Philbyella gnezdilovi View in CoL nov.sp.

M a t e r i a l: Holotype male: Morocco, Atlas Mts. S Marrakesh, Pass Tizi-Ouzla 10 km SW Asni, 1000 m asl, 18.5.1981, dry bush vegetation (FASMALP 81/87), R. Remane leg., in coll. OEKO . Paratypes: One male, Morocco, Atlas Mts. S Marrakesh, 10 km N Asni, near Tahanaoute, 900 m, 25.5.1981, dry bush vegetation (FASMALP 81/13), R. Remane leg., in coll. OEKO ; one female, Morocco, Tifrit 20 km N Agadir, 28.4.1998, gorge with shrubby vegetation ( MAR 98 View Materials /2), R. Remane leg., in coll. OEKO .

B o d y s i z e:Males 4.1-4.2mm,female 5.5mm.Onlybrachypterous specimens known.

D e s c r i p t i o n (see also Figs 5-6 View Fig 5 View Fig 6 , 7A, 7B View Fig 7 ): Metope less than 1.5 x longer than wide, broadest part before epistomal suture. Median keel present, sublateral keels missing, but a more or less distinct darker line present. Lateral margins of Metope slightly elevated. Postclypeus without median keel. Epistomal suture strongly curved. Junction between Metope and Vertex forming an rectangular angle in lateral view. Apical margin of vertex in dorsal view slighly convex. Vertex more than 3 times wider as medially long. Pronotum medially slightly longer than vertex. Mesonotum with three longitudinal keels.

Fore wings with fork of MP (sensu BOURGOIN et al. 2015) at 1/3 of the wing length and forks of ScP+RA with RP as well as form CuA1 and CuA 2 in the middle of the wing (see Fig 5D View Fig 5 ). Colouration of body incl. wings varying from dark brown with many small, light brown dots (as holotype) to straw-coloured with only very scattered darker areas.

Male anal segment large, apically with a semicircular lobe directed downwards, shaped like a inverse "u" in caudal view.

Basis of aedeagus without processes. In the middle, two pairs of spine-like processes arise: Ventrally a smaller one, straight, pointing straight cephalad (p 1 in Fig. 6 View Fig 6 ), and laterally a long s-shaped one (p 2 in Fig. 6 View Fig 6 ). Subapically, three pairs of more or less straight spines are present (p3, p4 and p 5 in Fig. 6 View Fig 6 ).

The genital styles are long, evenly curved and running into a blunt tip apically.

E t y m o l o g y: This very issid-like species is named in honor of the famous Russian Issidae specialist Vladimir Gnezdilov.

D i f f e r e n t i a l d i a g n o s i s: ThisisthesmallestNogodinidae species in the Western Palaearctic. In male genitalia, the shape of the lateral process (p 2 in Fig. 6 View Fig 6 ) of the aedeagus is unique.
