( Figs. 2D, 2L )

Description of holotype. Length: 10.5 mm. BODY. Shape: cuneiform; Color (dorsally): unicolored. HEAD. Medial impression: deep. Vertex. Sculpture elements: rugae; Sculpture aspect: arcuate; Sculpture density: dense; Sculpture intensity: rough. Eyes. Size: subequal or larger than width of vertex (dorsal view); Shape: markedly protruding head outline; Lower margin: in line or below antennal socket; Median orbit: converging ventrally.

Antennae. Serration: from antennomere 4. PRONOTUM. Shape: visually transverse; Sides: markedly arcuate; Maximal width: at posterior margin; Anterior margin: narrower than posterior. Anterior lobe. Development: absent or vague; Position: not reaching level of anterior angles. Posterior angles. Shape: obtuse; Apex: sharp.

Disk. Impressions: medial and lateral; Medial impression: posteromedial only; Lateral impressions (depth): deep; Lateral impressions (width): broad. Prehumerus. Development: carinal; Shape: bisinuate; Extent: beyond 1/2 of pronotal length; Anterior end: joined with lateral pronotal carina; Posterior end: distant from posterior pronotal angle or margin; Arc: obvious. Lateral carinae. Interspace: narrow; Convergence: moderate; Junction: present; Narrowest point: at posterior 1/5–1/4 of marginal carina; Modifications: submarginal carina anteriorly obliterate.

Scutellum. Disc: impressed. ELYTRA. Humeral carina: absent. Apices. Arrangement: separate; Shape: cuspidate; Number of cusps or spines: 1; Position of dominant projection: pleural margin. Pubescence. Presence: without discernible pubescence. STERNUM. Prosternal lobe. Size: large; Distal margin: arcuate. Prosternal process. Width: wide; Shape: slightly dilated; Sides: arcuate; Angles: rectangular; Angles (tips): blunt; Disc: flat; Projection (length): protruding distinctly beyond angles. Metasternum. Metasternal projection: flat. ABDOMEN. Tomentum: present. Basal ventrite. Modifications: absent. Pygidium. Apical margin: with spine. Last ventrite. Shape: with narrow apex. Sternal groove. Shape on apex of last ventrite: arcuate. LEGS. Metatarsus. Length to mesotarsus: obviously longer; Length to metatibia: somewhat shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA. Aedeagus. Symmetry: symmetric; Shape: subparallel.

Variability. Body length: 9–12.2 mm. Without discernible variability except for the size. Sexual dimorphism. The prosternal process in male with denser but very short pubescence. The female has ovipositor markedly elongate.

Type material. Type locality: Indonesia , Maluku, Ambon Island. Type specimens. Holotype ♂, 7 PT ( EJCB): “Indonesia, Ambon Island, iv-v.2009, local collector”. Other paratypes. INDONESIA. Maluku. “Indonesia, Ambon Island, x.2009, local collector” 1 ♂ PT ( EJCB) \\ “Indonesia, Seram Island, Manusella, 2.2010, local collector lgt.” 2 ♀ PT ( EJCB) \\ “Indonesia, Ambon Island, iii.2 0 12, local collector” 2 ♂ PT ( EJCB).
