SEM pictures of Meligethes (s.l.) spp.; a left eye and ventral portion of temples (Meligethes flavimanus); b left eye and lateral portion of temples (Odonthogethes castanescens). Arrows indicate shared pit in ventral subocular lateral portions of temples (inside terminal posterior portion of ventral furrows in members of subgenus Meligethes s. str., laterad and more dorsad in members of Odonthogethes). c Microsetae along posterior edge of pronotum of Odonthogethes castanescens. d Left portion of last visible abdominal ventrite of Odonthogethes denticulatus. e Right maxillary palp and labial palp of Odonthogethes denticulatus. f Prosternum, prosternal process and mesoventrite of Odonthogethes denticulatus. g Left protibia, dorsal view, of Meligethes atratus. h Close-up of left protibia, dorsal view, of Odonthogethes castanescens, with pre-distal tooth and spicule. Dorsal head view in Meligethinae; i Meligethes atratus; j Brassicogethes aeneus. Arrows of Figs (i) and (j) point to the shared absence of dorsal circumocular furrows on dorsal head surface.
