Description of holotype. Body length: 5.7 mm. BODY. Shape: subparallel, Profile: convex. HEAD. Vertex. Medial impression: present, Sculpture elements: rugae, Sculpture aspect: subparallel, Sculpture density: dense.
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, Antennomeres 7–10: with obvious petiole. PRONOTUM. Shape: visually transverse, Sides: slightly arcuate, Maximal width: at middle, Anterior margin: narrower than posterior. Anterior lobe. Development: obvious, Shape: arcuate, Width: broad, Position: at level with anterior angles. Posterior angles. Shape: rectangular, Apex: blunt. Disk. Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): shallow, Lateral impressions (width): broad. Prehumerus. Development: carinal, 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 1/5–1/4 of marginal carina. ELYTRA. Color: unicolored, Humeral carina: absent.
Apices. Arrangement: separate, Shape: arcuate. Pubescence. Presence: without discernible pubescence. STERNUM. Pubescence. Strip of erect pubescence: absent. Prosternal lobe. Size: large, Position to sternum: markedly declivous, Distal margin: arcuately emarginate, Emargination (depth): shallow, Emargination (width): wide. Prosternal process. Shape: markedly dilated, Sides: straight, Angles: obtuse, Angles (tips): blunt, Disc: flat with cluster of setae, Projection (length): protruding distinctly beyond angles. Metasternum. Metasternal projection: impressed. ABDOMEN. Basal ventrite. Modifications: absent. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuately sinuate, Sinuosity (depth): markedly deep, Sinuosity (width): very narrow. LEGS. Metacoxal plates. Modifications: with tubercle on inner margin. Metatarsus. Length to metatibia: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: longer than 2–3 but shorter than 2–4. GENITALIA. Aedeagus. Symmetry: feebly asymmetric, Profile: flat.
Variability. The species is known only from the male holotype.
Diagnosis. Agrilus uxo sp. nov. is similar to the Palaearctic A. graminis Kiesenwetter, 1857 by the habitus and by the presence of a cluster of setae on the base of the prosternal process. The new species can be distinguished by unmodified antennae in males, by the lack of white elytral pubescence, by a small cluster of setae on the inner margin of the metacoxae, and by the shape of the aedeagus ( Fig. 5E View FIGURES 5 ).
Type material. Type locality: North Vietnam, Ninh Binh province, Cuc Phuong National Park, N 20°21'10”, E105°35'00”, altitude 440 m. Type specimens. Holotype ♂ ( EJCB): “N Vietnam, Ninh Binh prov., Cuc Phuong N. Park, N20°21'10”, E105°35'00”, 24–28.iv.2012, alt 440m, E. Jendek leg.”.
Distribution. VIETNAM: Ninh Binh.
