This revision deals with the Zygothrica samoaensis species group, which includes 15 species, five of which are described as new to science. Two synonymies are proposed: Z. vietnamensis Grimaldi, 1990, as a junior synonym of Z. flavofinira Takada, 1976, and Z. britannia Grimaldi, 1990, as a junior synonym of Z. malaysiana Grimaldi, 1990. The samoaensis group is divided into three species subgroups: (i) the samoaensis subgroup, consisting of nine species, including a new species, Z. australiaensis sp. nov.; (ii) the fijiana subgroup of Z. fijiana Takada, 1976, and two new species, Z. triscutellaris sp. nov. and Z. bicornigera sp. nov.; and (iii) the leptorostra subgroup of Z. leptorostra Grimaldi, 1990, and two new species, Z. pimacula sp. nov. and Z. quintamaculata sp. nov. Supplementary information on geographic distribution is provided for some species, as well as a key to all species of the samoaensis group. Zygothrica kokodana Grimaldi, 1990, and Z. paleovitta Grimaldi, 1990, have closer affinity with the hirticornis and the quadrivittata species groups, respectively, and so are moved to the corresponding genus Hirtodrosophila. 相似文献

Three new species of Mya Linné are described from Greenland. Mya eideri sp. nov. is figured and compared with boreal and fossil species with which it has been confused, and the known distribution
of the species is indicated. The validity in Recent faunas of the fossil species M. pseudoarenaria and M. uddevallensis is discussed; two new Recent species, M. neoovata sp. nov. and M. neouddevallensis sp. nov., from Ikka Fjord, southwest Greenland, and Scoresbysund, East Greenland, respectively, are described for Recent
material of the comparable two fossil taxa.

Three new species of microfungi belonging to the genus Penicillium Link ex Fries are described and illustrated. All but one have been isolated from the atmosphere of las Palmas, capital city of the island of Gran Canaria (Canary Islands, Spain). They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new species: Penicillium hispanicum sp. nov., Penicillium grancanariae sp. nov., and Penicillium palmensis sp. nov. 相似文献

In a survey on heterostigmatic mites (Acari: Prostigmata: Heterostigmata) associated with insects including ants in northwestern Iran, two new species of myrmecophilous mites of the genus Scutacarus (Acari: Scutacaridae) were found. They are S. shajariani sp. nov. phoretic on Tetramorium sp. (Hymenoptera: Formicidae) and S. ebermanni sp. nov. phoretic on Messor sp. The mentioned new species belong to groups of species with reduced setae e and h2, and no setae 4b, respectively. These two new species are described and illustrated, and world keys are provided for respective species groups. 相似文献

The Jenynsia lineata species complex comprises J. lineata from Montevideo, Uruguay and Jenynsia multidentata, from coastal basins of Brazil, Uruguay and Argentina up to 1200 m a.s.l. Taxonomic divisions within this group were tested using three different species delimitation methods, which found the two existing names to be synonyms and revealed a new cryptic species. Jenynsia darwini sp. nov. is distinguished from all congeners by having a unique combination of character states, including the shape of the dorsal postcleithrum (three times higher than wide v. less than two times higher than wide) and female colour pattern in the half of the caudal peduncle with rows of chromatophores segmented in unaligned spots (v. aligned spots forming lines). The new species also differs from J. lineata by having 26 nucleotide substitutions in the mitochondrial gene cytochrome c oxidase I (coI). Phylogenetic analysis of the genus based on morphological characters proposed by previous studies corroborates monophyly of the subgenera Plesiojenynsia and Jenynsia, with the new species being allocated to the subgenus Jenynsia as the sister group of J. lineata. 相似文献

The alderfly genus Sialis is the most species‐rich group of the family Sialidae. However, discovery of new Sialis species is becoming difficult because of previous good faunal exploration. In this paper, we describe two new Sialis species from the southern part of East Asia, S. australis and S. jiyuni, based on materials from historical and recent collections. These two species are closely related to the insular species S. kumejimae and are among the early diverged species within Sialis. Presently, 32 species of Sialis are recorded from Asia. A key to all the Sialis species from Asia is provided. 相似文献

Summary Three new species of Acanthaceae, Lepidagathis pseudoaristata Ensermu, Acanthopale aethio-germanica Ensermu, and Rhinacanthus mucronatus Ensermu, are described from Ethiopia. The three species are illustrated and their distributions mapped. The three new species
are also compared to their presumed closest relatives. L. pseudoaristata is restricted to the Bale and Sidamo Regions, A. aethio-germanica is more widely distributed in Ethiopia occurring in the Kefa, Arsi, Sidamo and Bale Regions, and R. mucronatus is a local endemic restricted to the Borana area in the Sidamo Region. The conservation status of each species is also assessed. 相似文献

A new species of Nitrosococcus is described. It resembles Nitrosococcus oceanus in shape, size, and ultrastructure of the cells. However, the new species has a more pronounced salt requirement, corresponding to its natural habitats. Two strains were isolated from a salt lake in Saudi Arabia and a salt lagoon in the Mediterranean Sea, respectively. In contrast to N. oceanus, both isolates of the new species were unable to utilize urea as ammonia source. Both species also differed in gelelectrophoretic cell protein patterns. The name N. halophilus is proposed. 相似文献
