COMMENT.
When the name Coleoptera was introduced, Strepsiptera had not been discovered.
Because of this, the name Coleoptera sensu
De Geer 1774 can be formally regarded as a non-monosemantic name, which can be
ascribed to Elytrophora
Packard 1883;
really, some authors used the name Coleoptera in such meaning – see .
But from the literature of XVIII-XIX centuries we can proceed, that if
Stepsiptera would be known to De Geer, he would not include them to his
Coleoptera. During the first half of the XIX century, representatives of
Strepsiptera were placed either to a separate order (Kirby 1813, et al.),
or to Hymenoptera (Rossi 1793, et al.), or to Diptera (Lamarck
1816, et al.), or to other orders, but not to Coleoptera; only
beginning from the second half of the XIX century their place within or
near Cleoptera was determined (Lankester
1877 et al.). So Coleoptera can be regarded as a monosemantic name,
being not a senior synonym of Elytrophora.
