Three new species of Mesochra Boeck, 1865, were found during two surveys in south‐western Iceland of the feeding ecology of juvenile lumpsucker Cyclopterus lumpus Linnaeus, 1758, in floating seaweed and the seasonality of harpacticoids in a low intertidal pool. Only two species of the genus, M. lilljeborgi Boeck, 1864 and M. rapiens (Schmeil, 1894), have been found in previous studies in Iceland. The three new species, Mesochra ingolfssoni sp. nov., Mesochra snoppa sp. nov., and Mesochra freyri sp. nov. resemble M. stellfeldi Jakobi, 1954 in the normal (not dwarfed) outer seta of both male and female P5 EXP, but differ in that M. stellfeldi possesses unequal inner baseoendopodal setae on the female P5. The three new species resemble M. pygmaea (Claus, 1863) in the equal inner baseoendopodal setae of the female P5, but differ in the dwarfed outer seta of the male and female P5 EXP present in M. pygmaea, and can be easily separated by shape of the rostrum, female P6, number of pinnate elements on the second antennular segment, general shape of the antenna and shape of the lateral and distal inner spines, among other character states.  相似文献

The paper is a review of the genus Pellenes (s. lat.) in the fauna of Central Asia and the Caucasus. The genus Pellenes(s. lat.) is redefined and subdivided into four subgenera according to the structure of genitalia: Pellenes(s. str.), Pelpaucus subgen. nov., Pelmultus subgen. nov. and Pelmirus subgen. nov. Altogether 23 species have been treated, of which nine are described as new to science: Pellenes amazonka sp. nov. (female), P. badkhyzicus sp. nov. (male), P. borisi sp. nov. (female), P. karakumensis sp. nov. (male), P. bonus sp. nov. (male), P. pamiricus sp. nov. (male and female), P. pseudobrevis sp. nov. (male and female), P. sytchevskayae sp. nov. (male and female) and P. turkmenicus sp. nov. (male and female). Five species are newly synonymized: P. maderianus Kulczyński, 1905 with P. epularis (O. P.-Cambridge, 1872); P. kulabicus Andreeva, 1976 and P. simoni (O. P.-Cambridge, 1872) with P. geniculatus (Simon, 1868); and P. albomaculatus Peng and Xie, 1993 with P. denisi Schenkel, 1963; P. tauricus (Thorell, 1875) is removed from synonymy with P. simoni (O. P.-Cambridge, 1872) and is shown to be a junior synonym of P. nigrociliatus (Simon in L. Koch, 1875). A lectotype is designated for Pellenes brevis Simon, 1868. P. campylophorous (Thorell, 1875) is recognized to be nomen dubium. Pellenes calvus (Simon, 1868) is excluded from the Central Asian fauna of Pellenes. Evarcha lapponica (Sundevall, 1832), comb. nov. (ex Pellenes), is proposed. Some morphological terms, e.g. the median septum, the epigynal flaps, the central blindending pocket and the newly proposed ‘compound terminal apophysis’, are discussed in relation to their homology.  相似文献

Amaga amagensis, the type species of the genus Amaga, and Amaga bogotensis are re-described. Detailed analysis of the morphology of A. amagensis revealed important taxonomic features, such as testes located dorsally to the supraintestinal parenchymal muscular layer, and secretory accumulations opening through the lateral margins of the body. These characters, as well as other morphological features, are discussed, culminating in an emendation of the generic diagnosis of Amaga. Amaga bogotensis exhibits a characteristic set of morphological features, namely an eversible penis, a male atrium lined with large musculosecretory papillae, and independent muscular coats around both male and female atrium. Therefore, a new genus is proposed for this species.  相似文献

First records of Coelotinae are reported from Laos. Five new species of the genus Draconarius are described from the northern Luang Nam Tha Province: Draconarius bounnami sp. nov. (male), D. latidens sp. nov. (female), D. postremus sp. nov. (male, female), D. songi sp. nov. (male) and D. tabularis sp. nov. (female). In addition, two new Coelotinae species are described from Vietnam: D. hanoiensis sp. nov. (female) and D. huongsonensis sp. nov. (female). Of the 429 currently valid Coelotinae species, 154 of them have only females described (36%). The embolus characteristics of those with males described (275 species, 64%) are reviewed. Two characters have been found that might be informative for the estimation of phylogeny, and their congruence with the current Coelotinae classification system is discussed. One character is the point from which the embolus arises and another is the embolus shape.  相似文献

A new genus of Dytiscidae, Borneodessus gen. n., is described for Borneodessus zetteli zetteli sp. n. (Sabah, East Malaysia) and Borneodessus zetteli kalimantanensis ssp. n. (East Kalimantan, Indonesia). The new genus belongs to the tribe Bidessini because of the presence of two-segmented parameres of the aedeagus. A modified male clypeus is an apomorphy for Borneodessus zetteli. The species habitually resembles some species of Africodytes Biström, 1988 (Africa), Amarodytes Régimbart, 1900 (South America), and some Clypeodytes Régimbart, 1894 (Old World tropics). However, a sister group relation or closer affinities to any of the genera of Bidessini could not be established. Borneodessus is so far the first genus of Dytiscidae which is endemic to Borneo, but we suggest a certain probability of its occurrence in other Sundaic areas. The species is a rheobiont, being collected from forest streams. We briefly address biogeographical aspects and provide a checklist of Bornean Dytiscidae, indicating the currently known degree of endemism.  相似文献

This is the first record from China of the bopyrid isopod genus Asymmetrione, of which the new species Asymmetrione globifera, a parasite of the hermit crab Dardanus hessii (Miers) in Beibu Gulf and South China Sea, is described. The female A. globifera differs from Asymmetrione nossibensis Bourdon in the shape of its barbula and ornamentation of the first oostegite. A tabulation of the occurrence of all currently known species of Asymmetrione is included. New genus Parasymmetrione is described. The type species, Parasymmetrione tuberculineata, sp. nov., a parasite of Clibanarius corallinus (H. Milne-Edwards) Xisha, is similar in appearance to Asymmetrione spp. but differs, in the female, in not having the propodi of its pereopods produced into sockets and having uniramous uropoda; the male of P. tuberculineata sp. nov. differs from species of Asymmetrione in having the dactyli of only its first pair of pereopods markedly longer than those of the following pereopods.  相似文献

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.  相似文献

A new species of the freshwater cyclopid genus Paracyclops Claus, 1893 collected from the state of Aguascalientes, Mexico is described based on female and male specimens. It has affinities with other forms with profusely ornamented caudal rami, such as Paracyclops carectum Reid and Paracyclops pilosus Dussart, but it can be distinguished by a combination of characters including details of the ornamentation of the coxa of leg 1, third antennular segment with incomplete suture line, inner margin of the caudal rami with scattered hair-like elements, and relatively long caudal rami, among other characters. The male is distinguished mainly by having the caudal rami completely covered by pilosity, which differs from all other known Paracyclops, including Paracyclops carectum. The new species has affinities with neotropical Paracyclops. Illustrated records and a morphological analysis of two more species of Paracyclops from Mexico, Paracyclops poppei and Paracyclops chiltoni, are also included in this contribution.  相似文献

Two new species of physalopterid nematodes are described from a skink (Scincidae) and a gecko (Gekkonidae) from the West Australian desert. Kreisiella chrysocampa gen. et sp. nov. (Spirurida: Physaloperidae) from Egernia inornata is characterized by the possession of a row of straight parallel denticles along the medial pseudolabial margins, male caudal alae unsupported by papillae, a truncated female tail and an anteriorly-placed vulva. The original female specimen of Physaloptera heterocephala Kreis, 1940 is transferred to this genus. In Physalopteroides filicauda sp. nov. (Physalopteridae) from Nephrurus laevissimus the external apical tooth present in immature worms is represented in adults by a knob-like structure, larger on the left pseudolabium. Both sexes possess a long slender tail terminating in a small knob. The spicules are markedly dissimilar and the vulva is surrounded anteriorly and posteriorly by horizontal rows of tubercules.  相似文献

ABSTRACT

We found that Pinotus foveicollis synonym of D. agenor, does not belong to this group of species, neither is synonym of D. agenor. Here the species is revalidated to Dichotomius (Luederwaldtinia) foveicollis, the female is re-described, and the male is described for the first time. Based on male diagnostic characters the species is moved from D. agenor to D. inachus species-group.  相似文献

The genus Adelpherupa is revised and now includes nine species. The following were previously described: A. flavescens Hampson, A. albescens Hampson, A. typicota (Meyrick) and A. terreus (Zeller), and there are five new species: A. costipuntalis, A. elongalis, A. aethiopicalis, A. lialuiensis and A. pontica. A. pontica was bred from rice in Malawi. Externally most species are very similar. Male and female genitalia are illustrated and additional characters for species identification are found in the tympanal organs, more specifically the sclerotizations of the zona glabra tympani.  相似文献

ABSTRACT

Noyesaphytis Polaszek & Woolley gen. nov. (type species Noyesaphytis lasallei Polaszek & Woolley sp. n. ) is described from Berenty, Tuléar, Madagascar. The genus differs from its closest relatives primarily in the structure of the female antenna, which has a single, elongate flagellum preceded by four anelli, the largest of which could be interpreted as a single anelliform funicle. This type of antenna is unknown in other Aphytini, but approaches the condition found in many Signiphoridae. Noyesaphytis possesses a character state that was until now thought to be an autapomorphy of Azotidae (sole genus Ablerus), being the groove in front of the propodeal spiracle. A second putative autapomorphy shared by Azotidae and Signiphoridae, and also Noyesaphytis, is the presence of anterior projections on the metasomal sterna. However, in Azotidae and Signiphoridae these are narrow, whereas as they are broader in Noyesaphytis. The form of the wing is consistent with Aphytini, although lacking a linea calva. The presumed male of Noyesaphytis lasallei has an antennal structure completely unknown in Aphelinidae, with a 1-segmented clava preceded by an extremely elongate single funicle, and four anelli. Differences between the female and male are discussed, some of which could indicate that the male might eventually be shown to belong to a different species, although the species are undoubtedly congeneric, despite the striking difference in antennal structure which is common in Aphelinidae. The male genitalia also suggest Aphytini. Based on a phylogenetic analysis of 50 morphological characters, we provisionally place Noyesaphytis in Aphytini pending the results of a forthcoming phylogenomic analysis. The new genus is named for its collector, John Noyes (NHM, London), and the new species is named after the late John La Salle.

In the Indo-Pacific area, insular rivers are mainly colonized by gobiids of the Sicydiinae subfamily. These species spawn in freshwater, where the free embryos drift downstream to the sea before returning to rivers to reproduce; they are amphidromous. These gobies are the greatest contributors to the fish diversity and have the highest levels of endemism. Among the nine known genera of Sicydiinae, only two have been found in the West Indian Ocean, and only one (Sicyopterus) is known from Madagascar. Recently, two surveys discovered a new species in the genus Sicyopus. Sicyopus lord sp. nov. differs from other species by a combination of characters that includes a particular colour pattern, similar in both sexes; more scales than its congeners in lateral series (35–43), transverse back series (12–18) and a shorter caudal fin length in male fish. This paper describes the new species and discusses the presence of this genus in Madagascar.  相似文献

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.).  相似文献

Three hosts from Indo-west Pacific including Kiribati, Guam Island and Australia were examined, and found to be infested by three species of the subfamily Argeiinae. We describe Paraeragia kiribatiensis gen. nov., sp. nov. from Kiribati infesting Synalpheus gracilirostris. The new genus is most related to Eragia and it can be distinguished by female with triangular pleon, lateral plates extend posteriorly, paired uropods, widely opened brood pouch. Argeiopsis guamensis sp. nov. from Guam Island infesting Synalpheus cf. stimpsoni. The new species is most similar to Argeiopsis inhacae but differs in female with curved posterior margin of first oostegite, partly fused pleomeres, and male with head separated from first pereomere, pleon as wide as seventh pereomere. We also record Stegoalpheon kempi from Australia for the first time, infesting Alpheus cf. perplexus. Keys to the nine genera of Argeiinae, and to three species of Argeiopsis are provided. A table for all 13 species of Argeiinae with localities and host records is also provided. A table comparing the distribution of lateral plates and morphology of pleopods and uropods among argeiine genera is presented.
