Eburodacrys santossilvai sp. nov.

( Figs. 14–20 )

Female. Integument mostly reddish-orange; antennal tubercles, area surrounding elytral eburneous callosities and apex and spine of femora darker; apex of mandible, and pronotal tubercles black.

Body covered by long, erect, sparse setae. Head shallowly, finely, densely punctate. Distance between superior eye lobes about 3.5 times width of one upper lobe. Apices of genae rounded. Antennae short, only reaching apical ninth of elytra; with fine yellowish pubescence, denser toward apical antennomeres; with long (longer than width of an antennomere), sparse setae, especially on inner side, gradually shorter, sparser toward apical antennomeres; scape curved, slightly excavated dorsally and ventrally at base; antennomere III and basal half of antennomeres IV and V with longitudinal sulcus. Prothorax with small median lateral tubercle, acute at apex. Surface of pronotum with transverse wrinkles and deep punctures; disc with two elevated tubercles, rounded at apex, and posterior median gibbosity. Prosternum with transverse sulcus. Mesoventrite without tubercle. Elytra 3.75 times longer than prothorax; surface of anterior half with coarse, dense punctation, at posterior half punctations decrease and at apex there is no punctation. Each elytron with three eburneous callosities: one anterior, elliptical and two posterior, elliptical, contiguous, lateroposterior beginning at level of apex of inner posterior, both of same size. Apex of elytra with long external spine, longer than pedicel; at suture with small dentiform projection. Epipleura with tooth near base of elytron.

Profemora subfusiform, meso- and metafemora slender and elongate; apices of meso- and metafemora with long inner spine (longer than elytral spine).

Variability. Some specimens are more reddish, the area surrounding eburneous elytral callosities, apex and spine of femora and elytral spine is darker, but not black, this area can be extended joining the anterior and the posterior callosities. In some paratypes the eburneous callosities are more elongate and the antennae reach elytral apex at base of antennomere XI.

Measurements, in mm. Holotype female. Total length, 19.5; prothorax length, 3.7; prothorax width at its widest point, 4.3; elytral length, 13.6; humeral width, 5.1. Paratypes females, n = 9. Total length, 14.80±2.81; prothorax length, 2.90±0.46; prothorax width at its widest point, 3.24±0.52; elytral length, 10.62±1.89; humeral width, 3.70±0.73.

Etymology. The specific name is a genitive patronym in honor of Antonio Santos-Silva, for his friendship, research assistance, and in recognition of his contribution to the knowledge of cerambycid fauna.

Remarks. Eburodacrys santossilvai sp. nov. is similar to E. fortunata but differs from it in having the surface of the disc of the pronotum with transverse wrinkles and deep punctures; the lateral tubercles of pronotum, femoral spines and elytral spines reddish-orange; elytra without visible costae between anterior and posterior callosities; posterior eburneous elytral callosities joined, separated by a distance smaller than the width of a callosity. In E. fortunata , the disc of the pronotum has only transverse winkles, without punctures; the lateral tubercles of the pronotum, femoral spines and elytral spines are black; the elytra have visible costae between anterior and posterior callosities; the posterior eburneous callosities are separated by at least a distance equivalent to the width of a callosity. Eburodacrys santossilvai sp. nov. is also similar to E. asperula and E. callixantha but differs from them in having the lateroposterior eburneous callosities starting behind the inner posterior callosities and having the apex of the elytra obliquely truncate (In E. asperula and E. callixantha , the posterior eburneous callosities start anteriorly at the same level and the apex of the elytra is truncate).
