Venter convex, lacking longitudinal medial carina , sternite VII>VI>V (0.30, 0.20, 0.18, respectively), ventrite VII depressed on half, with 2 (1+1) depressions on either side of midline; ventrite VIII with keel along midline ventral; genital segments well developed, proctiger ( Fig. 14 ), parameres L/W: 0.16/0.06 ( Fig. 41 ).

Apterous female. Length 4.4, maximum width 1.68. Length of antennal segments I −IV: 1.0, 0.70, 0.70, 0.62. Posterior femur L/W: 1.84−0.26, extending 0.24 beyond apex of abdomen; hind tibia straight, with a longitudinal row of 15 small black pegs; moderate-length, conical, black, apical spur; connexival margins of segments V −VII thinned, posterolateral, connexiva angled upward at 30º, apices of connexiva straight, reaching basal ¾ of tergite VIII. Abdomen L/W: 1.76/1.64. Median length of abdominal tergites as follows: I: 0.20, II and IV: 0.24, III and V: 0.26, VI: 0.30, VII: 0.36; tergite VIII angled downward at 30º, median length 0.32; basal width of tergite VII: 0.50; proctiger semi-vertical. Venter, sternite VII>VI>V (0.52, 0.28, 0.26, respectively); gonocoxa evident.

Macropterous Male. Length 3.72, maximum width 1.74. Similar in general coloration to apterous male, with following exceptions: length of antennal segments I −IV: 1.10, 0.74, 0.80, 0.70. Pronotum brown, with anterior band yellow and covered with short, semi-recumbent black setae; posterior half pale brown and with black punctuations, humeral angles prominent and rounded, apex rounded; L/W: 1.54/1.74. Hemelytra exceeding (0.60) tip of abdomen, bearing 4 closed cells, 2 long cells originating in the basal portion of the wing followed by two smaller cell, displaying uniformly dull brown, darker veins; Sc and R+M+Cu veins covered with short, semirecumbent brown setae; anterior half hemelytra showing outer rim of connexiva.

Type locality. Rhagovelia mocoa sp. n., was collected in the Río Mocoa , located at 1º 8’ 51” N, 76º 38’ 27” W, 550 m, Mocoa Municipality, in the Putumayo department.

Etymology. The name “ mocoa ” is a noun in apposition, and refers to the locality type.

Comparative notes. Individuals of Rhagovelia mocoa are characterized by the shape of the posterior femur, with a sinuate upper margin and (1+8) spines ventrally ( Fig. 60 ); and the shapes of the male proctiger ( Fig. 14 ) and paramere ( Fig. 41 ). The male paramere shape is similar to R. carina n. sp. (compare Figs. 30, 41 ) but the latter species is larger (body L/W: 5.13/1.76); the male hind femur has the upper margin not sinuate (compare Figs. 58, 60 ), and has (1+10) spines ventrally; and the male proctiger has a triangular distal cone ( Fig. 4 ), compared to a rounded distal cone on the proctiger of R. mocoa ( Fig. 14 )
