( Figs. 11 , 14b , 15b )

Description. Moderate sized, 14–23 mm long; 3–5 mm broad; integument uniformly dark reddish-brown, pronotum and head similar in color to remainder of integument. Head moderately clothed with short, appressed, ivory-tawny pubescence, most dense around eye margins; interantennal impression weak; antennal tubercles not strongly elevated; antennae of female surpassing elytral apex by 1–2 antennomeres; antennae of male extending beyond elytral apex by about 3 antennomeres; last antennomere of female thickened, blunt, subequal in length to penultimate antennomere; last antennomere of male flattened, curved, distinctly longer than penultimate antennomere; antennomere four of both sexes 368 only slightly shorter than five; antennae strongly bispinose: spined mesally on antennomeres 3–8 and laterally on 3–9 or 3–10 in both sexes; antennal spines most pronounced on 3–5; antenna with moderate, appressed, ivory-tawny pubescence and sparse, erect hairs, especially mesally and apically on most antennomeres. Pronotum slightly broader than long in both sexes, slightly narrower at middle than elytral base; moderate ivory-tawny, appressed setae present (more abundant on sides); with poorly-delineated narrow, elongate longitudinal callus extending to near anterior and posterior margins, with two small, round, poorly delineated calli posterolaterally (one on each side) and two small, round, poorly delineated calli anterolaterally (one on each side); large, unevenly sized punctures present, except on calli, becoming much smaller at sides in males; larger and sparser at sides in females. Prosternal intercoxal process pronounced, broad, glabrous, protruding posteriorly beyond plane of procoxae, acutely declivous. Elytron with moderately dense, symmetrically patchy ivorytawny, appressed pubescence; very few erect or suberect setae present; elytral apices strongly bispinose, outer spine thicker; twice as long, slightly angling away from sutural spine; weakly arcuate between spines. Elytron with dense but mostly non-contiguous, large, deep punctures, becoming shallower posteriorly. Scutellum rounded posteriorly and with moderate to sparse ivory-tawny pubescence; glabrous longitudinally along middle. Legs moderate in length; hind femora extending into plane of fourth ventrite; pubescence of femora ivory-tawny, sparse, patchy; few sparse, erect hairs on tibiae and femora. Mesofemoral apices moderately spined mesally, weakly spined laterally; metafemoral apices with moderate spines mesally and laterally (apicomesal spine slightly longer than apicolateral spine). Abdomen with ventral pubescence ivory-tawny, more dense at sides, sparse at middle; last ventrite of both sexes broadly rounded apically, without modification.

Etymology. Michael Ivie (WIBF) recognized this as a potential new species in 1989 (based on a label notation). Due to this and the fact that he collected some of the type series, I am pleased to dedicate this species to him. The epithet is a noun in apposition.

Discussion. The strongly bispinose antennomeres combined with the brown integument with symmetrical patches of ivory-tawny pubescence on the elytra distinguish this species ( Fig. 11 ) from all other Elaphidion in Hispaniola. Sexual dimorphism is pronounced with regard to the antennae: in males they extend beyond the elytral apices by approximately 3 antennomeres; in females they extend beyond the elytral apices by 1–2 antennomeres; the last antennomere in males is flattened, curved, and distinctly longer than the penultimate; in females the last antennomere is thickened, straight, blunt at apex, and subequal in length to penultimate. In males the prothorax is densely, confluently micropunctate at sides and ventrally in front of procoxae; in females punctures are large and sparse at the sides of the pronotum and absent in front of the procoxae. There is no apparent sexual dimorphism in antennal spines; both sexes are strongly bispinose on most antennomeres ( Fig. 14b ).

One specimen in CMNH was collected in Cuba, however, examination of the Zayas collection by E. H. Nearns ( Nearns et al. 2006) turned up no additional specimens from that island. The remaining eight specimens are from the Dominican Republic .
