The subgenus Bombus s. str. is represented by two valid species from Indian Himalayan region viz., Bombus jacobsoni- Skorikov and Bombus tunicatus- Smith. Both species of bumblebees are widely distributed and plays a very significant role in conserving the highland ecosystems. The species including the representatives of each caste, viz., queens, workers and males were collected from different habitats of Indian Himalayan region. Sixteen morphological parameters of this sub-genus covering 2 species viz., B. jacobsoni and B. tunicatus were investigated and measured relating to their body size, tongue length and antennae, number of hamuli, fore wings, hind wings and legs. Later on, total measurements were evaluated to know the differences for the identification of their different castes viz., queen, worker and males.

Later on, total measurements were evaluated to know the differences for identifying their different castes viz., queen, worker and male. Data generated from total measurements of all castes of two species of bumblebees indicate significant morphometric differences. Present studies will thoroughly help in identification of different castes of Bombus jacobsoni and Bombus tunicatus and equally support in understanding the classification of bumblebees.om total measurements of all castes of two species of bumblebees indicate significant morphometric differences.
