Five new species are described:Eremostachys codonocalyx from NE. Iran (related toE. subspicata),E. stenocalycina from NE. Afghanistan (related toE. alberti andE. hissarica),E. salangensis from NE. Afghanistan (close toE. bamianica),E. freitagii from E. Afghanistan (similar but not closely related toE. vulnerans), andE. andersii from E. Afghanistan (similar but not closely related toE. vulnerans), andE. andersii from NE. Afghanistan of isolated systematic position.

In total, 366 birds representing 55 species in 24 families and eight orders, were examined for chewing lice (Phthiraptera: Amblycera, Ischnocera) in two high‐altitude localities in Yunnan Province, China. In Ailaoshan, almost all of the birds examined were resident passeriforms, of which 36% were parasitized by chewing lice. In Jinshanyakou, most birds were on migration, and included both passerine and non‐passerine birds. Of the passerine birds caught in Jinshanyakou, only one bird (0.7%) was parasitized by chewing lice. The prevalence of Myrsidea and Brueelia‐complex lice on birds caught in Ailaoshan was higher than in previous reports. Of the chewing lice identifiable to species level, three represent new records for China: Actornithophilus hoplopteri (Mjöberg, 1910), Maculinirmus ljosalfar Gustafsson & Bush, 2017 and Quadraceps sinensis Timmermann, 1954. In total, 17 new host records are included, of which we describe two as new species in the Brueelia‐complex: Guimaraesiella (Cicchinella) ailaoshanensis sp. nov. ex Schoeniparus dubius dubius (Hume, 1874) and G. (C.) montisodalis sp. nov. ex Fulvetta manipurensis tonkinensis Delacour & Jabouille, 1930.

Meloidogyne hispanica n. sp. is described and illustrated from specimens obtained from peach rootstock, Prunus persica silvestris Batsch, from the Seville district of Spain. The perineal pattern of the female is oval shaped to rectangular with low dorsal arch and often widely spaced lateral lines with fringe-like striae. The stylet, 14.1 μm long, has broad, distinctly set off knobs. Males have a high, rounded head cap that slopes posteriorly. Labial disc and medial lips are fused to form elongate lip structures. The robust styler, 23.5 μm long, has large, rounded knobs that are slightly set off from the shaft. Mean second-stage juveniles length is 392.6 μm. The truncate head region is generally not annulated. The distinctly rounded and raised labial disc and the crescent-shaped medial lips form dumbbell-shaped lip structures. The stylet, 11.1 μm long, has rounded, posteriorly sloping knobs. The slender tail, 46.4 μm long, has large irregular-sized annules in the posterior region and ends in a bluntly rounded tip. Tomato was a good host; tobacco, pepper, and watermelon were poor hosts; cotton and peanut were nonhosts. Meloidogyne hispanica n. sp. reproduces by mitotic parthenogenesis and has a somatic chromosome number of 2n = 33-36. The esterase pattern is unique among Meloidogyne species. 相似文献

Comparative morphological, karyological and chorological studies prove the distinctness of the SE European and Asiatic populations ofPulmonaria mollis s.l., to be treated asP. dacica (Figs. 4, 5).P. mollis s.str. is interpreted as a relatively young taxon, which probably has evolved from an older stock ofP. dacica ancestors during the Pleistocene (Figs. 6, 8) and might have migrated, perhaps with oak woodland communities, from SE to C. Europe. A similar evolution can be postulated for S—SE European dysploidP. rubra-carnica-stiriaca-vallarsae group; this may have involved still unknown tetraploids (P. carnica?, Fig. 7). This group is linked via the hypertriploid speciesP. vallarsae with theP. saccharata group and at least the eastern species of theP. australis group. The monotypic genusParaskevia apparently marks the earliest divergence from the common Tertiary ancestral stock (Fig. 8). It exhibits a tetraploid chromosome number (2n = 28) but has preserved the most primitive characters. — Some comments on the systematics and nomenclature ofP. australis andParaskevia are added. 相似文献

In samples from 56 populations of Cardamine amara, representing four diploid subspecies (subspp. amara, opicii, balcanica, and pyrenaea) and two tetraploid subspecies (subspp. austriaca and olotensis) from different parts of the European distribution area, four enzyme systems with 23 alleles were studied. These data, together
with previous morphological and karyological data, suggest that the distribution and variation pattern within the species
was strongly influenced by the last glacial period and postglacial migrations. Cardamine amara subsp. pyrenaea is monomorphic for a unique allele, and subsp. balcanica has a unique allele, too which, however, is not fixed in all populations of the taxon. Both taxa seem to be relic ones, although
otherwise subsp. balcanica in respect of allelic spectrum much resembles subsp. amara. The other two diploid subspecies, subsp. amara and subsp. opicii, are not characterised by presence of unique alleles but differ in allele frequencies. The two tetraploid subspecies have
different evolutionary histories. C. amara subsp. austriaca seems to be an autopolyploid derivative of subsp. amara which colonised open space offered by retreating glaciers in the Eastern Alps. C. amara subsp. olotensis from the Iberian Peninsula represents most probably a polyploid of preglacial time.
