Chironomus species PK6

Probably another member of the C. flaviplumus group.

Adult and Pupa not currently known.

Fourth instar larva: A small-medium plumosus-type.  Head capsule with gular region and fronto-clypeus pale.

Cytology: Four polytene chromosomes with the pseudothummi-cytocomplex combination BF, CD, AE, G.
Nucleolus terminal on arm G, which may be unpaired in this region.  Arm G also with two well developed BRs.
Polymorphism in arms A and C.

Arm A1:    1 - 2c, 11 - 7, 12, 3 - 2d, 6 - 4, 13 - 19                                             as A1 of species SS
Arm A2:    Inversion of approx distal half of arm, bringing " olive" near distal end
Arm B1:    Puff about 1/3 from centromere, with dark bands distal                  as sp.SS
Arm C1:    As species SS and large inv. c.f. striatipennis
Arm C2:    Small inversion of about 6 bands just near distal end of arm. Arm D1:    Differs by simple inversion from species SS
Arm E1:    1 - 2c, 8b - 6, 3 - 2d, 8 - 9, 4 - 5, 12a - 10, 12b - 13                 inv3d-12b from luridus, etc
Arm F1:    Inverted c.f. species SS?

Found:    India - Jammu & Kashmir: Kabeer colony, Jammu; Deoli Village.
                Pakistan (BOLD).

This species is close to, but not identical with, the Chironomus species (C. sp. SS) of Sumitra Saxena (1995).

DNA Sequence
DNA BARCODE suggests it is probably another member of the C. flaviplumus-group.
    Probable conspecific specimen in BOLD cannot be accessed for Bin number.
