Figs 1B , 2 D-F, 4.

Type material. Holotype male RMBH Sph 0805: Tajikistan, Pamir Range, Surkhob River valley, ca. 8 km NW of Navobod village, altitude 1460 m, 39.0739° N, 70.0983° E, 22 June 2018, Spitsyn leg.

Reference COI barcode sequences. GenBank accession number MK887192 (holotype) .

Etymology. This subspecies is named in honor of Mr. Nozimdjon Mahmudov (Dushanbe, Tajikistan) who help us to collect the holotype.

Differential diagnosis (male). This subspecies could be distinguished from the other taxa in the genus by combination of the following characters: wing coloration creamy-white; postdiscal band is very broad and is located near the apex of the central cell connecting with the discal spot; valva elongated, narrow, tapering distally, without clear separation on the narrow distal and broad proximal parts; juxta very narrow, strongly sclerotized; saccus W-shaped.

Molecular diagnosis. This new subspecies differs from the other congeners with available sequences by one diagnostic nucleotide substitution in the COI gene fragment ( Table 1). The COI p-distance between the new subspecies and Eudiaphora turensis turensis is 0.9%.

Description. Male. Wingspan 34 mm, forewing length 19 mm ( Fig. 1B ). Head creamy-white, eye black. Antenna bipectinate, black. Labial palpus long (slightly longer than twice eye diameter), dark brown, straight. Proboscis reduced. Torax creamy-white, with elongated black scales on the tegula. Abdomen dark yellow, with black band on each tergite. Legs yellow, with black apex of the femur and black spots on the tarsus. Upperside of both wings creamy-white, the hindwing is slightly lighter than the forewing; fringe broad, creamy-white. Forewing with two small black basal spots, a broad subbasal black band, a group of five discal black spots, and a broad subdiscal band. Hindwing with a comma-shaped discal black spot. Underside of both wings creamy-white, with marking patterns similar to those on their upperside. Male genitalia. Tegumen elongated, broad; uncus broadly triangular, its apex rounded ( Fig. 2D ). Juxta very narrow, strongly sclerotized; saccus W-shaped ( Fig. 2E ). Valva elongated, narrow, tapering distally, without clear separation on the narrow distal and broad proximal parts ( Fig. 2D ). Aedeagus long, broad, vesica with weak, rather dense granulation ( Fig. 2F ). Female unknown.

Distribution. Known only from the type locality: ca. 8 km NW of Navobod village, Surkhob River valley, Pamir Range, Tajikistan ( Fig. 4 ).
