Diagnosis (From Pont & Meier, 2002):

Adult male recognised by the remarkable form and colour of the mid tarsomeres (Fig. 101). Females recognised by the absence of postpronotal setae, entirely pruinose katepisternum, and partly yellow legs; it is most similar to paludosa, but can be reliably distinguished by the characters given in the key.



(From Ozerov, 2005)
annulipes Meigen, 1826: 292 (Sepsis). Type locality: not stated; Lectotype ♂, by designation of Pont in Pont and Meier, 2002: 64, in NHMW.

brunicosa Robineau-Desvoidy, 1830: 745 (Nemopoda). Type locality: Saint-Sauveur (FRANCE); Holotype ♀ or Syntypes ♀ ♀, presumed destroyed.

varipes Meigen, 1838: 351 (Nemopoda). Type locality: "Baiern " (GERMANY: Bavaria); Holotype ♀, in MNHNP.

marginata Hoffmeister, 1844: 13 (Sepsis). Type locality: not stated [GERMANY: Hessen]; Holotype ♂, not located and presumed destroyed.

crassiseta Duda, 1926a: 33, 72 [as variety of annulipes] (Enicita). Type locality: Chamonix (FRANCE); Lectotype ♀, by designation of Ozerov, 1997a: 479, in ZMHUB.

(From Pont & Meier, 2002)
Sepsis annulipes was described without the locality, number or sex given, ‘in dem Museum des Hrn. v. Winthem in Hamburg’. Pont has seen 4 ♂ syntypes in Naturhistorisches Museum, Vienna, Austria, which were also seen by Duda (1926: 72). Each is labelled ‘annulipes [handwritten] / Coll. Winthem [printed]’, each is in excellent condition, and each is annulipes as currently understood.
One has an additional old label ‘annulipes’. Pont has labelled this ♂ and designates it herewith as lectotype, and the remaining 3 ♂ as paralectotypes.
One ♂ in MNHNP (Muséum National d’Histoire Naturelle,Paris, France.), Meigen collection no. 2246 (see also Becker, 1902: 230), also seen by Pont, cannot be a syntype since it is labelled by Meigen ‘Sepsis annulipes Baiern’. Although badly damaged, it can be recognised as Themira annulipes
