Key to the Neotropical Xanthopimpla (modified from Townes |969)

1 Propodeum with only posterior transverse carina present; metasoma entirely yellow ............................................................................ X. peruana Krieger

– Propodeum with both posterior transverse and anterior transverse carinae present ( Figs 2 , 6 ); metasoma usually with brown or black markings .......... 2

2 Dorsal part of occipital carina lacking; ovipositor sheath usually relatively long, 1.0-1.1 as long as hind tibia*.................................... X. aurita Krieger

– Dorsal part of occipital carina present, from weak to very strong ( Figs 4 , 8 ); ovipositor sheath less than 0.9 as long as hind tibia..................................... 3

3 Dorsal part of occipital carina very strong, forming vertical flange ( Figs 4 , 8 ); mesosternum black ( Figs 1 , 5 ) .................................................................... 4

– Dorsal part of occipital carina weak and low; mesosternum yellow ............. 5

4 Central part of posterior transverse carina horizontal ( Fig. 6 ); propodeum with lateral longitudinal carina present, defining area dentipara ( Fig. 6 ); yellowish species with wide black markings on occipital area ( Fig. 8 ); vertical black stripe on posterior part of mesopleuron ...................... X. jussilai sp.n.

– Central part of posterior transverse carina bowed ( Fig. 2 ); lateral longitudinal carina absent, not defining area dentipara ( Figs 2, 3 ); bright yellow species with small black markings on occipital area, vertical black stripes on anterior and posterior part of mesopleuron ( Fig. 1 )..................... X. amazonica sp.n.

5 Lateral longitudinal carina of propodeum absent, not defining area dentipara; hind femur with a brown stripe on front side.......... X. rhabdomera Townes

– Lateral longitudinal carina of propodeum present, at least partly defining area dentipara; hind femur lacking a brown stripe on front side ......................... 6

6 Area superomedia separated from area dentipara by complete or subcomplete carina; trochanter and nearly always also coxa of hind leg with black markings....................................................................... X. craspedoptera Krieger
