Remarks
— The male from Uttarakhand generally matches the description of
Neoatractides tashiwangmoi
, a species described on basis of a single female collected in a stream in
Bhutan
at an altitude of
539 m
(
Pešić
et al
. 2022a
). In
India
, a single male was collected in a sandy/bouldary stream (
Fig. 2
) at an altitude of
908 m
together with
Sperchon gracilipalpis
Lundblad, 1941
, and three other torrenticolid species, i.e.,
Monatractides
cf.
oxystomus
(K. Viets, 1945)
,
Torrenticola kumari
Pešić & Smit, 2020
and
Torrenticola birmana
(Lundblad, 1941)
(see
Pešić
et al
. 2022b
in press).
