Atkinsoniella fistular sp. nov.

Figs. 2 A–D, 3A–F

Length. Male: 5.9mm; female: 6.2mm.

Dark brown in appearance dorsally. Crown with two large black spots connecting medially and extending to face, basal margin with large black lobe, interrupted at anterior lobes by pale yellowish transverse streak not extending to eyes, anterior margin of crown around eyes pale; face with brown spots, postclypeus with dark brown transverse streaks interrupted medially, anteclypeus with brown spots except pale margins, gena with lateral margins brown; pronotum black with discontinuous transverse wavy pale yellowish line near anterior margin; scutellum black with lateral margins brown; forewings dark brown. Crown subangularly produced, wider than pronotum; distance between eyes more than median length of crown; pronotum transversally shagreen, posterior margin with slight constriction medially.

Pygofer lobe broadly rounded posteriorly, posterior margin convex, with few macrosetae at posterior half, ventral process sickle-shaped and extending posterodorsad, wider at base with group of stubby microsetae, gradually narrowing toward middle part, then taking curve and becoming slender with dentate acute apex in lateral view; connective ‘T’-shaped with short stem, area around arms and apex of manubrium membranous; style with base membranous and narrowing towards apex dorsally, medially broad, apophysis finger-like, slightly curved dorsad; subgenital plates subtriangular with uniseriate macrosetae and scattered microsetae, inner margin slightly convex, without median constriction; aedeagus tubular with large gonopore at apex on ventral margin, without well separated lobes, with slight sclerotization near apex ventrally, curved anterodorsad in lateral view.

Material Examined. Holotype: ♂, Pakistan, Azad Jammu & Kashmir, Rawlakot , 1638m, 8 August 2017, Coll. Hassan Naveed. Paratypes: 1♂, 1♀, same data as Holotype .

Remarks. This new species is similar to A. nigripennis Yang et Li, 1999 in color pattern but can be readily differentiated from latter by following characteristics: crown and facial markings; pygofer lobe with rounded posterior margin; ventral pygofer process with dorsal margin apically serrated; style with base narrowing towards apex; tubular aedeagus shape; aedeagal shaft not ‘S’-shaped laterally.

Etymology. The specific epithet “ fistular ” refers to the tube-like aedeagal shaft.
