Color and pilosity. General color brown; central spot of abdominal tergites VI and VIII; genital segments, margins of metasternum, outer rim of connexiva, greater part of antennae, rostrum and legs, shining black. Anterior transverse band of pronotum, basal 1 / 4 of first antennal segment; coxae of fore and hind legs, yellow. Venter pale green, covered with short, semi-recumbent, golden setae; body covered with bright black denticles. Dorsum covered with short, recumbent golden setae intermixed with scattered, long, black setae; bearing long dark setae on sides of thorax; abdominal sternites VII, VIII and genital segments covered with abundant, small golden setae. Antennal segment I bearing six 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 3.92; maximum width 1.52. Length of antennal segments I −IV: 1.30, 0.82, 0.82, 0.64; pronotum shorter than the length of head (0.38 / 0.22), L/W: 0.22 / 1.28; length of exposed mesonotum 1.06; length of exposed metanotum at midline 0.08.

Trochanters unarmed. Posterior femur with sinuate anterior and posterior margins ( Fig. 60 View FIGURES 55 − 60 ), ventral surface in distal half with a row of 9 spines ( Fig. 60 View FIGURES 55 − 60 ), beginning with a sharp, slender, forward-angling tooth and decreasing in size distally, proximal (largest) spine 1.6 less than width of femur (0.32 / 0.2): hind femur beyond 1.0 the apex of abdomen. Hind tibia straight, with a longitudinal row of 18 small, black pegs, 10 along basal half and 8 along posterior half; moderate-length, conical, black, apical spur.

Proportions of male legs as follows: fore femur/tibia/tarsal 1 /tarsal 2: 1.30 / 1.46 / 0.06 / 0.36; middle femur/tibia/ tarsal 1 /tarsal 2 /tarsal 3: 2.68 / 1.60 / 0.10 / 1.04 / 0.94; hind femur/ tibia/ tarsal 1 /tarsal 2 /tarsal 3: 2.16 /2.0/ 0.082 / 0.24 / 0.34.

Abdomen with length (tergites I −VII)/width (basal): 1.48 / 1.40. Median length of abdominal tergites as follows: I: 0.14, II −V: 0.18, VI: 0.22, VII: 0.40, VIII: 0.36; connexiva angled upward at 30 º. 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 View FIGURES 11 − 14 ), parameres L/W: 0.16 / 0.06 ( Fig. 41 View FIGURES 25 − 54 ).

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 30 º, 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 30 º, 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 1 º 8 ’ 51 ” N, 76 º 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 View FIGURES 55 − 60 ); and the shapes of the male proctiger ( Fig. 14 View FIGURES 11 − 14 ) and paramere ( Fig. 41 View FIGURES 25 − 54 ). The male paramere shape is similar to R. carina n. sp. (compare Figs. 30, 41 View FIGURES 25 − 54 ) 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 View FIGURES 55 − 60 ), and has (1 + 10) spines ventrally; and the male proctiger has a triangular distal cone ( Fig. 4 View FIGURES 1 − 5 ), compared to a rounded distal cone on the proctiger of R. mocoa ( Fig. 14 View FIGURES 11 − 14 )
