Specimens of Asymphylodora perccotti sp. n. (Trematoda: Lissorchidae) were found in the esophagus of the freshwater fish Perccottus glenii (Odobantidae) taken from the Bolshaya Ussurka River Basin (Primorsky Region, Russian Southern Far East). The first intermediate host of this trematode is a gastropod, Parafossarulus manchouricus, and the secondary hosts are the same mollusk and Boreoelona ussuriensis. Specimens of the new species are similar to A. amnicolae identified by Stunkard in 1959, but the mature worms have larger suckers and shorter ceca. The cercariae of these species are distinguished by body, suckers and pharynx size. These organs in A. perccotti sp. n. are more than one-third larger than what is observed in A. amnicolae. In addition, the new species lacks the capacity for progenesis. Finally, the new species is unusual in that it resides in the fish esophagus instead of the intestine, as is common for most Asymphylodora species. Partial ribosomal DNA sequences and phylogenetic reconstruction sequence data indicate that these worms represent a new digenean species.  相似文献

Primorya gen.n. is described as a new genus of the flesh fly subfamily Paramacronychiinae, including the type species and sole member Primorya ussuriensis sp.n. from the Russian Far East. Arguments for erecting a new genus are obtained from a phylogenetic analysis of all paramacronychiine genera. Goniophyto suenagai (Kurahashi), comb.n. is transferred from Wohlfahrtiodes Villeneuve and included in a broadened concept of Goniophyto Townsend, and Agria cicadina (Kato) , comb.n. is transferred from Angiometopa Brauer & Bergenstamm. A key to all paramacronychiine genera is provided.  相似文献

ABSTRACT .
The previously monotypic Papuan genus Heterochorista Diakonoff, 1952 is revised and twenty-one species are recognized. Nikolaia Diakonoff, 1953 is synonymized, syn.n. with Heterochorista. The following six species are placed in new combination in Heterochorista: Nikolaia melanopsygma Diakonoff, N.inumbrata Diakonoff, N.aperta Diakonoff, Isochorista papuana Diakonoff, I.polysperma Diakonoff and Dicellitis chrysonetha Diakonoff. Thirteen new species are added to Heterochorista: acomata sp.n., rostrata sp.n., trivialis sp.n., ornata sp.n., prisca sp.n., punctulata sp.n., rufulimaculata sp.n., classeyiana sp.n., spinosa sp.n., signata sp.n., fulgens sp.n., nitida sp.n. and aura sp.n. A checklist and a key to species are provided, and adults and male and female genitalia are described and illustrated. The phylogeny of Heterochorista is outlined on the basis of a cladistic character analysis and the genus is referred to the base of the Sparganothini. The apomorphies characterizing this tribe are reviewed with regard to their phylogenetic significance and the relationship between Sparganothini, Archipini and Atterini is briefly discussed.  相似文献

Ten new species in three subgenera of Dicyrtoma are described from the Hawaiian Islands. Specimens were received from collections made on Hawaii, Maui, Kauai and Oahu. Species definitions are based on chaetotaxy of head, legs and the circumanal region. In addition, presence or absence of lateral spines (neosminthurid setae) on the parafurcular lobes may assist in grouping species within subgenera. Previous records of dicyrtomids from Hawaii include only one species, Ptenothrix ( Papaairioides ) daubia (Folsom). The following new species are described: Ptenothrix ( Ptenothrix ) hawaiicnaeis sp.n., Ptenothrix ( Papirioides ) kauaiensis sp.n., P. ( Papirioides ) serrata sp.n., Dicyrtoma ( Calvatomina ) sylvestratilis sp.n., D. ( Calvatomina ) brevifibra sp.n., D. ( Calvatomina ) tesselata sp.n., D. ( Calvatomina ) longidigita sp.n., D. ( Calvatomina ) bellingeri sp.n., D. ( Calvatomina ) madestris sp.n., and D. ( Calvatomina ) microdentata sp.n.  相似文献

Eight nematode species of the order Monhysterida are described from the East Flower Garden at 72 m depth in the north–western Gulf of Mexico. The material is from sandy and rocky bottom samples influenced or beyond the influence o f a sulphide–rich brine seep. Seven species are new to science: Monhystera anoxybiotica sp.n., Gonionchus intermedius sp.n., Theristus (Theristus) coplatus sp.n., Theristus (Theristus) rezaki sp.n., Xyala oxybiotica spa., Desmolaimoides thiobioticus gen. et sp.n. and Linhomoeus gittingsi sp.n. Specimens of a Linhomoeus species are also described. The species is probably new to science, but the available material only includes females and juveniles.  相似文献

ABSTRACT. Analysis of host plant data for the seventy-one species of Diaphorina shows the genus to be unusually polyphagous, the species developing on eighteen families of dicotyledonous angiosperms. Apart from the common Asian citrus pest, Diaphorina citri , a second citrus-feeding species is described and discussed. This species belongs to the amoena species-group which is defined and a key to nine of the ten included species is given. Seven new species are described: flavipennis sp.n. and nigripennis sp.n. from East Africa on Strychnos usambarensis; huila sp.n. from Angola on Ptaeroxylon obliquum; turned sp.n., from South Africa (host unknown); orantimina sp.n. from Madagascar (host unknown); auberti sp.n. from Comoro Islands on citrus trees; and bispinulata sp.n. from Madagascar (host unknown).  相似文献

The subgenus Neosynaptops Voss of Euops Schoenherr is revised. It contains two previously described species, E. cupreosplendens Macleay and E. viridiceps Voss, plus seven new ones: E. doertheae sp. n., E. gladiator sp. n., E. paraviridiceps sp. n., E. punctaticeps sp. n., E. similis sp. n., E. waigeoensis sp. n. and E. wapogae sp. n. A lectotype is designated for E. viridiceps Voss. The species are described and the characters relevant for their identification, especially the male genitalia, are illustrated. A key to the species is provided. Three distinct types of proventriculi found in species of Neosynaptops are illustrated. A cladistic analysis is performed which confirms the monophyly of Neosynaptops . The most important apomorphies are the punctate-rugose sculpture of the gena and the longitudinal costae on the ventral surface of the rostral base. The group is restricted to New Guinea and some small neighbouring islands.  相似文献

All species that have been described in Apicalia , except the type-species, are transferred to other eulimid genera. Three species earlier included in other genera and four new species are placed in Apicalia , viz. A. angulata sp.n. A, cicatricosa sp.n. A. echinasteri sp.n. (all three Queensland), and A. habei sp.n. (Japan). Those of which the hosts are known are all ectoparasites of asteroids. Two of the seven species previously included in Stilapex are excluded and four species earlier placed in other genera are transferred to Stilapex . The members of the latter genus are parasites of ophiuroids. Tropiometricola gen.n. is erected to include Stilifer sphaeroconcha Habe, a crinoid parasite. Parvioris gen.n. is described with Eulima fulvescens A. Adams as type species. A list of species described in eulimid genera and fitting Parvioris is given. P. australiensis sp.n. (W. Australia), P. blakeae sp.n. (Mauritius), P. mortoni sp.n. (Hong Kong), and P. noumeae sp.n. (New Caledonia) are described. Those species of which the host is known, are all ectoparasites of starfishes.  相似文献

Abstract.  The 'nudidrosophila' and 'ateledrosophila' species groups, formerly described as genera, are a relatively small and understudied part of the enormous Hawaiian Drosophila radiation. Only nine species were described previously. Here we revise the two groups, provide a key to males and females, and describe fully all species. The 'ateledrosophila' group now contains three species, D. diamphidia Hardy, D. papala sp.n. , and D. preapicula Hardy. The 28 species of the 'nudidrosophila' group are separated into five subgroups: 'hirtitibia' ( D. hirtitibia Hardy, D. konaensis sp.n. , D. mawaena sp.n. , and D. papaalai sp.n. ); 'kahania' ( D. kahania sp.n. and D. longipalpus sp.n. ); 'nudidrosophila' ( D. aenicta Hardy, D. amita Hardy, D. canavalia sp.n. , D. eximia Hardy, D. gemmula Hardy, D. kualapa sp.n. , D. lepidobregma Hardy, D. mahui sp.n. , D. malele sp.n. , D. panoanoa sp.n. , and D. poonia sp.n. ); 'okala' ( D. akoko sp.n. , D. kuhao sp.n. , D. makawao sp.n. , D. okala sp.n. , and D. panina sp.n. ); and 'velata' ( D. halapepe sp.n. , D. kauaiensis sp.n. , D. lauoho sp.n. , D. milolii sp.n. , D. pohaka sp.n. , and D. velata Hardy).  相似文献

The genus Phanoperla (=Dyaperla Banks, 1939) (Plecoptera: Perlidae: Perlini) is revised and generic diagnoses are provided for adults and larvae. Diagnostic and constitutive characters of the tribe Neoperlini are discussed, and Chinoperla Zwick, 1980, is shown to be the closest relative of Phanoperla. Many past misidentifications of Phanoperla species have been corrected by the use of characters recently recognized as important, namely the structure of the internal genitalia of male and female specimens and particularly the complex pattern of spines on the male penial sac made visible by eversion of this structure, and details of sculpturing of the egg chorion.
The following species of Phanoperla are recognized: amorpha sp.n.; anomala (Banks, 1939); bakeri (Banks, 1924); ceylonica Kawai, 1975; comuta sp.n.; flaveola (Klapálek, 1921), comb.n. ( =clarissa (Banks, 1913), syn.n.), (=Neoperla hageni Banks, 1920, syn.n.), (= N.consimilis Banks, 1924, syn.n.); guttata sp.n.; himalayana Zwick, 1977 (= siwalika Harper, 1977); limosa (Hagen, 1858); maculata sp.n.; maindroni (Navas, 1926), comb.n.; malayana sp.n.; minutissima (Enderlein, 1909); nana sp.n.; nervosa Banks, 1939; nuwara Kawai, 1975; omega sp.n.; pallipennis (Banks, 1938); parva sp.n.; pumilio (Klapálek, 1921), comb.n.; peniculus Kawai, 1969a; schmidi sp.n.; sertispina Jewett, 1975; srilanka sp.n.; sumatrae sp.n.; testacea (Hagen, 1858); wedda sp.n. P.claggi (Banks, 1938) is a nomen nudum.
All species are (re-)described and figured; all primary types have been examined. A key to species is provided. Most species can be assigned to one of seven species groups which are defined.
Phanoperla is endemic to the Oriental Region. Species groups are generally widespread, but individual species are in most cases known only from restricted areas.  相似文献

ORECTOLOBICESTUS N. G. (CESTODA: Tetraphyllidea) is erected for six cestode species parasitising bamboo sharks (Orectolobiformes: Chiloscyllium). Members of this genus differ from all other phyllobothriid genera in possessing modified maisiform spinitriches on their distal bothridial surfaces. In addition, they are easily recognised in that they share the following unique combination of characters: their vitelline fields are interrupted by the ovary, their necks are scutellate, and their bothridia bear an apical sucker and marginal loculi. Five new species of Orectolobicestus are described, including O. tyleri n. sp. from Chiloscyllium punctatum off Borneo, O. lorettae n. sp. from C. cf. punctatum off Australia, O. mukahensis n. sp. and O. kelleyae n. sp. from C. indicum off Borneo, and O. randyi n.sp. from C. hasselti also from off Borneo. In addition, Phyllobothrium chiloscyllii Subhapradha, 1955 is transferred to the new genus. O. chiloscyllii (Subhapradha, 1955) n. comb. is readily distinguished from all five new species in its greater total length. In addition to a number of proglottid features, O. kelleyae n. sp. and O. randyi n. sp. clearly differ from the other three new species in their possession of trifid, rather than fully serrate, spinitriches on their proximal bothridial surfaces. The latter two species conspicuously differ from one another in total number of proglottids (11-21 vs 27-38). O. tyleri n. sp. generally has fewer proglottids than O. lorrettae n. sp. (7-17 vs 13-23) and, like O. mukahensis n. sp., possesses scutes that are spathate rather than elongate. O. tyleri n. sp. is readily distinguished from O. mukahensis n. sp. in its possession of fewer proglottids (7-17 vs. 19-29). The five new species of Orectolobicestus share derived bothridial microthrix features with Phyllobothrium squali Yamaguti, 1952, Thysanocephalum sp., Orygmatobothrium sp., Ruhnkecestus Caira & Durkin, 2006 and species of Paraorygmatobothrium Ruhnke, 1994. Among these taxa, Orectolobicestus most closely resembles Paraorygmatobothrium and Ruhnkecestus in its vitelline fields being interrupted by the ovary and the possession of a scutellate neck.  相似文献
