description: Agrilus yoa sp. nov.
(Figs. 3E, 5N)
Description of holotype. Body length: 4.3 mm. BODY. Shape: cuneiform, Build: robust, Profile: convex. HEAD. Medial impression: deep. Frons. Shape: flat. Vertex. Outline: markedly protruding head outline, Sculpture elements: rugae, Sculpture aspect: arcuate, Sculpture density: dense. Eyes. Size: smaller than 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: slightly arcuate, Maximal width: at posterior margin, Anterior margin: narrower than posterior. Anterior lobe. Development: obvious, Width: broad, Position: at level with anterior angles. Posterior angles. Shape: obtuse, Apex: blunt. Disk. Impressions: lateral only, Lateral impressions (depth): shallow, Lateral impressions (width): narrow. Prehumerus. Development: obsolete, Shape: arcuate, Extent: to 1/2 of pronotal length, Anterior end: distant from lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin, Arc: weak. Lateral carinae. Convergence: moderate, Junction: present, Narrowest point: at posterior angles. ELYTRA.
Apices. Arrangement: conjoint, Shape: arcuate. Pubescence. Character: with patches or spots of denser pubescence. STERNUM. Pubescence. Strip of erect pubescence: absent. Prosternal lobe. Distal margin: arcuately emarginate, Emargination (depth): deep. Prosternal process. Shape: subparallel, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: flat. Metasternum. Metasternal projection: impressed. ABDOMEN. Basal ventrite. Modifications: with transverse protrusion. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuately sinuate, Sinuosity (depth): markedly deep. LEGS. Metatarsus. Length to metatibia: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: longer than 2–3, but shorter than 2–4. GENITALIA. Aedeagus. Symmetry: symmetric, Profile: flat.
Variability. Body length: 4.3–5.3 mm. Elytral apices of paratypes are widely, separately arcuate. Sexual dimorphism. The males with frons golden-green. The females with frons golden-red; antennae shorter and ovipositor elongate.
Diagnosis. Agrilus yoa sp. nov. is similar to A. cicadelloides sp. nov. (Fig. 3C) by the size, by the color, by the habitus, and by the shape of the pronotum. The new species can be distinguished by the absence of a cluster of long setae on head, by the less prominent prosternal lobe, and by the different pattern of the elytral pubescence.
