Holotype. ♀: GUAT., ZACAPA, 2 km San Lorenzo , 5400', JUN 3–5, 1989, E. Giesbert ( FSCA) (Specimen point mounted, antenna and gender symbol affixed to paper point; support card; locality label; FSCA acronymic label; holotype label.)

Diagnosis: These small specimens (about 4.0 mm) are conveniently distinguished from congeners by having two small black setal tufts near the elytral apex.

Description: Length 4. 2 mm; width 1.3 mm. Form: Short oblong rectangulate. Integument: Mostly brown, cranial vertex with two brown setal tufts, legs yellow and with brown infuscations, elytra admixture of light brown and dark brown regions, elytral setae yellow, dark brown, or black, two black setal tufts near the elytral apex. Head: Eyes large, very convex; vertex between eyes broad. Thorax: Pronotal side margins with slightly-developed tubercle, anterior transverse depression not prominent, disc roughly sculptured and with coarse punctations; elytral side margins parallel to posterior four-fifths, then acutely rounded to apex; disc subcorrugated and coarsely punctate. Abdomen: Female pygidium transverse.

Variation: One specimen examined.

Natural history: The holotype specimen was collected in June, at 1646 m.

Distribution (Map 2): Known only from the type locality.

Etymology: The specific epithet is a Latin compound name formed from bi (= two) and barba (= beard). It refers to the two black setal tufts near the elytra apex.
