description: Agrilus aruensis sp. nov.
(Figs. 1A, 5A)
Description of holotype. Size: 4.1 mm. Body. Shape: cuneiform; Build: robust; Posterior tapering part: short with broad apex; Profile: convex; Color (dorsally): bicolored. Head. Size: very large; Modification: strongly convex; Medial impression: shallow; Epistoma: in plane with frons. Frons: Shape: flat. Vertex: Sculpture elements: rugae; Sculpture aspect: arcuate. 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: sinuate before posterior angles, slightly arcuate; Maximal width: at middle; Anterior margin: subequal to posterior. Anterior lobe: Development: moderate; Shape: arcuate; Width: broad; Position: projecting beyond anterior angles. Posterior angles: Shape: acute. Disk: Convexity: strongly convex; Impressions: medial only; Medial impression: entire. Prehumerus: Development: carinal; Shape: arcuate; Extent: adjoining posterior angle, to 1/3 of pronotal length; Anterior end: distant from lateral carina; Arc: moderate. Lateral carinae: Convergence: moderate; Junction: absent; Narrowest point: at posterior angles. Scutellum: Size: robust. Elytra. Color: bicolored; Alternative color: apical portion; Humeral carina: absent. Apices: Arrangement: conjoint; Shape: arcuate. Pubescence: Color: unicolored; Extent: proximal and distal; Proximal (shape): like V, X, Y, T; Distal (shape): preapical. Sternum. Pubescence: Strip of erect pubescence: extending from prosternal lobe to abdominal intercoxal projection. Prosternal lobe: Size: large; Distal margin: arcuately emarginate; Emargination (depth): shallow. Prosternal process: Width: wide; Shape: slightly dilated; Sides: arcuate; Angles: obtuse; Angles (tips): sharp; Disc: impressed; Projection (length): protruding distinctly beyond angles. Metasternum: Metasternal projection: flat. Abdomen. Sternal groove: Extent: on two apical ventrites; 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. 5A): Shape: widest in basal part; Profile: convex.
Variability. Unknown. Sexual dimorphism. The male has strip of long, erect, white pubescence on ventral side extending from prosternal lobe to abdominal intercoxal projection. The female is unknown.
Diagnosis. Agrilus aruensis sp. nov., A. chloros sp. nov. and A. bicoloripennis sp. nov. are species with bright golden–green or golden–blue color. Agrilus aruensis sp. nov. has elytra bicolored similarly like A. bicoloripennis sp. nov., but it differs from it by having elytral apex much broader; by distal part of elytral pubescence limited to perisutural area, by strip of long pubescence on ventral side (see sexual dimorphism) and by shape of aedeagus (Fig. 5A).
Type material. Type locality: Indonesia, Maluku, Aru Island [06°12'04”S, 134°28'58”E]. Type specimens. Holotype ♂ (FWPC): “Aru”.
Distribution. Indonesia (Maluku Islands, Aru Island).
Etymology. The specific name refers to the type locality.
Remarks. Known only from the holotype.
