Another haplotype (w10) was found to be common to the Iberian peninsula and the Balkans. These three populations with geographic isolation exhibited a near lack of gene flow and spatially correspond to three glacial refugia.<ref name=pilot2010/>

The taxonomic reference ''[[Mammal Species of the World]]'' (3rd edition, 2005) does not recognize ''Canis lupus italicus''; however, [[National Center for Biotechnology Information|NCBI]]/[[Genbank]] publishes research papers under that name.<ref>{{cite web|title=NCBI search Canis lupus italicus|url=https://pubmed.ncbi.nlm.nih.gov/?term=canis+lupus+italicus}}</ref>

{{Further|Iberian wolf}}
The [[Iberian wolf]] was first recognised as a distinct subspecies (''Canis lupus signatus'') in 1907 by zoologist [[Ángel Cabrera (naturalist)|Ángel Cabrera]]. The wolves of the Iberian peninsula have [[Morphology (biology)|morphologically]] distinct features from other [[Eurasian wolf|Eurasian wolves]] and each are considered by their researchers to represent their own subspecies.<ref>{{cite web| url = http://www.signatus.org/docs/situation.pdf| title = The wolf in Spain}}</ref><ref>{{cite journal |doi=10.1111/j.1469-7998.2000.tb00801.x|title=Food habits and livestock depredation of two Iberian wolf packs (Canis lupus signatus) in the north of Portugal|journal=Journal of Zoology|volume=251|issue=#4|pages=457–462|year=2000 |last1=Vos|first1=J.}}</ref>

The Himalayan wolf is distinguished by its [[mitochondrial DNA]], which is basal to all other wolves. The taxonomic name of this wolf is disputed, with the species ''Canis himalayensis'' being proposed based on two limited DNA studies.<ref name=agga2007/><ref name=sharma2004/><ref name=shrotriya2012/> In 2017, a study of [[mitochondrial DNA]], [[X-chromosome]] (maternal lineage) markers and [[Y-chromosome]] (male lineage) markers found that the Himalayan wolf was genetically [[Basal (phylogenetics)|basal]] to the Holarctic grey wolf and has an association with the [[African golden wolf]].<ref name=werhahn2017/>

In 2019, a workshop hosted by the [[IUCN]]/SSC Canid Specialist Group noted that the Himalayan wolf's distribution included the Himalayan range and the Tibetan Plateau. The group recommends that this wolf lineage be known as the "Himalayan wolf" and classified as ''Canis lupus chanco'' until a genetic analysis of the holotypes is available.<ref name=Alvares2019/> In 2020, further research on the Himalayan wolf found that it warranted species-level recognition under the Unified Species Concept, the Differential Fitness Species Concept, and the Biological Species Concept. It was identified as an Evolutionary Significant Unit that warranted assignment onto the [[IUCN Red List]] for its protection.<ref>{{cite journal|doi=10.1111/jbi.13824|title=Himalayan wolf distribution and admixture based on multiple genetic markers|year=2020|last1=Werhahn|first1=Geraldine|last2=Liu|first2=Yanjiang|last3=Meng|first3=Yao|last4=Cheng|first4=Chen|last5=Lu|first5=Zhi|last6=Atzeni|first6=Luciano|last7=Deng|first7=Zhixiong|last8=Kun|first8=Shi|last9=Shao|first9=Xinning|last10=Lu|first10=Qi|last11=Joshi|first11=Jyoti|last12=Man Sherchan|first12=Adarsh|last13=Karmacharya|first13=Dibesh|last14=Kumari Chaudhary|first14=Hemanta|last15=Kusi|first15=Naresh|last16=Weckworth|first16=Byron|last17=Kachel|first17=Shannon|last18=Rosen|first18=Tatjana|last19=Kubanychbekov|first19=Zairbek|last20=Karimov|first20=Khalil|last21=Kaden|first21=Jennifer|last22=Ghazali|first22=Muhammad|last23=MacDonald|first23=David W.|last24=Sillero-Zubiri|first24=Claudio|last25=Senn|first25=Helen|journal=Journal of Biogeography|volume=47|issue=6|pages=1272–1285|doi-access=free|bibcode=2020JBiog..47.1272W }}</ref>

====Indian plains wolf====
{{Further|Indian wolf#Canis indica}}
The [[Indian wolf#Canis indica|Indian plains wolf]] is a proposed clade within the Indian wolf (''Canis lupus pallipes'') that is distinguished by its mitochondrial DNA, which is basal to all other wolves except for the Himalayan wolf. The taxonomic status of this wolf clade is disputed, with the separate species ''Canis indica'' being proposed based on two limited DNA studies.<ref name=agga2007/><ref name=sharma2004/> The proposal has not been endorsed because it relied on a limited number of museum and zoo samples that may not have been representative of the wild population, and a call for further fieldwork has been made.<ref name=shrotriya2012/>

The taxonomic reference ''Mammal Species of the World'' (3rd edition, 2005) does not recognize ''Canis indica''; however, [[National Center for Biotechnology Information|NCBI]]/[[Genbank]] lists it as a new subspecies, ''Canis lupus indica''.<ref>{{cite web|title=Canis lupus indica|url=https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=242524}}</ref>

====Southern Chinese wolf====
In 2017, a comprehensive study found that the gray wolf was present across all of mainland China, both in the past and today. It exists in southern China, which refutes claims made by some researchers in the Western world that the wolf had never existed in southern China.<ref name=wang2017/><ref name=larson2017/> This wolf has not been taxonomically classified.<ref name=smith2008/><ref name=wang2003/>

In 2019, a genomic study on the wolves of China included museum specimens of wolves from southern China that were collected between 1963 and 1988. The wolves in the study formed three clades: northern Asian wolves that included those from northern China and eastern Russia, [[Himalayan wolf|Himalayan wolves]] from the Tibetan Plateau, and a unique population from southern China. One specimen from [[Zhejiang]] Province in eastern China shared gene flow with the wolves from southern China; however, its genome was 12–14 percent admixed with a canid that may be the dhole or an unknown canid that predates the genetic divergence of the [[dhole]]. The wolf population from southern China is believed to still exist in that region.<ref name=Wang2019/>
