Genus Acerota Förster, 1856

(junior synonym of Inostemma Haliday, 1833 )

Acerota Förster, 1856: 107 , 110. Type species Acerota caryae Ashmead, 1887 , by subsequent designation by Muesebeck et al. 1951: 707. Junior synonym of Inostemma Haliday, 1833 ( Masner 1964: 146) .

Inocerota Szelényi, 1939: 121 . Type species Inocerota discessus Szelényi, 1939 by original designation.

Inocerota Szelényi, 1939 – Masner 1964: 148.

Remarks

Acerota was described by Förster as resembling Inostemma , except in the lack of a horn (cornutus) on the first metasomal tergite of the females. He did not include any species. Acerota caryae Ashmead, 1887 , was the first species described in the genus, and thus was automatically the type species. This species was transferred to Inostemma by Masner (1964), implicitly treating Acerota as a synonym.

Acerotella Masner, 1964 was erected to accommodate the remaining species of Acerota , with Acerota evanescens Kieffer, 1914 as the type of the genus. Kieffer described Acerota evanescens from a Förster nomen nudum in NHMW, and thus Förster’s concept of Acerota persisted and his specimens constituted the type material, albeit with the name Acerotella . The genus can be distinguished from Inostemma by the semicircular mesoscutellum in dorsal view ( Fig. 1D ).
