Rhagovelia umbria sp. n.

Type material. HOLOTYPE, apt M, allotype apt F: COLOMBIA, Putumayo, Puerto Umbría , Río Guineo, 225 m, 8 II 2012, leg. O. Arcos ( ICN). PARATYPES, same data as holotype, 1 apt M, 7 apt F (PSO-CZ).

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 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 3.68; maximum width 1.44. Length of antennal segments I −IV: 1.10, 0.68, 0.66, 0.60; pronotum shorter than the length of head (0.30 / 0.20), L/W: 0.20 / 1.20; length of exposed mesonotum 0.96; length of exposed metanotum at midline 0.10. Mesonotum depressed on distal half.

Trochanters unarmed. Posterior femur, with sinuous dorsal margin, ventral surface in distal half with a row of 14 spines, 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 0.36 the apex of abdomen. Hind tibia slightly curve, with a longitudinal row of 25 small, black pegs, and conical, black, apical spur.

Proportions of male legs as follows: fore femur/tibia/tarsal 1 /tarsal 2: 1.32 / 1.52 / 0.08 / 0.30; middle femur/tibia/ tarsal 1 /tarsal 2 /tarsal 3: 2.28 / 1.44 / 0.10 / 0.92 / 0.84; hind femur L-W/ tibia/ tarsal 1 /tarsal 2 /tarsal 3: 1.76 − 0.32 / 1.6 / 0.06 / 0.14 / 0.32.

Abdomen with length (tergites I −VII)/width (basal): 1.40 / 1.48. Median length of abdominal tergites as follows: I: 0.14, II −V: 0.16, VI: 0.20, VII: 0.38, VIII: 0.30; connexiva angled upward at 30 º. Venter convex, lacking longitudinal medial carina , sternite VII>VI>V (0.28, 0.18, 0.16, respectively), ventrite VII depressed on half, with 2 (1 + 1) depressions on either side of midline; genital segments well developed, proctiger ( Fig. 15 View FIGURES 15 − 19 ), parameres L/W: 0.18 / 0.06 ( Fig. 42 View FIGURES 25 − 54 ).

Apterous female. Length 4.46, maximum width 1.64. Length of antennal segments I −IV: 0.92, 0.64, 0.64, 0.56. Posterior femur L/W: 1.60 − 0.28, reaching apex of abdomen; hind tibia with a longitudinal row of 20 small black pegs; moderate-length, conical, black, apical spur; connexival margins of segments V −VII thinned, posterolateral, connexiva angled upward at 40 º, apices of connexiva straight, reaching basal ¾ of tergite VIII. Abdomen L/ W: 1.80 / 1.64. Median length of abdominal tergites as follows: I: 0.20, II and IV: 0.22, III: 0.24, V: 0.26, VI: 0.28, VII: 0.34; tergite VIII angled downward at 10 º, median length 0.30; basal width of tergite VII: 0.48; proctiger semihorizontal. Venter, sternite VII>VI>V (0.54, 0.32, 0.28, respectively); gonocoxa evident.

Macropterous Male. Length 4.46, maximum width 1.6. Similar in general coloration and structure to apterous male, with following exceptions: length of antennal segments I −IV: 1.28, 0.80, 0.80, 0.72; 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: 1.66 / 1.6; hemelytra 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, semi-recumbent brown setae; anterior half hemelytra showing outer rim of connexiva.

Type locality. Rhagovelia umbria sp. n., was collected in the Río Guíneo, located at 0º 51 ’ 55 ” N, 76 º 34 ’ 9 ” W, 225 m, Puerto Umbría Corregimiento, Villagarzon Municipality, in the Putumayo department.

Etymology. The name “ umbria ” refers to Puerto Umbría , where the holotype was collected.

Comparative notes. The male paramere of R. umbria sp. n. is similar to that of R. callida Drake & Harris 1935 (compare Figs. 42, 43 View FIGURES 25 − 54 ), but the latter species is smaller (body L/W: 3.47 / 1.47); the hind femur is not incrassate (L/W, 7.7), versus being slightly incrassate in R. umbria (L/W, 5.5); and the male has a distinctive ventral carina in R. callida which is lacking in R. umbria .
