3(1). Mesoscutum predominantly dark brown, either completely or with a small amount of lighter colour near notauli and mediopos- teriorly ( Fig. 16 ). Fore wing with membrane uniformly coloured, without a dark region apically ( Figs 1 , 4 ).............. 4

- Mesoscutum predominantly light coloured (brownish yellow, orange or brownish red). Fore wing with membrane with or with- out a dark region apically ( Figs 2 , 3 )...................................................................... 5

4(3). Frons ( Fig. 5 ), scutellum and hind femur ( Fig. 1 ) predominantly brownish yellow. Propodeum with medial abscissa of anterior transverse carina present or absent................................... E. griffithsorum Gauld ( Costa Rica, Nicaragua)

- Frons ( Fig. 8 ), scutellum, and hind femur ( Fig. 4 ) completely dark brown. Propodeum with medial abscissa of anterior trans- verse carina present......................................................... E. tenebrosus sp. n. ( Mexico)

5(3). Clypeus without a medial tooth on apical edge, but with about six, low crenulations instead........................... 6

- Clypeus with a medial tooth on apical edge or at least slightly protruding medially, but without crenulations ( Figs 5–8 )..... 7

6(5). Fore wing with a well-defined brown spot apically and a second brown region more basally, surrounding veins Rs&M and cu-a......................................................................... E. speciosus Seyrig ( Madagascar)

- Fore wing slightly darkened apically relative to base, but without a well-defined brown spot and lacking any dark area around veins Rs&M and cu-a........................................................ E. formosus Seyrig ( Madagascar)

7(5). Propodeum with the lateral abscissae of the anterior transverse carina (costula) absent or weak (as in Fig. 10 )............. 8

- Propodeum with lateral abscissae of anterior transverse carina present and strong ( Fig. 11 )............................ 9

8(7). Fore wing hyaline basally with a well-defined dark region apically (as in Fig. 3 )........ E. meticulosus Seyrig ( Madagascar)

- Fore wing completely hyaline, without a well-defined dark region apically (as in Fig. 1 ).... E. dolosus Seyrig ( Madagascar)

9(7). Flagellum dark brown to black basally with a well-defined, medial light-coloured band and then dark apically........... 10

- Flagellum red or yellow basally, darkening apically but without a medial, light-coloured band ( Fig. 3 )................. 11

10(9). Fore wing darkened apically and also with two medial infumate bands, one basal to the stigma (around vein Rs&M) and one apical to it including the vein 2rs-m (intercubitus of areolet)........................ E. scrupulosus Seyrig ( Madagascar)

- Fore wing with a dark spot apically, but lacking any darkened regions basally or medially (as in Fig. 3 ).......................................................................................... E. calamitosus Seyrig ( Madagascar)

11(9). Tergites 4 to 7 dark brown. Fore wing only vaguely more infumate apically than basally (without a clearly defined dark spot)........................................................................... E. dubiosus Seyrig ( Madagascar)

- All metasomal tergites orange (laterotergites 3 and 4 may be brown). Fore wing with a clearly defined dark spot apically ( Fig. 3 )................................................................................................. 12

12(11). Metasomal laterotergites 3 and 4 brown ( Fig. 3 ). Ovipositor strongly upcurved and much shorter than length of metasoma.............................................................................. E. luteus sp. n. ( Honduras)

- Metasomal laterotergites 3 and 4 orange. Ovipositor straight and about two times as long as metasoma............................................................................................ E. maculosus Seyrig ( Madagascar)
