Description.

Head broader than high. Scapal basin concave, striate or punctate. TFC various, usually single and medially raised, sometimes double, downcurved along eye margin, or with branches upward extended to ocellar area. MS usually about 1 MOD. Pronotum with distinct and complete sublateral carina, sometimes incomplete or weak. Mesopleuron with broad episternal sulcus and scrobal sulcus. Metasoma usually with geminate puncures. T2 usually with median carina. T3 with three or five teeth; lateral teeth in some species can be merely angle-shaped. S2 with black spots usually fused medially, rarely separated by a narrow line, never connected to lateral margins.

Biology.

Species of Trichrysis  are known to be parasitoids of sphecid or crabronid wasps ( Dufour and Perris 1840; García Mercet 1911; Alfken 1915; Enslin 1921; Trautmann 1927; Grandi 1931, 1936; Danks 1971; Groot 1971; Lomholdt 1975; Morgan 1984; Kimsey and Bohart 1991; Asís et al. 1994; Kunz 1994; Strumia 1997; Rosa 2006). Recently Pärn et al. (2014) included also some Pompilidae  species as potential hosts for Trichrysis  .

Distribution.

Palaearctic, Afrotropical, Oriental and Australian Regions.

Key to Chinese species of Trichrysis  Lichtenstein

The key is mostly based on females. Males from China are known only for six species ( Trichrysis cyanea  , Trichrysis formosana  , Trichrysis lusca  , Trichrysis secernenda  , Trichrysis triacantha  , and Trichrysis yuani  sp. n.), and are recognizable by subtruncate apex of T3, shorter apical teeth and usually darker colouration dorsally.
