Remarks. The lectotype of Sciaphilus submaculatus is 4.88 mm long. The lectotype of Sciaphilus alboscutellaris is 5.94 mm long. With a moderately large, densely squamose body with elongate-oval elytra C. submaculatus somewhat resembles Sciaphilus asperatus (Bonsdorff, 1785) . From all other Chiloneus species it is distinguishable by its raised elytral setae very short, at apical declivity shorter than half the width of one elytral interval, scutellum densely covered by whitish appressed scales and large, angular, subtrapezoidal frontoepistomal area.
