0F2F87973A7C9356FF4B203E2D34F8CF.taxon	etymology	Etymology. The epithet is an adjective, and is a tribute to the capital of the state of Rio de Janeiro, the wonderful city. “ Carioca ” comes from two Tupi words: kara'iwa (white man) and oka (house), which together mean “ house of the white man ”. The local indigenous people used the name after the foundation of Rio de Janeiro to refer to the inhabitants of the city.	en	Calvanese, Victor C., Brescovit, Antonio D.

0F2F87973A7C9356FF4B203E2D34F8CF.taxon	diagnosis	Diagnosis. Mecophilus carioca n. sp. resemble M. tupiniquim by the position of the forcipular denticle of tarsungulum, close to the basal margin of the structure (Fig. 4 C) (in M. neotropicus the denticle is positioned in the middle of the article) and subrectangular cephalic plate (Fig. 1 B) (trapezoidal in M. neotropicus). Mecophilus carioca n. sp. differs from M. tupiniquim by the smaller length of the tarsungulum denticle (Fig. 4 C); distal denticle of trochanteroprefemur and denticle of femur are positioned not close to each other (Figs 1 C, 4 B) (close together in M. tupiniquim); and the ultimate legs in females without terminal claw (Figs 1 A, F, 6 A – B) (with a well developed terminal claw in M. tupiniquim).	en	Calvanese, Victor C., Brescovit, Antonio D.

Cephalic plate: longer than wide, 0.3 long and 0.2 wide (length / width ratio 1.5), with sparse setae. General morphology as in Fig. 1 B. Antennae: left antenna 0.52 long (ca. 1.75 times as long as the cephalic plate); length / width ratio of articles II−XIII 0.3 – 0.95; length / width ratio of last article 1.9. Last article with 6 dorsal and 4 ventral claviform specialized setae. Morphology and chaetotaxy as in Figs 1 A – C, 2 A – C. Clypeus: 1 + 1 lateral setae; 1 + 1 post-antennal setae; 3 + 3 subclypeal setae (Fig. 2 D). Mandible: pectinate lamellae with ca. 20 elongated hyaline denticles (Fig. 3 B). First maxillae: left telopodite, length 0.016, width 0.018; distal article with 2 apical and 1 subapical sensilla; each medial projection of coxosternite with 3 subapical sensilla (Fig. 3 A – B). Second maxillae: coxosternite rectangular, concave in the middle of posterior margin (ca. 0.3 times as long as the lateral margins), length / width ratio 0.6; left telopodite, length 0.018 (1.1 times as long as the telopodite of first maxillae), maximum width (basal margin) 0.01; both telopodites with 2 little lateral sensilla on article 1, and 1 short apical and 2 most basal setae on article 3 (Fig. 3 A – D). Forcipular segment: tergite trapezoidal, length 0.14 (0.45 times as long as the cephalic plate), width 0.23 (length / width ratio 0.6), with one row of 6 setae and short sparse setae; pretergite length 0.066 (0.22 times as long as the cephalic plate), width 0.10 (length / width ratio 0.66); coxosternite length 0.3, width 0.24 (length / width ratio 1.25); telopodite length 0.25, reaching but not surpassing the anterior margin of the cephalic plate, trochanteropr efemur + femur with 2 well developed denticles, tibia with 1 small denticle; denticle of trochanteroprefemur with 1 short apical seta, denticle corresponding to the vestigial femur with bilobed shape and with 2 subapical and one apical setae, denticle of tibia with 1 apical and 2 subapical setae; tarsungulum 0.6 times as long as trochanteroprefe mur + femur, with a reduced denticle. Right calyx inside the leg-bearing segment 9, left calyx inside the leg-bearing segment 10 (Figs 1 C, 4 A – D). Tergites from the first to penultimate leg-bearing segment: rectangular metatergites, with two rows of 8 setae and short sparse setae; metatergite 15 length 0.095, width 0.23 (length / width ratio 0.4); pretergite 15 with 0.4 times as long as previous metatergite, with one row of 8 setae. (Figs 1 D, 5 A). Walking legs: first leg 0.9 times as long as second leg, procoxae not extended to the middle of the body; leg 15 length 0.26 (Figs 1 A – G, 5 A – B, D – E). Sternites from the first to penultimate leg-bearing segment: rectangular first metasternite (length / width ratio 1.2), other metasternites also rectangular, with a few large scattered setae; metasternite 16 length 0.15, width 0.12 (length / width ratio 1.25); most part of presternites exposed throughout the body, presternite of segment 16 with 0.12 times as long as previous metasternite, with one row of 8 setae (Figs 1 E, 5 C). Ultimate leg-bearing segment: metatergite in a semicircle shape, with two rows of 4 setae each, rectangular pretergite with one row of 6 setae; metasternite wider than long, trapezoidal, length 0.078, maximum width 0.113 (length / width ratio 0.7); presternite visible and concave in the middle part (Figs 1 F, 6 A). Ultimate legs straight, length 0.8 (2.8 times as long as penultimate leg), with seven articles (tarsus 2 present); each coxopleuron with 4 – 5 large coxal pores, most part opening close to the metasternite; tarsus 1 measuring 0.9 times as long as tibia (Figs 1 F, 6 A); terminal claw absent. Postpedal segments: membranous gonopods, without setae (Fig. 6 D). Sexual dimorphism. Males with ultimate legs just a little thickened (Fig. 1 G), with six articles (without tarsus 2, Figs 1 G, 6 C), ca. 2.3 times as long as the penultimate legs. Post pedal segments with many setae. Gonopods biarticulated, article 1 with 5 – 6 scattered setae, article 2 with 5 – 7 scattered setae. General morphology of the terminal part of the body as in Fig. 1 G. Variation. N = 6, including 3 ♀ and 3 ♂ (from a single locality): total body length: 6.5 − 7 mm. Leg-bearing segments: 33 or 35 (only one male with 33, all others specimens with 35). Coxal pores in each coxopleuron: 4 – 6. Natural history. The specimens were manually collected in forest soil in the Atlantic Forest biome (Fig. 7 B – E), usually found between the roots of trees, buried at about 4 − 10 cm deep, accessed for sampling mainly in ravines or recent landslides. Mecophilus carioca n. sp. is known only from the Parque Nacional de Itatiaia, where the specimens were sampled in the lowest part of the park.	en	Calvanese, Victor C., Brescovit, Antonio D.
