( Figures 5 View Figure 5 a-d)
Description. Male. Length 10.0- 18.5 mm (measured from vertex to elytral apices), width 4.5-5.5 mm (measured across humeri). Habitus as in Fig. 5a View Figure 5 . General form elongate-ovate, moderate-sized. Integument ferrugineous with brown, white, and testaceous pubescence; pronotum with distinct longitudinal, testaceous vitta at center; scutellum testaceous; elytra densely speckled with white and testaceous pubescence.
Head with frons elongate, about 2 times width of lower eye lobe ( Fig. 5c View Figure 5 ). Eyes with lower lobes oblong; narrowest area connecting upper and lower eye lobes about 3-4 ommatidia wide. Genae elongate, a little shorter than lower eye lobes.
Antennae about 1.3 times longer than body; antennal tubercles prominent, moderately separated; tubercles armed at apex with short blunt tooth; scape robust, gradually expanded to apex, slightly clavate, a little shorter than antennomere III, about as long as IV; basal 2/3 of scape transversely rugose; antennomere III slightly curved; antennomeres IV-X becoming progressively shorter, XI a little longer than X; basal 1/2 of antennomeres IV, VI, VIII, and X with distinctly lighter pubescence.
Pronotum distinctly conical, wider at base, transverse, about 1.5 times as wide as long, sides nearly straight, slightly arcuate, without lateral protuberances ( Fig. 5a View Figure 5 ); disk with three feebly elevated tubercles, sometimes absent; disk shallowly, sparsely punctate.
Scutellum transverse, sides straight, oblique, apex rounded.
Elytra about 1.6 times as long as width at humeri ( Fig. 5a View Figure 5 ), about 4.4 times as long as pronotal length, about 1.4 times broader basally than pronotum at widest (at base); sides nearly straight, gradually rounded to apices at apical 1/3, elytral apices individually rounded; base of each elytron with a feeble, broad gibbosity; basal 1/3 of elytra with dense punctation, surface coarsely punctate; humeri prominent, anterior margin arcuate, angle with broad, obtuse tubercle.
Venter with procoxae large, globose, not uncate ( Fig. 5b View Figure 5 ); narrowest area of prosternal process between procoxae about 1/5 as wide as procoxal cavity; apex of prosternal process subtriangular. Mesosternal process about as wide as mesocoxal cavity; mesosternal process deeply emarginate. Fifth sternite about twice as long as IV, apex emarginate.
Legs moderate in length; profemora robust, transversely rugose at base; meso- and metafemora clavate apically; meso- and metatibiae distinctly expanded apically; meso- and metatibiae with distinct, longitudinally depressed areas on both inner and outer surfaces ( Fig. 5d View Figure 5 ); metafemora about 1/3 as long as elytra.
Female. Unknown.
Type Material. Holotype, male ( Fig. 5 View Figure 5 a-d), “ ECUADOR: Napo Pr., 24 km E Atahualpa, 09-12 Sept 2004, F. T. Hovore, coll.” ( CASC). Two paratypes: one male, same data as holotype ( CASC); one male, “ Ecuador : Napo, Res. Ethnica Waorani, 1km S. Okone Gare Camp, Trans. Ent. 3 Oct. 1996, 220 m. 00 o 39’10”S 076 o 26’W, T. L. Erwin, et. al.” ( ENPC). GoogleMaps
Etymology. We are pleased to name this species in honor of Ubirajara R. Martins, for his friendship and many contributions to the study of Neotropical Cerambycidae . The epithet is a noun in the genitive case.
Diagnosis and Remarks. This species is distinguished from its congeners by the combination of the following characters: pronotum with longitudinal, testaceous vitta at center; elytra densely speckled with white and testaceous pubescence; and procoxae in males not uncate. This species is described from three male specimens and female specimens are unknown. Nothing is known about the habitat and behavior of this species. The geographic range of this genus (previously known from Bolivia and Brazil) is extended to Ecuador .
