| characterization of internal transcribed spacer (its1)-its2 region of ribosomal rna gene from 25 species of culicoides biting midges (diptera: ceratopogonidae) in japan. | we determined nucleotide sequences of the nuclear rdna internal transcribed spacer (its)1-5.8s-its2a-2s-its2 region in 103 individuals of 25 culicoides species (diptera: ceratopogonidae) from 11 locations in japan. ribosomal rna genes, 5.8s and 2s rdna, were highly conserved among the species with few variations. the its2a region showed length variation among species. both its1 and its2 showed highly varied sequences among species. the noticeable indel regions among its1 sequences are present in ... | 2009 | 19769041 |
| six new species and males of some species of japanese culicoides (diptera: ceratopogonidae). | culicoides (avaritia) pastus sp.n., c.(a.) wadai sp.n., c. (culicoides) cylindratus sp. n., c. (oecacta) insularis sp.n., c. (o.) nunomemoguri sp.n. and c. (trithecoides) longicercus sp.n. are described as new species. hitherto unknown males of c. (c.) aterinervis, tokunaga, c. (beltanmyia) japonicus arnaud, c. (o.) wakuensis mcdonald, bolinguit et lu and c. (t.) matsuzawai tokunaga are described and the male of c. (a.) jacobsoni macfie is redescribed. | 1980 | 7432546 |
