Figs. 2D , 3B .

Type locality: Quarry near Rubies, La Cabrúa fossil site, Sta. Maria de Meià , Sierra del Montsec, Lleida Province, Spain .

Stratigraphic horizon: Calcaires lithographiques à Plantes et Vértébres de la Pedrera de Rubies Fm., Barremian, Lower Cretaceous ( Martín−Closas and López−Morón 1995).

Derivation of the name: After Indíbil, an Iberian pre−roman leader from Lleida.

Material.— Holotype IEI LC 4636 , part and counterpart of a beetle without legs.

Diagnosis.—From most part of species of the genus differs in bigger body size. From B. punctatus Hong, 1982 differs in bigger ratio between length and wide of elytra, from B. impressus Ren, 1995 differs in wider pronotum, and from B. rostratus Ponomarenko, 1969 in presence of clear neck−like constriction.

Description.—Measurements: length 6.2 mm; width 2.9–3.0 mm; elytra length 4.0 mm. Body rather small and flattened. Head somewhat longer than wider with comparatively short mandibles, epicraneal suture well expressed; genae and temples shorter than eyes, occiput truncate, temples not projecting laterally; vertex with two oval flat prominences; neck−like constriction clear. Eyes large and strongly convex. Pronotum transverse, about twice wider than longer, propleura somewhat flattened. Prosternum almost subquadrate, slightly shorter than mesosternum and somewhat as long as metasternum. Procoxae rounded and contiguous. Mesosternum somewhat longer than wider at posterior edge. Mesocoxae rounded. Metasternum nearly quadrate, longitudinal and transverse sutures not well expressed. Metacoxae subtriangular, narrowing laterally and extended over midlenght of first ventrite. Abdomen with 5 visible flattened ventrites with no marked relief. Last ventrite about 1.7 times as long as previous one. Elytra about 2.8 as long as wide, epipleura rather wide, narrowing posteriorly in its last 1/3. Body without distinct puntuation.
