  • 🎰 The BRCs most frequently used for deposits in this group are: CIP: 1; NCIMB: 1.
  • 🧍 According to Shipunov (2011), this name is a hemihomonym. Publication: Shipunov A. The problem of hemihomonyms and the on-line hemihomonyms database (HHDB). Bionomina 2011; 4:65-72.
  • 🧍 Quadricoccus Maszenan et al. 2002 is illegitimate because of precedence of the algal genus Quadricoccus Fott 1948 [Principle 2, Rule 51b(4)].

  • 🧍 The name Quadricoccus Maszenan et al. 2002 is illegitimate because of precedence of the algal genus name, Quadricoccus Fott 1948 [Principle 2, Rule 51b(4)]. Consequently, a new genus designation Quatrionicoccus has been proposed by Tindall and Euzéby 2006. Publication: Tindall BJ, Euzeby JP.
