Characterization. Male: Epicranium and dorsum of thorax black with metallic purple reflections, abdomen black except for very narrow basal pale orange ring and middorsal hair thin longitudinal stripe on S3–7 and pair of small dorsolateral orange spots on S9; pale colors reddish orange, orange and yellow ( Fig. 10View FIGURES 9–12). Pronotum black with lateral margin of middle lobe orange. Mesepisternum and mesepimeron black; metepisternum black with large orange to yellow spot on ventral half; metepimeron pale yellow with anterior and dorsal margins black. Coxa and trochanter black with margins orange, basal 5/6 of outer surface of femur black, distal 1/6 of femur and outer surface of tibia orange-red; 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. 80View FIGURES 79–84). 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. 106View FIGURES 106–108); 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. 106View FIGURES 106–108). TL 41–43; Hw 20–22.

Female: As male but black color with metallic green to copper reflections, pale areas yellow; pronotum black with margins yellow; with a yellow spot on anterodorsal edge of mesepimeron and metepimeron; legs with coxae, trochanters, and base of outer surface of femora yellow, most of femora dark brown, tibiae pale brown; pale lateral area of S9 extended dorsally medially to about 1/3 of segment height ( Fig. 34View FIGURES 33–36). Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe directed dorsally, trilobed with medial lobe entire and smoothly convex. 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. 56). TL 38–38.5; Hw 21.5–22.5.

Diagnosis. Male cercus, 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 ( Fig. 106View FIGURES 106–108), is shared with P. caligata  , P. capillaris  , P. sanguinipes  , and P. viridis  ( Figs. 100View FIGURES 100–102; 102; 113; 117). Within this group, P. dunklei  resembles P. sanguinipes  by the medial sclerotized branch of male cercus ending on a broad triangular tip located at about midlength of cercus ( Figs. 106View FIGURES 106–108; 113) and by distal margin of genital ligula triangularly convex with laterodistal corners not projected ventrally ( Figs. 80View FIGURES 79–84; 87); in P. caligata  , P. capillaris  , and P. viridis  the medial branch ends on a tooth directed medioventrally located at cercus tip ( Figs. 100View FIGURES 100–102; 102; 117), and distal margin of genital ligula is straight with laterodistal corners projected ventrally ( Figs. 74View FIGURES 71–78; 76; 93). Protoneura dunklei  differs from males of all four species by the black basal half of femora outer surface ( Fig. 10View FIGURES 9–12), which is pale in the other species ( Figs. 4View FIGURES 1–4; 6; 17; 21). Female can be distinguished from all congeners except P. sanguinipes  by its trilobed posterior lobe of pronotum directed dorsally and with medial lobe entire and smoothly convex (as in Fig. 63a) and by oval mesostigmal plate (Figs. 56; 63b). It differs by flexor surface of tibiae dark ( Fig. 34View FIGURES 33–36; pale in P. sanguinipes  , Fig. 41View FIGURES 41–44).

Habitat and biology. Seepage headwaters of small, forested montane streams, where males perch about 3 m from the ground on tips of leaves and branches of shrubs located in sunny openings along densely shaded streamsides, and tandem pairs hover over muddy masses of fibrous roots near water’s edge ( Daigle 1990).

Distribution. Dominican Republic ( Fig. 119View FIGURES 119–120). Assessed as Least concern by IUCN ( Paulson 2009e).
