Description of Acanthocinus subgenus Acanthobatesianus subgen. nov.

Elytra smooth with at most very weak costae, legs long and slender, antennae 2– 5 x longer than body (shorter in females), femora slender to slightly swollen, ovipositor very short, antennomeres III–V not fimbriate beneath. Pronotum with only 2 anterior, glabrous tubercles. Prosternal process about half as broad as mesosternal process.

Hind tarsi long and slender (the first segment about 1.5 x longer than segments II and III combined). Male genitalia with very short parameres, not separated along inner margin, tegmen forming a straight line, i.e. not bent in middle, anterior margin of tergite VIII strongly elongated with a pointed (sharp) apex. Sclerites inside internal sac very short and fork-like in shape (but well sclerotized). Last visible abdominal sternite in males deeply notched. Ovipositor and last visible abdominal sternite short in females. Spermatheca very small, with a very short secondary shaft or “proboscis” connected to the head.

Type species: Acanthocinus (Acanthobatesianus) guttatus ( Bates, 1873)

Etymology: The name Acanthobatesianus is a combination of parts of the names Acanthocinus and the auctor Bates.
