( Figs. 2D View FIGURE 2 , 5J View FIGURE5 )
Description of holotype. Size: 3.8 mm. Body. Shape: cuneiform; Build: robust; Profile: convex; Color (dorsally): bicolored. Head. Size: very large; Medial impression: absent. Frons: Shape: flat. Vertex: Sculpture elements: rugae; Sculpture aspect: arcuate; Sculpture density: dense; Sculpture intensity: rough. Eyes: Size: larger than half width but smaller than 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: lateral only; Lateral impressions (depth): shallow; Lateral impression (width): narrow. Prehumerus: Development: carinal; Shape: arcuate; Extent: to 1/3 of pronotal length; Anterior end: distant from lateral carina; Posterior end: joined with posterior angle or margin; Arc: obvious. Lateral carinae: Interspace: broad; Convergence: strong; Narrowest point: at posterior 1/5–1/4 of marginal carina. Scutellum: Size: robust. Elytra. Color: unicolored; Humeral carina: absent. Apices: Arrangement: conjoint; Shape: subtruncate; Truncation: oblique with projecting sutural angle. Pubescence: Color: unicolored; Extent: proximal and distal; Proximal (shape): like V, X, Y, T; Distal (shape): preapical. Sternum. Prosternal lobe: Size: large; Distal margin: arcuately emarginate; Emargination (depth): deep; 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 tubercle(s). Pygidium: Apical margin: arcuate. Last ventrite: Disk: impressed. 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. Genitalia. Aedeagus ( Fig. 5J View FIGURE5 ): Symmetry: symmetric; Shape: subparallel; Modifications: apex of medial lobe sharply pointed.
Variability. Unknown. Sexual dimorphism. The male has head, pronotum and legs golden–orange; ventro– basal margin of metafemora is armed with comb of longer setae; apex of metatibia has cluster of long setae and last ventrite is deeply impressed. The female is unknown.
Diagnosis. Agrilus oidema sp. nov. differs from the homomorphic A. microtatus by characters given in the key. Aedeagus ( Fig. 5J View FIGURE5 ).
Type material. Type locality: Philippines, Negros Oriental, Negros Island, Cuernos Mountains [09°14'38”N, 123°10'36”E]. Type specimens. Holotype ♂ ( FWPC): “ Cuernos Mts. , Negros, Baker”. GoogleMaps
Distribution. Philippines (Negros Island).
Etymology. The specific name is the Greek noun oidēma from oidein (to swell) in apposition. It refers to expanded metafemora of the species.
Remarks. Known only from the holotype.
