Genus Galiomyza Spencer 
Galiomyza Spencer, 1981: 288. Type of 
genus: Agromyza morio (Brischke) 
(Europe) . 
The leaf miners on Galium known in 
Europe and North America are close to 
but clearly distinct from Liriomyza , 
lacking the stridulating mechanism and 
with the scutellum largely black. 
Their generic position has been 
problematic, but the new genus 
Galiomyza was erected to accommodate 
them by Spencer, 1981. 
A new species feeding as a leaf miner 
on Viola is apparently widespread in 
North America and is described here as 
Galiomyza violivora . It also lacks 
the stridulating mechanism, and with 
no discrete surstylus it cannot be 
included in Liriomyza . The male 
genitalia and epandrium differ 
slightly in form from those of the 
Galium feeders, but it seems
