Type series. Lectotype (by present designation) ( Fig. 34 ): ♂, " pulchellus / m. [= mihi] Sicilien " [hw Reitter], "coll. Reitter " [printed], " HOLOTYPUS 1884 / Anemadus / pulchellus Reitter " [red label, printed], " LECTOTYPUS / Anemadus / pulchellus Reitter, 1885 / Fresneda et al. des. 2018" [red label, printed] ( HNHM); aedeagus mounted on a glue card on the same pin . Paralectotypes ( Fig. 35 ): four specimens mounted on a single pin with five cards (one of the specimens is lost), " A. pulchellus / m. Sicilien " [hw Reitter ], "155" [printed], " TYPE " [red label, printed], " MUSEUM PARIS / ( COLL. E. REITTER) / A. GROUVELLE 1913" [printed], " pulchellus / Reitt."

Diagnosis. Length 2.8–2.9 mm; elytra regularly narrowing towards apex; external face of protibiae without tubercles, with setae directly inserted in tegument; antennomeres VIII–XI longer than wide; parameres very robust, slightly longer than apex of median lobe, with rounded apex ( Fig. 18 ); apex of median lobe regularly arched ( Fig. 11 ). Molecular data place S. pulchellus as sister species of S. vandalitiae .

Remarks. Speonemadus pulchellus was considered to be a subspecies of S. orchesioides by Jeannel (1936: 214), and a synonym by Giachino & Vailati (1993). All the studied and figured specimens of Speonemadus from Sicily (see Appendix) share a more or less similar aedeagus, which is also similar to that of the specimen from Djebel Babor figured by Giachino & Vailati (1993) as S. orchesioides , and that we consider to belong to S. pulchellus . There are some small differences in the apex of the aedeagus of the specimens from Ficuzza (Appendix), which are slightly more rounded than those of the lectotype. We consider these differences as intraspecific variation, although the study of additional material may prove the existence of consistent variation deserving taxonomic recognition. In any case, the aedeagi of the material considered under the name S. pulchellus are clearly different to that of the male identified as S. orchesioides by us (from Ammi-Moussa, see above) ( Figs 5 , 13 and 11 , 18 respectively).

Distribution ( Fig. 38 ; Appendix): Italy (including Sicily), Eastern Algeria and likely Tunisia.
