AbstractAllied to H. guineensis and Sjöstedti. Recognizable by having four black spots in the fulvous basal half of the elytra (two on each elytron), which spots are by two and two united posteriorly by an infuscation of the 4th interspace.
Length 14,5 mm. — Elongate, depressed, shining; fulvous, the head with mandibles (the throat excepted), a broad streak along the middle of the pronotum (anteriorly as broad as the neck), the basal and lateral edges of the pronotum, the scutellum, and the basal edge and larger (apical) half of the elytra black, the latter with a faint bronze hue; the fulvous basal portion of the elytra shows four black spots, two on each elytron: the larger, foremost one between the 3rd and 4th striae, the smaller hindmost one between the 5th and 6th striae, both united posteriorly by an infuscation of the 4th interspace, the hindmost one moreover united with the black apical half at the 6th stria; the space between these black spots and the black apical half is occupied by an almost inconspicuously swollen yellow spot of a somewhat trapezoidal shape, extending over the 4th, 5th and 6th interspaces and deeply entering into the black of the apical half; the fulvous colour of the basal half is slightly prolonged backward along the lateral margin. The antennae are reddish fulvous, with the exception of the club which is black. The legs are fulvous, with the trochanters, the apical third of the femora and the basal and apical fourth of the tibiae black; the tarsi are dark pitchy, the basal half of the clawjoint fulvous.
