 ENALODROMA Thomson, 1859, p. 39. [Subgenus of Ischnopoda.] 

 Genotype : Enalodroma fucicola Thomson. 



Fixed by: Thomson, 1859, p. 39, by original designation and monotypy. 

 Later citations: E. fucicola Thomson, by Fauvel, 1876a, p. 132, 266. E. 



hepatica (Erichson), by Fenyes, 1918, p. 22; by Scheerpeltz, 1929b, p. 



239 ; 1934, p. 1603 ; by Tottenham, 1949b, p. 392 ; not originally included. 

 Discussion: The designation of hepatica can be accepted only through the 



subjective synonymy of hepatica and fucicola. Tottenham (1949b, p. 



393) states that Thomson In 1859 included only an undescribed species 



under this name. However, Thomson actually gave the following : "Enal- 

 odroma. Typus B. fucicola n. sp." as the line over the description. Under 



the precedent established in Opinion 43, this description validates both 



generic and specific names.
