Description of holotype. Size: 3.8 mm. Body. Shape: cuneiform; Posterior tapering part: long with narrow apex; Profile: convex; Color (dorsally): unicolored. Head. Size: very large; Modification: strongly convex; Medial impression: absent; Episto ma: raised above frons. Vertex: Sculpture elements: rugae; Sculpture aspect: arcuate; Sculpture density: dense; Sculpture intensity: rough. Eyes: Size: subequal to half width of vertex (dorsal view); Shape: markedly protruding head outline; Lower margin: in line or below antennal socket; Median orbit: subparallel. Antennae: Serration: from antennomere 4. Pronotum. Shape: visually transverse; Sides: markedly arcuate; Maximal width: at middle; Anterior margin: narrower than posterior. Anterior lobe: Development: obvious; Shape: arcuate; Width: broad; Position: projecting beyond anterior angles. Posterior angles: Shape: obtuse; Apex: sharp. Disk: Convexity: strongly convex; Impressions: absent. Prehumerus: Development: filamentary; Extent: adjoining posterior angle. Lateral carinae: Convergence: strong; 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; Character: homogenous; Extent: sutural wedge. Sternum. Prosternal lobe: Distal margin: arcuately emarginate; Emargination (delimitation): angulate; Emargination (depth): deep; Emargination (width): wide. Prosternal process: Shape: slightly dilated; Sides: straight; Angles: obtuse; Angles (tips): sharp; Disc: flat; Projection (length): protruding distinctly beyond angles. Metasternum: Metasternal projection: flat. Abdomen. 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: about as long or longer, distinctly shorter. Tarsomere 1: Length to following tarsomeres: shorter or subequal to 2–3. Genitalia. Aedeagus ( Fig. 5M View FIGURE5 ): Symmetry: symmetric; Shape: widest in apical part.
Variability. Unknown. Sexual dimorphism. The male without apparent sexual adaptations. The female is unknown.
Diagnosis. Agrilus sphenopterus sp. nov. is very similar to A. suturistriatus sp. nov. by general appearance; color, narrow elytral apices and by elytral pubescence in form of sutural wedge. The most reliable character for distinguishing both species is the shape of aedeagus.
Type material. Type locality: Malaysia, Perak, 25 km NE Ipoh, 1200 m, Banjaran Titi Wangsa Mountains, Mount Korbu, [01°40'19”N, 101°17'49”E]. Type specimens. Holotype ♂ ( FWPC): “ Malaysia, Perak prov. , 25 km NE Ipoh, 1200 m, Banjaran Titi Wangsa mts. , Korbu Mt. , 1–2.ii.1999, P. Pacholátko leg.” GoogleMaps .
Distribution. Malaysia (Perak).
Etymology. The specific name is a combination of the Greek adjective sphenoid (wedge shaped) and suffix – ptera derived from pterón (wing). It refers to the markedly cunneate shape of elytra.
