Vertex Medial impression: present, Sculpture elements: rugae, Sculpture aspect: arcuate. Eyes Size: subequal or larger than width of vertex (dorsal view), Lower margin: in line or below antennal socket, Median orbit: converging ventrally. Antennae Serration: from antennomere 4. PRONOTUM. Shape: visually transverse, Sides: slightly arcuate, Maximal width: at posterior margin, Anterior margin: narrower than posterior. Anterior lobe Development: obvious, Shape: arcuate, Position: projecting beyond anterior angles. Posterior angles Shape: rectangular, Apex: sharp. Disk Impressions: medial and lateral, Medial impression: entire, Lateral impressions (depth): deep. Prehumerus Development: carinal, Shape: arcuate, Extent: to 1/3 of pronotal length, Anterior end: distant from lateral carina, Posterior end: joined with posterior angle or margin, Arc: weak. Lateral carinae Interspace: narrow, Convergence: moderate, Junction: present, Narrowest point: at posterior angles. ELYTRA. Color: unicolored, Humeral carina: absent. Apices Arrangement: separate, Shape: arcuate, Modifications: margin obviously denticulate. Tomentum Pairs of tomentose spots: humeral, medial, apical. Pubescence Color: unicolored. STERNUM. Pubescence Strip of erect pubescence: absent. Prosternal lobe Size: large, Distal margin: subtruncate. Prosternal process Width: wide, Shape: subparallel, Sides: arcuate, Angles: obtuse, Angles (tips): blunt, Disc: flat, Projection (length): protruding distinctly beyond angles, Metasternum Metasternal projection: flat. ABDOMEN. Basal ventrite Modifications: without modifications. Pygidium Apical margin: arcuate. Sternal groove Extent: on all ventrites, Shape on apex of last ventrite: arcuate. LEGS. Metatarsus Length to metatibia: distinctly shorter. Metatarsomere 1 Length to following tarsomeres: longer than 2–3 but shorter than 2–4. GENITALIA. Aedeagus Symmetry: symmetric, Shape: subparallel.

Variability. Known only from the single male. Aedeagus (Fig. 3C).

Diagnosis. By slender body and arcuate pronotal sides, A. oudomxai sp. nov. is very similar to A. pluridens . It differs in having eye in male subequal to width of vertex (dorsal view) and elytral apices only finely denticulate.
