Extract

Syphacia (Syphatineria) oceanica sp.nov. is described from the squirrel Sundasciurus steerii juvencus. It is closest to S. transafricana Chabaud & Biocca, 1955, differing from it in having a cephalic vesicle, an isthmus between oesophagus and bulb, and in characteristics of the gubernaculum. Syphacia (Syphacia) critesi sp.nov. is described from S. steerii juvencus and the flying squirrel Hylopetes nigripes. It is closest to S. thompsoni Price, 1928, differing from it in lacking cephalic vesicle, alae, and cervical papillae; in having a long oesophagus and shorter gubernaculum Syphacia (Syphacia) magnispicula sp.nov. is described from H. nigripes and S. steerii juvencus. It is characterized by having a spicule 312–338 μm long, much longer than any species yet reported. Syphacia (Syphacia) coli sp.nov. is described from H. nigripes and the rat Rattus exulans luteiventris. It is closest to S. critesi sp.nov., differing from it in sizes and shapes of oesophagus and gubernaculum, in having lateral alae, and in egg size. Syphacia sp. is reported from Rattus exulans luteiventris; Blattophila sp. is reported from the skunk Mydaus marchei; and Allodapa sp. is reported from Sundasciurus steerii juvencus.

The authors wish to express their appreciation to Dr D. S. Rabor, Silliman University, Dumageute, Negros Oriental, Republic of Philippines, for general support in field activities and for tentative host identifications; Mr Max Thompson, Bishop Museum, Honolulu, for assistance in collection of hosts and Dr David H. Johnson, Research Curator, Division of Mammals, U.S. National Museum Washington, D.C., for final host identifications. Thanks are extended to Dr W. G. Dyer and Dr P. D. Leiby, Minot State College, for technical assistance during the course of this work, and to Dr W. W. Becklund, Beltsville Parasitological Laboratory, for the loan of specimens for comparative purposes. Special thanks are due to Mrs MayBelle Chitwood, whose efforts greatly improved the quality of this work.
