Diagnosis

This species can be distinguished from other Tiniocellus species by the following combination of characters (Fig. 2 d): Length 6.5 mm, breadth 3 mm; upper surface dark brown; head short and broad, both coarsely and finely punctured with the large punctures setiferous, with the genae protruding from sides of clypeus at clypeo-genal junction and the vertex bears two sinuate carina basally; clypeus rugosely punctured, anteriorly reflexed and feebly excised in the middle; pronotum coarsely and closely punctured, disc without testaceous patches and bears a shallow median basal furrow occupying approximately half of its length; elytra not completely covering the abdomen and met-episterna at the sides, shallowly striate, interstriae flat, wide and fringed before the hind margin, 1st interstria with four and 5th with three long erect setae, 3rd and 7th without long erect setae other than the tuft on apical declivity; metasternal shield smooth, with a spoon shaped concavity at the end of impunctate and shining mid-line; pygidium wider at base than the 1st to 5th elytral interstriae of the two elytra taken together; hind femur devoid of setae on postero-inferior edge.
