Type specimens. Holotype male (?): Panamá, Panamá Pr., Pr. Natl. Metropolitano, 19 January, 1996, Leg. F. Oedegaard, canopy sample. Holotype deposited in CSCA. Paratypes: 2, same data as holotype, except 26 December, 1995; 1, same data as holotype except 23 December, 1995. PANAMÁ: Panamá Province: 2, Cerro Campana, June 1, 1983, E. Giesbert, coll.; 1, Cerro Campana, 2200', May 18–19, 1984, E. Giesbert, coll. COSTA RICA: 1, Puntarenas Province, Paso Real, May 10, 1996, E. Giesbert, coll. Paratypes are deposited in CSCA, LACM and JNRC.

Diagnosis. No other Central American Enoclerus species exhibits elongate, shining elytra marked with four pairs of yellow maculae and fasciae. The new species seems most similar to E. miniatus (Spinola) from South America, but that species is less gracile, has much coarser, more densely arranged elytral punctation, a unicolorous head and pronotum, and black forelegs.

Description (Holotype). Length: 3.95 mm. Color: black; mouthparts, antennae, labrum, clypeal region, anterior margin of pronotum, and forelegs, reddish–testaceous; second and third pair of tibiae and tarsi castaneous; elytra with four sets of yellow markings as in Fig. 14 ; antemedian fascia narrowly incomplete laterally before epipleuron; median and subapical fasciae complete just to epipleuron. Head: antennae rather robust; surface shining and sparsely punctulate, set with subrecumbent, posteriorly oriented whitish setae, intermixed with a few longer, erect dark setae. Pronotum: subcampanulate, about as broad as long, narrower than elytra at base; transverse impression distinct, broadly V–shaped at middle; disk subflattened at middle; surface shining, punctation as on head, except collar more densely, coarsely punctate; vestiture thin, suberect and cinereous, with an admixture of fewer, longer, erect dark setae; posterior pronotal slope shallow. Elytra: elongate (ratio of length to width 25:11); broadest at posterior 2/5, dorsoventrally compressed, sides gradually expanded behind suboblique humeral angles, then slightly, gradually inflexed at anterior 1/3 before gradually expanding to maximum width at posterior 2/5, and finally converging arcuately and very gradually to separately rounded, dehiscent apices; epipleuron rather broad, visible in lateral view from base to apices; subbasal tumescences obsolete; posterior slope gradual; surface shining, shallowly dimpled, rather sparsely set with small, round punctures, these being darkened and conspicuous within the yellow marked areas; vestiture inconspicuous: short, fine, subrecumbent and dark on dark areas; short, fine, subrecumbent and yellow on yellow maculae and fasciae, with an intermingling of longer, more robust black setae throughout. Mesosternum: posterior median process not distinctly elevated. Metasternum: moderately convex, shining, sparsely setose; anterior median process not elevated. Abdomen: shining, sparsely setose, sculpted with a few coarse but shallow punctures; visible sternite 5 with hind angles rounded, posterior margin slightly, arcuately emarginate at middle; visible sternite 6 concave, sides oblique, hind margin subtruncate; slightly surpassed by visible tergite 6, which has the posterior margin rounded; setal daggers absent.

Variation. Length ranges from 3.90 mm to 6.45 mm. The female has visible sternite 5 subtruncate posteriorly, visible sternite 6 and visible tergite 6 conjointly rounded posteriorly. One specimen shows the yellow humeral maculae narrowly confluent with the post basal fasciae.

Etymology. The specific epithet ( urbanus = Latin for "of the city") refers to the presence of this species in the Parque Nacional Metropolitano, a wildlife refuge located within the capital city of Panamá.

Distribution. Known from Panamá and southeastern Costa Rica.

Biology. Some specimens were taken in a canopy sample in the Parque Nacional Metropolitano, which is characterized as tropical semi–deciduous dry forest.
