Venter pale green-grey, covered with short, golden setae. Dorsum and venter of body with tiny, black denticles. Dorsum covered with short, recumbent brown setae intermixed with large, golden setae; bearing long dark brown setae on sides of thorax and some shorter ones along sides of abdomen; male abdominal sternites with central long, yellow, setae; abdominal sternite VII and genital segments covered with abundant, small, golden setae. Vertex with one pair of dark setae; antennal segment I bearing eight long, stiff, erect black setae, two setae of this type also present near middle of segment II; legs with the usual pubescence and setae.

Apterous male. Length 3.53; maximum width 1.26. Length of antennal segments I −IV: 0.50, 0.34, 0.50, 0.50; pronotum shorter than the length of head (0.20/0.34), L/W: 0.20/0.94. Mesonotum, 0.72; length of exposed metanotum at midline 0.08.

All trochanters unarmed. Fore femur with sinuate upper margin; anterior tibia flattened and slightly dilate. Hind femur slightly increased ( Fig. 59 ), ventral surface in distal half with a row of 8 spines, beginning with a sharp, slender, forward-angling tooth and decreasing in size distally, proximal (largest) spine small, 3.6 less than width of femur (0.06/0.22); hind femur reaching apex of genital segment; hind tibia straight, armed only with a small spur at apex.

Proportions of male legs as follows: fore femur/tibia/ tarsal 2/ tarsal 3: 0.94/0.94/0.04/0.22; middle femur, length-width/ tibia/ tarsal 1/tarsal 2/tarsal 3: 1.50−0.20/0.98/0.08/0.36/0.60; hind femur length-width/ tibia/ tarsal 1/tarsal 2/tarsal 3: 1.20−0.22/1.22/0.06/0.14/0.32.

Abdomen L/W: 1.42/1.06. Median length of abdominal tergites as follows: I: 0.14, II: 0.18, III −V: 0.20, VI: 0.24, VII: 0.36, VIII: 0.32; connexiva angled upward at 20º. Venter slightly convex, and lacking longitudinal medial carina ; sternite VII>VI>V (0.22, 0.20, 0.18, respectively), ventrite VII depressed, with 2 (1+1) shallow depressions on either side of midline; genital segments well developed, proctiger ( Fig. 11 ), (L/W: 0.12/0.08, Fig. 38 ).

Apterous female. Length 4.06, maximum width 1.53, distinctly larger than male. Length of antennal segments I −IV: 0.50, 0.32, 0.44, 0.52. Hind femur usually reaching abdominal tergite VII, connexiva angled upward at 40º, apices of connexiva reaching halfway along tergite VIII. Abdomen L/W: 1.12/1.12. Median length of abdominal tergites as follows: I −VI: 0.22, V −VI: 0.26, VII: 0.30; tergites III −VI slightly depressed, tergite VIII horizontal and slightly convex, median length 0.38; basal width of tergite VII: 0.40; proctiger horizontal. Venter slightly convex; sternite VII>VI>V (0.26, 0.22, 0.20, respectively), caudal margin of sternite VII slightly produced medially. Gonocoxa well developed, distinctly visible.

Macropterous male. Length 4.06, maximum width (across humeral angles) 1.48. Similar in general coloration and structure to apterous male, with following exceptions: pronotum concave, brown, with anterior band yellow and covered with short, semi-recumbent, black setae intermixed with scattered, golden setae; anterior half dark brown, posterior half foveae and pale brown; humeral angles prominent and near right, apex rounded; L/W: 1.32/ 1.48. Hemelytra exceeding tip of abdomen, bearing 4 closed cells, 2 long cells originating in the basal portion of the wing followed by two smaller cells extending into the near to distal half, displaying uniformly dull brown, darker veins; Sc and R+M+Cu veins covered with short, semi-recumbent brown setae; outer rim of connexiva showing dorsally.

Macropterous female. Length 4.86, maximum width 1.50. Similar in general coloration and structure to winged male, with following exceptions: L/W: 1.52/1.5; hemelytra pale brown with darker veins, exceeding tip of abdomen.

Etymology. The name “ jagua ” refers to San Predro de Jagua , where the type was collected.

Comparative notes. Individuals of Rhagovelia jagua sp. n. may be recognized by the armature of the male hind leg, with the femur slightly incrassate and 5.4 longer than wider, with (1+7) spines ( Fig. 59 ), and the tibia with a small spur at the apex. The male and female possess glabrous, shining black central spots on abdominal tergites V −VII; the lateral margins of the basal proctiger are slightly concave ( Fig. 11 ), and the male paramere is rounded, bearing three long setae near at the central part ( Fig. 38 ). Superficially this species resembles R. tantilla Drake & Harris, 1933 but the latter taxon is smaller and less robust than R. jagua , with rounded lateral lobes on the basal section of the proctiger ( Fig. 12 ); and the paramere with a triangular apex, and bearing scattered, small setae ( Fig. 39 ). Additionally, it is also similar to R. pacifica Padilla-Gil 2010 , but in that species the posterior femur has five spines; the posterior tibia lacks spines; the ratio of the lengths of antennal segments I and II equals 1.7 (versus 2.6 in R. jagua ); the male proctiger has the lateral lobes greatly developed and rounded (compare Figs. 11, 13 ); and the male paramere has a triangular-shape apex and is rounded on the basal section (compare Figs. 38, 40 ).
