Genus Adelencyrtus Ashmead, 1900

Epitetracnemus Girault, 1915: 164 , syn. nov.

Comments. We studied several species of these two genera and found that their diagnostic features were the same: antennae, wing venation, body structure and ovipositor shape were all identical. The only differences appear to be those suggested by NOYES & HAYAT (1984) and NOYES (1990). In Epitetracnemus there is a line of silvery setae across the face and the fore wing has a stronger pattern of infuscation. In Adelencyrtus the face lacks a line of silvery setae and the fore wing is generally hyaline or only weakly infuscate. However these characters show some varaibility across these genera. ZHANG & SHI (2010) also stated that these two genera are very close and that further studies were needed to assess the validity of the two genera. For instance Epitetracnemus comis Noyes & Ren, 1987 is extremely close to Adelencyrtus and would run to Adelencyrtus in TRJAPITZIN’ s (1989) key to Palaearctic species. In this species, the line of silver setae across the face is hardly present and therefore we suggest that Epitetracnemus should be treated as a junior synonym of Adelencyrtus . As a result of this synonymy, besides the combinations proposed below, the following new combinations are proposed: Adelencyrtus bandus ( Zhang & Shi, 2010) comb. nov. (from Epitetracnemus ),

A. kosef (Li & Byun, 2002) comb. nov. (from Epitetracnemus ), A. reni ( Zhang & Shi, 2010) comb. nov. (from Epitetracnemus ), A. sexguttatipennis (Girault, 1915) comb. nov. (from Epitetracnemus ), A. shanghaiensis (Si, Li & Li, 2010) comb. nov. (from Epitetracnemus ).
