Body surface bare, dull ( Fig. 3 A). Head with dense punctures, 1–2 diameters apart. Clypeus scarcely emarginated. Mentum widest at middle; narrowing towards apex. Submentum triangular. Prosternite medially covered with long but sparse setae. Hypomeron glabrous and impunctate. Pronotum covered with fine punctures, 1–3 diameters apart; anterior and basal borders complete; lateral border not widened basally, narrow (width 2x greater than width of submarginal depression); lateral margins actuate from anterior to posterior ends. Intercoxal process of prosternum angular in lateral view. Scutellum triangular, with fine punctures. Elytral striae punctatesulcate; punctures fine, 4–5 diameters apart. Intervals dull; with visible microsculpture (magnification 50x); punctures scarcely visible, 3–4 diameters apart. Elytral humeri protruding laterally. 5th abdominal ventrite without submarginal sulcus; with irregularly distributed punctures, 1–2 diameters apart. Pro- and mesotarsi in both sexes not widened. Female protibiae evenly widened towards apex. Male protibiae with preapical concavity on inner side. Inner face of male metafemora with longitudinal concavities ending with large denticles. Female metafemora simple. Other leg segments without modifications.

Parameres evenly narrowing towards apex; not fused basally. Ovipositor with coxites subequal in length to paraproct. Valvifers short and wide, other lobes elongate. Gonostyli situated on dorsal part of apical lobe of coxities.

Etymology. I have named this species in honor of my friend Kojun Kanda, specialist in Tenebrionidae , to whom I am greatly indebted for his help during my Pedinini project.

Distribution. This species has been collected in the eastern part of the Baviaanskloof Nature Reserve, near the Komdomo campsite (GPS coordinates: -33.739, 24.614) ( Fig 1 ).
