Key to subgenera of Eupelmus Dalman

1 Female .............................................................................................. 2

- Male................................................................................................ 5

2(1) Brachypterous........................................................................................ 3

- Macropterous......................................................................................... 4

3(2) Metanotum large, flattened, and more or less concave posterior to scutellar apex; propodeum very strongly transverse medially and with at most a flat, inconspicuously differentiated plical region ( Gibson 1990, figs 18, 20−23); pronotal collar with transverse ridge or crest ( Gibson 1990, fig. 34)....................... E. ( Macroneura ) (see Gibson 1990 for key to species)

- Metanotum transverse with convex dorsellum covering apex of scutellum ( Figs 11, 50); propodeum with a conspicuous V or U-shaped plical depression medially ( Figs 11, 50); pronotal collar without transverse ridge ( Fig. 11)......... E. ( Eupelmus )

4(2) Mesotarsal pegs white to reddish, often difficult to distinguish from tarsomeres (Figs 1−5); mesotibial apical pegs, if apparent, more or less spinelike and same color as tibia; propodeum without distinctly exposed plical depression, the posteriorly protuberant dorsellum essentially contiguous with incised anterior margin of propodeum ( Gibson 1995, figs 181, 240); lateral surface of prepectus bare.................................................................... E. ( Episolindelia )

- Mesotarsal pegs usually black, but at least brown and contrasting distinctly with whitish tarsomeres ( Figs 18, 19, 32, 33); mesotibia sometimes without ( Fig. 18), but usually with row of dark pegs along apical margin ( Figs 19, 32, 33); propodeum with V to U-shaped plical depression exposed posterior to almost transverse posterior margin of dorsellum (Fig. 50); lateral surface of prepectus often with setae (e.g. Figs 42−44)............................................. E. ( Eupelmus )

5(1) Flagellum short-clavate and with apex of pedicel and strongly transverse fl1 yellow (Fig. 6); tegula yellow, contrasting with metallic green mesosoma (Fig. 6); pedicel ventrally without line of long, distally curved setae; head with short, scattered seta above and below malar sulcus......................................................... E. ( Episolindelia ) [part]

- Flagellum variable, often slender to robust-filiform, but if distinctly clavate then pedicel and flagellum dark; tegula usually dark; pedicel ventrally usually with line of long, distally curved setae (Figs 55, 57, 64−66); head usually with one longer seta below malar sulcus near base of mandible and sometimes additional long, curved setae on lower face above malar sulcus (Figs 64, 67−70)........................................................................................... 6

6(5) Head without differentiated long seta below malar sulcus; pedicel ventrally with 2−4 straight setae, but at most only 3 in single line (Fig. 56)......................................................................................... 7

- Head with one seta below malar sulcus obviously longer than other setae (Figs 64, 67−70); pedicel ventrally with longitudinal line of 4–10 quite long setae, and the setae quite obviously curved distally if comparatively few in number (Figs 55, 57, 64−66) (not visible if pedicel appressed to scape)................................................................... 8

7(6) Metacoxa usually extensively yellowish but at least outer surface finely coriaceous, smooth and shiny except for engraved lines; legs often entirely yellowish-orange beyond coxae.................................... E. ( Macroneura ) [part]

- Metacoxa dark with outer surface quite distinctly reticulate; legs with all femora and at least metatibia partly brown (Fig. 7)................................................................................... E. ( Episolindelia ) [part]

8(6) Legs mostly or entirely dark except usually for basal 1−4 tarsomeres and often knees and apices of tibiae very narrowly (Figs 58−61).............................................................................. E. ( Eupelmus ) [part]

- Legs, including sometimes coxae, more extensively light-colored to brown with at least about basal half of tibiae light-colored (Figs 52−54)......................................................................................... 9

9(8) Maxillary and labial palpi and tegula, except sometimes apically, white (Figs 52, 53); head and body distinctly green to blue; flagellum sometimes clavate............................................................. E. ( Eupelmus ) [part]

- Maxillary and labial palpi and tegula brown; head and body often yellowish to brown; flagellum always filiform......... 10

10(9) Mesosoma comparatively short and robust, only about 1.5× as long as wide; metacoxa variably distinctly reticulate-roughened; head and body dark but scape and often legs beyond coxae, or at least tibiae, entirely yellowish (Fig. 54)..................................................................................................... E. ( Eupelmus ) [part]

- Mesosoma more elongate-gracile, at least about 1.7× as long as wide; metacoxa very finely coriaceous; color variable, sometimes almost completely yellowish, but if dark then scape at least dorsally and/or tibiae partly brown… E. ( Macroneura ) [part]
