( Fig. 1 )

Type Material. Holotype female: labeled Risquetout Rd Pk. 15, French Guiana, ii-5- [19] 94, F. T. Hovore . Holotype deposited in the collection of the California Academy of Sciences , San Francisco , California, U.S.A. ( CASC). Five paratypes: 1 male and 1 female: same data as holotype; FRENCH GUIANA: 1 female, Route de Kaw, Pk. 47, ii-18-1994, F. T. Hovore, coll.; 1 male, Risquetout Rd, Pk. 4, i-27-28-1995, E. Giesbert, F. Hovore; 1 female, Route à Kaw, Pk. 38, viii-20-1995, E. Giesbert, J. Wappes . Paratypes deposited in JNRC and WFBC .

Diagnosis: The smooth and shining body surfaces, lack of conspicuous pubescence and the presence of three pairs of distinctive elytral markings make this species readily recognizable. It is somewhat similar in appearance to Enoclerus notatus (Klug) , but that species has the elytra distinctly, densely punctate and pubescent, and the head black.

Description (Holotype). Length: 5.52 mm. Width (across humeri): 1.75 mm. Conspicuously tricolored, smooth and shining above ( Fig. 1 ). Color: head testaceous with vertex broadly, faintly, irregularly brown; antennae with scape and pedicel testaceous, remaining antennomeres black; mouthparts testaceous, except mandibles black; pronotum uniformly testaceous; elytra black, with three pairs of conspicuous, eburneous markings; ventral surface with prosternum and mesosternum testaceous, metasternum black; anterior and middle legs with trochanters pale yellow, femora and tibiae testaceous (tibial carinae dark brown), tarsi brown; posterior legs tricolored as follows: trochanters pale yellow, femora brown, tibiae and tarsi nearly black; abdomen black. Head: nearly as wide as pronotum, impunctate, slightly swollen in front, except frons bears a pair of shallow, longer than broad, punctate depressions; surface with short, subrecumbent and suberect, inconspicuous pale setae, intermixed with longer, suberect, black setae; eyes small, located laterally, emargination subtriangular, shallow and broad; antennae short, flagellum sparsely, inconspicuously pubescent, length of flagellum subequal to combined length of antennomeres 3–5, pedicel subovate, antennomeres 3–6 filiform, 7–8 slightly expanded apically, club subflattened, last antennomere ovate, rounded apically. Pronotum: as long as broad, impunctate, faintly wrinkled anteriorly; surface sparsely clothed with short, subrecumbent and suberect, white setae and with long, erect and suberect, black setae; anterior transverse impression shallow, faintly indicated, bowed posteriorly; sides, when viewed from above, faintly sinuate anteriorly, well-rounded medially and curved posteriorly to the narrowed, transversely cristate posterior collar. Scutellum: bicolored, smooth and shining, sides nearly parallel, apex broadly rounded. Elytra: slightly broader across humeri than pronotal width across middle, slightly more than 2X longer than width across humeri; surface very finely, densely and inconspicuously roughened, but of shining appearance; pubescence consisting of short, suberect and subrecumbent, densely placed, fine, black setae that appear silvery at certain angles, and longer, suberect, stiff, scattered, black setae; eburneous markings large and irregularly margined: first pair ovate, longer than broad and located immediately behind front margin of elytra, extending beyond apex of scutellum; second pair ovate, longer than broad, obliquely positioned at about basal third of elytra, extending from near lateral margin to near elytral suture; third pair irregularly transverse, broader than long, located behind elytral middle, extending from lateral margin to elytral suture. Metasternum: swollen, surface nearly smooth and bearing an indistinct concentration of short, subrecumbent silvery setae on each side. Legs: femora of anterior pair slightly swollen, surface nearly smooth, clothed with short, subrecumbent and erect, silvery setae; tibiae roughened, carinae distinct, not quite attaining apex; middle and hind pairs of legs with femora less swollen, surfaces distinctly roughened, and with carinae and pubescence similar to those of front legs. Abdomen: shining, faintly punctate, indistinctly clothed with short, subrecumbent, fine, silvery setae; apical tergite slightly swollen and impunctate, apical margin semicircularly rounded, overlapping apical sternite and with a concentration of long and short black setae; apical sternite similar to apical tergite, but lacking apical pubescence.

Variation. Available specimens of this handsome species exhibit little variation.

Distribution: French Guiana.

Etymology. This species is dedicated to the memory of Frank T. Hovore, collector of most of the type series.
