Combès (2012) suggests that -toki ~ -tuki ~ -tuke (also present in the ethynonym Gorgotoqui) is likely related to the Bororo animate plural suffix -doge (i.e., used to form plural nouns for ethnic groups). Hence, the name Otuqui (Otuke) was likely etymologically related to the name Gorgotoqui.[2]
Other varieties
Loukotka (1968)
Several attested extinct Bororoan varieties were either dialects of Otuke or closely related:[3]
Mason (1950) says the first four are "separate and very different", but Loukotka (1968) notes that nothing is known of Curave or Curucane (or of Tapii), that only 14 words of Curumina and 19 of Covare have been preserved.[3]

Mason (1950) lists the following varieties of Otuke:[4]
