Abdominal sterna II–VI brown, darker laterally; VII mostly yellowish-brown. Terminalia dorsally black, ventrally brown. Structure. Head relatively short and wide, with erect black setae on frons; midline and two oblique basal foveae impressed and shining. Antennomere I thicker than others, slightly wider on apex, curved laterally, with seven robust erect black setae; II and III cylindrical, II with a pair of robust erect black setae; IV fusiform. Labium wide, reaching middle of mesosternum. Jugum, proepisternum, and thoracic sterna without black denticles. Pronotum without visible circular punctures, with curved lateral and posterior margins, and long black setae on sides. Mesonotum completely covered by pronotum. Metanotum short and wide. Thoracic and abdominal sterna covered by light-colored setae, more densely on sterna VII–VIII. Legs covered by short brown setae; lightercolored, thinner, long setae on coxae and trochanters; rows of long, robust, black setae on femora and tibiae. Fore tibia with weak preapical concavity ventrally and grasping comb extending slightly beyond apex. Hind trochanter with 10 black pegs and two slightly longer spines ( Fig. 2E View FIGURE 2 ). Hind femur incrassate, not surpassing apex of abdomen; basal third with 9–13 short black spines ( Fig. 2E View FIGURE 2 ); apical two-thirds with two rows of spines – dorsal row with 11 spines decreasing in size distally, ventral row with nine subequal spines. Hind tibia straight, with obtuse spinules throughout posterior surface plus a straight apical spur, without long preapical spine. Abdominal mediotergites I–VI subrectangular; I–V with a median carina; VII slightly longer than wide; dorsum of abdominal segment VIII longer than mediotergite VII. Abdominal laterotergites not elevated. Abdominal sterna II–VI with weak triangular median carina; venter of abdominal segment VIII with stronger median carina. Posterolateral margins of abdominal segment VII without black denticles.Abdominal segment VIII cylindrical, wide, covered by long brown setae. Proctiger as in Fig. 3B View FIGURE 3 . Parameres symmetrical, longer than wide, robust, wider on middle and tapering to apex ( Fig. 3D View FIGURE 3 ).

Apterous female. Color and pilosity similar to male. Proacetabulum pale-yellow; meso- and metacetabula with yellowish-brown margins. Coxae and trochanters yellow; middle trochanter darker. Femur, tibia and tarsi lighter-brown ventrally than on male. Dorsum of abdominal segment VIII centrally shiny black. Abdominal sterna centrally brown, laterally dark brown with greyish setae. Hind trochanter with three small black pegs ( Fig. 2E View FIGURE 2 ). Hind femur less incrassate than on male, with 6–7 black pegs on basal third ( Fig. 2E View FIGURE 2 ); apical two-thirds with two rows of spines – dorsal row with eight spines decreasing in size distally, ventral row with six subequal spines. Hind tibia straight, with obtuse spinules on basal third of posterior surface, without apical spur or long preapical spine. Abdominal mediotergites I–V with median carina. Abdominal laterotergites sinuous, elevated, mesally bowed adjacent to mediotergites III–IV; lateral margins with abundant brown setae, expanded adjacent to mediotergites V–VII. Abdominal sterna without median carina.

Macropterous male. Similar to apterous male in general color, pilosity, and structure. Pronotum long, brown, with a yellow spot behind eyes; posterior margin rounded. Forewing surpassing apex of abdomen, with 2 basal and 2 apical closed cells; veins brown, except yellowish laterally on lateral apical cell ( Fig. 2G View FIGURE 2 ). Small portion of abdominal laterotergites I–III visible dorsally.

Macropterous female. Similar to macropterous male in general color, pilosity, and structure. Pronotum without elevated posterior projection. All specimens with mutilated wings ( Fig. 2F View FIGURE 2 ).

Comments. Rhagovelia utria sp. nov. is part of the hirtipes group of species, based on the pronotum of the apterous form completely covering the mesonotum, the pronotum of the macropterous female without a posterior elevated projection, the abdomen of the apterous female with a median carina dorsally on mediotergites I–V, and the posterolateral margins of male abdominal segment VII surrounding the genital cavity lacking black denticles ( Polhemus 1997). So far, 12 species are included in the hirtipes group, which has a disjunct distribution from Mexico to Colombia, and also in southeastern Brazil. The only species of the group heretofore recorded from Colombia is R. femoralis Champion, 1898 , which can be distinguished from R. utria sp. nov. by the male hind tibia slightly arcuate on the basal two-thirds, with a large preapical spine; the male abdomen without a median carina dorsally; the female abdominal laterotergites lacking a mesally bowed and glabrous area adjacent to mediotergites III–V; and the male abdominal segment VIII with a low median carina ventrally ( Bacon 1956, Polhemus 1997). In R. utria sp. nov., the male hind tibia is cylindrical and lacks a large preapical spine; the male abdomen has a median carina on mediotergites I–VI; the female laterotergites III–IV are mesally bowed; and the ventral carina of the male abdominal segment VIII is stronger than on anterior segments.

Two other species of the group occur close to Colombia: R. chiriqui Polhemus, 1997 , in Panama, and R. reclusa Polhemus, 1997 , in Costa Rica. Rhagovelia chiriqui can be distinguished from R. utria sp. nov. by the goldenbrown bowed portion of the female laterotergites adjacent to mediotergites III–V and by the shape of the paramere ( Polhemus 1997: fig. 93). Rhagovelia reclusa differs from the new species by the margins of female abdominal laterotergites adjoining the mediotergites V–VII flat and covered by numerous black setae, and the male hind trochanter with seven black pegs ( Polhemus 1997). In R. utria sp. nov., the male hind trochanter has about 10 black pegs and two longer spines, the lateral portion of the female laterotergites are concolorous brown throughout the abdomen, the female abdominal laterotergites adjoining the mediotergites V–VII are expanded, and the paramere is shaped as in Fig. 3D View FIGURE 3 .

Etymology. This new species is named in honor of Utria Natural National Park, Chocó, Colombia.
