Chironomus Species 4

Chironomus species 4
This may be C. flaviplumus ty. B
(based on Kabeer Colony IN.6.1 photos from Pragya Khanna)

Adult and Pupa: Not currently known

Fourth instar larva: Morphology not known

Cytology: Four polytene chromosomes with the pseudothummi-cytocomplex combination BF, CD, AE, G.  Arm G with three obvious BRs, one near distal end not always developed, but no obvious nucleolus.  Nucleolus possibly on arm F, but this is not clear.  Polymorphism in arms A, C and G.

Arm A1:
Arm A2:
Arm B1: Puff (gp 7) slightly proximal of centre of arm with dark bands (gp 8) distal
Arm C1: Inverted near distal end compared to striatipennis
Arm C2: Inversion of about distal two thirds of the arm.
Arm D1:
Arm E1:
Arm F1: Bands 7,8,9 near distal end; nucleolus in group 20.
Arm G1: may be similar to C. flaviplumus B.
Arm G2: possibly complex inversion.


Polytene hcromosomes of C. species 4

Found:  INDIA - Jammu: Kabeer colony (32.70°N, 75.00°E).

Probably equivalent to C. flaviplumus Ty. B.
