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.
