Diagnosis. FEMALE. This female is easily recognizable by the medially fully interrupted bands of pale pubescence on T2 (apically) and T3 ( Fig. 7B ). Other supporting features, though not diagnostic, include oval spot of pale pubescence over vertex; three round spots of pale pubescence basally on T2; low transverse scutellar scale; black mesosomal sternum and darkened pronotal band; pygidium proportionately elongated, with subparallel sides and typically black, covered with fine, weakly divergent striae; mesosomal dorsum sub-horizontal ( Fig. 8D ); mandible with distal element externally convex towards apex, inner basal ridge curved inwards ( Figs. 6B, 6E ). Body length 5.3–8.5. MALE. Distinguished from other Smicromyrme by apically tridentate mandible, metasomal pattern (pale pubescence forms apical fringe on T1 and T2, full bands on T3–4, frequently with anterior notch on T2 apical band), clypeus dorsally concave with two forwards facing tubercles on anterior margin, and strongly infuscate wings, together with genitalia. Not covered in this paper.

Distribution. Europe: Portugal ( Fig. 4B ), Spain, France (south), Italy (Liguria, Tuscany, Lazio, Calabria, Sicily), Malta, Greece, Montenegro, Serbia; North Africa: Morocco, Algeria, Tunisia; Asia: Syria ( Lelej 2002; Pagliano & Strumia 2007; Pagliano et al. 2020).

Remarks. Smicromyrme fasciaticollis Spinola, 1843 ( Spain: Andalusia; Italy: Sicily, Lampedusa island; Malta; Pagliano & Strumia 2007), is sometimes considered a subspecies of S. partitus ; the females of both taxa are not safely distinguished in the absence of males. Two additional taxa in the Iberian Peninsula are currently treated as subspecies: Smicromyrme partitus obscurithorax (André, 1902) and S. p. propodealis ( Suárez, 1959) (e.g. Pagliano et al. 2020), but may represent chromatic forms.
