Comparative analysis of karyotypes of Chironomussolitus Linevich Erbaeva 1971 and Chironomusanthracinus Zetterstedt 1860 (Diptera Chironomidae) from East Siberia

摘要

A comparative chromosome banding analysis of Chironomus solitus Linevich & Erbaeva, 1971 and Chironomus anthracinus Zetterstedt, 1860 from East Siberia (Lakes Baikal, Gusinoe, Arakhley and Irkutsk Reservoir) showed close similarity of banding sequences. Chironomus solitus differs from Chironomus anthracinus in one species-specific sequence of arm B. Arms C (43%) and D (30%) had inversion banding sequences previously reported in Chironomus anthracinus The similarity of karyotypic features of Chironomus solitus and Chironomus anthracinus in combination with morphological features of larvae provide evidence in favour of including Chironomus solitus in the Chironomus anthracinus group of sibling species long with Chironomus reservatus Shobanov, 1997.
