Supraorbital setae located at mid-eye and gena level. Neck composed of a transverse conspicuously raised slightly convex costa, slightly adjoining other costae at extremities. Surface of head covered with distinct isodiametric reticulation, fields of meshes distinctly convex. Eyes subglobose, not as high as supraantennal plates. Genae indistinct.

22 Antenna subelongate, reaching distinctly over posterior setigerous puncture of pronotum, segments five to ten distinctly longer than wide. Labrum slightly excised, with transverse reticulation, seven-setose. Mandible moderately long, straight at middle part, acute and arcuate nearly hook-like at apex, reflexed margined. Apical segment of maxillary palpomere elongate, securiform, pointed at apex, terminal segment of labial palpomere bottle like, slender apically. Mentum with lateral lobes bidentate, lateral teeth acute, projecting anteriorly, moderately excised between teeth, surface with irregular rugae, central tooth between lobes not as projecting as lateral teeth.

Pronotum ( Figs 8 , 15): Planate to slightly convex on anterior half of disc (lateral view). Distinctly convex in frontal view. Outline square, wider than long. Lateral margin straight in anterior half, converging, contracted to anterior angle. Anterior angle rounded off by reflexed lateral margin. Reflexed lateral margin subcrenulated. Lateral channel moderately narrow, as wide as two times the width of reflexed lateral margin. Anterior setigerous puncture situated in marginal channel, posterior puncture removed from channel by two times the diameter of puncture. Posterior angle marked by a small tooth. Pleura visible in dorsal view. Anterior margin slightly excised. Anterior transverse line wide, not reaching anterior angles, with conspicuous transverse carina between anterior margin and anterior transverse line, distinctly interrupted at middle. Median line wide, valley-like, joining with anterior transverse line and basal constriction, bilaterally with distinct carina in anterior two thirds. Basal constriction of moderate size, flange with sharp carina. Disc shiny, with small but deep wrinkles of coreaceate-like structure, fields between wrinkles distinctly convex, lines of meshes more transverse towards base, fields between meshes convex.

Elytra ( Fig. 8 ): Slightly transversally depressed in anterior third (lateral view). Elongate, sides nearly straight at middle, maximum width at middle. Base truncated nearly straight. Marginal channel moderately wide, running over rounded humerus up to level of fifth stria, series of umbilical setigerous punctures not interrupted. Reflexed margin smooth. Humeral tooth distinct. Striole distinct, elongated. Basal tubercle with setigerous puncture distinct, situated at declivity of first stria, tubercle at declivity of interval three distinct. Striae one to four free at base, all striae deep, indistinctly punctuate-striate. Intervals distinctly convex, carinate apically. Interval three with four setigerous punctures, all approaching stria three. Surface of intervals shiny.

Hind wings: Fully developed.

Ventral description: Proepisternum with dense transverse wrinkles, pleura somewhat swollen postero-laterally. Prosternum smooth, glossy. Abdomen smooth, shiny, laterally with isodiametric reticulation. Last five abdominal sternites with two rows of setae. Abdominal sternum with the two bigger marginal setae separated.

Legs: Profemur dorsally covered densely with transverse parallel wrinkles and irregular reticulation, ventrally with nine transverse carinae. Protibia with the three upper spines elongated, the basal one shorter and rounded off, surface with longitudinal reticulation, movable apical spur distinctly shorter than terminal spine, spur and spines rounded apically, basal tarsomere nearly as long as tarsomeres two to five together. Mesotibia without preapical spine, with four strong setae distally arising from tubercles.

Male genitalia (Fig. 21): Median lobe slender, elongated, in dorsal view distinctly but obtusely angled arcuate at middle, apical part elongated, tip of apex shaped like half of a spoon, with smooth margin. Oroficium of moderate size. Internal sac with a bunch of dense bristles preapically. Parameres medium sized, not much distorted, ventral one with two and dorsal one with three long setae at apex.

Female genitalia (Fig. 27): Coxostyli hyaline, slender, flattened, bottle-like shaped in apical half, with stepped tip of apex, with two moderately long nematiform setae in the middle part and one elongated nematiform setae towards apex, with one minute pilus at tip of apex.

Variation: The hind body of the paratype (female) is slightly more slender. The dark macula at base of the elytra is more distinct in the paratype.

DISTRIBUTION: Found at the beach of Soalala which is located in the North-East of Madagascar.
