Strigamia acuminata ( Leach, 1815 )


Strigamia acuminata ( Leach, 1815)  

Synonyms: Geophilus subtilis C.L. Koch, 1838   ; Linotaenia rosulans C.L. Koch, 1847   ; Geophilus sanguineus Gervais, 1847   ; Scolioplanes variabilis Verhoeff, 1895   ; Scolioplanes engadinus banaticus Verhoeff, 1935   .

Nominal subspecies: S. acuminata microdon ( Attems, 1904)   ; S. acuminata brevidentata ( Verhoeff, 1928)   ; S. acuminata italica ( Verhoeff, 1928)   ; S. acuminata pachypus ( Verhoeff, 1935)   .

Taxonomic notes. Described originally as a species of Geophilus   , it was subsequently cited under different genera, including Linotaenia   and Scolioplanes   . It has been classified in Strigamia   since Crabill (1953). Different varieties and subspecies were recognized, mainly by Verhoeff (1928, 1935), but their validity was sometimes questioned though not definitively rejected ( Schubart 1967; Würmli 1972; Stoev 1997). Its name has been occasionally misspelled as “ Linotaenia attenuatus   ” ( Chamberlin 1911)

Geophilus subtilis   , Linotaenia rosulans   and Geophilus sanguineus   were synonymized under S. acuminata   first tentatively by Bergsøe & Meinert (1866) and Meinert (1870), then definitively by Plateau (1872).

Scolioplanes variabilis   was introduced by Verhoeff (1895) to indicate a putatively variable species that, in his opinion, had been separated incorrectly into two species, namely S. acuminata Leach   and S. crassipes C.L. Koch. In   his concept, S. variabilis   comprised three subspecies, which he called S. variabilis acuminata   , S. variabilis crassipes   and S. variabilis carniolensis Verhoeff   (currently a subspecies of S. crassipes   ; see below). Verhoeff’s opinion was followed only by a few authors, and only in part, and eventually abandoned by him. The species name S. variabilis   was completely ignored in subsequent literature, apart from being listed among the synonyms of S. crassipes   by Matic (1972). Actually, S. variabilis   should be costrued as a junior synonym of S. acuminata   , because the latter should have been recognised as the valid name for Verhoeff’s composite species, according to the principle of priority (I.C.Z.N. 1999: art. 72.9).

Scolioplanes engadinus banaticus   was described by Verhoeff (1935) and rarely cited by subsequent authors, until Matic (1972) listed it among the synonyms of S. engadina   . However, Verhoeff (1935) acknowledged that it is very similar to S. acuminata   and also gave a range of variation in the number of trunk segments that corresponds to that of S. acuminata   but not to that of the nominotypical subspecies of S. engadina   . S. engadinus banaticus   is recognized here as a junior synonym of S. acuminata   (new synonymy).

Distribution: most of continental Europe, from the Iberian peninsula to the Caucasus and Volga basin; also Great Britain and Sicily. It has been reported as introduced to some localities in the eastern part of North America. Published records from the western part of North America and Japan need confirmation because of probable confusion with S. chionophila   , which has been sometimes considered a synonym of S. acuminata   (see under S. chionophila   ). A vague citation for North Africa is probably erroneus (see under Discussion).
