    Descrizione originale [From: Strumia F., 2009 - Trichrysis baratzsensis sp. nov. (Hymenoptera: Chrysididae) from Sardinia. Zootaxa 2318: 589–595 (2009).]

    Diagnosis. Distinctive features of the new species (Fig. 1) are the shape of the distal margin of TIII, the absence of the pronotal lateral carina, the carina around the compound eye, and the two isolated and not touching black spots on STII, that are, on the contrary, touching or fused together in all other studied species of the genus (see also the key at end of this paper).

    Description. Body length 4.3 (paratype) to 5.9 mm (holotype and paratype). Colour. Body blue-green as in other species of the genus. Dark blue at base of central part of mesonotum, between ocelli and at base of TII; body pubescence short and white. Fore wings slightly brown-stainted. Antenna black in colour with pedicel and FI metallic green. Legs metallic green; first tarsomere of anterior leg metallic green as tegulae. Head. Elevated carina all around compound eye (Fig. 7). Facial cavity deep, finely, irregularly and transversally striate; malar space as long as FII. Mandible simple, without additional teeth. Thorax. Pronotum lacking lateral carina and with a weak groove in the middle of anterior edge. Punctures on mesonotum and scutellum large with smooth shining areas and smaller punctures in between. Radial cell of fore wings narrow, long and closed. Propodeal angle obtuse, pointing backward. Abdomen. Anterior declivity of TI with two grooves delimiting two anterior humps. Punctures on TII smaller than on thorax, becoming smaller distally. TIII saddled in shape, with smaller punctures than TII. Distal margin of TIII tridentate; spaces between teeth strongly convex, almost forming additional obtuse teeth (Figs 1, 5). Sternal black spots on SII small and isolated from one another: not touching as in other Mediterranean species.
    Sinonimi e sottospecie  
    Note sistematiche [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).
