Scapus longer than 1st segment. 2nd segment elongated, shorter than 1st segment. 3rd-4th segments weaker elongated, shorter than 2nd segment. 5th-6th segments elongated trapezoid, shorter than 4th segment. 7th segments trapezoid, wider and shorter than 6th segment. Clava weak widened, much shorter than funicle. 1st segment almost conic. 2nd segment trapezoid, shorter and narrower than 1st segment. 3rd segment tear-shaped, longer than 2nd segment, weakly pointed. Pronotum almost rectangular, 1.17 as wide as long, weakly narrowed to the basis and apex, lustrous, densely and small punctate. Greatest width on the middle. Sides almost direct. Scutellum almost rectangular, small. Elytra elongated, 1.47 times as long as wide. Humeri weakly convex. Greatest width on the middle. Intervals wide, flat, lustrous, smooth.

Femora weakly widened. Protibiae almost straight, weakly widened to apex, with 2 spurs at apex. Meso - and metatibiae shorter, weakly curved, with spurs at apex. Tarsi long. 1st segment elongated triangular, longer than 2nd segment. 2nd segment triangular, not projecting over base of 3rd segment. 3rd segment bilobed. Clausal segment elongated. Claws with rounded swelling at base. Length of body: 3.0 mm.

Diagnosis. This new species is very similar to Atopomacer ites Kuschel, 1989 from USA but can be distinguished by the more strongly convex eyes, narrower rostrum, smaller sizes of the body (3.0 mm), narrower pronotum, aedeagus narrowed to apex and sclerotized endophallus.

Etymology. The name is formed from the name “ Honduras ” – “hondurasensis ”.

Distribution. Honduras.
