Surface sculpture: Punctation and microreticulation as in Exocelina irianensis sp. n. Structures: Pronotum without lateral bead, in a very few specimens with indistinct traces of bead. Base of prosternum and neck of prosternal process with distinct ridge, without anterolateral extensions. Blade of prosternal process lanceolate, relatively broad, slightly convex, with distinct bead and few setae; neck and blade of prosternal process evenly jointed. Abdominal sternite 7 broadly rounded apically. Male: Antennomeres 3–10 stout (Fig. 17A). Protarsomere 4 with middle-sized, slender, evidently curved anterolateral hook. Protarsomere 5 ventrally with anterior row of 14 short setae and posterior row of 5 short setae (Fig. 17B). Abdominal sternite 7 with 3–8 lateral striae on each side. Median lobe slender, with very weak submedian constriction in ventral view (Fig. 17C).
