Chiloneus chobauti View in CoL (Desbrochers des Loges, 1897)

Sciaphilus chobauti Desbrochers des Loges, 1897: 11.

Sciaphilus inhumeralis Pic, 1903: 124 View in CoL , syn. nov. Type locality: Algérie, Biskra. Chiloneus inhumeralis: Dalla Torre et al., 1937: 177 View in CoL ; Borovec, 2013b: 379. Chiloneus chobauti: Winkler, 1932: 1469 View in CoL ; Dalla Torre et al., 1937: 176; Borovec, 2013b: 379.

Type locality. Algérie, Ghardaia (Desbrochers des Loges, 1897).

Type material examined. Sciaphilus chobauti . Lectotype (here designated): 1 spec. ( MNHN, Desbrochers coll.), ‘Ghardaia [hw] // chobauti / m. [hw] // Ex Museo / Desbrochers / 1914 [p] // LECTOTYPUS / Sciaphilus / chobauti Desbr., 1897 / Borovec & Perrin desig. 2015 [p, red] // Chiloneus / chobauti (Desbr) , R. Borovec det. 2015 [p]’.

Sciaphilus inhumeralis . Lectotype (here designated): 1 spec. ( MNHN, Pic coll.), ‘ Algérie / Biskra [hw] // 20 [hw] // sp.? / (Dsbr. vid) [hw] // type [hw, yellow] // Sc. inhumeralis / Pic [hw] // TYPE [p, red] // LECTOTYPUS / Sciaphilus / inhumeralis Pic, 1903 / Borovec & Perrin desig. 2015 [p, red] // Chiloneus chobauti (Dsbr.) / R. Borovec det. 2015 [p]’.

Additional material examined. 1 spec., Morocco bor. or., Bir Taddart ( MNHN, Peyerimhoff coll.); 3 spec., Tunisia mer., Ben Cheradin ( MNHN, Peyerimhoff coll.).

Remarks. The lectotype of Sciaphilus chobauti is 4.91 mm long. The lectotype of Sciaphilus inhumeralis is 4.52 mm long. Both specimens are conspecific, the latter only slightly more slender (most likely male), thus Sciaphilus inhumeralis is a subjective junior synonym of Sciaphilus chobauti . This species is distinguishable from all other Chiloneus species by the conspicuous, large, regularly flat, smooth and shiny semicircular frontoepistomal area, contrasting with the densely squamose rostrum and dense, moderately long semierect elytral setae, creating two rows on each interval.
