The word "Johnittia" is a relatively uncommon name, but its spelling follows typical English phonetic patterns. The first syllable "Jo-" is pronounced like the word "yo" with a "j" sound in front. The "hnit" in the middle sounds like "nit," with the "h" being silent. The final syllable "tia" sounds like "tea-uh." So, the full IPA transcription for "Johnittia" would be /dʒoʊˈnɪt.iə/, with stress on the second syllable.
