Diagnosis.

Body slender; head, mesosoma and the first and 4-6th metasomal segments uniformly red (Figs 4C, 5C); T1 pear-shape (Fig. 11C); T2 and T3 dark brown, longitudinally closely strigate, both tergites with distinct yellow bands and compact (dense) setal rows along the whole posterior margins (Fig. 12C); T6 laterally with relatively small but sharp teeth, a little spaced in the middle, posterior ones minute and rounded at the apex (Fig. 14C).

The new species may be confused with M. ezzati Gadallah & Soliman, 2014 (Egypt) (Fig. 15) in having the same body colour, T6 red with lateral teeth not excessively large and a little spaced in the middle, but differs from it by having body very slender, mesosoma striatopunctate (Fig. 9C) and T2 and T3 longitudinally strigate (Fig. 12C) (body robust, mesosoma densely punctate (Fig. 15B) and T2 and T3 ellipsoid punctate with ridges in between (Fig. 15C) in M. ezzati).

Description.

Female (Holotype). Body slender, 4.0 mm in length.

Colour (Figs 4C, 5C, 12C, 14C): Head including antenna, mesosoma, legs and the first and 4th -6th (except lateral margins of T6, including teeth, slightly brownish); metasomal segments as well as S2 red; T2 and T3 dark brown, both tergites with well-developed yellow bands along posterior margin that are widened medially; S3 reddish brown; maxillary and labial palpi yellow; mandible reddish brown, red basally; fore tibial spur red, mid and hind ones waxy white.

Pubescence (Figs 6C, 10C, 11C, 12C): Body including scape of antenna and legs clothed with scattered fine and erect white setae; face with scattered procumbent pale-golden setae, denser and inwardly directed on vertex, dorsum of mesosoma with similar but erect setae; posterior margin of T1-5 with row of dense silvery setae, directed towards middle.

Head (Figs 6C, 7C, 8C): In dorsal aspect scarcely wider than the maximal width of pronotum (about 1.1 ×), with thin occipital carina; face and vertex with scattered setiferous punctures, vertex broadly convex; gena and malar area nearly smooth; eye small, somewhat bulged laterally when seen in front or dorsal view, located above mid line between clypeus and vertex when seen in front view; distance between antennal tubercles about as long as tubercle length; malar space hardly longer than eye height (about 1.1 ×); scape of antenna about 2.5 × as long as F1; F1 as long as F2. Clypeus broad, with apical half nearly smooth and gently bent toward the mouth, basal part of clypeus with scattered setiferous punctures; mandible edentate.

Mesosoma (Figs 9C, 10C): Pronotum shallowly foveate dorsally, weakly rugose laterally, rectangular (about 1.65 × as wide as long at maximum width), with anterior margin gently declivous, humeral angle rounded and posterior margin broadly concave; remainder of mesosomal dorsum setiferous striatofoveate; posterior face of propodeum gently declivous, smooth and impunctate; mesopleuron superficially foveolate; metapleuron smooth above, and weakly transversely ridged below. Inner hind tibial spur about 0.65 × as long as hind related basitarsus.

Metasoma (Figs 11C, 12C, 13C, 14C): T1 pear-shape, as long as its maximal width, shallowly setiferous foveate; T2 semicircular, about 1.5 × as wide as long, with yellow band remarkably widened medially; T2 and T3 longitudinally strigate; ridges on T3 more regular and closer than those of T2; T4 and T5 posteriorly with row of very close ellipsoid punctures; T6 with weak, scattered and widely interrupted brown ridges, narrowly rounded at apex, laterally with small but sharp teeth, becoming minute towards apex. S2 and S3 smooth except laterally with scattered setiferous punctures, with row of long scattered setae along posterior margins; S4-5 smooth and shiny except posteriorly with row of setiferous punctures; hypopygium with setiferous punctures on posterior half.

Variation.

Some paratype specimens are longer, about 4.8-5.5 mm. In some specimens T6 slightly darker, yellow-brown; face with darker golden setae.

Distribution.

Saudi Arabia (Riyadh region).

Etymology.

The specific name ' Micatagla saudita ' is a Latinized adjective in the feminine gender derived from the country of the type locality, Saudi Arabia.
