Specimen Labels


The commonest and most widely distributed species of the sparse West Palaearctic dacetine fauna (Bolton, 2000), this species is known from all Mediterranean countries except those in the southeast (Borowiec, 2014; Taheri & Reyes-Lopez, 2023). In Morocco, it has been reported once in Agadir, fallen in a pool (Bolton, 2000; Cagniant, 2006), and once in the Rif, extracted from a soil sample (Taheri & Reyes-López, 2015). Its cryptic lifestyle (Braschler, 2002; Marko, 2008) makes it difficult to be detected. (Taheri & Reyes-Lopez, 2023)


Bolton (2000) - A member of the Strumigenys baudueri-group. S. baudueri is very closely related to two other species with a Mediterranean distribution, Strumigenys tenuipilis and Strumigenys tenuissima. The three are remarkably similar but each has a different clothing of clypeal pilosity. Brown (1953a) wondered if the three were discrete species or merely expressions of a single variable species. Material examined during this survey implies that the clypeal differences are consistent and that species rank may properly be applied to them all.

Keys including this Species


Bolton (2000) - Even relatively early (Andre, 1883; Emery, 1916) this species had been recorded from the Mediterranean territories of France, Italy, Corsica, Sardinia, Tunisia and Turkey. Many more records are now known from some of these territories (Baroni Urbani, 1971; Casevitz-Weulersse, 1990) and the known range of baudueri now also includes Croatia and Hungary (Brown, 1953a), Spain (Collingwood & Yarrow, 1969), the Balkans (Agosti & Collingwood, 1987), Armenia (Arakelian & Dlussky, 1991) and Switzerland (Borcard, Borcard, et al., 1997 [which was misidentified as Strumigenys argiola; see Baroni Urbani, 1998]).

Bolton (2000) - TL 1.9-2.3, HL 0.55-0.62, HW 0.40-0.43, CI 66-72, ML 0.09-0.11, MI 15-18, SL 0.30-0.32, SI 71-76, PW 0.24-0.26, AL 0.58-0.64 (10 measured).

Pilosity of clypeal dorsum in full-face view entirely of short wide hairs that are broadly spatulate to spoon-shaped and very distinctive. In profile these hairs are all subreclinate to reclinate, directed anteriorly, and more or less parallel with the surface of the dorsum, none is obviously elevated. Mediodorsally curved ground-pilosity between posterior margin of clypeus and highest point of vertex conspicuously spatulate, as are the principal curved hairs that project from the leading edge of the scape. In some samples funicular segments 2 and 3 may be fused, and 3 may also be partially or mostly fused to 4.
