Buenoa prosthetus View in CoL n. sp.

Type material. HOLOTYPE, macr ♂ , allotype macr ♀: COLOMBIA, Nariño, Tumaco, Finca Mar Agrícola , Universidad de Nariño , 0–3 m, 20 November 2008, leg. D. Padilla, ( ICN) . PARATYPES, same data as holotype, of these the following have been distributed: 1 ♂, 3 ( ICN) , 2 ♂, 4 ♀ ( PSO-CZ) , 1 ♂, 3 ♀ ( CP) . All macropterous.

Description. Macropterous form. Dimensions. Length M 8.0, F 8.53; greatest body width M 1.72, F 1.9. Width of head M and F, 1.62.

Color of overall body bright white, dark eyes. Abdominal dorsum white with irregular areas of black and with a yellow apex. Abdominal venter black except for keel and portions of connexivum, these white. Median longitudinal axis of head, pronotum, and hemelytra covered by thin, long, transparent setae, but membrane not covered by setae. Female differs from male because she has yellowish connexivum and abdominal dorsum, and with black laterotergites IV–VI.

Male structural characteristics: As viewed from above, outline of head rounded with anterior margin of vertex continuous with that of eyes; greatest width of head approximately six times anterior width of vertex (1.62/0.26) and less than humeral width of pronotum; synthlipsis approximately four times anterior width of vertex (0.26/0.06); along median longitudinal axis, head half of length of pronotum; tylus slightly inflated, with abundant setae; labrum’s width bigger than its length and with a tuft of hair. Rostral prong ( Fig. 5 View FIGURE 5 a) almost equal or sometimes longer than third rostral segment, this originating near half of third rostral segment, and with pointed apex. Pronotum tricarinate, lateral margins light divergent; posterior margin convex, medially concave; humeral width approximately 1.4 times its median length (1.20/1.68), and slightly longer than scutellum (1.2/1.04). Fore femur thickened at apex, stridulatory area consisting of approximately five weak ridges ( Fig. 5 View FIGURE 5 b). Fore tibia with stridulatory comb consisting of approximately 23 teeth ( Fig. 5 View FIGURE 5 c), 10 of them short and straight, followed by 8 inclined, and then 5 irregular ones. Fore and middle legs with a preapical structure of tarsus (see Fig. 3 View FIGURE 3 e). Distinct male genital claspers ( Figs. 5 View FIGURE 5 d–e). Spine from caudosinistral margin, slightly curved and very narrow in distal half.

Female structural characteristics: ovipositor with teeth arranged in two longitudinal rows ( Fig. 5 View FIGURE 5 f), and hind femur with 27 spines along posterior margin. Other non sexual characteristics as in male.

Etymology: Prosthetus . A Greek adjective meaning “special,” referring to the distinctive characteristics of this species, apparently more specialized (see discussion).

Comparative notes: Buenoa prosthetus is characterized by the width of head 1.62, a very narrow synthlipsis (0.06), a stridulatory comb of the fore tibia with irregular disposition of the teeth, and a unique shape of male genital claspers ( Figs. 5 View FIGURE 5 d–e).
