DIAGNOSIS: In specimens of this species the elytral humeral umbo is very prominent and the elytral discal setal tuft is a single diagonal patch (fig. 171); the setae of the tuft are all decumbent and directed anteriorly.

DESCRIPTION: Size: Length 4.5 mm; width 2.1 mm. Integument: Black. Vestiture: Head, prothorax, elytra, and protibia vested predominantly with dark setae, pterothorax, femora, and meso­metatibia vested predominantly with pale setae; tarsi vested with dark setae; epipleural margin vested profusely with pale setae; elytral setal tuft comprised of one elongate diagonal patch whose setae project anteriorly. Head: Width across eyes narrower than width across pronotum (30: 35); finely punctate, interocular depression and frontal umbo indistinct; eyes subspherical, moderately convex; antenna (fig. 69) shorter than pronotum (30:35). Thorax: Pronotum as figure 251, as long as wide (35:35), finely sparsely punctate, side margins moderately arcuate, anterior transverse depression indistinct, considerably narrower than width of elytra across humerus (35:45); elytra strongly convex in posterior half, depth at humerus 15, greatest depth in posterior half 23. Abdomen: Pygidium with posterior margin evenly arcuate; tegmen as in figure 138; parameres broad at base.

NATURAL HISTORY: Specimen were collected in May, June, July, and December.

DISTRIBUTION (map 21): Known only from central Costa Rica.

ETYMOLOGY: The Latin protenus (forward) is used to refer to the forward­directed setae of the elytral setal tuft.
