H. kuldschensis group

According to Schmid & Botosaneanu (1966) this group contains species with characters with symmetrical male anterior claws, male apicodorsal lobe of segment IX present, male preanal appendages small, male anal sclerite long and mobile, phallic apparatus complete, and male maxillary palps thicker than in species of the H. tibetana group.

Subgroups of the H. kuldschensis group

This group has been further divided into two subgroups which can be easily separated from each other.

1. Males.. .................................................................................................................................................................. 2

— Females. ................................................................................................................................................................ 3

2. Preanal appendages present. ................................................................................... H. kuldschensis subgroup

— Preanal appendages absent. ......................................................................................... H. angnorbui subgroup

3. Segment VIII completely divided into tergum and sternum. ............................. H. kuldschensis subgroup

— Segment VIII partly divided into tergum and sternum. ......................................... H. angnorbui subgroup

Indian species of the H. kuldschensis subgroup

This subgroup includes 9 Indian species: H. bhagirathi Schmid, 1963 ; H. dolmasampa Schmid, 1963 ; H. gyamo Schmid, 1963 ; H. lungma Schmid, 1963 ; H. malenanda Schmid, 1963 ; H. schmidi sp. n.; H. todma Schmid, 1963 ; H. yatrawalla Schmid, 1966 , and H. yongma Schmid, 1963 . The male of H. schmidi sp. n. is unknown.
