Original type series

Syntypes: ♀♀, ♂♂, (precise number unknown) (MZPW).

Heinrich (1938: 125) described the species based on “ Nombreux exemplaires [= numerous specimens]” without clearly designating one of them as the name-bearing type. Initially, Rousse et al. (2013: 21) correctly referred to the types as “ syntypes ”, without designating a lectotype. However, the same authors refer to the specimen depicted in figs 5–6 of their work ( Rousse et al. 2013: 22–23) as the “ holotype ”. The employment of the term “ holotype ” does not constitute a valid lectotype designation ( ICZN 1999: article 74.5, 74.7). Moreover, one of the specimens belonging to the type series bears a red label that reads verbatim: “ aes Lectotypus Sawoniewicz ‘77 ” ( Rousse et al. 2013: 23, fig. 6f). Unfortunately, there is no record of a published work clearly designating a lectotype for this species, and therefore the label does not constitute a valid lectotype designation ( ICZN 1999: article 74.5). A more in-depth study of the MZPW collection will be required prior to the designation of a lectotype; therefore, for the moment, the type specimens should be referred to as syntypes ( ICZN 1999: article 73.2).
