Rhagovelia tricoma sp. n.

Type material. HOLOTYPE, apt M, allotype apt F: COLOMBIA, Nariño, Tumaco, Resguardo indígena Awá, Saundé, 1º 30’ 12” N, 78º 20’ 12” W, 300−350 m, 19−23 I 1996, leg. D. N. Padilla ( ICN). PARATYPES, same data as holotype: 1 apt M (PSO-CZ); Nariño, Barbacoas, El Diviso, Quebrada El Verde, 23 VI 2011, leg. D. N. Padilla, 1 apt M, 1 macr M ( ICN); 1 apt M (PSO-CZ).

Color and pilosity. General color dark brown; abdominal sternite VII, genital segments, outer rim of connexiva, greater part of antennae, and legs shining black; rostrum shining brown. Anterior transverse band of pronotum, basal 1/5 of first antennal segment; coxae and trochanters of fore and hid legs, yellow. Venter dull brown. Dorsal body covered with abundant, long, semi-recumbent, black setae and bright black denticles. Vertex with one pair of dark setae; antennal segment I bearing five long, 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 4.33; maximum width 1.32. Length of antennal segments I −IV: 1.02, 0.64, 0.72, 0.66; pronotum shorter than the length of head (0.18/0.36), L/W: 0.18/1.24; length of exposed mesonotum 0.76; length of exposed metanotum at midline 0.08.

All trochanters unarmed. Anterior tibia slightly dilated and slightly flattened on ventral surface. Posterior femur slightly increased, ventral surface in distal half with a row of five spines, beginning with a sharp, slender, forward-angling tooth and decreasing in size distally, proximal (largest) spine (0.2); hind femur reaches the apex of abdomen; hind tibia straight, with a longitudinal row of six small, black pegs along 1/3 basal, with two apical teeth and a moderate-length, black, apical spur.

Proportions of male legs as follows: fore femur/tibia/ tarsal 2/ tarsal 3: 1.08/1.36/0.1/0.30; middle femur, length/ tibia/ tarsal 1/tarsal 2/tarsal 3: 1.68/1.40/0.08/0.66/0.86; hind femur length-width/ tibia/ tarsal 1/tarsal 2/ tarsal 3: 1.44−0.36/1.60/0.06/0.14/0.32.

Median length of abdominal tergites as follows: I: 0.14, II −IV: 0.16, V: 0.20, VI: 0.24, VII: 0.38, VIII: 0.44; connexiva angled upward at 30º. Venter slightly convex, lacking longitudinal medial carina , sternite VII>VI>V (0.32, 0.22, 0.16, respectively), genital segments well developed, proctiger ( Fig. 8 ), parameres (L/W: 0.18/0.06, Fig. 34 ).

Apteorus female. Length 4.60, maximum width 1.44. Length of antennal segments I −IV: 1.04, 0.70, 0.72, 0.42. Posterior femur, ventral surface in distal half with a row of four spines, reaching apex of abdomen, L/W: 1.6/ 0.34; hind tibia similar to apterous male; tergites IV −VI slightly depressed, connexiva angled upward at 50º. Abdomen L/W: 2.0/1.4. Median length of abdominal tergites as follows: I: 0.16, II and IV: 0.20, III: 0.24, V: 0.26, VI and VIII: 0.30, VII: 0.38; tergite VIII inclined downward 30º; basal width of tergite VII: 0.32; proctiger vertical ( Fig. 65 ). Venter, sternite VII>VI>V (0.50, 0.32, 0.28, respectively); gonocoxa slightly visible.

Macropterous male. Length 4.86, maximum width 1.52. Similar in general coloration to apterous male, with following exceptions: pronotum brown, with anterior band yellow and posterior margin covered with scattered, long, semi-recumbent, black setae; humeral angles prominent and rounded, apex broadly rounded; L/W: 1.42/1.52; hemelytra exceeding (0.70) tip of abdomen, bearing 3 closed cells, 2 long cells originating in the basal portion of the wing followed by one smaller cell, displaying uniformly dull brown, darker veins; Sc and R+M+Cu veins covered with short, semi-recumbent black setae.

Macropterous female. Length 5.4, maximum width 1.68. Similar to winged male in general structure and coloration with following exceptions: pronotum length/width 1.64/1.68; hind femur less increased and with 1+4 spines.

Type locality. Rhagovelia tricoma sp. n., was collected at Saundé.

Etymology. Tricoma , a greek noun meaning “hairy”, refers to dorsal body of the male which bears abundant long setae, and the male proctiger which also possesses numerous setae.

Comparative notes. The paramere of Rhagovelia tricoma sp. n. is similar to that of R. rosensis Padilla-Gil 2010 (compare Figs. 34, 35 ), however R. tricoma may be distinguished by hind femur bearing a row of five spines, and the characteristic proctiger shape with long setae on the posterolateral margin ( Fig. 8 ). In R. rosensis the hind femur bears 9−10 spines and the proctiger lacks setae on the posterolateral margin ( Fig. 9 ).
