03E9DD6D997B6766FEB72B71FC137D9F.taxon	description	Thorax. Legs: Forelegs with long fine setae on femur, and hard spatulate setae of varied sizes, long fine setae on tibiae and tarsi, other short setae as in Fig. 13. Midlegs and hindlegs similar to forelegs, but with spatulate setae on hind tibiae (Figs. 14, 15). Tarsal claws (Fig. 16) with small subequal denticles, without large subapical denticle. Hind wingpads present. Abdomen. Posterolateral spines on segments 2 to 9, those on 7 to 9 progressively larger. Gills on segments 1 to 7; gills slender, with main tracheae visible without ramifications, minute setae on margins of gills (Fig. 20). The new genus can be distinguished from other genera of Atalophlebiinae by the following combination of characters: clypeus slightly divergent with sinuous margin; labrum with shallow emargination and three non­prominent denticles; maxillary palp very large and curved with setae in varied combinations; labial palp very long and curved, with long setae; paraglossae wider than long; abdominal posterolateral spines gradually longer posteriorly.

03E9DD6D997B6766FEB72B71FC137D9F.taxon	etymology	Etymology: Segesta is a goddess of harvests; the name refers to shape of the maxillary and labial palps, that recalls sickles used in harvesting.	en	Siegloch, Ana E., Polegatto, Cleber M., Froehlich, Claudio G.

03E9DD6D99796763FEB72F4BFDAC790E.taxon	description	Head. Dorsum of head orange­brown, with a narrow transverse dark brown band between ocelli extending to anterior base of eyes. Mouthparts: orange­brown, lighter in ventral surface; cardo and base of mandibles darker. Labrum (Fig. 1): dorsal row of about 50 long fine setae, very close to anterior margin; a group of about 9 dorsal curved setae on each half. Mandibles as in figures 3 – 6. Maxillae (Figs. 7 – 9): Cardo with about 6 short setae; stipes with minute basal posterior prominence on outer margin; anterior margin of galealacinia completely occupied by hard brush of setae; in ventral anteromedian area, about 15 pectinate setae, with apical comb, and one large pectinate setae with complete comb (Fig. 9). Hypopharynx as in Fig. 10. Labium as in Fig. 11. Thorax. Dorsum of thorax orange­brown with dark spots at anterior and posterolateral margins of pronotum, and at the base of fore wingpad. Pronotum with row of about 8 spine­like setae on anterolateral margin. Legs: Orange­brown, dorsal surface of coxae with small dark spots; ventral surface of fore femora with two basal gray spots and two other apical; ventral surface of middle and hind femora with an apical gray spot. Forelegs (Fig. 13) with long fine setae on posterior margin of femora, and hard spatulate setae of various sizes, ca. 6 long, and ca. 14 short; short setae on anterior margin of femora and short spatulate setae on dorsal surface; long fine setae on posterior margin of tibiae and tarsi, and short spine­like setae on anterior margin of tibiae and tarsi; midlegs (Fig. 14) similar to forelegs, but femora with ca. 8 long and ca. 3 short spatulate setae on femora; hindlegs (Fig. 15) similar to those described before, but femora with ca. 8 long and ca. 14 short spatulate setae, and spatulate setae also on tibiae, ca. 6 long and 8 short. Tarsal claws (Fig. 16) with small subequal denticles, about 6 apical and 6 basal; a big subapical denticle absent; apical denticle curved. Abdomen. Gray spotted, as in Fig. 17. Margin of tergum 5 as in Fig. 19. Shape of caudal filaments as in Fig. 18. Nymph, mature, male. Eye. Lower portion black, upper portion orange­brown. Body length 6,3 mm.
