l 982), and P. brevisetoSus FUI ITA, l 989) resemble the new species in sonae re- Specis, particularly in haVing minute notogastrat fetae, long and barbed sensilli with a more or less swollen apical portion. But the new species, ProtorthiateSDaycinicuS, differs frona any of the species mentioned ab ove in having smooth and relative ly shon interlamellar setae. In addition. P. monodactyluS and P. Seminudus differ frona the new species in the long and distinctly barhed lamellarand rostrat fetae and comparative ly narrow Swollen portion os sensilli. P. Brevi setosus is distinguis habie frona the new species by the s horter and wider sit ape of the notogaster, the relative ly long prodorsum and shori lamellar setae seta las horter than ro). P. graciliS is readi ly distinguis hed frona the new species by the distinctly narrowed shape of the notogaster, the longer prodorsum, distinctlyharbed rostrat, lamellar and interlamellar setae, the prese iace of a longitudinatrici ge extending frona the lamella. and minute ly barbed and strongly swollen head of the sen Sili US.
