Other material: male, PERU: ‘Gb Madre de Dios 500m’ ( MNHN).

Diagnosis. Elytra with 4 costae, costa 3 present only in median third. Pronotum only slightly widened distally. Antennomere 3 as long as 4, antennomeres with lateral margins rounded. Phallus broad, weakly narrower than parameral width, paramerae slightly shorter than half of phallus.

Redescription. Interocular distance 1.5 times longer than eye diameter. Antennomere 3 as long as half of 4 ( Fig. 13 ). Mandibles reduced, maxillary palpi elongate, tips slightly truncate. Pronotum trapezoidal, slightly widened distally, provided with simple median longitudinal carina ( Fig. 1 ), lateral margins yellow.
