In comparing the syntypes of H. speculum from ZMHB and the holotype of H. cordieri from NMPC, no significant differences were found, hence all examined specimens of both species are considered conspecific. During examination, one of the syntypes of H. speculum was found to be male, allowing the male genitalia to be illustrated for the first time (Fig. 5).

Remarks:
The series of H. speculum (Klug) in the ZMHB originally contained three syntypes. Currently the series consists of two specimens. Only one of the specimens bears an original label with collecting data. During his work in the Berlin Museum in 1931, Hoscheck assumed this specimen to be the type-specimen and added a label with his suggestion, as it could be seen on the cited label-data above (vermutlich Typ = probably type). It is conceivably that one of the three existing specimens of the syntype series remained in Hoscheck’s collection, which was subsequently split into at least two parts: Institut Royal des Sciences Naturelles de Belgique, Brussels (ISNB) and Naturhistorisches Museum Basel, Switzerland (NHMB).
