Genus TYMMOPHORUS Schmiedeknecht 



Tymmophorus Schmiedeknecht, 1913. Opusc. Ichn. 34: 2714. 



Type-species: Tymmophorus lacustris Schmiedeknecht. Monotypic 



This small genus is Holarctic and apparently Neotropic (Mexico). 



fasciventris Dasch. Northern Colo., Alaska, and Yukon. 



Tymmophorus fasciventris Dasch, 1964. Amer. Ent. Inst., Mem. 3: 85. 6, 9. 

 gelidus Dasch. Arctic and subarctic N. W. T.; arctic Greenland.

 gillettii (Davis). Colo. Known only from the holotype. 



Syrphoctonus gillettii Davis, 1895. Amer. Ent. Soc, Trans. 22: 26. 9. 

 obscuripes (Holmgren). Northern Que. w. to n. Yukon and Alaska, s. to n. Colo., n.w. Wyo., and 

 n.e. Calif.; Europe. In Dasch's (1964) revision of the North American Diplazontinae the 

 name graculus (Gravenhorst) is incorrectly applied to this species. Pfankuch (1910) 

 studied the now lost holotype (presumably destroyed in World War II) of Bassus 

 graculus Gravenhorst; he found that B. graculus is a species of Hemitelini and noted 

 that Thomson's (1890) suppression of B. obscuripes Holmgren as a synonym of graculus 

 is incorrect. If specimens in the U. S. Natl. Museum collection are correctly identified, 

 B. graculus Gravenhorst represents an undescribed European genus of Phygadeuontina.
