Diagnosis. FEMALE. The following characteristics are diagnostic of this species: mandible with basal portion short and distal element externally straight and elongate, inner basal ridge nearly straight to weakly sinuate, not curved inwards ( Fig. 6C ); mesosoma trapezoidal and typically elongate; mesosomal dorsum slanted towards propodeum with characteristic wedge profile ( Fig. 8F ); scutellar scale broad and well developed; apical band of T2 medially acute with weakly concave sides; pale wide spot of pale pubescence over vertex acute over frons; T1 weakly elongate dorsally; antenna with elongate F1; metasoma most frequently with three basal spots of pale pubescence ( Fig. 7C ), but lateral spots can be small and not visible dorsally; tuft of black setae frequently present posterior to the scutellar scale, sometimes absent, or replaced by similar tuft of pale setae. Body length 4.5–9.7 mm. MALE. Distinguished from other Smicromyrme by combination of apically bidentate mandible, metasomal pattern (pale pubescence forms apical fringe on T1 and T2, and full bands on T3–4), very dark tegula, clypeus shape (dorsally flat with straight apical margin) and sub-hyaline wings, together with genitalia. Not covered in this paper.

Distribution. Europe: Portugal ( Fig. 4C ), Spain (including Mallorca island and Andalusia), France ( Corsica), Italy (Liguria, Piedmont, Emilia-Romagna, Veneto, Tuscany, Lazio, Molise, Basilicata, Calabria, Sicily, Sardinia), Romania ( Lelej 2002; Pagliano & Strumia 2007; Baldock 2015; Baldock et al. 2020; Pagliano et al. 2020; Parejo-Pulido et al. 2023).

Remarks. This species would be determined as ‘ Smicromyrme pusilla ’ using the key by Giner Marí (1944). Given its presence in NW Italy and in the Iberian Peninsula, it may be expected to occur in France along the Mediterranean (only known from Corsica).
