Abstract. The European species of the Hilara maura-group are revised. Three species are described as new to science, namely, H.nitidorella sp.n., H.discalis sp.n. (both temperate Central and Western Europe) and H.mauroides sp.n. (Caucasus, male only). A further five species, H.hybrida Collin, H.femorella Zetterstedt, H.sulcitarsis Strobl, H.tyrolensis Strobl and H.bartaki Straka are redescribed, and H.eumera Loew, 1873 becomes a new synonym of H.nitidula Zetterstedt, 1838. Seven lectotypes are designated. All IS European species are keyed, the main differential characters are illustrated, and additional data on biology and distribution are given. The Hilara maura-group is recognized as a monophyletic group within the genus, characterized by a set of apomorphous characters, and the hypothetical phylogenetic relationships of the species, classified into four natural complexes, are demonstrated.  相似文献

A new genus of cynipid oak gallwasp, Zapatella Pujade-Villar & Melika, gen. n. (Hymenoptera: Cynipidae: Cynipini), with two new species, Zapatella grahami Pujade-Villar & Melika, sp. n. and Zapatella nievesaldreyi Melika & Pujade-Villar, sp. n., is described from the Neotropics. Zapatella grahami,known only from the sexual generation,induces galls in acorns of Quercus costaricensis and is currently known only from Costa Rica. Zapatella nievesaldreyi, known only from the asexual generation, induces inconspicuous galls in twigs of Quercus humboldtii, and is known only from Colombia. Diagnostic characters for both new species are given in detail. Five Nearctic species are transferred from Callirhytis to Zapatella: Zapatella cryptica (Weld), comb. n., Zapatella herberti (Weld), comb. n., Zapatella oblata (Weld), comb. n., Zapatella quercusmedullae (Ashmead), comb. n.,Zapatella quercusphellos (Osten Sacken), comb. n. (= Zapatella quercussimilis (Bassett), syn. n.). A key based on adults for the species belonging to Zapatella is also given. Generic limits and morphological characteristics of Zapatella and closely related genera are discussed.  相似文献

This report deals with a group of ciliated protozoa with short ciliary bands found mainly in the cecum of black rhinoceros, Diceros bicornis (linnaeus, 1758), and white rhinoceros, Ceratotherium simum (Burchell, 1817) from southern Africa. A new genus, Rhinozeta, based on the sum total of the characteristics of seven new related species is described. The species described are R. rhinozeta n. sp., R. triciliata n. sp., R. caecalis n. sp., R. addoensis n. sp., R. cristata n. sp., R. multiplatus n. sp., and R. unilaminatus n. sp. The specific features of the new genus make it incompatible with any of the known families of the Order Entodiniomorphida containing the ciliates present in the digestive tract of herbivorous mammals. This merits the creation of a new family, the Rhinozetidae.  相似文献

Two new species of Dalyellidae, Dalyellia callvucurai n. sp. and Gieysztoria namuncurai n. sp., are described from temporary freshwater environments in central Buenos Aires Province, Argentina. The ultrastructure of the stylets of both species is also described. The new species of the genus Dalyellia is the second species of the genus found in the neotropics and the first whose stylet has been studied with scanning electron microscopy. Gieysztoria namuncurai n. sp. joins the seven species of the genus known in Argentina. The ultrastructural characteristics of the stylet place it in the Inaequales group, with complex stylets.  相似文献

Questidae is a poorly known polychaete family with many unusual characters, particularly with regard to its reproductive organs. Its taxonomic position remains uncertain, which can be partly referred to the limited material described to date. New material, mostly from shallow sublittoral sediments, shows that questids have a circummundane distribution. Questa Hartman, 1966 is revised to include Novaquesta Hobson, 1970 as a junior synonym. Eight species of questids are assigned to Questa , four of them are new to science: Questa bicirrata sp. n., Q. paucibranchiata sp. n., Q. mediterranea sp. n., and Q. riseri sp. n. Character patterns of the questid polychaetes described so far are cladistically analysed. The limitation of informative characters causes ambiguity in the most parsimonious reconstruction of the phylogeny of the family, and therefore, the Questidae is proposed to be classified as comprising only one genus.  相似文献

Five new species, Petrobius caucasicus sp. n., Trigoniophthalmus presimplex sp. n., T. divnogorski sp. n., T. kislovodski sp. n., and T. adigei sp. n. (Machilidae), are described from the Caucasus. A key to all the known species of the genus Trigoniophthalmus is given. Two subgenera (Trigoniophthalmus s. str., Trigoniocellus subgen. n.) in the genus Trigoniophthalmus are described. 2 + 2 retractile vesicles are present on abdominal segments II–IV in the species of Trigoniocellus subgen. n. and on II–V abdominal segments in Trigoniophthalmus s. str. Analysis of the evolution and phylogenetic relations between the species of the genus Trigoniophthalmus is performed for the first time. The formation of bristletails of the genus Trigoniophthalmus appears to occur in the Caucasian mountain province of the European area, from where they penetrated to the Central European mixed province and the Mediterranean subarea. Among the described species of the genus, T. kislovodski is distinguished by the greatest number of plesiomorphic states of morphological characters.  相似文献

A new species of Cochliopodium isolated from freshwater at Arabia Lake in Lithonia, GA, USA is described based on light microscopic morphology, fine structure, and molecular genetic evidence. Cochliopodium arabianum n. sp., previously labeled as “isolate Con1” in prior publications, has been shown to group within the genus Cochliopodium in our molecular phylogenetic analysis. Light microscopy and fine structure evidence indicates the new isolate not only shares characters of the genus but also unique distinctive features. Cochliopodium arabianum n. sp. is typically round when stationary; or oval to sometimes broadly flabellate or triangular in shape during locomotion, with average length of 35 μm and breadth of 51 μm. Fine structure evidence indicates C. arabianum n. sp. has tower‐like scales, lacking a terminal spine, sharing high similarity with its closest relative C. actinophorum. However, the scales of C. arabianum n. sp. are unique in height and the breadth of the base plate. Both morphological and molecular data, including SSU‐rDNA and COI, indicate that this new species falls in a clade sufficiently different from other species to suggest that it is a valid new species.  相似文献
