( Fig. 1BView FIGURE 1)

Description of holotype. Size: 3.9 mm. Body. Shape: cuneiform; Build: robust; Profile: convex; Color (dorsally): unicolored. Head. Size: very large; Medial impression: shallow. Frons: Outline: markedly protruding head outline. Vertex: Outline: markedly protruding head outline; Sculpture elements: rugae; Sculpture aspect: arcuate; Sculpture density: dense; Sculpture intensity: superficial. Eyes: Size: subequal to half width of vertex (dorsal view); Lower margin: in line or below antennal socket; Median orbit: converging ventrally. Antennae: Serration: from antennomere 4. Pronotum. Shape: visually transverse; Sides: sinuate before posterior angles, straight; Maximal width: at posterior margin; Anterior margin: narrower than posterior. Anterior lobe: Development: obvious; Shape: arcuate; Width: broad; Position: at level with anterior angles. Posterior angles: Shape: acute; Apex: sharp. Disk: Convexity: strongly convex; Impressions: lateral only; Lateral impressions (depth): shallow; Lateral impression (width): broad. Prehumerus: Development: carinal; Shape: arcuate; Extent: beyond 1/2 of pronotal length; Anterior end: distant from lateral carina; Posterior end: joined with posterior angle or margin; Arc: moderate. Lateral carinae: Convergence: moderate; Junction: present; Narrowest point: at posterior 1/5–1/4 of marginal carina. Scutellum: Size: robust. Elytra. Color: unicolored; Humeral carina: absent. Apices: Arrangement: conjoint; Shape: arcuate. Pubescence: Color: unicolored; Extent: proximal and distal; Proximal (shape): quadrangular; Distal (shape): preapical. Sternum. Prosternal lobe: Distal margin: arcuately emarginate; Emargination (width): wide. Prosternal process: Shape: subparallel; Sides: straight; Angles: obtuse; Angles (tips): blunt; Disc: flat; Projection (length): protruding distinctly beyond angles. Metasternum: Metasternal projection: flat. Abdomen. Basal ventrite: Modifications: with transverse protrusion. Pygidium: Apical margin: arcuate. Sternal groove: Extent: on apical ventrite; Shape on apex of last ventrite: arcuately sinuate; Sinuosity (delimitation): angulate; Sinuosity (depth): markedly deep; Sinuosity (width): markedly wide. Legs. Metatarsus: Length to metatibia: distinctly shorter. Tarsomere 1: Length to following tarsomeres: shorter or subequal to 2–3.

Variability. Unknown. Sexual dimorphism. The male has obvious transverse protrusion on basal ventrite, similarly like A. incrassatus  sp. nov. and A. traymanyi  ( Tab. 1). The female is unknown.

Diagnosis. Agrilus ateles  sp. nov. differs from similar species by obviously transverse pronotum with maximal width at posterior margin and by lacking cluster of long setae on apex of metatibiae.

Type material. Type locality: Malaysia, Sabah, Mt. Kinabalu NP [06°08'00”N, 116°39'00”E]GoogleMaps  . Type specimens. Holotype ♂ ( FWPC): “ Malaysia, Sabah, Mt. Kinabalu NP, 6,7. ix.1990, CL Bellamy ”. 

Distribution. Malaysia (Sabah).

Etymology. The specific name is derived from the Greek ateles  (incomplete or imperfect development). It refers to the lack of aedeagus of the holotype.

Remarks. Known only from the holotype. The aedeagus of holotype was lost most probably when the specimen was mounted.
