Apaeleticus Wesmael, 1845

Apaeleticus Wesmael, 1845: 166 .

Type species: Apaeleticus bellicosus Wesmael, 1885 , by subsequent designation of Ashmead (1900a: 22).

Comparative diagnosis

From all the other Nearctic Platylabini genera, Apaeleticus can be easily distinguished by this combination of characters: (1) strongly developed sternauli; (2) middle field of face strongly protruding ( Figure 7c ); (3) roughly irregularly cellular-wrinkled sculpture of propodeum with small, sharp teeth ( Figure 7a ); and (4) truncated apex of metasoma, with hidden sixth and seventh tergites retracted under the fifth ( Figure 7c ) ( Heinrich 1961, 1962b; Tereshkin 2009).

Range and diversity

Only two species in the Nearctic, of which only one occurs in the south-eastern United States, Apaeleticus americanus Cushman, 1926 .

Notes

There is a discrepancy in reporting the year of description of the genus, with Heinrich (1962b, p. 791) reporting 1844 and Yu et al. (2016) reporting 1845. The work by Wesmael (1845) has ‘1844’ printed on the cover of the article, but it was included in the journal Nouveaux Mémoires de l’Académie Royale des Sciences, des Lettres et Beaux-Arts de Belgique, volume 18, published in 1845, as reported by the cover of the journal itself. Therefore, the correct year of publication should be 1845.
