Characterization. Male: Epicranium and dorsum of thorax dark metallic copper with green reflections, dorsum of S1, distal ring on S2–5, and S6–10 black, remainder orange-brown, with a dorsal orange spot on S9 distal half; pale colors reddish orange and yellow (Fig. 17). Pronotum black with lateral corner of middle lobe orange red. Mesepisternum and mesepimeron dark metallic copper; metepisternum dark with large yellow spot on ventral half; metepimeron pale yellow with anterodorsal corner black. Coxa and trochanter dark with margins orange; remainder of leg entirely reddish orange; legs and venter of thorax pruinose; tibial spurs shorter than twice intervening spaces. Genital ligula lacking lateral lobes, with a triangularly convex distal margin and laterodistal corners of distal segment not projected ventrally (Fig. 87). Cercus about as long as S10 length and paraproct, longer than wide in lateral view, with a longitudinal split along dorsal portion of external surface, delimiting a medial sclerotized branch which ends on a broad triangular tip directed medioventrally located at about midlength of cercus (Fig. 113); remainder of cercus foliaceous, medially concave, with a small triangular tooth at ventrobasal edge, and a long, curved thick pointed tooth at mediobasal edge directed medioposteriorly. Paraproct about as long as S10 length, narrowing to half its basal width at distal 1/3, and concave medially (Fig. 113). TL 37–38.5; Hw 18– 18.5.
Female: As male but dark color black with metallic green to copper reflections, pale areas orange or yellow; pronotum black with margins yellow; legs with coxae, trochanters, and base of outer surface of femora yellow, extensor surface of femora dark brown, remainder of legs pale orange; pale lateral area of S9 extended dorsally medially to about 1/2 of segment height (Fig. 41). Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe directed dorsally, trilobed with medial lobe entire and smoothly convex (Fig. 63a). Mesostigmal plate oval with medial margin elevated and with a shallow central concavity; mesanepisterum with oblique carina arising from posteromedial corner of mesostigmal plate and ending midway to middorsal carina (Fig. 63b). TL 32.5–36; Hw 17.5–21.
Diagnosis. Male cercus morphology, with a medial sclerotized branch which ends on a tooth directed medioventrally and remainder of cercus foliaceous, medially concave, with a small triangular tooth on outer ventrobasal edge, and a long, curved thick pointed tooth at medial ventrobasal edge directed medially (Figs. 113), is shared with P. caligata, P. capillaris, P. dunklei and P. viridis (Figs. 100; 102; 106; 117). Within this group, P.
sanguinipes resembles P. dunklei by the medial sclerotized branch of male cercus ending on a broad triangular tip located at about midlength of cercus (Figs. 106; 113) and by distal margin of genital ligula triangularly convex with laterodistal corners not projected ventrally (Figs. 80; 87); in P. caligata, P. capillaris, and P. viridis the medial branch ends on a tooth directed medioventrally located at cercus tip (Figs. 100; 102; 106; 117), and distal margin of genital ligula is straight with laterodistal corners projected ventrally (Figs. 74; 76; 93). Protoneura sanguinipes differs from males of all four species by the entirely reddish orange femora, tibiae and tarsi (Fig. 17), which have various extents of dark colors in the other species (Figs. 4; 6; 21). Female can be distinguished from all congeners except P. dunklei by its trilobed posterior lobe of pronotum directed dorsally and with medial lobe entire and smoothly convex (Fig. 63a) and by the oval mesostigmal plate (Fig. 63b). It differs from P. dunklei by flexor surface of tibiae pale (Fig. 41; dark in P. dunklei, Fig. 34).
Habitat and biology. Females oviposit on sedges near banks while still in tandem with males (Westfall 1987). Distribution. Dominican Republic (Fig. 119). Assessed as Endangered by IUCN (Paulson 2009f).
