Key words: New species, Pachyprotasis Hartig, new synonymy, revised key,
Hymenoptera, India.
Twelve species new to the genus Pachyprotasis Hartig are added to Indian fauna.
Described and illustrated as new are: P. maculiventris P. kulwantae, P. cephalopunctata
,
P. politus, P. cuneativentris, P. nigricans, P. salebrousa, P. hargurmeeti, P.foveatus, P.
pleuricingulata, P. punamae and P.frontatus. Seven subspecies viz. P. birmanica tristis
Malaise,P. birmanica ebumipesMalaise,P. opacifronssubpunctata Malaise, P. albicincta
nigripleuris Malaise, P. albicincta albitarsis Malaise, P. albicincta sinobrimanica
Malaise and P. caerulescens kashmirica Malaise have been merged into their respective
