Maxillae and labium mainly testaceous, only distal palpal segments dark brown with metallic blue green reflections. Mandibles sexually dimorphic; in male, surface mainly testaceous, only teeth shiny green; in female, surface only testaceous in basal half, apical half and teeth shiny to violet green; mandibles symmetrical, four teeth distad of molar, apical tooth longest, first and third tooth coequal in length, second tooth shortest; first and second teeth without a gap between them in male, gaps between three intermediate teeth wide in female. Antennae 11 segmented; scape dorsally shiny green, ventrally testaceous with a single subapical sensory seta; antennomeres 2-4 shiny green, glabrous except for a few, short erect setae along their length and distally; antennomeres 5-11 dull brown, sheathed with dense short sensory setae. Prothorax. Figs 14C, 14D, 15C, 15D. Pronotum metallic copper brown with green reflections. Proepisterna shiny copper, surface wrinkled dorsad. Prosternum shiny green. Pronotum glabrous except for short, decumbent, white setae distributed in several, irregular rows inside lateral margin medially directed, originating close to and lying in a narrow band nearly impinging on lateral suture, in a sparse narrow band transversely and anteriorly oriented distinctly removed from anterior margin, and in a sparse narrow band laterally oriented on each side of midline extending nearly to the narrow posterior margin; transverse submarginal sulci distinct, anterior sulcus shallow, posterior sulcus deeper and deepest at posterior angles; transverse rugae within broad anterior margin irregular and shallow, interrupted at middle by an irregularly arranged pattern, within posterior margin more distinctly and deeply engraved especially medially and extending onto midline; surface sculptured by fine, transverse rugae angled on disc and interrupted by a finely engraved longitudinal midline, and more finely and irregularly sculptured elsewhere. Proepisterna glabrous except for white, erect and appressed setae arising from small setigerous punctures scattered over the surface near ventral margin in female, over ventral half of the surface and near the posterior margin in males. Prosternum glabrous. Pterothorax. Figs 14C, 15C. Mesepisterna glabrous except for a few appressed setae near ventral margin; female coupling sulcus represented by a small depression medially situated, a distinct groove extends only dorsally from pit, surface smooth below pit. Mesepimeron with a few sparse appressed setae. Metepisterna with scattered appressed setae, more abundant in male than female. Prosternum and mesosternum glabrous, smooth to slightly wrinkled; metasternum glabrous except for long, dense white appressed setae laterad, surface smooth mesad and coarsely sculpted laterad where setae originate. Scutellum triangular, shiny cupreous. Legs. Figs 14A, 15B. Segmentstestaceous brown with metallic brown green reflections. Coxae shiny metallic brown green; trochanters shiny testaceous; femora and tibiae testaceous with metallic green reflections anteriorly; tarsomeres dark metallic brown; white, appressed setae on front and middle coxae, and laterally on hind coxae; erect setae and suberect closely spaced in several regular and irregular rows on all femora; setae widely spaced in a few rows on all tibiae; middle tibiae with patch of appressed setae dorsally along distal half; tarsomeres with short scattered setae on ventral surface; distal tarsomeres with two asymmetrical rows each with a few to several small, erect setae; an erect subapical seta present only on front trochanter, absent on middle and hind trochanters; males with dense pad of erect setae ventrally on proximal three tarsal segments; tarsal claws small. Elytra. Figs 14A, 15A. Form narrow in male, broadened slightly distad and broadest at outer apical angle in female; posterior margins evenly rounded, apices separately rounded; sutural spine tiny in male, small in female, feebly withdrawn from apex; posterior margins finely microserrulate. Surface finely granulate, impunctate, numerous small, irregular, metallic flecks of various sizes comprised of blue or blue green flecks scattered over a cupreous or coppery green background; setigerous punctures with short, erect, transparent setae indistinct in subsutural rows on disc, but distinct at elytral base, and at inner humeral angles, each surrounded by a metallic fleck slightly larger than flecks elsewhere on elytra; surface slightly depressed in humeral area and on disc creating a slight but distinct raised area basally. Elytra unmarked in most specimens, only faintly marked in others, or marked with more distinct tawny lunules in a few; elytral ground color cupreous in most specimens, coppery green in others or green in others; faint elytral markings infuscated with metallic blue green flecks; specimens with the most extensive infuscated markings appear immaculate, while others have faint and indistinct markings; faint markings comprised of a humeral lunule reduced to its extremities, a middle lunule terminating near the suture in a broad hook never anteriorly recurved, and an apical lunule usually reaching the suture. Elytral epipleura testaceous except for narrow, metallic green to copper green band along dorsal margin. Abdomen. Figs 14B, 15E. Surface of 1st-5th sterna shiny black with green reflections, 6th sternum entirely shiny black to black brown; posterior margins of male 3rd-5th sterna and female 3rd-4th sterna narrowly black; posterior margin female 5th sternum broadly black; 3rd-5th sterna medially smooth with scattered, fine, erect setae in both sexes; male 1st-6th sterna and female 1st-5th sterna laterally covered with dense, scattered, appressed white setae and roughened from setal punctures; male 6th sternum glabrous medially with a broad, deep concave notch; female 5th sternum with moderately raised, transverse wrinkles interrupted by a short, wide membranous band along midline extending anteriorly to middle of sternum from a wide transverse membranous wedge along posterior margin; female 6th sternum entirely glabrous, posterior margin with a row of 6-10 erect spines and a large lateral gibbosity on each side. Male Genitalia. Figs 14E, 14F, 14G. Shape narrow near base, widening gradually and uniformly broad in middle three-quarters, narrowing gradually distally with neck short and wide, apical hook inner and outer angles evenly rounded, tip short and acutely angled to aedeagus. Aedeagus inner sac sclerites: stylet thin and straight to slightly bent distad; shield rounded distad; large tooth wide and pointed at tip with large root and large dark fields; arched piece short and narrow; spine field within aedeagus neck short and thin.

Fig. 22. DOMINICAN REPUBLIC: Pedernales Province, Sierra de Baoruco at higher elevations in grass and pine habitats typical of the locality known as Aceitillar. Localities include: 37 km N Cabo Rojo at 1500 m (more precisely 1560 m); El Aceitillar ca. 35km NNW Cabo Rojo at elevations from 1250 m to 1430 m. This species in likely distributed throughout the Sierra de Baoruco at higher elevations in areas of red, bauxite soils in habitats with pines and grasslands.
