Description
BODY. Size: 9.6–10.7 mm (Holotype 10 mm).Shape: subparallel, Build: robust, Posterior tapering part: short with broad apex, Color (dorsally): unicolored, Sexual modifications in male: not apparent. HEAD.Size: very large, Medial impression: deep, Epistoma: raised above frons. Vertex: Shape: markedly convex, Sculpture elements: rugae, Sculpture shape: semispherical, Sculpture density: dense, Sculpture intensity: rough. Eyes: Size: small, Shape: markedly protruding head outline, Lower margin: in line or below with antennal socket, Medial orbit: converging ventrally or subparallel. Antennae: Length: long, Width: slender, Serration: from antennomere 4, Antennomere 7–10 (shape): with obvious collum. PRONOTUM.Shape: transverse, Sides: markedly arcuate or slightly arcuate, Maximal width: at middle, Anterior margin: subequal to posterior. Anterior lobe: Size: mode-rate, Shape: arcuate or subangulate, Position: at level with anterior angles. Posterior angles: Shape: acute or obtuse or rectangular, Apex: blunt or sharp. Disk: Conve-xity: flat, Impressions: medial and lateral, Medial impression: anteromedial and posteromedial, Lateral impressions (intensity): shallow, Lateral impression (size): wide. Prehumerus: Development: filamentary, rarely carinal, Shape: bisinuate, Extent: to 1/3 of pronotal length, rarely to 1/2 of pronotal length, Anterior end: distant from lateral carina, Posterior end: joined with posterior angle or margin, Arc: moderate or obvious. Lateral carinae: Convergence: moderately convergent, Junction: present, Narrowest point: at posterior 1/5-1/4 of marginal carina. ELYTRA.Color: monochromatic, Humeral carina: absent. Apices: Arrangement: separate, Shape: arcuate. Pubescence: Color: monochromatic, Character: homogenous or with patches or spots of denser pubescence, Extent: entire ornamental with indication of fasciae or entire ornamental. Tomentum: Spots (pattern): postmedial only. STERNUM. Prosternal lobe: Size: large, Distal margin: arcuate. Prosternal process: Shape: subparallel, Sides: arcuate, Angles: obtuse, Angles (tips): blunt, Disc: flat. ABDOMEN.Tomentum: absent or present. Pygidium: Apical margin: angulate. Sternal groove: Extent: on three apical ventrites, Shape on the apex of last ventrite: arcuate. LEGS. Metatarsus: Size to metatibia: distinctly shorter than metatibia. Tarsomere 1: Size to following tarsomeres: longer than 2-3 but shorter than 2-4. GENITALIA. Aedeagus (Fig. 39): Symmetry: symmetric, Shape: widest in basal part, rarely subparallel, Modifications: apex of medial lobe sharply pointed. Ovipositor: Shape: square (uritiform).
Diagnosis
From the very close Agrilus tonkineus, it can be distinguished by the flat pronotum; by the bi-sinuate prehumerus and by the presence of transverse tomentose strip at apical third of elytra. See also Appendix.
Type locality
China,Hainan, Baihualing, 19.018, 109.836, altitude 300 m.
Type material
Holotype (Fig. 22), ♂, (EJCB): “China, Hainan, Baihualing, 19.018, 109.836, alt. 300 m, vi. 2008 [p]”. Paratypes: 1 paratype (EJCB), 3 paratypes (IZAS) from the same locality as holotype; 1 paratype (EJCB): “[China] Hainan Qiongzhong Baihuashan Mt, 27.v.1997, P. Y. Yu leg. [transcription from Chinese]”. 1 paratype (USNM), 1 paratype (EJCB): “Taichow, China, 1933”.
Adult occurrence:
5–6 . Altitude range: 300 m.
Host plant
Unknown.
Distribution
CHINA:Hainan; Zhejiang.
Etymology
The specific name is Latin adjective mucidus (moldy). It refers to the elytral tomentum of the species.
