description: Key to genera of the genera of Microgastrinae in Reunion
1 Fore wing with areolet closed (r–m present though sometimes incomplete or hardly pigmented) (Figs 9 c, 11c, 16b)........ 2
– Fore wing with areolet open (r–m totally absent) (Figs 5 b, 6c, 14b, 20d).......................................... 4
2(1) Propodeum with a distinct areola, basally bisected by an incomplete median longitudinal carina (Fig. 11 d).................................................................................................. Dodogaster gen. nov.
– Propodeum without a distinct areola, with a more or less complete median longitudinal carina........................ 3
3(2) Tergum 1 with a long and narrow basal mid-longitudinal groove.............................. Diolcogaster Ashmead
– Tergum 1 without such a long mid-basal groove............................................... Microplitis Förster
4(1) Propodeum with a distinct areola, at least apically and laterally defined, usually with distinct costulae and often basally closed (Figs 4 c, 4e, 5c–d, 5h, 6b, 6e, 12b); a longitudinal median carina may be present as a basal petiole of a complete areola....... 5
– Propodeum without a distinct areola, at most with a small apical fork, often with a median longitudinal carina (Figs 5 f, 7b, 11d, 15b, 15d, 19b)........................................................................................ 8
5(4) Sclerotized part of metasomal terga 1–2 very wide, membranous lateroterga not visible in dorsal view (Fig. 14 d)................................................................................................... Exoryza Mason
– Sclerotized part of at least tergum 1 narrower, membranous lateroterga visible in dorsal view (Figs 4 e, 5d, 6e, 12b, 12d, 13b,18b, 18d)......................................................................................... 6
6(5) Vannal lobe of hind wing straight to distinctly concave in its apical half, the margin irregularly setose (Fig. 2 a–b)..................................................................................... Apanteles Förster (most species)
– Vannal lobe of hind wing regularly convex and setose (Fig. 2 c)................................................. 7
(nb: some confusion is likely to occur between Apanteles and Dolichogenidea which are large and closely related genera. Readers should consider both entries of this couplet for borderline species).
7(6) Hypopygium folded, medially desclerotized into expandable pleats (as in Fig. 3); ovipositor usually long (OT i usually> 0.5), sheath setose on its entire length....................................................... Dolichogenidea Viereck
– Hypopygium evenly sclerotised, though somewhat mid-longitudinally translucent, but without median expandable pleats; ovipositor short, (OT i <0.5), sheath setose at most on its apical half.............................. Parapanteles Ashmead
8(4) Propodeum polished with areola reduced to a small apical fork (Fig. 5 f); ovipositor sheath about as long as half hind femur; small species (B <2mm)................................................... Apanteles Förster (A. bordagei Giard)
– Propodeum different; ovipositor size variable; body size variable but almost always more than 2 mm ................... 9
9(8) Tergum 1 long and narrow, more than 4x longer than wide, with a long basal mid-longitudinal groove (Fig. 20 c); propodeum with three carina diverging from metasomal foramen (Fig. 20 f)...................................... Wilkinsonellus
– Tergum 1 without such a long mid-basal groove, at most with a wide basal depression shorter than half length of tergum; propodeum different.................................................................................. 10
10(9) Propodeum rugose-reticulate (Fig. 7 b), most often with a mid-longitudinal carina; median tergum 2 strongly sculptured (Figs 7 c, 7e, 8f)........................................................................................... 11
– Propodeum most often smooth to moderately punctate (Figs 15 b, 15, 19b), tergum 2 at most weakly sculptured......... 12
11(10) Tergum 2 with a distinct median area enclosed by parallel crenulate grooves (Figs 17 b, 17d).............. Nyereria Mason
– Tergum 2 without distinct median area...................................................... Cotesia Cameron
12(10) Tergum 2 with a median raised area, the area rectangular, longer than wide (Figs 10 b, 10d)............... Distatrix Mason
– Tergum 2 without differentiated median area.............................................................. 13
13(12) Tergum 1 with lateral margins sub-parallel, apically constricted, with a large basal depression; antenna of female short and stout, not reaching beyond propodeum and without median false subdivision of flagellomeres.......... Venanides Mason
– Tergum 1 strongly and regularly narrowed toward apex, without basal depression (Figs 15 b, 15d, 15f, 15i); antenna of female longer, flagellomeres with a median false subdivision..................................... Glyptapanteles Ashmead
