Pothea furtadoi Gil-Santana & Costa, 2005: 400 –404 [description].

Diagnosis. Male: Total length: 18.0–21.0; COLORATION: general coloration mostly reddish, but somewhat brighter in a few specimens, with darkened or blackish markings; legs with submedian small markings on femora; variable extent and intensity of darkness on femoral apices and subbasal and apical rings on tibiae; variation also present on the corium of hemelytra, which is reddish on most extension or somewhat brighter to almost yellowish, with the area adjacent to scutellum, apex and a stripe in the central portion, brownish to blackish, and variable dark coloration (Figs.

29–30, 41, 44). Connexivum reddish, without markings (Figs. 29, 41) or yellowish, with approximately two thirds of each segment pink colored distally (Fig. 44). Blackish markings on the sternites III–VII form transverse stripes, variable in thickness, enlarged at the lateral portion, anterior extension in front of the respective spiracle in the sternites III–VI sometimes present (Fig. 32). These stripes are interrupted or incomplete in two or three segments, in which there are a median and a pair of lateral blackish markings instead of a stripe in some specimens (Figs. 42, 45–46). STRUCTURE AND VESTITURE: Head: antenna eight segmented, all segments pubescent (Fig. 31); clypeus denticulate. Thorax: integument of pronotum smooth and shiny; midlongitudinal sulcus in anterior pronotal lobe not reaching interlobar sulcus, moderately deep; midlongitudinal (in the first half of posterior lobe), transverse (interlobar) and posterolateral sulci formed by canaliculae and well developed; humeral angles rounded (Figs. 29–30, 41, 44). Legs slender, femora, particularly fore and mid, somewhat thicker, with patches of slightly long yellowish hairs on ventral face of fore and mid trochanters and femora, in the latter, they are more numerous on the basal half; in some specimens these hairs are shorter or less numerous; mid ventral fringe of short curved yellowish to orange short hairs on median portion of ventral face of all tibiae; apex of tibiae and tarsi covered with somewhat longer hairs with the same coloration; presence of a median ventral, shallow and thin crest, where the ventral fringe of hairs are inserted on fore and mid femora and all tibiae; spongy fossa well developed on pro and mid tibiae. Male genitalia (Figs. 33–40, 43, 47): pygophore subpentagonal, posterior margin sinuate; paramere apices close in resting position (Figs. 33–34). Median process of pygophore somewhat elongated, subquadrate and sclerotized (Figs. 34–35). Parameres symmetrical, curved, with a short subapical tooth, rounded at apex (Figs. 33–34, 36). Phallus with articulatory apparatus moderately short; dorsal phallothecal plate lozenge shaped, sinuous in center of anterior margin, struts enlarged at basal half and united at the apex, which is rounded (Figs. 37–39). Endosoma with a pair of lateral conjunctiva processes approximately at the median portion (Figs. 37–38). Median process of endosoma rounded, with central sclerotized structure somewhat like a “Y” (Fig. 40) or similar to a “T” (Figs. 43, 47).

Discussion. There is size and morphological differences between the males of this species. The male from the state of Maranhão, for example, has a different coloration in connexivum (Fig. 44) and is smaller in total length, being 17.1 millimeters. Variability in the dark markings of the body was also observed, particularly on the legs, with submedian small markings on femora in two specimens; variable extent and intensity of darkness on femoral apices and subbasal and apical rings on tibiae; variation also present on the corium of hemelytra, which is reddish on most extension or somewhat brighter to almost yellowish, with the area adjacent to scutellum, apex and a stripe in the central portion, brownish to blackish, and variable dark coloration (Figs. 29–30, 41, 44). However, as already described by Gil-Santana & Costa (2005), the blackish markings on the sternites III–VII form transverse stripes, with some variability in thickness, enlarged at the lateral portion, where it may have an anterior extension in front of the respective spiracle in the sternites III–VI (Fig. 32). The different portions of male genitalia were shown to be similar among the specimens examined. The shapes of the dorsal phallotecal plate and struts are particularly characteristic (Fig. 39). The median process of the endosoma in males from different states of Brazil and with very diverse coloration (Figs. 29–30, 32, 41–42, 44–46) showed minor variation (Figs. 40, 43 and 47).
