Remarks. This species was named in honor of Fritz Müller, a German researcher who lived in Santa Catarina, Brazil, and worked from 1876 to 1891 as a traveling naturalist for the Museu Nacional/UFRJ. He wrote nearly 260 scientific articles, including some on Brazilian species of Crustacea, and was a strong defender of the natural selection ideas of Charles Darwin (Souza and Kamensky, 2016). The original spelling of the epithet name mülleri was changed to muelleri due to an improper use of diacritical mark ( Boyko et al., 2023).
