Diagnosis.

Externally, the species is similar to H. miwai , H. klapperichi , H. guizhouense and H. alexpuchneri , both in colouration and shape and differs mainly in the much larger black elytral spot, occupying the apical two thirds of each elytron. For differences with H. parvioculatum , see diagnosis under that species.
