Type material
Holotype: ♂, Brazil, Pará, Altamira, Caverna Pedra da Cachoeira , 3°19′13″S, 52°19′22″W, 15 December 2010, leg. M.E. Bichuette ( MZUSP 27541 View Materials ). GoogleMaps
Paratypes: Five ♂ (one in micropreparations) and three ♀, same data as holotype ( MZUSP 27542 View Materials ) GoogleMaps .
Etymology
The new species is named after Curupira, a mythological creature of Brazilian folklore. In Tupi language kuru′ pir means covered with blisters, and the character is known as the protector of forests and animals.
Description
Maximum length: ♂ and ♀, 3 mm. Body outline as in Figure 32A View Figure 32 . Colour pale yellow. Dorsum covered with fan-shaped scale setae ( Fig. 32F View Figure 32 ); one line of noduli laterales inserted more or less at the same distance from the lateral margin of pereonites; b/c and d/c coordinates as in Figure 32B View Figure 32 . Cephalon ( Fig. 32C,D View Figure 32 ) with small lobes, no frontal line, supranatennal line straight; eye reduced, with three ommatidia. Pleon ( Fig. 32A View Figure 32 ) slightly narrower than pereon, epimera of pleonites 3–5 well developed, falciform. Telson ( Fig. 32E View Figure 32 ) with triangular distal part, concave sides, and rounded apex. Antennule ( Fig. 32G View Figure 32 ) of three articles, distal joint with nine apical aesthetascs. Antenna ( Fig. 32H View Figure 32 ) short and stout, with flagellum as long as fifth article of peduncle, second flagellar article about three times as long as first, apical organ short. Mouth parts as in T. yiara sp. nov. Pereopod dactylus with short inner claw; ungual and dactylar seta, with simple distal part reaching tip and middle of outer claw, respectively ( Fig. 33A View Figure 33 ). Uropod ( Fig. 32I View Figure 32 ) protopod grooved on outer margin; exopod stout and longer than endopod; insertions of endopod and exopod almost at the same level.
Male: Pereopod 1 ( Fig. 33A View Figure 33 ) carpus and, to a lesser extent, merus with a line of long setae on sternal margin. Pereopod 7 ( Fig. 33B View Figure 33 ) with no peculiar modifications; ischium with sternal margin straight. Pleopod 1 ( Fig. 33C View Figure 33 ) exopod ovoid; endopod with distal part bearing a few setae near medial margin. Pleopod 2 ( Fig. 33D View Figure 33 ) exopod triangular, outer margin slightly concave; endopod longer than exopod. Pleopods 3–5 exopods as in Figure 33E–G View Figure 33 .
Remarks
In the eye with three ommatidia, T. curupira sp. nov. resembles Trichorhina mulaiki Schmalfuss, 2003 from Mexico and Trichorhina triocellata Ferrara & Taiti, 1985 from Aldabra Island. It differs from T. mulaiki in the pale colour, the presence of cephalic lobes, and the telson with rounded instead of pointed apex; it differs from T. triocellata in the less wide body shape, different shape of dorsal scale setae, and lack of tuft of setae on pereopod dactylus. In Brazil, other species of Trichorhina have a reduced number of eyes, e.g. Trichorhina acuta Araujo & Buckup, 1994 , Trichorhina heterophthalma Lemos de Castro, 1964 , and Trichorhina sexdens Souza, Araujo & Campos-Filho, 2011 . The new species is readily distinguishable from those species by the different shape of the dorsal scale setae, by the different shape of the endite of the maxilliped, and by the different shape of the male pleopod 1.
