Preoccupied by Catillus Gray, 1847 . Piestopleura Förster, 1856: 144 . Type species Platygaster catillus Walker, 1835 by monotypy. Remarks The name Catillus , proposed by Förster 1856 , was preoccupied by a genus of snail ( Catillus Gray, 1847 ). Förster (1856) quickly proposed the replacement name Piestopleura in the addendum to Hymenopterologische Studien . This genus is defined by the strong lateral compression of the mesosoma, antero-posterior compression of the head, and dorsoventral compression of the metasoma. The type specimen of Platygaster catillus Walker, 1835 is in the NHMUK. The specimen in Vienna is an original exemplar, likely provided by Walker himself and used in the original description of the genus.
