Leiobracon gen. nov. will run to couplet 10 in the key to world genera by Quicke (1987), where it can be distinguished from Pseudoshirakia as follows (based on female):

10a Metasoma largely smooth and its second suture shallow, smooth ( Figs 1B , 2F ); first metasomal tergite more than 2.6 × longer than wide medially, its lateral areas largely reduced and without crenulations; second metasomal tergite triangular, without triangular basal area ( Fig. 2F )..................................... Leiobracon Long & van Achterberg , gen. nov.

10b Metasoma largely sculptured and its second suture deep, crenulate ( Fig. 4B ); first metasomal tergite less than 2.0 × longer than wide medially and its lateral areas distinct and with crenulations; second metasomal tergite rectangular with triangular basal area ( Fig. 4B ).......................................................... Pseudoshirakia van Achterberg, 1993
