remarks: 

The type series of Milichiella bimaculata consists of an unspecified number of males collected by Becker on Gran-Canaria. The types may be lost. There are 2 specimens from Tenerife in ZMHU, which were later labeled as types, but which do not bear the Becker's typical identification label and which do not belong to the type series if Becker
