Type locality. Algérie, massif du Zaccar (see lectotype designation below) .

Type series. Lectotype (by present designation) ( Fig. 36 ): ♂, "Mt Zackar / fin nov. 99 " [= end of November 1899] [hw in red], " tenuitarsis / type ♂ " [hw Peyerimhoff], " LECTOTYPUS / Anemadus / tenuipes Peyer. 1917 / Fresneda et al. des. 2017" [red label, hw Fresneda] (coll. Peyerimhoff in MNHN), aedeagus mounted on a transparent card on the same pin (coll. Peyerimhoff in MNHN) . Paralectotypes: 1 ♂, "crête du / Djurdjura" [printed], " Anemadus / tenuitarsis / Peyer. type" [hw Peyerimhoff], aedeagus mounted on a transparent card on the same pin. 3 exs. on the same pin (2 ♀♀ + 1 ex. eaten in part by Anthrenus ), "Garh [?] el Kef / [?]1,XII,05" [hw] / "massif des / mouzaia" [printed], " Anemadus / tenuitarsis / Peyer. types" [hw Peyerimhoff ]. 1 ex.: "Les Mouzaïa / fin mars 05 [?]" [hw] . 1 ♂ "En Nouaduir[?] / Ouarsenis / avril 1914 " [hw], " Speonemadus / orchesioides Fairmaire / Fresneda det. 2017". All paralectotypes in coll. Peyerimhoff ( MNHN) and with an additional label " PARALECTOTYPUS / Anemadus / tenuipes Peyer. 1917 / Fresneda et al. des. 2017" [red label, hw Fresneda]. Note: The male paralectotype labelled "En Nouaduir [?] / Ouarsenis / avril 1914 " actually belongs to S. orchesioides .

Diagnosis. Length 2.8–2.9 mm; elytra strongly narrowing towards apex; external face of protibia granulated, with setae inserted in small tubercles; antennomeres VIII-XI longer than wide; parameres wide, robust and sinuated, with notch at external margin and acuminate apex ( Fig. 16 ); apex of median lobe simple, regularly rounded, without expansion ( Fig. 8 ). Molecular data show that S. tenuipes is the sister species of S. gracilis . The aedeagi of the two species have a similar structure ( Figs 7, 8 ), although the apex of the median lobe of S. gracilis has an elongated expansion and the parameres are more slender, with the distal part straight.

Remarks. There is some morphological variability among the specimens forming the type series of S. tenuipes . The aedeagus of one specimen from "crête du Djurdjura" (MNHN, coll. Peyerimhoff, labelled as "type" by the hand of Peyerimhoff), even if corresponding to the general morphology of the lectotype ( Fig. 9 ), has distinctly less sinuate parameres, the notch on the external side of the parameres is less marked (only clearly visible in the left paramere), the apical section of the paramere is shorter than that of the lectotype from Zaccar, the apex of the median lobe of the aedeagus is more rounded, almost truncated. Other studied specimens from Ifri Semedane, Ammi-Moussa, Mouzaia (a possible but dubious syntype from the general collection of the MNHN, not considered here as part of the type series), plus those from the Akfadou and Gerrouch forests ( Giachino & Vailati 1993: figs 320, 321), have an aedeagus identical to that of the lectotype. Being found in a single specimen we have considered these differences to be intraspecific variation, but future studies may demonstrate that the Ifri Semedane population represent a separate species.

Distribution ( Fig. 38 ; Appendix). Found in the Tell Atlas, from the wilayah [= province] of Jijel in the northeast of Algeria, close to Oran in the west ( Jeannel 1936; Szymczakowski 1970; Giachino 1985; Giachino & Vailati 1993). It has also been recorded from the Middle and High Atlas in Morocco ( Peyerimhoff 1917), although the identity of these specimens is doubtful.
