What is "celtici"

The Celtici (in Portuguese, Spanish, and Galician languages, Célticos) were a Celtic tribe or group of tribes of the Iberian peninsula, inhabiting three definite areas: in what today are the regions of Alentejo and the Algarve in Portugal; in the Province of Badajoz and north of Province of Huelva in Spain, in the ancient Baeturia; and along the coastal areas of Galicia. Classical authors give various accounts of the Celtici's relationships with the Gallaeci, Celtiberians and Turdetani.
