Key to the known species of Percnobracon

1 Mesoscutum rounded anteriorly in lateral view ...... P. stenopterus Kieffer & Jörgensen

1’ Mesoscutum strongly angled anteriorly in lateral view ( Figs. 4 , 9 , 13 )........................ 2

2 Head 0.65 to 0.70 times as long as high ( Fig. 13 ); mesoscutum mostly coriareous; metasomal tergum I triangular in lateral view, with smooth anterior area almost half as long as the segment and narrowing apicaly ( Fig. 12 ) ................................................... 3

2’ Head 0.70 to 0.85 times as long as high ( Figs. 4 , 9 ), usually length/height 0.75 or more; mesoscutum coarsely coriareous to rugulose; tergum I not triangular in lateral view, smooth area distinctly shorter than half the length of the segment and not narrowing apically ( Figs. 3 , 8 ) ........................................................................................... 4

3 Ovipositor sheaths about 1.2 times the length of metasoma ..... P. secundus Muesebeck

3’ Ovipositor sheaths 0.40 to 0.60 times the length of metasoma ( Fig. 13 )........................ ............................................................................................................... P. witru sp. nov.

4 Mesoscutum 0.70 to 0.80 times as long as wide( Fig. 7 ); propodeum rugose medially ( Fig. 8 ); forewing vein 2RS at most 0.30 times as long as (RS+M)b ( Fig. 5 ), usually much shorter; associated with eurytomid galls ................................. P. rugosus sp. nov.

4’ Mesoscutum 0.65 to 0.70 times as long as wide( Fig. 2 ); propodeum smooth medially only with a few poorly indicated carinae ( Fig. 3 ); forewing vein 2RS 0.40 to 0.50 times as long as (RS+M)b ( Fig. 1 ); associated with cecidomyiid galls. ......................... ..................................................................................................... P. pampeanus sp. nov.
