Description of holotype. Length 6.8 mm. Dorsal color black with dark green reflection at base of elytra. Pair (1+1) of spots of pruinose pubescence at ¾ length of elytra from which begins a stripe of pubescence less pruinose, that follows suture to apex. Vertex width of half of anterior margin of pronotum. Frons furrowed, with pubescent spot at base. Clypeus small, separated from frons by a transverse carina. Antennae short, serrate from antennomere 4. Eyes large, with genae small, black and glabrous. Pronotum wider anteriorly, with lateral margins slightly arcuate and posterior angles obtuse. Disc irregular, with two central depressions located after vertex and before scutellum. Sculpture composed of transversal striae. A stripe of white pruinose pubescence covers integuments along lateral sides, more visible in anterior angles. Premarginal carinula strong, not entire, as long as 1/3 the length of marginal carina. Submarginal and marginal carinae convergent, joined at base. Scutellum black, transversely carinate. Elytra with apex rounded and microdenticulate. Sterna black, with yellowish-white pubescent spot at lateral sides of each sternite. Same pubescence also at metepisternum and metecoxa. Legs black, all claws mucronate. Metatarsus shorter than metatibia, with the first article shorter than the sum of the following three (1<2+3+4). Aedeagus fusiform, with median lobe pointed (figure 12).

Description of paratypes. Length 8.6 and 8.8 mm. Large sexual dimorphism: females with head and pronotum gold and elytra with 8 (4+4) small, round pale yellow spots of pruinose pubescence: first pair in humeral callus; second at 1/3 the length of elytra, near suture; third at half, near lateral margins; fourth at 2/3 the length, near suture. From this last pair of spots a stripe of pubescence less pruinose begins, as in male ( Figure 3 ).

Etymology. This new species name honors one of the collectors, Heinz Dauber.

Comments. Sexual dimorphism together with the pattern of elytral pubescent spots makes this species unmistakable from other Central America congeners.
