Six species of the genus Eumonhystera, one of which is new to science, are described from bottom samples of Lake Tana and two associated rivers, River Abbay and R. Gelda, Ethiopia. E. geraerti n.sp. can be identified by being the only species in the genus that combines very posteriorly positioned vulva [V% = 68.2 ± 0.7 (67.3–69.3)] with very anteriorly positioned amphids (Amph-ABE/LRW = 0.8). The other five species encountered, E. dispar (Bastian, 1865) Andrássy, 1981, E. filiformis (Bastian, 1865) Andrássy, 1981, E. pseudobulbosa (von Daday, 1896) Andrássy, 1981, E. mwerazii (Meyl, 1957) Andrássy, 1981, and E. vulgaris (de Man, 1880), Andrássy, 1981, are described in detail. The identities of some of the already described populations of E. dispar, E. filiformis and E. vulgaris are questioned and clearer and better ways of defining each of these three species are suggested. A peritrophic-like membrane on the outer side of the brush-border of the intestine of E. mwerazii, a species reported here for the first time out of its type locality, is reported. Also, scanning electronmicrographs of sectioned and entire specimens of E. mwerazii are presented. All species are reported from Ethiopia for the first time.  相似文献

Abstract Some types of E. Asian sawfly species described by Forsius in 1931 are examined. One new species is described based on the paratypes of a species described by Forsius: Eutomostethus forsiusi sp. nov. Three new combinations are provided: Nesoselandria annamitica (Forsius 1931) comb. nov., Birmindia gracilis (Forsius 1931) comb. nov. and Eutomostethus sikkimensis (Forsius 1931), comb. nov., two synonyms are proposed: Birmindia gracilis (Forsius 1931) =Birmindia albipes Malaise 1947, syn. nov. and Indotaxonus tricoloricornis (Konow, 1898) =Conaspidia dubiosa Forsius 1931, syn. nov.  相似文献

Five species of Elasmus are described from Russia as new to science (E. altaicus sp. n., E. ekaterinae sp. n. and E. maritimus sp. n.), Turkmenistan (E. turkmenicus sp. n.), and Mongolia (E. emeljanovi sp. n.). E. nikolskayae Myartseva et Dzhanokmen, 1989 is redescribed. Elasmus obesoceratus Trjapitzin, 1979 is downgraded to a synonym to Elasmus rufiventris Ferrière, 1947. Sixteen species are recorded for the first time for the fauna of Russia, six for Tajikistan and Turkmenistan, five for Azerbaijan and Kazakhstan, four for Ukraine and Mongolia, two for Moldova, Georgia, Armenia, Uzbekistan, China, and South Korea, and also new single records are given for Poland, Slovakia, Abkhazia, Afghanistan, and Iran. New hosts are recorded for seven species: E. flabellatus Fonsocolombe, E. longiclava Graham, E. nudus (Nees), E. platyedrae Ferrière, E. schmitti Ruschka, E. steffani Viggiani, and E. westwoodi Giraud. A key to twenty-six species of Elasmus is compiled.  相似文献

Erysimum damirliense, a new species of Brassicaceae from Zanjan and Ardebil provinces (northwest Iran) is described and illustrated. The new species resembles E. uncinatifolium and E. elbrusense, but is easily recognized by its life form, basal leaf margin, indumentum of cauline leaves, number of flowers in the main raceme, fruit width and style length. Phylogenetic analysis of internal transcribed spacer (ITS) DNA sequences confirm that the new species is distinct from morphologically similar species.  相似文献

As a result of studies of material of Ecdyonurus from Spain, nymphs and adults of two new species, E. baeticus sp. n. and E. olgae sp. n., are described. Three species described by Navás must be considered as nomina dubia (E. diversus Navás, 1923, E. excelsus Navás, 1927 and E. fluminum var. speciosus Navás, 1915). Variability in adults of E. venosus is figured and discussed.  相似文献
