Species composition.
Horton et al. (2025) enumerated 21 species in the genus: M. anoculata Rabindranath, 1983 ; M. bousfieldi Krapp-Schickel & Jarrett, 2000 ; M. danae ( Stimpson, 1853) ; M. denticoxa Ariyama, Kodama & Tomikawa, 2020 ; M. edwardsi Chevreux, 1919 ; M. fusca Spence Bate, 1864 ; M. grossimana ( Montagu, 1808) ; M. hirondellei Chevreux, 1900 ; M. irregularis Myers & Nithyanandan, 2016 ; M. jerrica Krapp-Schickel & Jarrett, 2000 ; M. loveni ( Bruzelius, 1859) ; M. lucinae Krapp-Schickel, 2004 ; M. nelsonae Krapp-Schickel & Jarrett, 2000 ; M. pachytelson G. Karaman & Ruffo, 1971 ; M. sagamiensis Ariyama, 2020 ; M. schieckei G. Karaman & Ruffo, 1971 ; M. similis Stout, 1913 ; M. sodalis G. Karaman & Ruffo, 1971 ; M. spinimana Ren, 2012 ; M. tenera Sars, 1885 ; M. umarae García-Madrigal, 2010 . However, Maera spinimana lacks an important diagnostic feature of the genus: the setose outer margin of the gnathopod 2 dactylus. According to the key to genera in Krapp-Schickel (2008), this species is included in the genus Othomaera Krapp-Schickel, 2000 , and the species name should be changed to Othomaera spinimana comb. nov. In total, the genus Maera is composed of 21 species including the new species, M. guaiao sp. nov.
