Holotype: Male (ISLA 96886), Brazil, state of Pará, municipality of Aveiro, Paraíso Cave (04 º 04 ’ 31,5 ” S 55 º 27 ’ 31,6 ” W), 05. X. 2020. Paratypes: 1 male (ISLA 96887, in slide), same data as holotype; 1 juvenile (ISLA 96888) same data as holotype; 1 female (ISLA 96889), same data as holotype, 07. X. 2020; 4 males, 4 females (ISLA 96891), same data as holotype, 06. X. 2020; 2 males, 2 females (ISLA 96892), same data as holotype. Etymology. The new species is named after the cave where it was found. The Portuguese word “ Paraíso ” is translated to “ paradise ” in English, and, in Latin, paradisus. Diagnosis. Circoniscus paradisus sp. nov. is characterized by absence of eyes and body pigment; presence of schisma on pereonite 1 in all specimens; antennula with 2 + 9 aesthetascs; pleonites 3 – 5 epimera inner face with continuous ridge; distal margin of male pleopod 1 exopod elongated; and endopod apex curved inward. Description. Maximum body length: male 8.7 mm; female: 9.5 mm. Eyes and body pigments absent. Body convex, endoantennal conglobation (Fig. 2 A) covered by small triangular scale-setae. Noduli lateralis and glandular pores not visible (Fig. 4 E) Cephalon (Figs. 2 B, 4 A) wider than long, frontal shield continuous with pereonite 1, frontal margin broadly rounded. Pereonite 1 epimera (Fig. 5) with schisma in all specimens; pereonites 2 and 3 (Fig. 4 D, E): with ventral lobes; pereonites epimera inner face (Fig. 4 E, F) with continuous ridge. Pleon (Fig. 2 A) outline continuous with pereon, epimera 3 – 5 well developed, telson triangular, wider than long, rounded apex. Telson (Figs. 2 C, 4 G) triangular, anterior margin concave, lateral margins following outline of pleonite 5, distal margin acute. Antennula (Fig. 2 D) 3 - articulated, distal article approximately 4 times longer than second article, conical bearing 9 aesthetascs in 4 rows, plus 2 apical. Antenna (Figs. 2 E, 4 B, C) short and stout, not surpassing pereonite 1 when extended backwards; f lagellum with 2 subequal articles; distal article bearing 2 lateral sets of 2 and 3 aesthetascs; apical organ as long as distal article of flagellum.	en	Ferreira, Júlia Barbosa Galo Giovanna Monticelli Cardoso Rodrigo Lopes (2025): In the depths of the Amazon rainforest: a new troglobitic species of Circoniscus (Isopoda: Scleropactidae) from Brazil.
