Type locality: Algeria, "Daya, province d'Oran" ( Fairmaire 1879) .

Type series. Lectotype ( Fig. 30 ): ♀, "orchesioides / Fairm. / Daya , Oran / Bedel / typ." [hw], " Syntypus " [red label, printed], "coll. L. v. Heyden / DEI Eberswalde" (printed), " Lectotypus ♀ / Choleva / orchesioides Fairmaire /, P. M. GIACHINO & / D. Vailati des. 1992" [red label, printed] ( SDEI). We have found four specimens in the general collection of the MNHN that should be considered paralectotypes, with data: (1) 1 ♀, " Choleva / orchesioides / Frm. Daya" [hw Fairmaire], " MUSEUM PARIS / COLL. L. FAIRMAIRE 1906" [green label, printed], " TYPE " [red label, printed], " PARALECTOTYPUS [printed] / Choleva / orchesioides [hw]" [red label], (coll. générale in MNHN) ( Fig. 31 ); (2) 1 ♀, " Choleva / orchesioÏdes / Fairm. type / Daya" [hw, Fairmaire], " MUSEUM PARIS / COLL. ABEILLE DE PERRIN / 1919" [green label, printed], " TYPE " [printed in red], "Daya" [hw Jeannel], " PARALECTOTYPUS [printed] / Choleva / orchesioides [hw]" [red label], (coll. générale MNHN) ( Fig. 32 ); (3&4) 2 ♀♀ on the same pin, " MUSEUM PARIS / COLL. ABEILLE DE PERRIN / 1919" [green label, printed], "Daya" [hw Jeannel], " PARALECTOTYPUS [printed] / Choleva / orchesioides [hw]" [red label] (coll. générale in MNHN) ( Fig. 33 ).

Diagnosis. The species is characterised by: parameres simple, apex acute, only slightly turned outwards ( Fig. 13 ); apex of median lobe roughly pentagonal ( Fig. 5 ). The most similar species seems to be S. brusteli sp. n. (see the description of this species above).

Remarks. The type series of S. orchesioides is divided between the SDEI (lectotype) and the MNHN (four paralectotypes). All five specimens are females, so males of the species had to be identified from non-typical material. We consider that the male specimen figured by Jeannel (1936) from Ammi-Moussa (a locality ca. 80 km east of Daya, the type locality) belongs to this species. This specimen and a microscopic slide with its dissected aedeagus are deposited in the general collection of the MNHN; the slide is labelled with Jeannel's manuscript handwritting " Hormosacus / tenuipes Peyer. / orchesioides Frm. / Ammi-moussa", "org. cop. [= organe copulateur] ♂ ". The same preparation has the aedeagus of a specimen of S. tenuipes from the same locality. Note: A specimen figured by Giachino & Vailati (1993) as S. orchesioides is from Djebel Babor, some 600 km east of Daya, a considerable distance from the type locality, and representing a different species ( S. pulchellus , see below).

Distribution ( Fig. 38 ; Appendix). Algeria (Tell Atlas) ( Fairmaire 1879; Reitter 1885; Jeannel 1936; Giachino & Vailati 1993; Perreau 2000, 2004; Salgado et al. 2008). The records from the Iberian Peninsula, Fuente (1925) and Seabra (1943) for Portugal, and Giachino & Vailati (1993) for Spain, are unreliable; it seems likely that they should be referred to S. gracilis (see Discussion below). According to Giachino & Vailati (1993), the record of S. orchesioides from continental Italy by Jeannel (1936) (" Abruzzes: Gran Sasso, une femelle (Schatzmayr!)") is doubtful. However, this record was confirmed by newly obtained material from different provinces in continental Italy by Fabbri & Zoia (1996) and Giachino & Vailati (2000, 2007), as well as specimens in the SMNS (see Appdenxi), still identified as S. orchesioides . These records likely correspond to S. pulchellus (P.M. Giachino, personal communication 2018; see below under S. pulchellus ). The same happens with all the records from the Aurès mountains in Algeria and Tunisia ( Jeannel 1936) and the Eastern half of Algeria ( Giachino 1985). The records from the Moroccan Rif ( Jeannel 1936) may correspond to S. brusteli sp. n., but the identity of those from the Middle Atlas, also in Morocco ( Giachino & Vailati 1993), is unknown.
