Systematic notes	[from: Strumia, 2009] Only three species were previously recorded from the Mediterranean region: Trichrysis cyanea (Linnaeus, 1758), Trichrysis lacerta (Semenov-Tyan-Shanskii & Nikolskaya, 1954) and Trichrysis scioensis Gribodo, 1879. Trichrysis cyanea is widespread in the Palaearctic region,Trichrysis lacerta is known from Greece, Cyprus, Turkey, the Caucasus and Egypt, whereas Trichrysis scioensis Gribodo, 1879 is an Afrotropical species reaching also Egypt and Palestine (Lisenmaier 1999). Trichrysis cypria (Mocsáry, 1902) from Cyprus is a synonym of Trichrysis lacerta. Linsenmaier (1959: 170) found that the name Chrysis cypria Mocsáry, 1902 was preoccupied by Chrysis pyrrhina cypria Buysson, 1897 from Cyprus (Buysson 1897: 555, pl. 19, fig. 11), and renamed the species as C. devia. More recently, Linsenmaier (1968) discovered that the same species had been previously described by Semenov-Tyan-Shanskii and Nikolskaya (1954: 122) as C. lacerta (thus lacerta is the valid name, devia and cypria are synonyms: Linsenmaier 1999: 227).
