Characterization. Male: Epicranium black with copper to greenish metallic reflections, dorsum of thorax black with orange stripes, dorsum of S1–2, 9 orange, remainder of dorsum dark brown with orange basal spots on S3–8; pale colors orange and yellow (Fig. 12). Pronotum orange with black spot on center of anterior lobe, sides of middle lobe, and submedial area of posterior lobe. Mesepisternum black with broad orange stripe extending along humeral suture; mesepimeron black with small dorsal orange spot; metepisternum orange with small black spot on anteroventral corner black; metepimeron orange-yellow with a black stripe along metepisternal-metepimeral suture. Coxa, trochanter, basal 1/2 to 2/3 of femur yellow, tibia mostly yellow with some pale brown patches, and remainder of leg brown; tibial spurs shorter than twice intervening spaces. Genital ligula with distal margin approximately straight and with laterodistal corners projected ventrally (Fig. 82). Cercus slightly shorter than S10 length, slightly longer than paraproct, about twice as long as wide, with a depression on external dorsolateral surface, dorsal margin convex and ventral margin slightly concave in lateral view (Fig. 108a), with a small ventrobasal blunt tooth on outer surface; medial surface slightly concave, with a small blunt ventrobasal tooth, a partially membranous laminar medial lobe with tip located distal to midlength of cercus; tip of cercus curved medially forming a subapical oblique ridge, visible in dorsal and mediodorsal views (Figs. 108b, c). Paraproct shorter than S10 length, at basal half narrowing to half its basal width and digitiform (Fig. 108). TL 37–39.5; Hw 16.5–18.5.
Female: As male but pale colors yellow; pronotum black with lateral margins yellow; dorsum of S1–2, 8 dark brown; pale area of S9 extended dorsally medially to about 3/4 of segment height (Fig. 36). Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe entire, directed posterodorsally, with sides straight and tip smoothly convex. Mesostigmal plate approximately triangular and flat (Fig. 58), with a transverse tearshaped depression with narrowly carinate posterior margin behind mesostigmal plate. TL 32–34; Hw 18–19.5.
Diagnosis. Protoneura macintyrei shares male cercus longer than wide and with a laminar lobe on medial surface with P. calverti, P. klugi, P. scintilla, P. tenuis, and P. woytkowskii (Figs. 101b, c; 107–108b, c; 114b, c; 116b, c; 118b, c). Among them, it shares male cerci and paraprocts no longer than S10 length with P. klugi and P. scintilla (Figs. 107–108a; 114a), and it can be distinguished from them by the paraproct distinctly shorter than cercus (Fig. 108a), whereas in the other two species it is about as long as or slightly longer than cercus (Figs. 107a; 114a), and by its mostly pale tibiae (dark in P. klugi and P. scintilla) and posterior lobe of pronotum with medial 0.5 or less black (entirely black in P. klugi and P. scintilla). It further differs from them by genital ligula morphology, with distal end straight and laterodistal corners projected into ventral processes with slightly reflected tips (Fig. 82); in P. klugi tips of laterodistal processes are bifid (Fig. 81) and in P. scintilla the distal end is triangularly convex and laterodistal corners are not projected into ventral processes (Fig. 88). Female of P. macintyrei shares an approximately triangular and flat mesostigmal plate with P. klugi, P. sulfurata, P. tenuis, and P. woytkowskii (Figs. 57; 58; 66; 68–70). It can be distinguished from them by the presence of a transverse tear-shaped depression with narrowly carinate posterior margin behind mesostigmal plate (Fig. 58), absent in all other species, in which mesepisternum is either smooth (Figs. 66; 68–70) or presents a transverse carina adjacent to mesostigmal plate posterior margin (Fig. 57).
Habitat and biology. Adults found at streams and pools and seeps associated with streams.
Distribution. Western Ecuador (Fig. 125).
