Philbyella ainsefra View in CoL nov.sp.

M a t e r i a l: Holotype male: Algeria, Ain-Sefra (Oran), L. Bleuse, 6.7.1896, in coll. MNHN . Paratypes: One male, Ain-Sefra ( Oran), L. Bleuse, 6.1896, in HNHM, two females (one macropterous, one brachypterous) from Ain-Sefra ( Oran), L. Bleuse, 6.1896 and 6.7.1896, both in MNHN, and a brachypterous female from Ain-Sefra (collection Chobaut , collected by M. Bleuse) in HNHM ; Female with left wing (except for Clavus) missing, Mékalis (Oran), L. Bleuse, 16.5.1896, in MNHN. Another macropterous male is kept in MNHN, labelled "Figuig", "coll E. Bergevin ", " Issidius rotundiceps Leth. ", "Perse Figuig (Sud-Oranais)" [Figuig is a little oasis town in southeastern Morocco, 370 km S Ouida ] .

B o d y s i z e: Macropterous males 8.0- 8.3 mm, brachypterous males 5.6 mm; Macropterous female 8.7 mm long, brachypterous female 6.2-6.7 mm.

D e s c r i p t i o n (see also Figs 2-4 View Fig 2 View Fig 3 View Fig 4 ): Metope about 1.5 x longer than wide, sides slightly convex, median keel present, sublateral keels missing, lateral margins elevated. Postclypeus without median keel. Head in lateral view only slightly produced, distance from compound eye to the junction of metope/vertex only 1.5 x longer than from ocellus to the lateral margin of metope.

Vertex in dorsal view apically slightly produced, forming an obtuse angle. Vertex 2.4 times as wide as medially long. Pronotum medially slightly longer than vertex. its anterior margin strongly convex. Mesonotum with three longitudinal keels. Body straw-coloured, some specimens spotted with darker brown markings.

Wing venation as in other species of the genus. Fore wings in macropterous specimens hyaline with dark markings mainly along costal border and at the tip of the wing. Cells often with dark spots in the middle (see Fig 2 View Fig 2 and 3D View Fig 3 ).

Male anal segment basally slender in lateral view, apically broad with three large lobes: A caudal one, pointing ventrocadad, and long lateral lobes pointing ventrad. Basis of aedeagus on each side with a bifurcate process: The inner part is flattened dorsoventrally, with a spine orientated caudally, the outer part is flattened laterally and ends in a long process strongly curved upwards (p 1 in Fig 4 View Fig 4 ). Aedeagus ventrally in the middle of its length with a slender, straight spine (p 2 in Fig 4 View Fig 4 ) on each side and longer, s-shaped spines subapically (p 4 in Fig 4 View Fig 4 ). Dorsolaterally, a long and slender, evenly curved spine is present on each side (p 3 in Fig 4 View Fig 4 ). Genital styles long, apically strongly bent dorsocephalad.

Etymology: The name is derived from the type locality of the species.

D i f f e r e n t i a l d i a g n o s i s: This species is easily distinguishable from all other Philbyella species by the shape of the anal tube with its three large lobes. Furthermore, the number and arrangement of lateral spines of the aedeagus and the sphape of the genital styles are characteristic.
