Etymology
The new species is named after Caupé, the Tupí- Guaraní divinity of beauty.
Description
Maximum length: ♂, 2.7 mm; ♀, 3 mm. Body outline as in Figure 20A View Figure 20 . Colour yellowish brown. Dorsum covered with sparse lanceolate scale setae ( Fig. 20B View Figure 20 ). Noduli laterales inserted more or less at the same distance from the lateral margin of pereonites; b/c and d/c coordinates as in Fig 20C View Figure 20 ; gland pores not visible. Cephalon ( Fig. 20D, E View Figure 20 ) with suprantennal line straight; eye with four ommatidia. Pleonites 3–5 with epimera reduced, adpressed, with no posterior points ( Fig. 20A View Figure 20 ). Telson with distal part triangular with slightly concave sides and obtuse apex ( Fig. 20F View Figure 20 ). Antennule ( Fig. 20G View Figure 20 ) of three articles similar in length, third article with two apical aesthetascs and one tuft of six aesthetascs on medial margin. Antenna ( Fig. 20H View Figure 20 ) reaching mid pereonite 3; flagellum slightly shorter than fifth article of peduncle, third article longer than second and third, third article bearing one row of two aesthetascs, apical organ as long as distal article of flagellum, showing sensory hairs enclosed by a common tube-like sheath, free sensilla short and inserted at one quarter of the length of the apical organ. Buccal pieces ( Figs 20I,J View Figure 20 , 21A–C View Figure 21 ) similar to those of the preceding species. Pereopod ( Figs 21E View Figure 21 , 22A View Figure 22 ) dactylus with ungual and dactylar setae having simple apex and reaching tip of outer claw. Uropod ( Fig. 21D View Figure 21 ) protopod grooved on the distal half of the outer margin; exopod longer than endopod; insertion of endopod proximal to that of exopod.
Male: Pereopod 1 ( Fig. 21E View Figure 21 ) and pereopod 7 ( Fig. 22A View Figure 22 ) with no distinct sexual modifications. Genital papilla ( Fig. 22B View Figure 22 ) with a triangular ventral shield and two subapical orificies. Pleopod 1 ( Fig. 22C,D View Figure 22 ) exopod triangular, with outer margin concave and medial margin convex; endopod about twice longer than exopod, distally pointed and bent outwards, with a line of short setae near medial margin. Pleopod 2 ( Fig. 22E View Figure 22 ) exopod triangular, outer margin slightly concave, bearing three setae; endopod distinctly longer than exopod. Pleopods 3–5 exopods ( Fig. 22F–H View Figure 22 ) subquadrangular, with distal margins slightly concave and bearing two, four, and three setae, respectively.
Remarks
Metaprosekia caupe sp. nov. can be distinguished from M. nodilinearis by the eye with four instead of three ommatidia, the smaller number of aesthetascs on the antennule (eight instead of 12), and the male pleopod 1 exopod with shorter distal point and more concave outer margin. It is very similar to M. quadriocellata sp. nov., from which it differs mainly in the shape of the male pleopod 1 exopod, with a smaller distal point, and endopod, with the apical part less bent outwards.
