description: Remaneicaris jujuyensis (Noodt, 1965)

Synonyms: Parastenocaris jujuyensis (Noodt 1965); Remaneicaris jujuyensis (Jakobi 1972); Parastenocaris jujuyensis (Rouch 1986); Parastenocaris jujuyensis (Dussart & Defaye 1990); Remaneicaris jujuyensis (Corgosinho & Martínez Arbizu 2005)
Material examined: Noodt's collection; C134 (M3, slide 7; locus typicus). Locus typicus: Quebra Honda, 3 km north of Jujuy, Jujuy Argentina.
Male: Length 420 µm (Noodt's measurement). Rostrum not fused to Cph, with wide base and two sensilla on tip. Cph with 1 dorsal integumental window; Urs integumental windows not see in Noodt's preparations. Anal operculum smooth and slightly concave, with small protuberance on each side of paraopercular region, just above furca. Furca (Fig. 3F) shorter than telson, 2 times longer than wide, tapering in lateral view, setae I–III and VII at the distal 1/3 opposite to each other, setae I–III approximately of same size, seta V the longest, seta IV longer than seta VI and VII, seta VI minute, approximately as long as lateral setae, seta VII approximately 1/3 shorter than seta IV. A1 and A2 armature and segmentation as described by Corgosinho eta al. (2007b) for R. tridactyla. A1: 9- segmented and haplocer; armature beginning with proximal segment: 0/5/4/2/5+Ae/1/4/2/9+ Ae. A 2: with allobasis; 1-segmented exp with 1 seta, and 1-segmented enp bearing 7 setae. Md, Mx 1, Mx 2 and Mxp armature as described by Corgosinho eta al. (2005, 2007a, 2007b and 2010a); Mx 2: of Remaneicaris type, with two slender setae on proximal and 3 setae on distal endite. P1 (Fig. 3A): basis with outer seta, 3 spinules on outer margin; enp 2-segmented, enp-1 as long as exp-1 and 2, without ornamentation on inner margin, outer margin with 2 spinules at proximal 1/3 and 2 spinules at distal 1/3; enp-2 with 3 spinules on inner margin, 1 unipinate outer spine and 1geniculated seta 2,5 times as long as outer spine; exp 3-segmented, exp-1 with outer spine and rows of spinules on outer margin, exp-2 unarmed, with spinules on outer margin, exp-3 with spinules on outer margin, 1 unipinate outer spine on distal 1/3, 1 unipinate outer spine and 2 geniculated setae, innermost the longest one. P2 (Fig. 3B):basis without outer seta, ornamented with 1 row of spinules on outer margin, 1 pore near anterior margin, and 1 row of small spinules near enp insertion; exp 3-segmented, exp-1 longer than each of the remaining two segments; with PRVS on outer margin, row of spinules anterior to insertion of outer spine, 3 spinules of different sizes distal to outer spine and inner hyaline frill; exp-2 without armature, with 1 spinule medially on outer margin and row of spinules of unequal sizes at distal margin (innermost spinules smaller than outermost); exp-3 with 1 spinule located medially on outer margin, 1 spinule on distal 2/3 of outer margin, distal hyaline frill, 1 unipinate subapical spine and 2 bipinate apical setae, outer seta shorter than inner one; enp 1-segmented, long, dilated subproximally, approximately of same size of exp1, with 1 long unipinate and spiniform distal seta, 2 subdistal spinules and 4 spinules on outer margin. P3 (Fig. 3C): coxa with posterior row of small spinules; basis with outer seta; enp 1- segmented, with row of spinules proximally, on inner margin, very long, dagger like, proximally dilated, almost as long as exp; exp 1-segmented, straight, on the outer margin with row of 4 larger spinules proximally, 3 spinules on distal 2/3 and 1 modified spinule on distal 1/3 with hyaline lamella on inner margin, inner margin with process on FIGURE 3.

distal 2/3,; apophysis shorter than thumb, triangular, ending in a blade-like hyaline lamella which is inwardly turned at the end of a straight exp, conferring to it a final angle of approximately 90° with the main exp axis; thumb is long, almost 2/3 as long as exp, strongly curved inwards (s-shaped). P4 (Fig.3D): basis with outer seta and 1 pore on anterior margin; exp 3-segmented, exp-1 longer than each of the remaining two segments with PRVS on outer margin, row of spinules anterior to insertion of outer spine, 2 spinules of different sizes distal to outer spine and inner hyaline frill; exp-2 without armature, with 1 spinule medially on outer margin and row of spinules of unequal sizes at distal margin (innermost spinules smaller than outermost); exp-3 with 1 bipinate apical seta and 1 unipinate spine at 2/3 of outer margin, 1 distal hyaline frill, 2 spinules on proximal 1/3 and 1 medially spine on outer margin; enp 1-segmented, more than 3 times shorter than exp-1, concave on outer margin and with row of spinules along inner and convex margin. P5 (Fig. 3E): as described by Noodt (1965), without intercoxal sclerite, 2 plate not fused to the somite, rectangular, ending in small process on inner margin, with 1 long outer seta and 3 smooth distal setae, distalmost seta the longest, proximalmost seta the shortest.
Female: Sexually dimorphic in A1, P2, P3, P4, P5 and genital field. Length 360 µm (Noodt's measurement). Rostrum as in male. Integumental windows probably as in males. Telson and furca as in male. A1 armature and segmentation as described by Corgosinho eta al. (2007b) for R. tridactyla. A1: 7-segmented; number of setae beginning at proximal segment: 0/4/5/2+Ae/1/2/9+Ae. A2: as in male. P2: enp slightly weaker than enp of males, appearing as long appendix with long distal setae and 3 spinules on outer margin. P3 (Fig. 3G): basis with 1 outer seta and row of spinules near insertion of enp; exp 2-segmented, exp-1 with proximal row of spinules, an outer spine, 2 long spinules near to outer spine, 1 small spinule posterior to outer spine, and 2 small spinules distally, on inner margin; exp-2 with 1 spine at 3/4 of the outer margin, 1 bipinate distal seta and 1 medial spinule on outer margin, 1 spinule near outer spine and distal hyaline frill; enp 1-segmented, spiniform, 0.8 times as long as exp- 1 in length, with 2 spinules on middle margin. P4: not observed; probably as described by Noodt (1965), without sexual dimorphism on exp. P5: as in male except for the larger inner process. Genital field with 1 copulatory pore located medially. Gonopore with transversal slit.
