AUSTRALASIAN STILT-LEGGED FLIES (DIPTERA: TYLI- 

 DAE) IN THE UNITED STATES NATIONAL MUSEUM 



By George C. Steyskal 



Collections made during recent years by members of the armed 

 forces in the course of malaria-control work and similar activities have 

 added materially to our knowledge concerning the flies of the family 

 Tylidae in areas not covered in Hennig's recent (1935-1936) mono- 

 graph. This and other material in the United States National 

 Museum were made available to me through the kindness of the au- 

 thorities of the Smithsonian Institution, and study has led to the 

 following results : 



Eleven new forms are described, for one of which a new genus is 

 erected. The genus Miinomyrmecia is transferred from the sub- 

 family Trepidariinae to the Taeniapterinae, and descriptive notes are 

 given. Examination of material determined as Euryhata hexapla has 

 revealed a compact group of species around that form and the fact 

 that other species placed in the genus are abundantly distinct. A new 

 genus, based upon the second species referred to Euryhata^ E. 

 semilauta Osten-Sacken, has been set up for the latter group. Suffi- 

 cient material was examined to make possible a preliminary study of 

 the subspecies of Mimegralla albiinana, a "Formcnkreis" widespread 

 in the East and Oceania. 



Geographical spellings are taken from maps of the National Geo- 

 graphic Society, especially those of the Pacific Ocean (December 

 1936) and southeast Asia (October 1944), except that Japanese forms 

 of names for islands formerly vmder Japanese mandate arc not used.
