Description.
Maximum body length: male 4.5 mm, female 5 mm. Body outline as in Fig. 3A, B View Figure 3 . Colourless (Fig. 3B View Figure 3 ). Dorsal surface granulated bearing pointed scale-setae (Fig. 3A, C, D View Figure 3 ). Cephalon (Fig. 3E-G View Figure 3 ) with small semicircular antennary lobes; eyes absent. Pereonites 1-2 with epimera semicircular, 3-7 with posterior corners gradually more acute (Fig. 3A, B, D, F, G View Figure 3 ). Pleon (Fig. 3H View Figure 3 ) narrower than pereon, pleonite 3-5 epimera elongated and acute. Telson (Fig. 3H View Figure 3 ) broader than long, lateral sides almost straight, rounded apex. Antennula (Fig. 3I View Figure 3 ) distal article longest with four apical aesthetascs. Antenna (Fig. 4A View Figure 4 ) long, not surpassing pereonite 3 when extended backwards; flagellum of articles subequal in length; apical organ shorter than basal article of flagellum, bearing small free sensilla. Mandibles with molar penicil of six to seven branches; right mandible (Fig. 4B View Figure 4 ) with 1+1 free penicils; left mandible (Fig. 4C View Figure 4 ) with 2+1 free penicils. Maxillula (Fig. 4D View Figure 4 ) inner endite bearing two setose penicils, distal margin rounded; outer endite with 4 + 4 teeth simple, elongated and curved. Maxilla (Fig. 4E View Figure 4 ) with setose lobes; outer lobe slightly smaller than inner lobe, quadrangular and covered with thin and long setae; inner lobe rounded and covered with thin and thick setae. Maxilliped (Fig. 4F View Figure 4 ) basis rectangular; first article of palp bearing two setae; endite rectangular, medial seta overpassing distal margin, ventrally with setose sulcus. Uropod (Fig. 4G View Figure 4 ) protopod and exopod grooved on outer margin. Pereopods 1-7 bearing sparse setae on sternal margin. Pereopod 1 (Fig. 5A View Figure 5 ) carpus with antennal grooming brush reduced, composed by short scale-setae; dactylus with ungual and dactylar setae simple (Fig. 5B View Figure 5 ). Pleopod exopods without respiratory areas.
Male. Pereopod 1-7 (Fig. 5A-H View Figure 5 ) gradually more elongated, without particular modifications. Genital papilla (Fig. 6A View Figure 6 ) with lanceolate ventral shield; papilla longer than ventral shield bearing two subapical orifices. Pleopod 1 (Fig. 6A View Figure 6 ) exopod ovoidal, inner margin with one small seta; endopod stout, three times longer than exopod, slightly bent outwards, apex bearing setae on inner margin. Pleopod 2 (Fig. 6E View Figure 6 ) exopod triangular, outer margin concave bearing four setae; endopod flagelliform, slightly longer than exopod. Pleopod 3 and 4 (Fig. 6C, D View Figure 6 ) exopods rhomboid, outer margin with four setae, inner margin slightly convex. Pleopod 5 (Fig. 6E View Figure 6 ) exopod rhomboid, longer than wide, distal and outer margins rounded bearing four small setae.
Etymology.
The new species name alludes to the resistance group from the Star Wars fiction series, the Rebel Alliance, that fights against the Empire. The Kadiwéu indigenous people were known as warriors, and they fought for Brazil in the Paraguayan War to reclaim and secure their lands in the Serra da Bodoquena region. Today, they are confined to the outskirts of the Bodoquena plateau and the Pantanal plain. The designation ‘rebellis’ is used as an adjective for the genus name.
Ecological remarks.
The physicochemical data of microhabitats of Kadiweuoniscus rebellis gen. et sp. nov. are: pH = 7.5, high conductivity (c. 0.450 µS.cm-1), moderate temperature (22 °C) and moderate dissolved oxygen (ca. 6.0 mg.l-1). pH values (neutral to basic) are typical of karst waters. The abundance is particularly low in each cave, and they have a preference for rocky substrates with a silty and pebble bottom (Fig. 7A, B View Figure 7 ). Amphibious habit (see Suppl. material 1).
