Propodeal posterior face gently declivous, smooth and impunctate. Propleuron faintly punctured, with some incomplete longitudinal separated ridges posteriorly; mesopleuron foveate-reticulate; metapleuron smooth. Hind tibial spurs about equal in length.

Metasoma. T1 widened posteriorly (pear-shaped), as long as its maximal width (Fig. 16), with some dispersed punctures hidden behind hairs; T2 with ellipsoid foveae separated by longitudinal ridges (Fig. 17); T3 finely and closely striated longitudinally; T6 (pygidium) subtriangular, with longitudinal interrupted widely spaced carinae, bordered laterally with small sharp teeth that progressively reduce in size and become blunt distally, apical ones rounded (Figs 24, 25). Metasomal sternites smooth, with some scattered, erect fine hairs in the middle longitudinally.

Micatagla pseudorainerii is nearest to Micatagla rainerii Pagliano, 2002 which is found in Namibia, and the two species are distinguished by the following characters:

The name pseudorainerii refers to the similarity of this species to Micatagla rainerii.

Scape of antenna 2.35× as long as F1, gently and evenly convex from above; flagellomeres polished, F1 scarcely longer than F2, F2 as long as F3, F2–7 flattened beneath.

Pronotum 0.4× as long as its maximal width, with anterior face abruptly declivous, humeral angle gently rounded and posterior margin broadly concave; dorsally deeply foveate-reticulate; horizontally carinate laterally; remainder of mesosomal dorsum foveate-striate. Propodeal posterior face gently declivous and impunctate. Mesopleuron deeply foveate-reticulate; metapleuron faintly horizontally carinate. Mesosternum strongly bidentate in front of hind coxae. Inner hind tibial spur long (0.85× as long as basal tarsomere).

Metasoma. T1 (Fig. 22) widened posteriorly (pear-shaped), as long as its maximal width, densely foveate, abruptly declivous along posterior rim; T2 semicircular, 0.6× as long as wide, strongly petiolate anteriorly; T3 narrowed anteriorly forming a constriction with T2; T2 and T3 with ellipsoid foveae separated by longitudinal ridges (Fig. 23), foveae on T3 slimmer than those on T2, ridges on apical fourth of T3 fine and closer to each other than elsewhere; T6 (pygidium) subtriangular, with longitudinal interrupted widely spaced carinae, bordered laterally with small sharp teeth that progressively reduce in size and become blunt distally, apical ones rounded (Fig. 24). S1 smooth, transversely carinate basally; S2 deeply punctate-reticulate (impunctate on anterior declivity and posteromedially); S3 densely punctate laterally, impunctate medially; S4 and S5 with few scattered punctures; S2–5 with a row of punctures along their apical margins.

The specific name originates from Wadi Allaqi (Aswan, southern Egypt), the type locality.

This species is named in honour of the late Prof. Yahia Ezzat (the professor of the first author).
