Strumigenys tenuipilis

Bolton (2000) – Baroni Urbani (1971) lists a number of Italian localities for this species and Casevitz-Weulersse (1990) confirms its presence in Corsica. Its distribution appears to be more restricted that that of Strumigenys baudueri, and even where the two occur together tenuipilis seems much less common than baudueri.

Identification
A member of the Strumigenys baudueri-group.

Lapeva-Gjonova, & Ljobomirov (2020) - Although Strumigenys tenuipilis has been described by Emery (1915) as S. baudueri var. tenuipilis, it is well distinguished from Strumigenys baudueri by its clypeal hairs that are non-spatulate, directed anteriorly and distinctly curved apically. Additionally, it occurs in a wide variety of preserved natural habitats, whereas Strumigenys argiola is common in highly disturbed environments as well as urban and suburban open habitats (Holecová et al., 2015).

Distribution based on Regional Taxon Lists
Palaearctic Region: Andorra, Bulgaria, France, Greece, Iberian Peninsula, Italy, Malta, Morocco, Spain.

Nomenclature

 *  tenuipilis. Strumigenys baudueri var. tenuipilis Emery, 1915a: 264 (w.) ITALY. Combination in S. (Cephaloxys): Emery, 1916b: 131; in Smithistruma: Brown, 1948e: 105; in Pyramica: Bolton, 1999: 1673. Raised to species: Brown, 1953g: 132; in Strumigenys: Baroni Urbani & De Andrade, 2007: 129.

Worker
Bolton (2000) - TL 2.0-2.3, HL 0.56-0.62, HW 0.38-0.43, CI 67-71, ML 0.08-0.12, MI 15- 20, SL 0.27-0.31, SI 69-75, PW 0.23-0.25, AL 0.60-0.64 (10 measured).

Pilosity of clypeal dorsum in full-face view entirely of slender curved hairs that are narrowly spatulate through most of their length. In profile these hairs are elevated, directed anteriorly and at least in their apical halves are distinctly curved, arched, or even weakly hooked forward. Mediodorsally curved ground-pilosity between posterior margin of clypeus and highest point of vertex slender and simple, as are the principal curved hairs that project from the leading edge of the scape.

Type Material
