punctate-reticulate, punctures coalesced to form weak irregular 
transverse costulae medially; midlobe of mesoscutum and scutellum 
weakly punctate, becoming punctate-reticulate along notauli; side- 
lobe of mesoscutum smooth along notauli, laterally punctate- 
reticulate; notauli distinct; scutellum in lateral view tapering abrupt- 
ly towards apex (Fig. I; cf. Figs. 1,2 in Boucek 1978); underside of 
scutellum mostly coriarious, with shallow convergent grooves; 
propodeum vertical, medially about twice as long as metanotum, 
with weak median ridge, submedian areas with transverse costulae, 
callus reticulate-rugose; width of postspiracular sclerite 0.44 width 
of adjacent pronotal collar, with about 10 foveae; axilla reticulate 
above, costate below; axillula smooth. Forewing: submarginakmar- 
ginakpostmarginakstigmal veins as 64:17:12:4; stigmal vein making 
a right angle (90 degrees) with marginal vein. 
Metasoma: T2 smoothly concave with weak coriarious sculpture; 
T2 with sparse setae, without punctures, border between T2 and T3 
indicated by a suture, laterotergite glabrous; T3 massive and con- 
vex, about twice length of T2 along midline, length about equal to 
maximum width (22 versus 25), evenly covered with long setae 
except along T2 border and along margins of tergite, without 
punctures. 
Male: Unknown. 
Discussion: 
Kronibeinius saunion is more closely related to K. eumenidarum 
than to K. megalaspis. Synapomorphies of these two species are: the 
stigmal vein making a right angle with the marginal vein (oblique in 
K. megalaspis and outgroup: Euperilampus and Perilampus ); cly- 
peal-supraclypeal margin weak or indistinct (separated by distinct 
suture in K. megalaspis and outgroup: Euperilampus and Perilam- 
pus ); lateral pronotal collar suggesting bumpy shoulders (regularly 
convex in K. megalaspis and outgroup: Euperilampus and Perilam- 
pus ); and postspiracular sclerite with many foveae (a single fovea is 
found in K. megalaspis, and in the ancestral species groups of Eupe- 
rilampus, Darling 1983). Considering Euperilampus as the out- 
group, the following similarities of K. eumenidarum and K. saunion 
are regarded as plesiomorphic: propodeum medially about twice as 
long as metanotum (equal to metanotum in K. megalaspis; autapo- 
morphy); scutellum, in lateral view, not strongly convex, tapering 
gradually towards the apex (highly convex in K. megalaspis, Boucek 
1978: Fig. 2; autapomorphy).
