Holotype: (female) Argentina (Salta: Urundel, January 31, 
1950, R. Golbach) . (Tucuman). 
Female: Color: antenna black with a white dorsal band that 
begins at the apex of 5th flagellomere and extends to the base of 
12th; flagellomeres 6-10 each also with a little white near the base 
ventrally; apex of pedicel and base of first flagellomere tinged with 
dark brown, and apical 1/3 of flagellum ventrally stained with gray. 
Head and mesosoma black with the following white markings: 
pair of large dorso-lateral blotches on clypeus; central blotch on 
front; wide orbital band, which below extends broadly across malar 
space but which above is interrupted over about the upper 1/3 of 
the external orbit; broad band on all but hind angle of anterior mar- 
gin of pronotum; large blotch medially on dorso-lateral margin of 
pronotum ; tegulae ; pair of longitudinal lines on mesoscutum ; scutel- 
lum, except near apex; large blotch on subalarum; large, irregular, 
oblique blotch that covers much of lower 2/3 of mesopleuron be- 
tween the prepectal carina and the lower hind corner; upper 2/3 of 
hind margin of mesopleuron; a pair of extensive, very much brown- 
tinged blotches on mesosternum near bases of coxae; large blotch 
covering most of upper division of metapleuron; oval medio-basal 
blotch on propodeum ; and a pair of very large and irregular postero- 
lateral areas situated partly on propodeum and partly on dorsal re- 
gion of lower division of metapleuron ; some cephalic and mesosomatic
