Distribution.

This species is currently known only from the study area.

Remarks.

The above recorded specimens of Altajosoma sp. are most similar to Altajosoma bakurovi bakurovi (Shear, 1990) in some details of gonopod structure, i.e. in the shape of colpocoxites of the posterior gonopods and in particular in their distal parts, but the colpocoxites are a little bit narrower in the newly found species compared to A. bakurovi bakurovi. These specimens also differ significantly in the shape of the large posterior angiocoxal processes.
