Pleon in a continuous line with pereon; pleonite I reduced to sternal part; pleonite II visible dorsally on middle. Mandibles without palp. Pereopod I stocky; propodus 3 × as long as carpus, dactylus reaching distal margin of carpus. Pleopods III–V oval-shaped, biramous, with respiratory function. Uropods shorter than pleotelson apex.</p><p>Etymology</p><p>The name ‘ Kaaetecarcinia ’ is derived from the Brazilian indigenous Tupi-Guarani word ‘KAÃ-ETÉ’, which means ‘native forest’ and is combined with the Greek word ‘carcinia’, meaning ‘shrimp’.</p><p>Remarks</p><p>As highlighted in previous studies, pleon and pleotelson morphology are key features in the taxon phylogeny (Van Lieshout 1983; Messana et al. 2002; Prevorčnik et al. 2012; Tabacaru &amp; Danielopol 1999; Tabacaru &amp; Giurginca 2019, 2021 a, 2021 b). In the newly discovered species, these characteristics are also crucial for defining both family and species levels within the Calabozoidea suborder (Van Lieshout 1983; Messana et al. 2002; Prevorčnik et al. 2012; Tabacaru &amp; Danielopol 1999; Tabacaru and Giurginca 2019, 2021; Cardoso et al. 2025a, 2025b). In the species of Calabozoidae, the pleotelson is notably large, being around 30% of the body length in Calabozoa Van Lieshout, 1983 and Pongycarcinia Messana, Baratti &amp; Benvenuti, 2002, and 20% of the body length in Oiticicarcinia Cardoso, Bento &amp; Ferreira, 2025, Itararecarcinia Kury &amp; Villarreal, 2015, Poicarcinia Cardoso, Bento &amp; Ferreira, 2025, and Kaaetecarcinia gen. nov. Relative to the pleon length, the pleotelson is also longer in Calabozoa and Pongycarcinia, being around 75% of the pleon length, and 50–60% in Oiticicarcinia, Itararecarcinia, Poicarcinia and Kaaetecarcinia gen. nov. (Van Lieshout 1983; Messana et al. 2002; Cardoso et al. 2025a, 2025b).</p><p>Kaaetecarcinia gen. nov. is morphologically similar to Calabozoa due to the reduction of pleonites I and II and the shape of the pleopods. In Calabozoa, pleonites I and II are not visible dorsally, being reduced to the sternal part (Van Lieshout 1983; Tabacaru &amp; Giurginca 2019). In Kaaetecarcinia gen. nov., pleonite I is reduced to the sternal part, while only a small portion of pleonite II is visible dorsally. The pleopods III–V in Kaaetecarcinia gen. nov. have respiratory endopods, and their oval-shaped exopods may serve natatory functions, similar to Calabozoa . This contrasts with the round pleopods in Pongycarcinia, Itararecarcinia, and Poicarcinia, and the subrectangular ones in Oiticicarcinia . As mentioned by Van Lieshout (1983), monomorphic pereopods are only found in Oniscidea, whereas other taxa may exhibit specialization in the first or additional pereopods. In Calabozoidea, the pereopod I differs slightly from the others due to modifications in the carpus and propodus. In Kaaetecarcinia, pereopod I is stocky, with a long dactylus reaching the distal margin of the carpus, resembling a subchelae structure.</p></div>	https://treatment.plazi.org/id/966C87D6FFE3FFBAFD056A19E4C6FEA6	Public Domain	No known copyright restrictions apply.
