Enoclerus gilli Rifkind , n. sp.

( Fig. 8 )

Type specimens. Holotype male: Guatemala, Zacapa, 6 km S. La Unión, 1550 m, May 27, 1997, E. Giesbert, coll. Holotype deposited in CNC. Paratype: 1, Guatemala, Zacapa, 3 km S. La Unión, 6–vi–1991, B. D. Gill, coll. Paratype deposited in JNRC.

Diagnosis. Most similar to E. semiochraceus (Chevrolat) , its probable sister species. Enoclerus gilli , by comparison, has a broader, more transverse midelytral fascia, and lacks the distinctive band of rusty pubescence that encircles the elytral basal tumescences in E. semiochraceus .

Description (Holotype). Length: 8.0 mm. Color: black; antennomeres 1 and 2 in part reddish testaceous; mouthparts castaneous; elytra with a broad, transverse, pale orange fascia at middle, complete to lateral margins and across sutural bead. Head: antennae robust; eyes moderate in size; surface densely, minutely but shallowly granulate-punctate, rather densely covered with short, subrecumbent orangish setae, intermixed with fewer longer, erect orangish setae. Pronotum: campanulate; about as long as broad, narrower than elytra at base; anterior margin shallowly emarginate at middle; transverse impression moderately distinct, broadly U–shaped at middle; disk subflattened above; basal collar broad; surface sculpted as on head, rather densely vested with short and medium length, anteriorly oriented, suberect orangish setae, interspersed with a few medium length black setae; vestiture somewhat more thinly arrayed posteriorly at sides. Elytra: elongate (ratio of length to width 31:16); anterior margin bisinuate; humeri distinct, with umbones prominent, rounded; sides subparallel, slightly inflexed at anterior 1/3, widest at middle, arcuately rounded posteriorly to separately rounded, slightly dehiscent apices; subbasal tumescences gibbous, prolonged posteriorly but rounded above, without tubercles; disk subflattened, apical slope moderately precipitous; surface on black integument shallowly granulate, rugulose and occasionally dimpled; surface of pale median fascia rugulose and rather densely, minutely and deeply punctulate; each elytron bearing 3 or 4 longitudinal striae; vestiture as follows: scutellum densely set with stramineous setae; anterior margin with a sparse array of short reclinate and medium length erect, pale orange setae that extends posteriorly at middle beyond scutellum; lateral margins posterior to umbones with a small triangulate patch of reclinate orangish setae; basal black band with a dense covering of short, erect black setae and somewhat fewer longer, erect black setae; median orange band with a moderately dense covering of short, subrecumbent, pale orange setae, intermingled with longer, suberect and erect setae of the same color; posterior 2/5 anteriorly with a transverse, hourglass–shaped fascia of dark pilosity similar in composition to basal black band, posteriorly with a covering of orange setae as on median band, complete to apices. Mesosternum: posterior median process distinctly elevated apically. Metasternum: convex; surface roughened, densely set with white setae; anterior median process sulcate. Abdomen: shining; sparsely set with white setae; visible sternite 6 with hind angles rounded, posterior margin slightly emarginate at middle, surpassed by visible tergite 6, which has posterior margin rounded. Legs: robust.

Variation. The paratype female measures 8.35 mm in length. It has visible sternite 6 rounded at apex, but is otherwise similar to the holotype.

Etymology. The specific epithet is a patronymic honoring its discoverer, my fellow coleopterist Bruce Gill.
