Remarks.

The data from the labels found with the ZMH specimen matches with the information presented by Simon in his paper. In the original description, the specimen described is supposed to be a male (the male symbol is written at the beginning of the description) but the description mentions the genital plate: "Area genitalis rufula, plana, obtuse triquetra, postice plagula transversa parva et nitida munita" and does not include the male palp; hence we conclude that the male symbol is a typographical error and the type specimen is a female. Miller (2007: 259) erroneously declared the genus Zilephus and the species Zilephus granulosus nomina dubia.
