Cycnidolon praecipuum sp. nov.

( Fig. 3 )

Head black. Frons and vertex with silky, white pubescence. Eyes not divided. Antennae (female) almost reaching the apices of the elytra. Scape reddish-brown with blackened tip. Antennomeres III-X black with orange in basal third.

Prothorax black. Pronotum with a gibbosity on each side near the anterior third; pubescence white, sparse, most evident before gibbosities and on sides of the base; remainder of the surface practically glabrous. Lateral parts of prothorax glabrous. Prosternum orange with pubescence sparse, in shape of a “V” in basal half.

Elytra black; yellow fascia, in shape of an inverted “V,” extending from the scutellum to the anterior third, with a small groove on the posterior edge of the fascia, close to the suture. Apical half covered by silky white pubescence, irregular and more concentrated anteriorly. Elytral punctation sparse, the apices oblique with a small spicule at outer margin.

Profemora orange with apical third darkened. Meso- and metafemora with peduncle yellow, clubs black. Tibia basally black then orange toward the apices. Tarsi and Thoracic sterna red. Urosternites black.

Measurements, in mm, holotype female. Total length, 6.9; prothorax length, 1.5, greatest width of prothorax, 1.1; elytron length, 4.5; humeral width, 1.4.

Type material. Holotype female, BOLIVIA, Santa Cruz: Florida (4 km N Bermejo, Refugio los Volcanes, 18º06’S, 63º36’W, 1000–1200 m), 25–29.X.2011, Wappes & Skillman col. ( MNKM).

Etymology. Latin, praecipuum = particular, singular; alluding to the appearance of the species.

Discussion. Cycnidolon praecipuum sp. nov. resembles C. clarkei Martins & Galileo, 2007 , both key to couplet 4 in the key for South American species in Martins (2007), but is separated (comparison between females) by: the black head; flagellomeres bicolored, orange and black; pronotum with two gibbosities and pubescence sparse; humeri black; and apical half of the elytra sparsely pubescent. In C. clarkei : the head is red; flagellomeres are unicolorous, orange; pronotum densely pubescent with a small glabrous gibbosity; apical half of elytra densely pubescent.
