(Life: Kingdom: Metazoa (animals); Phylum: Arthropoda; Class: Hexapoda; Order: Hymenoptera;  Superfamily: Platygastroidea; Family: Platygastridae)

ClassificationIdentification keys


1. Wings absent (A); T1 fused with T2 and S1 fused with S2, with no evident sulcus (A, B); frons with a transverse furrow above torulus Parabaeus

Wings fully developed (a) extending to at least T2 (b); T1 separated from T2 and S1 from S2 by a sulcus (b), sulcus sometimes partly obscured by dense pilosity (b); frons above torulus without transverse furrow 2
 


2. Spur of fore tibia combed (pts) (Isolia species-group) 3

Spur of fore tibia without comb 6
 


3. Pronotum with medial longitudinal sulcus (pms) (A); sternite 2 with long setae (B) Sceliotrachelus



Pronotum without medial sulcus (a); S2 glabrous (b) 4
 


4. Fore wings and microtrichia distinctly bicolored, giving the appearance of patches or stripes Pulchrisolia

Fore wings and microtrichia not bicolored 5
 


5. Fore wing with tubular submarginal vein (A); admedian depressions (adm) present, may be weak (A); transepisternal line present (tel) (B) ...Afrisolia

Fore wing without veins (a); admedian depressions absent (a); transepisternal line absent (b) Isolia
 


6. Fore wing with rudimentary submarginal vein, only sclerotized for about half its length (A); OOL usually subequal to or longer than LOL (B); body usually short and squat Amitus

Fore wing with submarginal vein fully sclerotized, ending in knob (a, b); OOL always distinctly shorter than LOL; body usually elongate, spindle-like 7
 


7. Propodeum medially with single keel (A); metasomal depression not visible; notauli absent (A); scutoscutellar sulcus foveolate (A); anterior T2 with a transverse line of foveae; in females, ventral A8A9 projecting distally; male antenna with long setae; submarginal vein of fore wing distinctly surpassing basal 0.33 of wing (B) Allotropa

Propodeum with H-shaped foamy structure (a); metasomal depression delimited by lateral propodeal carinae; notauli usually abbreviated, triangular (a), absent in a few species; scutoscutellar sulcus simple (a); anterior T2 with two pits, without a line of foveae; antennae variable, but not as above; submarginal vein of fore wing reaching at most to basal 0.33 of wing (b) Fidiobia
