Two new species of the chalcidoid wasp genus Nikanoria are described. Nikanoria flavicoxa sp. n. from Israel belongs to the N. nigra species-group. It is similar to N. szelenyii Zer., but differs in the shorter genae, longer funicular segments of the female, and enlarged stigmal knob. N. declivis sp. n. from Mongolia and Israel belongs to the N. pavlovskii species-group and resembles N. stigma Zer., but differs in the longer funicular segments of the female, enlarged antennal club, and straight sides of the clypeus. A key to species of the genus Nikanoria is given.  相似文献

A new species of Daptonema is described based upon morphological characters and 18S rRNA sequence. Daptonema matrona sp. nov. was collected in Pina Basin (north‐eastern Brazil). It differs from all other species of the genus by the presence of reduced cephalic setae and straight spicules. These features require an adaptation of the generic diagnosis. Moreover, the females are characterized by intra‐uterine development of the offspring, considered herein as their major autapomorphic feature. Molecular systematic analyses supported Daptonema matrona sp. nov. as a distinct genetic and evolutionary lineage. The data also indicate hypotheses of taxonomic synonymies amongst some related taxa from Xyalidae as well as the paraphyly of Daptonema. © 2010 The Linnean Society of London, Zoological Journal of the Linnean Society, 2010, 158 , 1–15.  相似文献

Dicranocentrus liuae sp. n. is described from the northern subtropical region of China. The new species is most similar to D. wangi Ma & Chen, 2007, but differs from it in the relatively shorter Ant. V, the 1+1 central macrochaetae on Abd. III, the number of chaetae on tenaculum, and the absence of dental spines. The systematic position of Dicranocentrus is also discussed. Present evidence, particularly S-chaetotaxy, indicates that the genus is closer to Heteromurus than to the unscaled species of Orchesella and Orchesellides.  相似文献

Two new species of Philaenus from Iran are described. Philaenus elbursianus sp. n. belongs to the Ph. signatus species group from the nominotypical subgenus. Philaenus iranicus sp. n. differs considerably from all the known representatives of the genus and was separated in a new subgenus Gyrurus subgen. n. The occurrence of this highly peculiar species in Iran may indicate that the center of origin of the genus Philaenus lies in this territory and not in the Mediterranean region as it was considered before.  相似文献

Four new species of trematodes of the genus Diplostomum are described from metacercariae found in fishes from Lake Tana in Ethiopia: Diplostomum garrae sp. n. from the lens of Garra dembecha, D. longicollis sp. n. from the lens of Barbus humilis, D. montanum sp. n. from the lens of Barbus humilis, and D. tilapiae sp. n. from the vitreous body of Oreochromis niloticus. The metacercariae of the new species considerably differ in morphology and size from those of all known Holarctic species. It is the first African record of metacercariae of the genus Diplostomum in fish.  相似文献

Onchobothrium malakhovi n. sp. was found in the spiral valve of the softnose skate Bathyraja (Arctoraja) sexoculata off the Simushir Island (Kuril Islands, Russia). The new species has bothridia with three loculi and no additional suckers on bothridia, single-toothed hooks unconnected by their bases, no spines at the bases of the hooks, dense matrix around the hook bases shaped as an unpaired butterfly wing, and a short and wide ovary. Onchobothrium malakhovi n. sp. differs from O. antarcticum and O. magnum in having a smaller total length, cirrus sac and ovary, smaller testes and eggs. Additionally, the new species differs from O. antarcticum by the absence of a vaginal sphincter and shorter bothridia; differs from O. magnum in having fewer proglottids and smaller vitelline follicles. It differs from O. farmeri, O. convolutum, and O. pseudouncinatum, by the absence of a small spine at the base of the hooks and the absence of accessory suckers on bothridia; from O. pseudouncinatum, additionally, by unconnected hooks; from O. schizacanthium, by the number of testes and by the presence of a postvaginal group of testes. Onchobothrium malakhovi n. sp. was placed among other members of the Onchoproteocephalidea with a high support based on the sequence data for the D1-D3 region of the 28S rDNA and cox1 gene. The phylogenetic position of the genus Onchobothrium sensu lato remains ambiguous. We suggest that Onchobothrium sensu lato is a complex genus containing at least two morphologically different groups of species. Onchobothrium farmer, O. convolutum, O. schizacanthium, and O. pseudouncinatum, for which there are no molecular genetic data, are considerably different morphologically from O. malakhovi n. sp., O. antarcticum, and O. magnum. A new genus might have to be established for the latter three species after the accumulation of genetic data.  相似文献

Two new tetraphyllidean species, Duplicibothrium cairae n. sp. and D. paulum n. sp., are described from Pacific cownose rays Rhinoptera steindachneri collected from the Gulf of California. D. cairae n. sp. differs from the only other known species in this genus, D. minutum, in its possession of two posteriorly bifurcating longitudinal septa on each bothridium and having a greater number of loculi per bothridium, wider bothridia and a greater number of segments per worm. D. paulum n. sp. differs from the above two species in being shorter, having two continuous longitudinal septa on each bothridium, rather than posteriorly bifurcating or absent longitudinal septa, having a greater number of loculi per bothridium and having fewer segments per worm. The generic diagnosis of Duplicibothrium is amended to reflect the inclusion of the two new species. Species of Duplicibothriumappear to be restricted to host species of the genus Rhinoptera. Systematic information gained from the study of these two new species supports the monophyly of the tetraphyllidean family Serendipidae and suggests that Duplicibothrium shares a phylogenetic heritage with species in the genera Glyphobothrium and Serendip, taxa that are also parasitic in cownose rays. Evidence for a phylogenetic relationship between serendipid species and species of Dioecotaenia is discussed, as are potential molluscan hosts for cestode species in Duplicibothrium and Dioecotaenia.  相似文献

Two new species of the genus Dolichopus Latreille (Diptera, Dolichopodidae) are described from Mongolia and Siberia. Dolichopus tschernovi Negrobov, Barkalov et Selivanova, sp. n. is similar to Dolichopus bayaticus Negrobov, 1976, but differs in the presence of one seta on the hind metatarsus, the shorter 3rd antennal segment, and in the structure of the hypopygium. Dolichopus lenensis Negrobov, Barkalov et Selivanova, sp. n. resembles Dolichopus setitarsis Negrobov et Barkalov, 1977, but differs in the slightly widened 2nd–4th segments of the middle tarsus, in the presence of one seta on the hind metatarsus, and in the structure of the hypopygium. Drawings of the antennae, tarsi, and hypopygium of the new species are given. The holotypes of the new species are deposited in the Zoological Institute, the Russian Academy of Sciences (St. Petersburg).  相似文献

Two new species of the oribatid mite family Suctobelbidae (Acari, Oribatida) are described from southern Chile. Niosuctobelba sphagnicola Ermilov, sp. n. differs from N. ruga Chinone, 2003 in the rostrum with a median incision and one pair of lateral teeth, the heads of bothridial setae rounded distally, the tectopedial fields not fused anteriorly, the notogastral setae barbed, and the body without striate ornamentation. Zeasuctobelba tierradelfuegoensis Ermilov, sp. n. differs from Z. trinodosa Hammer 1966 in a shorter body, the heads of the bothridial setae with thin apices, the tectopedial fields not fused anteriorly, and the notogastral humeral tubercles with longer cristae. An identification key to the known species of Zeasuctobelba is given. The genus Niosuctobelba is recorded for the Neotropical Region for the first time, while Zeasuctobelba is new to the fauna of Chile.  相似文献

An annotated species list of carpenter moths (Lepidoptera, Cossidae) of the Altai Mountain Range is presented. It includes 26 species from 3 subfamilies. Two species are new to science: Semagystia tarbagataica Yakovlev, sp. n. and Dyspessa saissanica Yakovlev, sp. n. The former differs from the other species of the genus (except Semagystia enigma Yakovlev, 2007 from southeastern Turkey whose wing pattern is totally reduced) in the absence of wing pattern; a specific clavate shape of the process on the costal margin of valve is also its important diagnostic character. Dyspessa saissanica Yakovlev, sp. n. belongs to the well-revised Dyspessa salicicola (Eversmann, 1848) species group (Yakovlev, 2005); the closest species is D. salicicola, which also has elongate processes of the pectinate antennae and a weakly developed ridge on the costal marginof valve. The newly described species is different in having a poorly developed dark pattern on the forewings, very broad bases of the processes of the transtilla, a thinner base of the aedeagus, and thinner lateral processes of the juxta. In conclusion, the carpenter moth fauna of the Altai Mountains is briefly analyzed.  相似文献

The new species Crocodorylaimus minor sp. n. is described, and Aporcella maitai (Yeates, 1967) comb. n. is redescribed. C. minor sp. n. resembles C. dadayi (Thorne et Schwanger, 1936), but differs from it in a shorter body, shorter odontostyle, absence of vulvar papillae, slenderer tail in females, and shorter spicules. Aporcelaimellus maitai Yeates, 1967 is transfered to the genus Aporcella Andrássy, 2002, taking the name Aporcella maitai (Yeates, 1967) comb. n. Aporcelaimellus heynsi Baqri et Jairajpuri, 1968 and Aporcelaimellus glandus Botha et Heyns 1991 are synonymized under Aporcella maitai (Yeates, 1967) comb. n. Identification keys to the valid species of the genera Crocodorylaimus and Aporcella are provided.  相似文献

Two new species of oribatid mites of the genus Lasiobelba (Oribatida, Oppiidae), Lasiobelba (Lasiobelba) daamsae sp. n. and Lasiobelba (Antennoppia) nepalica sp. n., are described from eastern Nepal. Lasiobelba (L.) daamsae sp. n. is most similar to L. (L.) remota Aoki, 1959 and L. (L.) gibbosa (Mahunka, 1985), however, it differs from both by the anterior part of pedotecta I specifically curved, rostrum pointed and exobothridial setae not shorter than bothridial setae. Lasiobelba (Antennoppia) nepalica sp. n. is most similar to L. (A.) granulata (Mahunka, 1986), however, it differs from the latter by the larger body size, exobothridial setae longer than rostral setae and bothridial setae not longer than interlamellar setae. An identification key to known species of Lasiobelba is given.  相似文献

A new species, Viracochiella orientalis sp. n., from the southern part of Sakhalin is described. The species differs in the shape of cuspises with strong medial teeth and in the absence of translamellae. The smooth notogaster, shorter interlamellar and genital setae, and some other characters distinguish this species from V. tuberculata. This species differs from V. sergienkoae in the number of genital setae (V. sergienkoae has five pairs), shorter interlamellar setae, smooth trichobothria, fine pore areas without borders of sclerotization, and thin hysterosomal setae.  相似文献

Four new species of the bristletail families Ateluridae (Atelura abkhazica sp. n. and Nipponatelurina caucasica sp. n.) and Lepismatidae (Lepisma xylophila sp. n. and L. adygei sp. n.) are described. Atelura abkhazica sp. n. differs from the other species of the genus Atelura in a smaller size, smaller number of ovipositor divisions, in the presence of apical sensory cones on the male parameres, which are absent in the other species of the genus, and in a fewer number of lateral pegs on urotergite X. The genus Nipponatelurina comprises two species (N. kurosai Mendes et Machida, 1994 and N. caucasica sp. n.). The distinguishing features of N. caucasica sp. n. include a significant number of short minute thin cilia on the head capsule, a longer ultimate segment of the maxillary palp, and a fewer number of setae at the posterior margin of urosternites IV–VII. Lepisma xylophila sp. n. differs from L. saccharinum and L. chlorosoma in the distribution of epidermic pigment and in the urotergites chaetom. Lepisma adygei sp. n. is most closely related to the synanthropic species L. saccharinum, but differs in the size of the body, color of scales on the upper surface of the body, and in the structure of the labial palps, urotergite X, ovipositor, and parameres.  相似文献
