description: Agrilus wos sp. nov.
(Figs. 1D, 5D)
Description of holotype. Body length: 5.7 mm. BODY. Shape: subparallel, Profile: convex, Color (dorsally): unicolored. HEAD. Modification: strongly convex. Vertex. Medial impression: present, Sculpture elements: rugae, Sculpture aspect: arcuate. Eyes. Size: subequal or larger 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 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: projecting beyond anterior angles. Posterior angles. Shape: acute, Apex: sharp. Disk. Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): shallow. Prehumerus. Development: obsolete, Shape: arcuate, Extent: adjoining posterior angle, Anterior end: distant from lateral pronotal carina, Posterior end: joined with posterior pronotal angle or margin. Lateral carinae. Convergence: moderate, Junction: present, 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. Pubescence. Extent: proximal and distal, Proximal (shape): quadrangular, Distal (shape): apical. STERNUM. Pubescence. Strip of erect pubescence: extending from prosternal lobe to metasternal projection. Prosternal lobe. Size: large, Position to sternum: markedly declivous, Distal margin: arcuately emarginate, Emargination (depth): shallow, Emargination (width): wide. Prosternal process. Width: wide, Shape: markedly dilated, Angles: obtuse, Angles (tips): blunt, Disc: flat, Projection (length): protruding distinctly beyond angles. Metasternum. Metasternal projection: flat. ABDOMEN. Basal ventrite. Modifications: absent. Pygidium. Apical margin: arcuate. Sternal groove. Shape on apex of last ventrite: arcuately sinuate. LEGS. Metatarsus. Length to metatibia: somewhat shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4, Modification: with comb of setae on lower side. GENITALIA. Aedeagus. Symmetry: symmetric, Modifications: apex of medial lobe markedly obtuse, medial lobe distinctly wider than parameres.
Variability. Body length: 5.1–5.7 mm. The paratype has broadly, separately arcuate elytral apices. Sexual dimorphism. The male has a strip of erect pubescence on the sternum and a comb of erect setae on the first metatarsomere. The female is unknown. Diagnosis. Agrilus wos sp. nov. is similar to A. volkovitshi Jendek, 2007 by the color, by the habitus, by the size of the eyes, by the shape of the pronotum, and by the pattern of the elytral pubescence. The new species can be distinguished by the obliterate prehumerus, by the shape of aedeagus (Fig. 5D), by the lack of tubercles on the basal ventrite, and by the presence of long setae on the first metatarsomere in the males.
