A cladistic analysis of sixty erythracarine species is presented and used to justify recent nomenclatorial changes to the classification of erythracarine genera. Erythracarinae is redescribed, and a new diagnosis for the subfamily and a key to the included genera are presented. Neotarsolarcus is recognized as a junior synonym of Tarsolarkus, which is recorded for the first time from North America. A new genus, Pedidromus, with six new species (P. agitatus sp.n. P. curiosus sp.n., P. durongensis sp.n., P. peliculus sp.n., P. pilotrix sp.n., P. velox sp.n.) is described.  相似文献

Six new Diplopeltula species are described: D. pulchra sp.n., D. belgica sp.n., D. striolata sp.n. and D. curta sp.n. (Southern Bight of the North Sea), D. nellyae sp.n. and S. pumila sp.n. (New Caledonia). Diplopeltula indica Gerlach, 1962 is redescribed from Guadeloupe (FWI). Based on the examination of these seven Diplopeltula species, the genus has been reappraised. The systematic position of the other genera of the Diplopeltidae Filipjev, 1918 is also discussed. Diplopeltoides Gerlach, 1962 is moved from the Aegialoalaimidae Lorenzen, 1981 to the Diplopeltidae.  相似文献

Two new genera of giant ostracods Lacrimicypris n. gen. and Repandocypris n. gen. from Australia are described and eight new species:L. kumbar n. sp., R. austinensis n. sp., R. gleneagles n. sp., Mytilocypris coolcalalaya n. sp., Australocypris bennetti n. sp., A. beaumonti n. sp., A. mongerensis n. sp. and Caboncypris kondininensis n. sp. The number of known Australian genera and species of giant ostracods are now 6 and 21, respectively. Keys to genera and species are provided: all species can be distinguished using the hemipenis and male first leg. The usefulness of the bursa copulatrix as a species-level taxonomic character is highlighted. Most of the species described in this paper occur in salt lakes and existing ecological information on Western Australian species, as well as the distributions of all species, are summarized. Western Australia has a particularly rich halobiont fauna but current explanations relating richness of the halobiont fauna to the widespread occurrence of salt lakes appear incomplete. Australocypris bennetti is unusual in that it is frequently found at pH < 4. Its morphology differs slightly in acidic and alkaline waters.  相似文献

Two new genera, ten new species, and two new subspecies: Uvaroviella izerskyi sp. n., U. morona sp. n., U. ucayali sp. n., U. pastaza sp. n., U. affinis sp. n., U. bolivia sp. n., U. bora atalaya subsp. n., Kevanacla orientalis contraria subsp. n., Peruacla solitaria gen. et sp. n., Ecuadoracla propria gen. et sp. n., Adelosgryllus spurius sp. n., and A. phaeocephalus sp. n. are described. The tribe Paragryllini is divided into three subtribes: Paragryllina Desutter, 1988 stat. n., Neoaclina Desutter, 1988 stat. n., and Strogulomorphina Desutter 1988, stat. n. The composition of the genera Uvaroviella Chop. and Neoacla Desutter is discussed. The species from Costa Rica and the Antilles are supposed to belong to these genera and subgenera. New synonymy [U. trinidadi Gorochov, 2007 = U. enodos Otte et Perez-Gelabert, 2009, syn. n. and N. multivenosa (Chopard, 1937) = Selvacla choreutes Otte, 2006, syn. n.] is proposed.  相似文献

Scripta 1(3–4): 121–138, 1972.–The collection of Pipunculidae made in Burma by Rene Malaise contained approximately forty species in five genera and four subgenera and is probably a thorough sampling of the species which occur in the Kambaiti area of N.E. Burma. Eleven new species are being described: Dorylomorpha latifrons sp.n., D. stenozona sp.n., Pipunculus (Cephalops) dolosus sp.n., P. (Cephalops) fimbriatus sp.n., P. (Cephalops) validus sp.n., P. (Cephalosphaera) reduncus sp.n., P. (Cephalosphaera) tingens sp.n., P. (Eudorylas) burmanicus sp.n., P. (Eudorylas) colossus sp.n., P. (Eudorylas) giganteus sp.n., and P. (Eudorylas) malaisei sp.n. Several other species, probably new ones, are indicated but not being described until further specimens can be studied. The majority of the species are new records for Burma.  相似文献

To more confidently assess phylogenetic relationships among astome ciliates, we obtained small subunit (SSU) rRNA sequences from nine species distributed in six genera and three families: Almophrya bivacuolata, Eudrilophrya complanata, Metaracoelophrya sp. 1, Metaracoelophrya sp. 2, Metaracoelophrya intermedia, Metaradiophrya sp., Njinella prolifera, Paraclausilocola constricta n. gen., n. sp., and Paraclausilocola elongata n. sp. The two new species in the proposed new clausilocolid genus Paraclausilocola n. gen. are astomes with no attachment apparatus, two files of contractile vacuoles, and an arc-like anterior suture that has differentiations of thigmotactic ciliature on the anterior ends of the left kineties of the upper surface. Phylogenetic analyses were undertaken using neighbor-joining, Bayesian inference, maximum likelihood, and maximum parsimony. The nine species of astomes formed a strongly supported clade, showing the subclass Astomatia to be monophyletic and a weakly supported sister clade to the scuticociliates. There were two strongly supported clades within the astomes. However, genera assigned to the same family were found in different clades, and genera assigned to the same order were found in both clades. Thus, astome taxa appear to be paraphyletic when morphology is used to assign species to genera.  相似文献

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.  相似文献
