Larva morphology and karyotype ofCladopelma viridula(Diptera, Chironomidae)

Comparative analysis of karyotypes of Chironomus solitus Linevich & Erbaeva, 1971 and Chironomus anthracinus Zetterstedt, 1860 (Diptera, Chironomidae) from East Siberia

“…Most of the chromosomal arms, A, D, E and F, have identical banding sequences, and a similar structure of arm G. The principal distinctive features of Chironomus solitus karyotype are the species-specific p’solB1 sequence and the absence of a nucleolus in arm F. Previous investigators (Belyanina 1979, Kiknadze et al 1991, 1996, Shobanov 1996, Petrova and Rakisheva 2003, Kiknadze et al 2005) reported a low level of chromosome polymorphisms in Chironomus anthracinus . Analysis of the populations with standard banding sequences from Lakes Gusinoe and Arakhley also confirmed these observations.…”

“…For instance, AR of Chironomus solitus (3.8) is most closely related to Chironomus anthracinus (4.14–4.43) from the European part (Shobanov 1996), and Chironomus anthracinus from East Siberia (5.0) – to Chironomus reservatus (4.8–5.6) (Shobanov 1997). Further research into metamorphosis of these species should be conducted to make reliable conclusions.…”

“…4.7.1 software. Mapping of arms A, C, D, E, and F of Chironomus anthracinus chromosomes was performed according to Kiknadze et al (2005) based on piger-standard (Keyl 1962, Devai et al 1989), while standard map of Chironomus plumosus suggested by Shobanov (1994, 1996) was used for mapping of arm B. Symbols designating banding sequences are as follow: distribution areas marked by p’ for Palearctic, n’ for Nearctic, and h’ for Holarctic zoogeographical regions (Kiknadze et al 2005) and followed by abbreviated species name (sol), arm designation (A) and banding sequence number–p’solx1 (in homozygote–p’solA1.1).…”

“…The first data were reported by Bukhteeva (1979); later, banding chromosome patterns and polymorphisms were described (Proviz 2009). Karyological analysis was made of Chironomus anthracinus from many Palearctic and Nearctic regions (Belyanina 1983; Kiknadze et al 1991, 1996; Shobanov 1996; Petrova and Rakisheva 2003; Kiknadze et al 2005). In East Siberia, karyotypes of larvae from Lake Shchuchie (Buryatia) were briefly reported by Bukhteeva (1979, 1980).…”
