A new genus and two new species of parrot Mallophaga (Phthiraptera) from New Guinea

A new genus, Theresiella, gen. n., and two new species, hitchcocki, sp. n., and gemina, sp. n., are described from Psittacella brehmii (Psittacidae), of New Guinea. This is the first paper in an intended series on the Philopterid Mallophaga found on Psittaciformes. The present paper deals with materials belonging to the CSIRO, Canberra, Australia, sent to me by Dr. Theresa Clay (British Museum, Natural History), whom I thank for the loan. The specimens were collected from parrots of the genus Psittacella. According to Peters (1937, checklist of birds of the world, vol. 3) the genus occurs only in New Guinea and has three species.: brehmii, picta and modesta, each one with several subspecies distributed over the entire island.
