Etymology. Odara , from the Yoruba language, means something good, beautiful, and useful. Gender: neutral.

Type species. Odara ori sp. n.

Diagnosis. Dorsal surface green. Corium dark brown to black with yellow veins ( Figs. 1, 3 A, C). Humeral angles tooth like and somewhat developed; apices can be covered by a black spot ( Fig. 1 A); in some species, this spot extends to the ventral surface of the humeral angles and can be bigger in ventral surface than in dorsal surface ( Figs. 1 H, 2 H). The last connexival segment is distally covered by a black stripe ( Fig. 1 A). Ventral surface of the body greenish yellow to yellow with narrow dark transversal lines ( Fig. 2 H). Metasternal process with anterior arms short and swollen ( Figs. 2 A, 4 C). Pygophore: Dorsal rim (dr) strongly excavated and covered by a dark spot concolorous with the dorsal surface of abdomen ( Fig. 4 A). Superior process of the genital cup (gp) pear-shaped ( Fig. 13 F). Parameres (pa) head in a single projection generally spearhead-shaped or blade-shaped ( Fig. 13 D, E). Ventral surface of pygophore with light stripe and smooth area below the ventral rim and stripe of deep punctures ( Fig. 4 B). Female genital plates. Valvifers VIII (v8) always covered by a big dark spot surrounding mesial borders ( Fig. 14 F). Female internal genitalia: ductus receptaculi (dre) with an oblong sclerotized swell just after expanded membranous area of the ductus and another globose adjacent to spermatheca ( Fig. 15 A-E).

Description. Head. Triangular, dorsal surface without spots (Fig. 01). Mandibular plates slightly transversely ridged, longer than tylus and contiguous in front of it, apex curved ventrally (Fig. 01). Antennal segments IV and V with more setae than the previous segments; all antennal segments dark brown to light brown or reddish. Bucculae high and rectangular, enclosing half of first rostral segment. Rostrum yellowish, setose, with black spot on the apex, forth segment inserted between anterior arms of the metasternal process ( Fig. 4 C).

Thorax. Pronotum trapezoidal, wider than long ( Fig. 1). Pronotum punctuated, except on cicatrices ( Fig. 1). Each anterolateral angle of pronotum with a small part folded, like a tooth; anterolateral margins covered with a narrow yellow stripe and transversally striate. Scutellum with punctation sparser on disc, more concentrated posterolaterally ( Fig. 3 C). Apex of scutellum acute ( Fig. 1). Corium with deep and concolorous punctation; anterolateral margin of corium yellow ( Fig. 1 A). Membrane of hemelytra light brown to dark brown ( Fig. 1). Evaporatorium green or dark brown, matte, superficially whitish, and moderately wrinkly ( Figs. 2 B, F, 14 C). Area laterad to evaporatorium elliptical or rounded ( Fig. 2 A). Peritreme ruga-like, reaching 2/3 of distance from scent gland ostiole to lateral margin of the thorax ( Fig. 3 C). Tibiae and tarsi setose. Distal margin of femora with three pairs of tiny black teeth. Legs yellowish to black ( Fig. 2 A).

Abdomen. Dorsal surface of abdomen dark brown to black. Connexivum with shallow and concolorous punctation concentrated in two lateral excavations; these excavations can be dark-colored. Outer lateral margin of segments with distal tiny black tooth. Ventral surface with medial line elevated ( Fig. 2 C). Spiracles elliptical on calloused yellow areas. One trichobothrium in line with spiracles and the other laterad.

Male. Pygophore trapezoidal in dorsal view with somewhat developed posterolateral angles ( Fig. 4 A). Dorsal rim generally leaving the superior process of the genital cup visible in dorsal view; coarse and setulose. Laterals of dorsal rim fused to posterolateral angles ( Fig. 4 B). Superior process of the genital cup black to dark brown, flattened, medially concave, subtriangular ( Fig. 13 F). Genital cup shallow with tufts of setae at the base of the parameres and close to superior process of genital cup ( Fig. 4 D). Parameres swollen, with a rounded base; inner face of parameres light brown and coarse, outer face yellowish and striate; parameres always covering the superior process of the genital cup in posterior view ( Fig. 13 D, E). Ventral surface of pygophore with light stripe and smooth area below the ventral rim and stripe of deep punctures ( Fig. 4 B). Proctiger (pc) excavated laterally ( Fig. 4 D), excavation covered by sparse setae; dorsal face smooth and shiny delimited caudally by swollen carina and shorter than posterior face ( Fig. 6 D); posterior face subtriangular or pentagonal, covered or not by sparse setae, wrinkly, and ventrally directed in some species ( Fig. 4 D). Phallus. Phallotheca arched, short, about twice longer than wide ( Fig. 4 G). Vesica elliptical ( Fig. 4 G).

Female. Valvifers VIII medially excavated, generally punctate and setose ( Fig. 14 F); contiguous or not, leaving part of the valvulae VIII visible ( Fig. 4 F); slightly projected over the basis of laterotergites IX (la9). Valvifers IX (v9) trapezoidal and excavated at base ( Fig. 14 F). Laterotergites VIII distally with a black spine; surpassing the level of the seventh abdominal segment ( Fig. 4 F). Laterotergites IX excavated at base and surpassing tergite uniting laterotergites VIII. Internal genitalia ( Fig. 15 A-E). Valvulae IX with three barely sclerotized areas. Proximal and distal apices of the vesicular area of the ductus receptaculi barely sclerotized. Thickening of vaginal intima with distal part wider than proximal part. Anterior annular flange around a swollen part of the ductus receptaculi and narrower then posterior annular flange. Basal half of pars intermedialis esclerotized. Globose distal part of capsula seminalis small, about the same width of pars intermedialis.

Comments. Odara gen. n. can be easily recognized by the dorsal coloration green, humeral angles tooth-like generally with black apices, corium dark brown to black with yellow veins, the spearhead shape of parameres, and the sclerotized swelling of the ductus receptaculi in the female internal genitalia. The taxonomic and cladistics relationships are discussed here based on preliminary results of a cladistics analysis of all Edessinae genera including Odara gen. n. that will be published soon (Campos et al. in prep.). This genus was recovered as monophyletic with four synapomorphies: the spearhead shape of parameres; the two-lobed superior process of the genital cup; the clear stripes on the ventral surface of pygophore; and the sclerotized swelling of the ductus receptaculi. The swelling of the ductus receptaculi is similar to Olbia and Anisoedessa . In Odara gen. n. the swelling is restricted to the portion close to the spermatheca, while in Olbia the whole duct is sclerotized and swollen and Anisoedessa has the sclerotized swelling restricted to the portion before the anterior annular crest. The sister-group of the genus is the clade composed by Hypoxys and Pygoda supported by one characteristic of the female internal genitalia: the spherical shape of the sclerotized swelling close to the anterior annular crest. In general, specimens of Odara gen. n. resembles those of Hypoxys in size, color, punctuation, shape of humeral angles, and connexivum covered with black stripes. But, the corium of Odara gen. n. is dark brown to black with a few yellow veins, while the corium of Hypoxys is brown variegated with yellow; the ductus receptaculi of Odara gen. n. has a distinctive swelling that Hypoxys does not have; the parameres of Odara gen. n. have a unique spearhead shape, never present in Hypoxys ; the pygophore of Hypoxys is barrel shaped, in Odara gen. n. is trapezoidal; the lateral margin of evaporatorium of Odara gen. n. is rounded or ellipctical, in Hypoxys this margin is deeply excavated in “V”. Odara gen. n. species are very different from Pygoda : smaller size, shallower punctation, without black coloration on dorsal surface of the body, corium with few veins.
