Laietani - in the low Llobregat river basin, along a part of the Mediterranean coast roughly in what is today a part of the Barcelona province and Barcelona city. Laieta (Barcino in Roman times and Barcelona in modern times) was their main centre.
Pellendones/Cerindones, in high Duero river course (Numantia) and neighbouring mountains, might also have been related to the Pelendi/Belendi that dwelt in the middle Sigmatis river, today's Leyre (river).
Conii – according to some scholars, Conii and Cynetes were two different peoples or tribes and the names were not two different names of the same people or tribe; in this case, the Conii possibly dwelt along the northern banks of the middle Anas (Guadiana) river, in today's western Extremadura region of Spain, and were a Celtici tribe wrongly confused with the Cynetes of Cyneticum (Algarve) that dwelt from the west banks of the Low Anas (Guadiana) river further to the south (the celticization of the Cynetes by the Celtici confused the distinction between the two peoples or tribes).
Suessetani - Far North Western Aragon and Far South Eastern Navarra (Spain), between the Gallicus (Gállego) and Low Aragon rivers and between the Ebro river and Sierra de Santo Domingo Mountains. Alba (Arba) river basin (a tributary of the Ebro) was in the centre of their territory that also included the Bardenas Reales. Corbio was their capital. They were North of the Celtiberians, South of the Iacetani and the Vascones, West of the Galli (tribe). They were later conquered by the Vascones in the 2nd century BC. that were allies of the Romans. Could have been related to the Suessiones (a tribe of the Belgae).
Volciani – might have been a tribe related to the Volcae and not to the Hispano-Celts/Iberian Celts (i.e. the Celts of the Iberian Peninsula). They have been located north of the Iberus (Ebro) river but not very precisely.
Gauls (Galli) – Some Gaulish tribes might have migrated southwards and crossed the Pyrenees (by the north, the central or the south areas of the mountains) in a second or a third Celtic wave to the Iberian Peninsula. These tribes were different from the Hispano-Celtic/Iberian Celtic tribes.
Galli (tribe) – along Gallicus (Gállego) river banks, see place names (toponyms) like Forum Gallorum, Gallur, a different tribe from the Suessetani; might have been a tribe related to the Galli (Gauls) and not to the Hispano-Celts/Iberian Celts.
Lusitanians (Lusitani/Bellitani) – Portugal south of the Douro River and north of Tagus River, and northwestern Extremadura (Spain). They spoke Lusitanian that is a clearly Indo-European language but the filiation as a Celtic language is not surely proven (although many tribal names and place names, toponyms, are Celtic). Attempts to classify the language have also pointed at an Italic origin. Hence Lusitanian language may have been a Para-Celtic Indo-European branch like Ligurian (i.e. an Indo-European language branch not Celtic but more closely related to Celtic). The Lusitanians have also been identified as being a pre-Celtic Indo-European speaking culture of the Iberian Peninsula closely related to the neighbouring Vettones tribal confederation. However, under their controversial theory of Celtic originating in Iberia, John T Koch and Barry Cunliffe have proposed a para-Celtic identity for the Lusitanian language and culture or that they spoke an archaic Proto-Celtic language and were Proto-Celtic in ethnicity.
