General color dark brown; central part of abdominal sternite VII, genital segments, outer rim of connexiva, greater part of antennae, rostrum, and legs, shining black. Anterior transverse band of pronotum, basal third of first antennal segment, acetabula, coxae and trochanters of fore and hind legs, and basal third of fore femur, yellow. Venter pale grey, covered with large, golden setae. Dorsum and venter of thorax and abdomen, lacking of black denticles, jugum of head and proepisternum without black denticles. Dorsum covered with short, recumbent black setae intermixed with large, golden setae; bearing long, dark setae on sides of thorax and some shorter ones along sides of abdomen; 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. Apteorus male. Length 3.04; maximum width 1.1. Length of antennal segments I −IV: 0.40, 0.36, 0.48, 0.52; pronotum shorter than the length of head, L/W: 0.16/0.90. Mesonotum convex, length, 0.64; length of exposed metanotum at midline 0.08. All trochanters unarmed, posterior femur weakly increased, ventral surface in distal half with a row of 6 spines, beginning with a sharp, slender, forward-angling tooth and decreasing in size distally, proximal (largest) spine small, 2.8 less than width of femur (0.1/0.28), hind femur, extending slight beyond apex of abdomen (0.08); hind tibia straight, unarmed. Proportions of male legs as follows: fore femur/tibia/ tarsal 2/ tarsal 3: 0.80/0.90/0.06/0.20; middle femur, length-width/ tibia/ tarsal 1/tarsal 2/tarsal 3: 1.50−0.24/1.0/0.06/0.42/0.76; hind femur length-width/ tibia/ tarsal 1/ tarsal 2/tarsal 3: 1.10−0.28/1.10/0.04/0.08/0.20. Abdomen L/W: 1.02/1.36. Median length of abdominal tergites as follows: I, III, and V: 0.16, II and IV: 0.14, VI: 0.20, VII: 0.38, VIII: 0.30; connexiva angled upward at 10º. Venter lacking longitudinal medial carina ; sternite VII: 0.20, sternite V and VI equal (0.16), ventrites VII and VIII slightly depressed on posterior half, with 2 (1+1) shallow depressions on either side of midline; proctiger ( Fig. 10 ) and parameres ( Fig. 36 ). Apterous female. Length 3.32, maximum width 1.24, distinctly larger than male. Length of antennal segments equal to the male. Posterior femur usually reaching gonocoxa, connexiva angled upward at 20º, covered with large, black setae, apices of connexiva slightly rounded, reaching halfway along tergite VIII. Abdomen L/W: 1.36/1.20. Median length of abdominal tergites as follows: I and VI: 0.22, II and V: 0.20, III and IV: 0.16, VII: 0.30; tergites IV −VII, glabrous, tergite VI with a shining black, central spot, tergites III −VI slightly concave, tergite VIII horizontal and slightly convex, median length 0.36; basal width of tergite VII: 0.40; proctiger horizontal. Venter slightly convex; sternite VII>VI>V (0.56, 0.22, 0.18, respectively), caudal margin of sternite VII slightly produced medially. Gonocoxa well developed, distinctly visible. Macropterous form: unknown. Etymology . The name “ tumaquensis ” refers to the city of Tumaco, near which the type series of this species was collected. Comparative notes . Individuals of Rhagovelia tumaquensis sp. n. may be distinguished by the armature of the hind femur (1+5); the structure of the hind tibia which lacks teeth or an apical spur; the length of the hind femur which extends slightly beyond the apex of the abdomen (0.08); the length of the mesonotum, which is eight times longer than the metanotum; and by the shapes of the male proctiger and paramere ( Figs. 10 , 36 ). The apterous female has abdominal sternite VII 2.5 longer than sternite VI. The male paramere of Rhagovelia tumaquensis is similar to that of Rhagovelia evidis Bacon, 1948 (compare Figs. 36, 37 ) but the latter species is smaller (male L/W: 2.50/1.03), with a spur on the posterior tibia; the middle trochanter is yellow or white (in R . tumaquensis , by contrast, the middle trochanters are shining black); the structure of last ventral abdominal segment of male is characteristic; and there are other morphometric differences involving the antennae, thorax, and hind femur length and width.
