Table I. Comparison of oviposition and pollination, and of pollen collecting 
between Pegoscapus assuetus and P. jimenezi (described in this paper) and P. tonduzi 
and P. estherae (Galil et al. 1973). All these wasps pollinate figs of the monoecious 
section Urostigma. These descriptions are schematic and are only meant to highlight 
obvious similarities and differences. See original descriptions for more details. 
Pegoscapus assuetus and P. jimenezi 
Oviposition and Pollination: Probe synstigma with 
ovipositor — • insert ovipositor down style — oviposit — loosen 
pollen grains in mesothoracic pockets with coxal-femoral rake 
— * collect pollen in arolia from thoracic or coxal pollen 
pockets 1 — wipe pollen from arolia onto hypopygium 2 — drag 
hypopygium over synstigma. 
Pollen Collecting: slit anther with antennal horn — • place 
anterior portion of head in anther — [right arolium scoops 
pollen from anther 3 — right arolium pulled towards ventral 
surface of body, left arolium simultaneously extended ■ left 
arolium scoops pollen from anther, right arolium simultane- 
ously places pollen load on exposed left coxal pocket — ^right 
arolium extended to scoop pollen load from anther, left aro- 
lium simultaneously places pollen load on exposed right coxal 
pocket] — repeat brackets 16-32 (n=7) times — - forecoxae 
rubbed posteriorly over mesosternum, then laterally over 
mesothoracic pollen pockets, transferring most of pollen to 
these pockets. 
Pegoscapus tonduzi and P. estherae 
Oviposition and Pollination: Probe — insert — oviposit 
— loosen pollen — collect pollen into arolia 1 — release pollen 
by rubbing arolia together above (not touching) synstigma 2 . 
Pollen Collecting: slit anther — head in anther — ■ arolia 
alternately lift pollen (up to 40 times) towards ventral surface 
of thorax — some pollen pressed into intersegmental chamber 
by forecoxae — coxae rubbed over mesosternum and pollen 
pockets, filling mesothoracic pockets, repeated several times. 
'It is not known whether the arolia usually collect pollen from the thoracic pockets, 
or from the coxal pockets. My interpretation of P. assuetus and P. jimenezi is that 
pollen is taken directly from the thoracic pockets; Galil et al. (1973) suggest that the 
arolia collect pollen from the coxal pockets in P. tonduzi and P. estherae. 
: This is the clearest difference between the two pairs of species. 
•’Choice of the right foreleg instead of the left is arbitrary, and only for purposes of 
illustration.
