| chromosomal evidence for a new cryptic species of black fly in the <i>simulium</i> <i>praelargum</i> complex (diptera: simuliidae) from west bengal, india. | analyses of polytene chromosomes revealed a new cryptic species of black fly, simulium praelargum "il", in the simulium (nevermania) feuerborni group from darjeeling, west bengal, india. this new species occurred sympatrically with two other previously recognized species in the s. praelargum complex: simulium praelargum datta sensu stricto and simulium praelargum "iiil-1.2". chromosome arms is, iis, iil, and iiis of the new species showed no differences in banding patterns, compared with the seq ... | 2017 | 28610135 |
| heterochromatin and sibling species of simulium praelargum s.l. (diptera: simuliidae). | cytological descriptions are given for two sympatric sibling species, simulium praelargum iiil-st and simulium praelargum iiil-1.2, from darjeeling, west bengal, india. sibling iiil-1.2 differs from iiil-st by a two step fixed included inversion (iiil-1.2) found on the long arm of chromosome iii. both siblings possess heterochromatinized iiis polytene chromosome ends, while iiil-1.2 is unique within the simuliidae in that it exhibits a very large enhanced chromocentre that persists in normal som ... | 2014 | 25005610 |
