ETYMOLOGY. — The new species is named after the native Brazilian Cactaceae Cereus jamacaru , also known as Mandacaru, typical for xeric environments. This name is used also for the locality where the specimens were collected, namely Gruta do Mandacaru.
DESCRIPTION
Maximum body length: ♂ and ♀ 3 mm. Color brown with typical muscle spot insertions; cephalon, pereonites 1-5 posterior portion, pereonites 6 and 7, pleon and telson more pigmented. Body outline as in Figure 11A View FIG . Pereonite 1 slightly directed frontwards, not surpassing cephalon, pereonites 2-7 gradually more arched and directed backwards. Dorsal surface densely covered with fan-shaped scale-setae ( Fig. 11B View FIG ). One line of piliform noduli laterales per side, longer than scale-setae ( Fig. 11B View FIG ); d/c and b/c coordinates as in Figure 11C and D View FIG , respectively. Cephalon ( Fig. 11E, F View FIG ) with rounded lateral lobes, suprantennal line bent down in middle; eyes with 5-6 ommatidia. Pleon slightly narrower than pereon, epimera slightly developed, acute and directed backwards ( Fig. 11A View FIG ). Telson ( Fig. 11G View FIG ) with lateral sides slightly concave, apex right-angled. Antennula ( Fig. 11H View FIG ) distal article longest bearing about seven aesthetascs in two rows plus apical pair. Antenna ( Fig. 11I View FIG ) reaching second pereonite when extended backwards; flagellum with first and second articles subequal in length, third article bearing lateral aesthetascs, apical organ bearing two long free sensilla. Mandibles ( Fig. 11J, K View FIG ) with molar penicil of about five branches. Maxillula ( Fig. 11L View FIG ) inner endite with two hairy penicils, distal margin rounded; outer endite with 4+3 teeth, two apically cleft at apex, outer margin strongly concave equipped with long setae. Maxilla ( Fig. 11M View FIG ) inner lobe rounded covered with thick setae; outer lobe twice as wide as inner lobe covered with thin setae. Maxilliped ( Fig. 11N View FIG ) palp with proximal article bearing two long setae; endite subrectangular, medial seta surpassing distal margin, distal margin sinuous. Dactylus of two claws subequal in length, dactylar and ungual setae simple, not surpassing outer claw. Uropod ( Fig. 12A View FIG ) protopod subquadrangular, protopod and exopod grooved on outer margin, exopod longer than endopod, endopod inserted almost at same level.
Male
Pereopod 7 without apparent sexual dimorphism ( Fig. 12B View FIG ). Genital papilla ( Fig. 12C View FIG ) with triangular ventral shield, papilla longer than ventral shield bearing two subapical orifices. Pleopod 1 ( Fig. 12D View FIG ) exopod subtriangular, slightly longer than wide, inner margin rounded, outer margin slightly concave; endopod stout, longer than exopod, medial portion with lobe, distal portion triangular, directed outwards, bearing short setae on medial margin. Pleopod 2 ( Fig. 12E View FIG ) exopod triangular, outer margin concave bearing four long setae; endopod longer than exopod. Pleopod 3 and 4 exopods ( Fig. 12F, G View FIG ) triangular, outer margin almost straight bearing long setae. Pleopod 5 exopod ( Fig. 12H View FIG ) triangular, outer margin slightly convex bearing long setae.
REMARKS
Novamundoniscus mandacaru Campos-Filho, Araujo & Bichuette , n. sp. is readily distinguished from the congeneric species in the shape of the male pleopod 1.
This species is considered to be a troglophile due to the absence of troglomorphic characters. The cave where the specimens of N. mandacaru Campos-Filho, Araujo & Bichuette , n. sp. were collected is inserted in the Caatinga domain ( Morrone et al. 2022). Probably the species inhabits caves due to their resources and favorable micro-habitat conditions ( Fernandes et al. 2016, 2019).
