Characterization. Male: Epicranium, thorax and abdomen brownish black with metallic green to copper reflections; pale colors orange to yellow ( Fig. 1View FIGURES 1–4). Pronotum anterior lobe entirely pale, middle lobe dark, and posterior lobe dark with lateral corners pale. Mesepisternum entirely dark, lacking pale middorsal and antehumeral stripes; remainder of pterothorax pale. Legs yellow, with extensor surface and distal end of femur brownish, and one to three diffuse brownish rings on tibia; tibial spurs shorter than twice intervening spaces. Genital ligula lacking lateral lobes and with distal margin slightly concave, with laterodistal corners projected ventrally ( Fig. 71View FIGURES 71–78). Cercus shorter than S10 length, about half as long as paraproct, about as long as wide, with a depression on external surface, dorsal margin convex and ventral margin slightly concave in lateral view ( Fig. 97aView FIGURES 97–99), with a pointed ventrobasal tooth and two dorsal teeth, an apical one on distal margin and a subapical one on medial surface, visible in dorsal and mediodorsal views ( Figs. 97b, cView FIGURES 97–99). Paraproct longer than S10 length, approximately cylindrical ( Fig. 97View FIGURES 97–99). TL 36–41; Hw 17.5–19.

Female: As male but pronotum anterior lobe with anterior margin dark, middle lobe pale, and posterior lobe pale with only posterior margin dark; pale lateral area of S9 extended dorsally medially to about 2/3 of segment height ( Fig. 25View FIGURES25–28). Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe entire, smoothly convex and directed dorsally. Mesostigmal plate approximately triangular with medial margin upright and with a central concavity; mesanepisterum forming two adjacent cylindrical tubercles lying parallel to each other between posteromedial sides of mesostigmal plates ( Fig. 47View FIGURES 47–50).

TL 36–39; Hw 20.2–21.

Diagnosis. Protoneura ailsa  and P. romanae  are the only two species with dark color on pterothorax limited to mesepisternum ( Figs. 1View FIGURES 1–4; 16; 25; 40); in all other species there are some dark areas or stripes on other sclerites of pterothorax ( Figs. 2–15View FIGURES 1–4View FIGURES 5–8View FIGURES 9–12View FIGURES 13–16; 17–24; 26–39; 41–46). They also share a similar morphology of genital ligula ( Figs. 71View FIGURES 71–78; 86), male appendages ( Figs. 97View FIGURES 97–99; 112), and female mesostigmal plates. Male of P. ailsa  differs by paraproct about twice as long as cercus ( Fig. 97aView FIGURES 97–99; clearly shorter than twice length of cercus in P. romanae  , Fig. 112aView FIGURES 112–114), and cercus apical tooth as long as subapical tooth ( Fig. 97cView FIGURES 97–99; much longer than subapical tooth located at about midlength of cercus and not distally in P. romanae  , Fig. 112cView FIGURES 112–114). Female differs by dorsum of middle lobe of pronotum pale ( Fig. 25View FIGURES25–28; dark in P. romanae  , Fig. 40View FIGURES 37–40).

Habitat and biology. Protoneura ailsa  was first discovered on a narrow stream in St. Lucia, with alternating areas of riffles and pools, bottom of gravel and sand and some emergent vegetation ( Donnelly 1961). The species occurs on small vegetated streams of sandy to rocky bottoms at 45–600 m elevation in Dominica ( Donnelly 1970; Meurgey 2008) and commonly between sea level and 400 m a.s.l. in Martinique ( Meurgey 2005), from mountain streams to small rivers in sugar cane plantations, but is absent from mangroves and flooded forests (Meurgey et al. 2008). Donnelly (1970) and Meurgey (2008) described its last larval stadium. According to Meurgey (2008), adults of this moist montane or transition forest species hang vertically on small branches or fly in shaded and heavily vegetated areas along the banks of streams and small rivers, or in nearby forested areas. They feed on small insects caught at slow areas of basins and pools. Mating takes place in the vegetation along the banks, and tandem pairs fly to a suitable oviposition site, where females lay eggs (usually still in tandem, rarely alone) in leaves, stream debris, mosses or stems of aquatic plants or roots in slow or standing waters of pools, basins, ditches or dams. Larvae emerge clinging vertically on shaded areas near the water surface (Meurgey 2008).

Distribution. Dominica, Martinique, and Saint Lucia in the Lesser Antilles ( Fig. 120View FIGURES 119–120).
