Meria concinna nov.sp.

Holotypus - Algeria = / Biskra 28 km S 30.V.80/, MZUF!

Paratypus - Algeria = / Biskra 28 km S 30.V.80/, MZUF!

Paratypus - Morocco = (2) / Morocco 10 km E. Guelmin 5.5.1995 M. Halada leg./, OLML.

Female (Holotype). Figs 9-13 . Measurements - body length: 11 mm.

Black, brown, ferruginous, creamy white.

Brown: mandibles; most of clypeus; scape and flagellum; tegulae; LaSt 2; veins of the wings; legs with X 1 darker and tarsi lighter; shadows on vertex and propleurae; all the mesosoma with 2 nd to 6 th sterna lighter than remainder.

Ferruginous: The whole of N 1 but apical posteroventral corner; Sc 1 and Sc 2 but narrow apical stripe which is brown.

Creamy white: two large lateral spots on 2 nd and 3 rd terga.

Brownish hair on the head and pronotum, whitish on the remainder of the body. Punctuation follows the standard within the genus. Remarkable wrinkles on the sides of the propodeal disk.

V a r i a b i l i t y: No noteworthy differences with holotype.

Male (Paratype). Figs 19-27 . Measurements- body length: 12.5 mm.

Black, brown, yellow.

Brown: tip of mandibles, veins (pterostigma is light brown); lateroterga are semitransparent light brown.

Yellow: most of clypeus and mandibles; tip of Tsa; two lateral stripes along foreborder and one preapical of N 1 disk; large spot on Es 2; and Lst 2; most of tegulae; tip and ventral femurs; most of tibiae and tarsi; apical stripe (2/5 their height, with an entire fore edge and widening at the sides) on 1 st to 6 th terga; lateral spots on 7 th terga; apical stripe with indented edge on 2 nd to 6 th sterna.

Punctuation on the head and mesosoma mostly as the same as in M. tripunctata; propodeal disk regularly sculptured but in the middle with a small smooth shining area just beyond sP; Em 3 and anteroventral lateral P regularly and densely wrinkled. Punctuation of metasoma very weak and sparse like in M. latifasciata. Hair covering underlying integument only on the Tsa and lateral propodeal disk.

Deep notch between Tsa. Thickness of the Secu stripe only about 1/3 the flagellomeri. Lamella along fore border of N 1 disk well evident medially but scarcely produced laterally. Fore (outer) surface of the mid femurs completely devoid of p and hair.

D i s c u s s i o n: The females looks very like M. sanguinicollis in general habitus and coloration. It can be known from the latter by the red Sc 2, more transversal head in frontal aspect (Ratio LA/A = 1.17 vs 1.14), larger N 1 disk (Ratio LA/ Am = 2 vs 1.5), wrink- les along lateral borders of propodeal disk, larger fenestra of pterostigma, different venation of the forewing with larger 1 st CSM and shorter 2 nd CD, different line of the gradulus on 2 nd tergum, no microreticulation on 6 th tergum.

The male looks very like to M. tripunctata, its genitalia too, from which differs because of the deeper notch between Tsa, more transversal 1 st, 2 nd,3 rd metameri, cuspis of the volsella not produced upward in lateral aspect and above all in having smooth, hairless fore surface of the median femur; M. tripunctata belongs to the group of palaearctic species having that regularly pitted and haired. From M. latifasaciata / M. laeta it differs greatly in the shape of the head, thickness of the Secu stripe, pronotum, wrinkled Em 3 and genitalia; from M. volvulus because of more slender flagellum and metasoma, shape of the head and pronotum, genitalia; from M. cylindrica in the shape of the head, width of the Secu stripe, pronotum, epipygium, genitalia and foresurface of the midfemur; from the supposed male of M. cephalotes in the shape of the head, pronotum, basal metameri and genitalia.

D i s t r i b u t i o n:NWAfrica.

E c o l o g y: Unknown.

D e r i v a t i o n o m i n i s: From the latin "concinnus" = graceful.
