Native range: India: Bihar, Jammu & Kashmir, Manipur (first state-level record), and Uttarakhand; Nepal; and Myanmar ( Nesemann et al. 2007; Bolotov et al. 2022b; Khan et al. 2024) ( Figure 5 View Figure 5 ).

Ecological notes: This species is considered a facultative snail-associated leech that may occur in the mantle cavity of freshwater gastropods.

Taxonomic comments: Nesemann et al. (2007) described two new Alboglossiphonia species from India and Nepal, that is, A. kashiensis Nesemann, 2007 and A. pahariensis . New data presented in this study reveal that A. pahariensis is characterized by a high level of morphological variability and that A. kashiensis may represent an intraspecific variation of A. pahariensis . The dark-colored specimens from Manipur ( Figure 1 View Figure 1 A-B), also having some degree of phylogenetic distinctiveness, may belong to a specific ecological or geographic race (see Discussion for detail).
