143B9D3D323FE361B08F43340213CE4E.taxon	etymology	Etymology. The specific epithet is a noun in apposition. In Brazilian folklore, Boitatá (also known as the " fire serpent ") is a mythical creature that protects forests and fields from those who seek to burn or destroy them. In some versions of the legend, it is described as a large, glowing serpent that transforms into a blazing log to punish wrongdoers.	en	Galo, Júlia Barbosa, Cardoso, Giovanna Monticelli, Ferreira, Rodrigo Lopes (2025): Breaking ground below: first troglobitic Circoniscus (Isopoda: Scleropactidae) from Southeastern Brazil.

143B9D3D323FE361B08F43340213CE4E.taxon	description	Description. Male holotype (ISLA 97041). Maximum body lenght: 4.3 mm. Eyes and body pigment absent. Body convex, with endoantennal conglobation capacity (Fig. 1 A), surfacecovered by small triangular scale-setae. Noduli laterales and glandular pores not visible (Fig. 2 F). Cephalon (Figs 1 B, C; 2 A, B) wider than long, frontal shield continuous with pereonite 1, frontal margin broadly rounded with concave sides, lateral lobes absent. Pereonite 1 epimera (Fig. 1 A, D; 2 F) with schisma; pereonites 2 and 3 (Fig. 1 A, D; 2 G) with ventral lobes; pereonites epimera inner face (Fig. 2 G) with continuous ridge. Pleon (Fig. 1 E; 2 H) outline continuous with pereon, epimera 3 – 5 well developed. Pleotelson (Fig. 1 E; 2 H) triangular, broader than long, anterior margin straight, lateral margins not following outline of pleonite 5, distal margin rounded. Antennula (Fig. 1 F) with three articles, distal article approximately five times longer than second article, conical, with seven lateral aesthetascs arranged in three sets. Antenna (Fig. 1 G; 2 C, D) short and stout, not surpassing pereonite 2 when extended backwards; flagellum of two articles, distal article elongated, longer than proximal article, bearing two lateral sets of three aesthetascs each; apical organ longer than distal article of flagellum. Mandibles (Fig. 3 A, B) molar penicil with 6 - 7 branches, left mandible with 2 + 1 penicils and right mandible with 1 + 1 penicils. Maxilliped (Fig. 3 C) basis rectangular, bearing sparse thin setae; palp proximal article with one long seta, medial and distal articles with two tufts of long thin setae; endite subrectangular, medial seta short, not surpassing distal margin, distal margin covered with thin setae, without any seta on outer portion, rostral surface with one short penicil. Maxilla (Fig. 3 D) inner lobe rounded, covered with thick setae, outer lobe approximately three times wider than inner lobe; covered with thin setae. Maxillula (Fig. 3 E) inner endite with two apical penicils, distal margin slightly rectangular; outer endite with 6 + 6 teeth, inner set with five cleft and one simple teeth. Pereopods (1 - 7) gradually increasing in size. Pereopod 1 (Fig. 2 E; 4 A) covered by robust setae, mainly propodus, carpus and merus; propodus and carpus with sparse hand-like setae on distal margin, with antennal grooming brush; dactylus inner claw shorter than outer claw, ungual and dactylar setae long and simple. Uropod (Fig. 2 H; 4 H) protopod flattened and elongated, filling gap between pleonite 5 and pleotelson, surpassing distal margin of telson, and surpassing distal halt of exopod length; exopod inserted on median margin of uropod, endopod twice as long as exopod, inserted proximally to endopod. Male. Pereopod 1 (Fig. 2 E; 4 A) merus, carpus and ischium with short scale fields on sternal margin. Pereopod 7 (Fig. 4 B) ischium elongated; sternal margin concave; carpus slightly longer than merus; triangular lobe on rostral portion of merus absent. Genital papilla (Fig. 4 C) with triangular ventral shield and showing subapical orifices. Pleopod 1 exopod (Fig. 4 C) trapezoidal, distal margin roundedwider than long, bearing two small setae; endopod with tapering apex, bent outwards, inner margin with small setae. Pleopod 2 exopod (Fig. 4 D) subtriangular, distal margin elongated, tapering, outer margin covered by thin setae; endopod flagelliform, slightly longer than exopod. Pleopods 3 – 4 exopods as in Fig. 4 E and F, respectively. Pleopod 5 exopod (Fig. 4 G) subtriangular, apex elongated and slightly acute.	en	Galo, Júlia Barbosa, Cardoso, Giovanna Monticelli, Ferreira, Rodrigo Lopes (2025): Breaking ground below: first troglobitic Circoniscus (Isopoda: Scleropactidae) from Southeastern Brazil.
