Key to female Smicromyrme of the Iberian Peninsula

(unknown for S. ferdinandi , S. matritensis , S. merceti , S. metanotalis and S. opistomelas ; not confirmed for S. suberratus )

1. T5 with full band of pale pubescence. [Scutellar scale large and elongate (ca. 2 × broader than long), shaped as a dorsally arcuate trapezium, with well formed convergent sides and apically truncate; this structure is approached only by some specimens of S. sulcisius Invrea ]................................................ S. ceballosi Suárez, 1959 (species incertae sedis)

- T5 with mostly black pubescence. [Scutellar scale different, with no elongated sides formed (if scutellar scale similar, metasomal pattern different)]..................................................................................... 2

2. Pronotum not darkened (rarely weakly darker brownish anteriorly, never black). [T2 without basolateral spots of pale pubescence (only sparse setae present at most)]....................................................................... 3

- Pronotum with black transverse band. [T2 with or without basolateral spots of pale pubescence]...................... 4

3. Pygidium with striae subparallel to the longitudinal axis. Scutellar scale relatively broad (e.g. ca. one sixth of mesosoma width; Petersen 1988). Dorsum of mesosoma sub-horizontal (lateral view). T2 with apical band of pale pubescence uniformly narrow. [Vertex with or without pale recumbent pubescence]........................................................................................... ‘complex S. (Smicromyrme) rufipes ’ [sensu Schmid-Egger & Schmidt 2021, 2022]

- Pygidium with divergent striae. Scutellar scale relatively narrow (e.g. ca. one eighth of mesosoma width; Petersen 1988). Dorsum of mesosoma angled towards scutellar scale (lateral view). T2 with apical band of pale pubescence medially broader. [Vertex with pale recumbent pubescence]............ S. (Smicromyrme) ruficollis ( Fabricius, 1793) [sensu Petersen 1988]

4. Mandible with distal element externally straight and elongate; basal groove and inner basal ridge approximately straight; basal portion proportionately short. Mesosoma with dorsal mid-line approximately straight, slanted towards scutellar scale (lateral view). [Mesosoma elongate, trapezoidal. T2 with medially enlarged apical band and T3 with full band of pale pubescence, both typically continuous. T2 laterally with or without well defined spots of pale pubescence].................................................................................................... S. (Eremotilla) sulcisius Invrea, 1955

- Mandible with distal element externally convex towards apex and not notably elongate; basal groove and inner basal ridge notably curved inwards; basal portion proportionately long. Mesosoma with dorsal mid-line weakly convex, with dorsum sub-horizontal (lateral view). [Band of T3 may be apicomedially weakly narrower, or partially to fully interrupted]........... 5

5. T2 basolaterally without or with weakly defined spots of pale pubescence (insipient or absent in dorsal view). Clypeus with subapical tubercle on each anterolateral corner of lower half. Scutellar scale narrow, small and inconspicuous. [Pygidium basally widened, oval. Mandible robust, not elongate]........... S. plantourianus Schwartz, 1986 (species incertae sedis)

- T2 basolaterally with two well defined oval spots of pale pubescence, one on each side (always visible in dorsal view). Clypeus without subapical tubercles on lower half. Scutellar scale not large, but well developed. [Pygidium elongate, may be basally widened and oval. Mandible more slender, more elongate]..................................................... 6

6. T2 with medially enlarged continuous broad apical band and T3 with full band of pale pubescence apicomedially variably narrowed. Pygidium typically subtriangular........................ S. suarezi Matias , sp. nov. (species incertae sedis)

- T2 with apical band and T3 with band of pale pubescence, both medially fully interrupted by black pubescence. Pygidium typically elongate, subparallel sided.................................................... S. partitus ( Klug, 1835) and S. fasciaticollis ( Spinola, 1843) [females of both species currently not clearly distinguishable] (species incertae sedis)
