lower Guinea Clade” of Mormyridae highlights the incompleteness of our knowledge of fish diversity in West-Central Africa. We present a revised key to the mormyrid genera of Lower Guinea. 相似文献

The oegopsid squids Abraliopsis and Pterygioteuthis are abundant and diverse genera with taxonomic and distributional problems. Identification and distribution of species in the Mexican Pacific has been somewhat controversial. Here are provided a large series of new records for Abraliopsis
affinis, Abraliopsis
falco, Pterygioteuthis
gemmata, Pterygioteuthis
giardi and Pterygioteuthis
hoylei from the Gulf of California and off the SW coast of Mexico. All five species were collected in the central or the southern Gulf of California, or in both. Abraliopsis
affinis was found in seven samples with a total of 48 specimens, from 21°59'' to 24°53''12"N. Abraliopsis
falco was much less represented in the samples (14 specimens) but it was found in 10 localities, four of which correspond to the central-southern Gulf of California (north to 27°44''53"N) and six to SW Mexico (south to 16°49''18"N). In the case of Pterygioteuthis
gemmata, only two records (three specimens) were obtained, both in the SW Gulf of California, while Pterygioteuthis
giardi (nine specimens) records were all from the central Gulf of California (27°44''53” to 25°39''59"N). In the case of Pterygioteuthis
hoylei (nine specimens), material was obtained in six localities, also in a restricted latitudinal range (24°23''48” to 25°56''56"N). 相似文献

Paracreptotrema
rosenthali
sp. n. was discovered in the intestine of Xiphophorus
malinche and Pseudoxiphophorus
jonesii, collected from the headwaters of Río Malila, tributary of Río Conzintla, in the Río Pánuco basin, Hidalgo, México, during 2008–2009. The new species differs from the five known species of Paracreptotrema Choudhury, Pérez-Ponce de León, Brooks & Daverdin, 2006 by having vitelline follicles that extend from a level anterior to the pharynx to mid-testes, the seminal vesicle which is more extensively folded, and a wider cirrus sac. The new species resembles Paracreptotrema
heterandriae in the length of its ceca, which surpasses the posterior margin of the ovary but do not reach the testes. A key to the species of Paracreptotrema is provided. 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

Seven new species of Hypselostomatidae are described from the Chinese province Guangxi: Angustopila
dominikae Páll-Gergely & Hunyadi, sp. n., Angustopila
fabella Páll-Gergely & Hunyadi, sp. n., Angustopila
subelevata Páll-Gergely & Hunyadi, sp. n., Angustopila
szekeresi Páll-Gergely & Hunyadi, sp. n., Hypselostoma
socialis Páll-Gergely & Hunyadi, sp. n., Hypselostoma
lacrima Páll-Gergely & Hunyadi, sp. n. and Krobylos
sinensis Páll-Gergely & Hunyadi, sp. n. The latter species is reported from three localities. All other new species are known only from the type locality. Specimens nearly identical to the type specimens of Angustopila
huoyani Jochum, Slapnik & Páll-Gergely, 2014 were found in a cave in northern Guangxi, 500 km from the type locality. Adult individuals of Angustopila
subelevata
sp. n. (shell height = 0.83–0.91 mm, mean = 0.87 mm) and Angustopila
dominikae
sp. n. (shell height of the holotype = 0.86 mm) represent the smallest known members of the Hypselostomatidae, and thus are amongst the smallest land snails ever reported. We note that Pyramidula
laosensis Saurin, 1953 might also belong to Krobylos. Paraboysidia
neglecta van Benthem Jutting, 1961, which was previously included in Angustopila, is classified in Hypselostoma. 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

Jedlička 1931. Two species, Pterostichus
schuelkei Sciaky & Wrase and Pterostichus
wenxianensis Allegro & Sciaky, are moved from the subgenus Circinatus to Morphohaptoderus. An infra-subgeneric taxonomy is proposed for the subgenus Circinatus with four species groups. The male endophallus characters for most species of Circinatus were well studied, with three types of endophallus defined. A phylogenetic analysis based on adult morphological characters confirmed the infra-subgeneric classification and clarified some of the relationships among species. Two main lineages within Circinatus were identified from the phylogenetic analyses. Three of the four species groups were monophyletic, whereas the fourth group was paraphyletic. 相似文献
