Rivetina is a genus of mantises in the Mantidae family. Large mantises, females' wings are shortened, males fly well. They live in dry and desert landscapes. There are more than 30 species inhabiting the southern Mediterranean, the Middle East and Central Asia. 2 species are found in southern Europe.

Description

Large mantises, body length up to 7-8 cm. The head is approximately the same length and width. The forechests are clearly longer than the anterior basins, with deep oval supralinguistic flexion, usually with teeth on the edge. The front thighs are strong, with 4 inner and 4 outer spikes. Forelegs with 7-8 outer spines. The length of the wings in males is twice the length of the forechest, the ends of the wings barely cover the abdomen. The wings of females are shortened, not longer than the forelegs. The front wings are translucent, with a dark anal field. Hind wings with a black and white spot in the discoid field, their anal field more or less brownish. Subgenital plate of females with 2 spikes, adapted for digging the soil when laying eggs. Similar to mantises of the genus Bolivaria Stal, 1877, have large faceted eyes.

Taxonomy

A typical species is Rivetina baetica. This species was rather inaccurately described by Carl Peter Turnberg in 1815 as Mantis fasciata, and then independently by Jules Rambour in 1839 as Mantis baetica, and Rambury's description of the mantises of both sexes was very good. Both names were used in parallel until Ermanno Giglio-Tos in 1916 recognized the mantis M. baetica in M. fasciata. In 1904, William Forsell Kirby created the genus Omomantis for M. fasciata. Carl Brunner von Wattenville created the genus Fischeria for M. baetica. However, later it turned out that the name Fischeria in 1830 was given to the genus Tahini flies. Because of this, Chopar and Berlan identified the genus Rivetina for Mantis baetica. Instead, Giglio-Tos in 1916 began writing an article in which he created a new genus Eufischeriella for the species Eufischeriella fasciata. On May 11, 1922, he sent the article to the editors, but until his death in 1926 he continued to edit the article, adding new descriptions, so it was not published until 1927, and Eufischeriella was recognized as a younger synonym for Rivetina. Regarding the typical species, further researchers, in particular Boris Uvarov, noted that the description of Turnberg's authorship is so poor that no mantis can be accurately identified
