B5213824FFEBFFAEFE36FDD6C7730B1A.taxon	etymology	Etymology The term “ Oiticica ” derives from the Brazilian native tree belonging to the genus Licania (Magnoliophyta), frequently found in the Caatinga biome and often growing near cave entrances in the region where the species was discovered. Its name originates from the Indigenous Tupi-Guarani language and is combined with the Greek word “ carcinia ”, meaning small shrimp. Gender feminine.	en	Cardoso, Giovanna Monticelli, Bento, Diego de Medeiros, Ferreira, Rodrigo Lopes (2025): Remnants of an ancient world: three new genera and three new species of Calabozoidea isopods from Brazilian semi-arid caves (Crustacea: Isopoda).

B5213824FFEBFFAEFE36FDD6C7730B1A.taxon	discussion	Taxonomic remarks In the Calabozoidea, pleon and respective pleopods morphology holds significance in the group’s phylogeny (Van Lieshout 1983; Messana et al. 2002; Prevorčnik et al. 2012; Tabacaru and Danielopol 1999; Tabacaru and Giurginca 2019, 2021). However, as new species continue to be discovered, pleon morphology emerges as a crucial character in defining both family and species levels. The newly proposed genus, Oiticicarcinia n. gen., displays notable features such as the reduction of pleonites I and II, well-developed pleopods III – V, and a pleotelson shape akin to other members of Calabozoidae, distinguishing it from Brasileirinidae. Oiticicarcinia n. gen. displays a wider head shield in relation to pleotelson width, while in the former genera it is slender compared to the pleotelson. The pleotelson is relatively short, making up approximately 25 % of the body length and 60 % of the pleon length. In contrast, in both Pongycarcinia and Calabozoa the head shield is slender than the pleotelson and the pleotelson accounts for about 30 % of the body length and 75 % of the pleon length. As a member of Calabozoidae, Oiticicarcinia n. gen. presents the pleopods I and II in both males and females. Until now, the genital papilla was known to have one sole genital apophysis in all three known species of Calabozoidea, while in Oiticicarcinia n. gen. it is bilobed, a novelty for the taxon, but a common feature of variation among isopod species (Wilson 1991). The subrectangular shape of the pleopods III – V exopods differs from those of Pongycarcinia and Calabozoa, which are oval with plumose setae along the margins.	en	Cardoso, Giovanna Monticelli, Bento, Diego de Medeiros, Ferreira, Rodrigo Lopes (2025): Remnants of an ancient world: three new genera and three new species of Calabozoidea isopods from Brazilian semi-arid caves (Crustacea: Isopoda).

B5213824FFE0FFA2FDD5FEBAC7410F18.taxon	materials_examined	Type species: Itararecarcinia yapyra n. sp. Diagnosis Head shield trapezoidal, wider than long, slender than pleotelson. Pleon length about 40 % of body length; pleonites I and II reduced but dorsally visible, not covered by pereonite VII, forming a gap between pereon and pleon. Pleotelson about 25 % of body length and 60 % of pleon length. Genital papilla bilobed. Pleopods III – V expanded, round shaped with two plumose setae proximally, on medial margin. Etymology The name Itararecarcinia is derived from the Indigenous Tupi-Guarani language. “ Itãrere ” means water that originates in stone and flows down a rock. This is in reference to the resurgence where the species were discovered. Additionally, the name incorporates the Greek word “ carcinia ” meaning small shrimp. Gender feminine. Taxonomic remarks As Oiticicarcinia n. gen., Itararecarcinia n. gen. is placed in the family Calabozoidae. Itararecarcinia n. gen. differs from Oiticicarcinia n. gen. by the body shape, with the head shield narrower than the pleotelson (versus wider than the pleotelson); the pleonites I and II not covered by pereonite VII with pereon and pleon line not continuous (versus covered by pereonite VII with a continuous line between pereon and pleon). Itararecarcinia n. gen. and Oiticicarcinia n. gen. are similar in the shape of the genital papilla that is bilobed. Itararecarcinia n. gen. is similar to Pongycarcinia and Calabozoa in the head shield shape that is narrower than the pleotelson; but also differs in body shape that is also continuous in Pongycarcinia and Calabozoa. Moreover, the round shape of pleopods III – V in Itararecarcinia n. gen. resembles Pongycarcinia, contrasting with the oval shape observed in Calabozoa and the subrectangular shape of Oiticicarcinia n. gen.	en	Cardoso, Giovanna Monticelli, Bento, Diego de Medeiros, Ferreira, Rodrigo Lopes (2025): Remnants of an ancient world: three new genera and three new species of Calabozoidea isopods from Brazilian semi-arid caves (Crustacea: Isopoda).

B5213824FFE7FFBAFE2AFCE8C5A20AC4.taxon	discussion	Taxonomic remarks Poicarcinia n. gen. can be distinguished by the subquadrangular shape of the head shield, contrasting with the trapezoidal shape found in other genera. The head is slender than the pleotelson, a feature shared with Pongycarcinia, Calabozoa, and Itararecarcinia n. gen. The pleon exhibits reduced pleonites I and II, but they are not covered by pereonite VII as in Oiticicarcinia n. gen., and the pleonite II is well developed, in similar length as pleonite III. The body outline is not continuous, similar to Itararecarcinia n. gen. The pleotelson size is similar to the pattern observed in Oiticicarcinia n. gen. and Itararecarcinia n. gen., being shorter relative to body length, comprising approximately 20 % of body length and 60 % of pleon length. The shape of pleopods III – V is round, resembling that of Pongycarcinia and Itararecarcinia n. gen., as opposed to the oval shape observed in Calabozoa and Oiticicarcinia n. gen.	en	Cardoso, Giovanna Monticelli, Bento, Diego de Medeiros, Ferreira, Rodrigo Lopes (2025): Remnants of an ancient world: three new genera and three new species of Calabozoidea isopods from Brazilian semi-arid caves (Crustacea: Isopoda).

Pleotelson (Figures 11 A, 10 E, F) about 20 % of body length, and 60 % of pleon length, width about 60 % of pereonite VII, as wide as long, with four setae medially on dorsal surface, and five setae on lateral margin, apex convex with six setae, two of them almost as long as pleotelson. Antennula (Figure 11 B) as long as peduncle of antenna, flagellum of one article with one aesthetasc, longer than flagellum. Antenna (Figure 11 B) short, about 40 % of body length, reaching pereonite III, flagellum with nine articles. Left mandible (Figure 11 D) incisor with four teeth; right mandible (Figure 11 E) incisor with three teeth; lacinia mobilis with denticulate apex. Maxillula (Figure 5 F) lateral lobe with four robust simple setae, four robust serrate setae and one bifid seta medially, mesial lobe with two robust pappose setae and one simple seta. Maxilla (Figure 5 G) lateral and medial lobe with nine serrate setae each; mesial lobe with three robust setae and four plumose setae. Maxilliped (Figure 5 H) endite proximal lobe with six pappose setae apically, distal lobe with two robust pappose setae and four slender pappose setae; palp of five articles, first article fused with maxilliped body, articles with long simple setae, article 5 smallest, with tuft of distal setae. Pereopod I (Figures 12 A, 110 G) ambulatory, carpus half of propodus length, propodus medial margin with three serrate setae, dactylus as long as propodus, unguis half of dactylus length; propodus and unguis medial margin with scales. Pereopod II (Figure 12 B) carpus as long as propodus, dactylus shorter than propodus. Pereopods III – VII progressively long. Pereopod VII (Figure 12 C) 1.6 times longer than pereopod I, propodus longer than carpus, unguis half dactylus length. Uropods (Figures 10 F, 11 A) reach pleotelson apex, uniramous, styliform, about 30 % of pleotelson length. Mature male. Genital papilla (Figure 12 D, F) bilobed wide base with acute, tapering apex. Pleopod I (Figure 12 D, F) stout, longer than wide, distal part wide with apical point. Pleopod II (Figure 12 E) protopodite trapezoidal, endopodite simple and slender, longer than exopodite; exopodite ovoid with two plumose setae distally. Pleopods III – IV (Figure 12 G, F) exopods ovoid with two plumose setae distally, similar in shape; pleopod IV largest. Female (Figure 12 H). Pleopod I inner ramus longer than wide, apex with two plumose setae. Pleopod II protopodite trapezoidal, inner ramus article with one plumose seta apically, outer ramus oval shaped with two plumose setae distally, smaller than pleopod III. Pleopods III – IV exopods ovoid with two plumose setae distally, in similar shape to holotype.	en	Cardoso, Giovanna Monticelli, Bento, Diego de Medeiros, Ferreira, Rodrigo Lopes (2025): Remnants of an ancient world: three new genera and three new species of Calabozoidea isopods from Brazilian semi-arid caves (Crustacea: Isopoda).
