Abstract
Karyological studies were carried out on a population of Stictochironomus sp. from Gadigarh locality of Jammu region, J&K state, India. The work attempts to examine the polytene chromosomes of the species. The investigated species possesses the usual four polytene chromosomes with the arm combination AB, CD, EF and G. The karyotype of Stictochironomus sp. is being elucidated with a photomap of polytene chromosome complement (2n=8) is presented with the description of detailed banding pattern in each chromosome. The results are compared with three other worked out species of the same genus viz., Stictochironomus n. sp.1, Stictochironomus n. sp.2 and Stictochironomus marmoreus.

Key words: Chironomidae, cytophotomap, karyology, polytene chromosomes, Stictochironomus sp.
