Redescription.

Size of the male: length 9-11 mm; width 3.3 mm. Size of the female: length 14-16 mm; width 4.6 mm. General colour testaceous-yellow. Antennae with segments 1-3 yellowish, segments 4-8 brown and 9-11 white. Testaceous legs. Elytra with darkened, almost black, sutural and apical areas as well as sides including epipleura. All the body is clothed in short golden tomentum. The first sternites are testaceous-yellow, the last two are black in the males and yellow in the females. Head subquadrate, with prominent eyes. Long reddish mandibles, slightly darker in the inner margin, the external border arched and covered in long golden setae, extending from the base and almost reaching the apical part. Long slender maxillary palpi, the last segment cup shaped and truncate at apex. Labial palpi longer than the mandibles, the second segment reaching the apex. Frons with a longitudinal groove. Antennae not long, only just reaching the apical fifth of elytra in males, scapus strongly punctate and enlarged distally. Antennomere 3 long and narrow, flattened, after antennomere 4 they are slightly dilated in the external apical part. Pronotum subcylindrical, slightly wider than long (70/80) at the level of the strongly rounded lateral protuberances. Triangular scutellum with slightly rounded apex, punctate and with short golden tomentum. Long narrow elytra, rounded and very prominent humeri, narrowed at the middle and dehiscent at apex, which is rounded in each elytron. Bordered suture. Discal area with a depression from elytral base to the centre. The elytra leave the last two abdominal segments uncovered. Mesosternum and metasternum short and broad, with a very broad, subquadrate mesoepisterna, the mesocoxal cavities well separated by an angular process. Wide abdomen in females, slightly more so than the elytra, the tegument of the five visible sternitesis translucid, through which around fifty eggs can be seen in the holotype specimen, which Lacordaire (1869) probably mistook for "scattered white spots". The sternites are finely punctate and clothed in short golden tomentum. Short robust legs, femora widened at middle, straight tibiae dilated at apex.
