Recent taxonomic revision of several North American species

Recent genetic work has distinguished a number of species first considered to be holarctic (present across the northern parts of the world) to be endemic to North America, and these new species have been named:

Lasius americanus, formerly Lasius alienus
Lasius brevicornis, formerly Lasius flavus (still extremely easy to confuse from our other endemic species, Lasius nearcticus)
Lasius aphidicolus, formerly Lasius umbratus

formica subaenescens, formerly Formica fusca (on the west coast, likely throughout the continent. F. subaenescens is not a new name, but the distinction is important.)

Leptothorax canadensis, formerly Leptothorax muscorum (this may be split again into two more species)

ok so basically what i get from this is species that we used to think lived in Europe and america like lasius umbratus are now separated? so now the american lasius umbratus in now called lasius aphidicous? am i right or wrong
keeper of
3 tetremorium queens
2 C. pennsylvanicus
1 C novaeboracensis
1 tapinoma sessile colony
!!And A CREMATOGASTER QUEEN!!

Correct! The taxa in Eurasia are unchanged.

it makes sense because the species here have probably been here long enough for subtle changes to happen.

also Why Lasius aphidicolus? it's so much harder to say than Lasius umbratus

I’m assuming it’s called aphidicolus because the root word is aphid and the species farms aphids. But correct me if I’m wrong.
An ants' strength can be rivaled by few animals compared to relative body size.

i know that it probably serves a purpose i don't know what but that is a good guess. it's just so hard to remember and say.

Aphidicolus translates to "cultivates aphids".

It's common to recycle a taxon that has previously fallen out of use, especially when it is so blandly descriptive.
