Description of holotype. Body length: 4.3 mm. BODY. Shape: subparallel, Build: robust, Posterior tapering part: short with broad apex, Color (dorsally): unicolored. HEAD. Size: very large, Modification: obviously flat. Vertex. Outline: markedly protruding head outline, Medial impression: present, Sculpture elements: rugae, Sculpture density: sparse, Sculpture intensity: superficial. Eyes. Size: smaller than half width of vertex (dorsal view), 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 middle, Anterior margin: subequal to posterior. Anterior lobe. Development: absent or vague. Posterior angles. Shape: rectangular, Apex: sharp. Disk. Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): deep. Prehumerus. Development: carinal, Shape: bisinuate, Extent: to anterior angle, Anterior end: joined with anterior pronotal angle, Posterior end: joined with posterior pronotal angle or margin, Arc: weak. Lateral carinae. Interspace: narrow, Convergence: moderate, Junction: present, Narrowest point: at posterior 1/3 of marginal carina. ELYTRA. Color: unicolored, Humeral carina: absent. Apices. Arrangement: separate, Shape: arcuate. Pubescence. Extent: entire ornamental with indication of stripes. STERNUM. Prosternal lobe. Size: large, Distal margin: arcuate. Prosternal process. Shape: slightly dilated, Sides: straight, 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: distinctly shorter. Metatarsomere 1. Length to following tarsomeres: subequal or longer than 2–4. GENITALIA. Ovipositor. Shape: markedly elongate.
Variability. The species is known only from the female holotype.
Diagnosis. Agrilus titi sp. nov. is similar to A. evolutus Descarpentries & Villiers, 1963 by the size, by the color, by the habitus, by the very small eyes, by the markedly transverse pronotum, and by the similar elytral pubescence. The new species can be distinguished by the sinuate carinal prehumerus extending to the anterior pronotal angles.
Type material. Type locality: Malaysia, West Perak, 25 km Northeast of Ipoh, Banjaran Titi Wangsa mts., Korbu Mt., altitude 1200 m. Type specimens. Holotype (EJCB): “ Malaysia, W Perak, 25 km NE of Ipoh, 1200 m, Banjaran Titi Wangsa mts., Korbu Mt., 6–12.v.2001, P. Čechovský leg.”.
Distribution. MALAYSIA: Perak.
Etymology. The specific name is derived from a part of the name of the Banjaran Titi Wangsa Mountains, the type locality.
