Stylascalaphus fabiani Mészáros & Ábrahám, 2005: 103 . Type locality: Pakistan (Islamabad).

Diagnosis. Based on original description by Needham (1909) for Stylascalaphus obscurus and by Mészáros & Ábrahám (2005) for Stylascalaphus fabiani , the following combination of characters have been assigned for distinguishing these two morphologically similar species at the present time: a medium sized species with forewing length 28.0–29.0 mm; legs dark brown; pterostigma light ochreous, with three dark brown crossveins; abdominal terga dark brown with a median longitudinal yellow stripe, tergum 1 with long black setae. However, in S. obscurus the forewing length is about 23.0 mm; the legs are yellowish; the wings have a reddish pterostigma, with four crossveins; and the abdominal terga is brown, with tergum 1 covered with long white setae.

Distribution. Pakistan (Islamabad Capital Territory: Gilgit-Baltistan Territory: District Gilgit, Bagroth Valley, Karakoram Mts., South Himalaya Mts.; Khyber Pakhtunkhawa province: District Mansehra, Kaghan Valley); Iran, Turkey (Adiyaman) ( Mészáros & Ábrahám 2005; Dobosz & Ábrahám 2007; Oswald 2020).
