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.
