description: Agrilus zao sp. nov.
(Figs. 1C, 5C)
Description of holotype. Body length: 6 mm. BODY. Shape: subparallel, Profile: convex, Color (dorsally): unicolored. HEAD. Medial impression: absent. Frons. Shape: flat. Vertex. Medial impression: absent, 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. Length: reach to anterior pronotal angles, Serration: from antennomere 4. PRONOTUM. Shape: visually elongate or square, Sides: slightly arcuate, Sides (modification): sinuate before posterior angles, Maximal width: at middle, Anterior margin: subequal to posterior. Anterior lobe. Development: obvious, Shape: arcuate, Width: broad, Position: not reaching level of anterior angles. Posterior angles. Shape: acute, Apex: obtuse. Disk. Impressions: medial and lateral, Medial impression: anteromedial and posteromedial, Lateral impressions (depth): shallow. Prehumerus. Development: carinal, Shape: bisinuate, Extent: beyond 1/2 of pronotal length, Anterior end: adjoining to lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin, Arc: obvious. Lateral carinae. Convergence: moderate, Junction: present, Narrowest point: at posterior 1/5–1/4 of marginal carina. ELYTRA. Color: unicolored, Humeral carina: absent. Apices. Arrangement: separate, Shape: subangulate. Pubescence. Extent: proximal and distal, Proximal (shape): like upturned T, Distal (shape): apical. STERNUM. Pubescence. Strip of erect pubescence: extending from prosternal lobe to metasternal projection. Prosternal lobe. Size: large, Distal margin: arcuately emarginate, Emargination (depth): shallow, Emargination (width): wide. Prosternal process. Width: wide, Shape: markedly dilated, Angles: acute, Angles (tips): blunt, Disc: flat, Projection (length): adjoining to angles. Metasternum. Metasternal projection: flat. ABDOMEN. Basal ventrite. Modifications: with tubercle(s). 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: subequal or longer than 2–4. GENITALIA. Aedeagus. Symmetry: symmetric, Modifications: medial lobe distinctly wider than parameres.
Variability. Body length: 5.7–7.2 mm. Sexual dimorphism. Males with frons and pronotum greenish; sternum with medial strip of erect pubescence. Female with pronotum brownish red; sternum without strip of erect pubescence and ovipositor elongate.
Diagnosis. The new species is similar to the female lectotype of A. tristis Deyrolle, 1864 described from Singapore. It can be distinguished by having the anterior part of the elytral pubescence in the form of an upturned “T”, by the broad prosternal lobe, and by the obviously dilated, tricuspidate prosternal process.
