03E41D3CFFF06B46FE38FA38FBCCE05A.taxon	etymology	Etymology ‘ Aranã’ is the Portuguese (Brazil) name for an indigenous Brazilian tribe in the ‘ Vale do Jequitinhonha’ region, which is near the type locality. Today, their population has been nearly extinguished, so the new species is named in honour of these people.	en	Rabet, Nicolas, Lacau, Sébastien, Bozelli, Reinaldo L.

03E41D3CFFF46B46FE70FD74FCBDE7D5.taxon	description	Description Similar to the original description (see Rogers et al. 2012) including the following variations: branch 2 V variable with one to three extremities, the tip of each with a cell pad. Branch 2 A with a basal spine of varying shape from sinuate to straight (Fig. 4 A – B). One or two basal cell pads produced. Anterior end sometimes arcuate or straight but always acute apically (Fig. 4 A – B). Sub-branch III of branch 2 D with varying shape from monoramal to biramal with various intermediate states. In some cases, three or five spiniform projections present in the posterior face of the sub-branch (Fig. 4 C – D). In some individuals, two projections can fuse to form an elongate projection with two acute extremities (Fig. 4 E – F) or form an elongate ramus sharing spiniform projections as in the original description (see Rogers et al. 2012). Habitat The specimens studied in the present work were all collected in natural pools in an Amazonian savannah in the Serra dos Carajás (Canga deposits), see Fig. 7 B.	en	Rabet, Nicolas, Lacau, Sébastien, Bozelli, Reinaldo L.

03E41D3CFFF46B4BFE33F9F8FE28E0D4.taxon	materials_examined	Material examined Holotype BRAZIL: mature Ƌ, total length 15.0 mm, cercopods 2.8 mm, Serra dos Carajás, Pará, 6 ° 21 ′ 06.27 ″ S, 50 ° 23 ′ 43.66 ″ W, pool S 11 - BC in an Amazonian savannah (Canga deposits), 25 Nov. 2013, R. Bozelli leg. (MNRJ 2973). In the same study period, approximately 30 phytoplankton species, 30 zooplankton species and 15 aquatic macrophyte species were recorded in the pool, but no fish were observed. Allotype BRAZIL: mature ♀, total length 12.8 mm, brood pouch 2.9 mm reaching the extremity of the 6 th abdominal segment (including genital segments), cercopods 2.7 mm, same collecting data as for holotype (MNRJ 2974). Paratypes BRAZIL: 8 ƋƋ, same collecting data as for holotype, total length 15.1 to 16.5 mm, mean = 15.75 ± 0.58 mm, cercopods 2.3 to 2.7 mm, mean = 2.56 ± 0.15 mm; 1 ♀, same collecting data as for holotype, length 13.5 mm, brood pouch 3 mm, cercopods 3 mm (2 ƋƋ, 1 ♀ MNHN (MNHN-IU- 2016 - 3559); 2 ƋƋ in MNRJ (MNRJ 2975 )). Other specimens are kept in personal collections of NR and RLB. Type locality (Figs 1, 7 I) Pool S 11 - BC is the smallest (average area of 0.13 ha) among the previously studied lentic aquatic environments in the Serra dos Carajás inside the Carajás National Forest. Although very shallow (0.10 to 0.25 m) during our sporadic explorations from 2005 – 2013, the pool was never found completely dry, and during this period, its volume ranged from 56 to 140 m 3. Nevertheless, it is a temporary pool because it was possible to verify that the pool dried up in Google Earth images from August 2006. The electrical conductivity of the water varies between 4 and 64 μS / cm and pH varied between 4.89 and 5.63. The recorded turbidity values were between 1 and 64 NTU, but the water was always completely transparent.	en	Rabet, Nicolas, Lacau, Sébastien, Bozelli, Reinaldo L.
