and an additional female, all from Sarawak, Malaysia. During my 
study of material in the U.S. National Museum of Natural History, 
Washington [USNM], I located an additional male specimen of K. 
eumenidarum. This specimen [India: Kerala Survey, 12.5 Pechipa- 
rai, 25-27 August 1974] was dissected and re-mounted and is the 
basis for the description of the labrum and male genitalia. In addi- 
tion, the C. F. Baker Collection [USNM] contained a new species of 
Krombeinius from the Philippines, which I describe herein.

length of mesoscutum along midline; OOL: length of ocular-ocellar 
line; PN: length of pronotum along midline; POL: length of poste-

somal tergites 2-8. 
Krombeinius 
Krombeinius Boucek, 1978: 302, Figs. 1,2. 
Type species: Krombeinius eumenidarum Boucek, 1978: 302, Fig. 1. [original 
designation]. 
Diagnosis: 
Hymenoptera: Chalcidoidea: Perilampidae (sensu Graham, 1969). 
Species of Krombeinius can be distinguished from Monacon Water- 
ston, Burksilampus Boucek, Steffanolampus Peck and Perilampus 
Latreille by the narrow postspiracular sclerite, less than one-half the 
width of the adjacent pronotal panel, and from Euperilampus by 
having the marginal vein longer than the postmarginal (Fig. 1). 
All known species are moderately large, 3 to 5 Vi mm long, black 
without metallic reflections and are restricted to the Oriental region. 
There are three species currently placed in Krombeinius: K. eume- 
nidarum Boucek, K. megalaspis (Cameron) and K. saunion, n.sp. 
A revised key to the species of Krombeinius is not presented. The 
key of Boucek (1978) separates K. eumenidarum and K. megalaspis. 
An additional character to separate these two species is the inner 
orbits: costate in K. eumenidarum (Fig. 8), and smooth in K. meg- 
alaspis (Fig. 12). K. saunion is readily distinguished from these two 
species by the prominent spine at the apex of the scutellum (Fig. 
1,15). The apex of the scutellum is truncate in the other two species 
(Figs. 7,1 1).
