Editing Leopard frog (section)

== New species ==
Several leopard frog species look very similar to each other, and even within a population there is a lot of variation. Some populations may actually be [[Species complex|cryptic species complexes]]. 

In March 2012, it was announced that DNA testing had confirmed that a new species of leopard frog had been found whose habitat was centered near New York's [[Yankee Stadium]]<ref>{{cite web|url=http://newswatch.nationalgeographic.com/2012/03/16/new-frog-discovered-in-nyc-freshwater-species-of-the-week |archive-url=https://web.archive.org/web/20120320031512/http://newswatch.nationalgeographic.com/2012/03/16/new-frog-discovered-in-nyc-freshwater-species-of-the-week/ |url-status=dead |archive-date=March 20, 2012 |title=New Frog Discovered in NYC: Freshwater Species of the Week – News Watch |publisher=Newswatch.nationalgeographic.com |date=2012-03-16 |accessdate=2012-07-09}}</ref> and included northern [[New Jersey]], southeastern [[New York (state)|New York]], and [[Staten Island]]; the new species was first distinguished by its short, repetitive [[Frog#Call|croak]], distinct from the "long snore" or "rapid chuckle" of other leopard frog species in that area (''[[Lithobates pipiens|L. pipiens]]'' and ''[[Lithobates sphenocephalus|L. sphenocephalus]]''). This distinct species has been identified as far south as southeastern Virginia and northeastern North Carolina.<ref>{{cite web| url= https://www.sciencedaily.com/releases/2012/03/120314124016.htm | title= Hiding in Plain Sight, a New Frog Species With a 'Weird' Croak Is Identified in New York City | date= March 14, 2012 | publisher= [[ScienceDaily]] | accessdate=2012-03-15}}</ref><ref>{{cite journal|title=A new species of leopard frog (Anura: Ranidae) from the urban northeastern US|year=2012|doi=10.1016/j.ympev.2012.01.021|pmc=4135705|last1=Newman|first1=Catherine E.|last2=Feinberg|first2=Jeremy A.|last3=Rissler|first3=Leslie J.|last4=Burger|first4=Joanna|last5=Shaffer|first5=H.
