Primary types. ♂ Lectotype: Pará, 1850 [ OUMNH]. Since the species was described by Selys based on male and female syntypes, the male redescribed by Cowley & Gloyd (1938) as holotype actually constitutes the lectotype.

Characterization. Male: Epicranium black with copper to greenish metallic reflections and a small triangular yellow spot adjacent to compound eye behind antenna, dorsum of thorax black with reddish orange spots, and dorsum of abdomen black with narrow light blue basal spots on S3–7; pale colors reddish orange, and pale yellow to yellowish blue ( Fig. 20 View Figure ). Pronotum black with large reddish orange spot on center of middle lobe. Mesepisternum black with reddish orange triangular spot on basal 3/4 to 4/5 narrowing distally, which branches at about midlength of mesepisternum into a short stripe directed posteriorly along humeral suture; mesepimeron black; metepisternum basal half pale yellow with ventral, posterior and dorsal corners black; metepimeron anterior half black and posterior half pale bluish yellow. Coxa, trochanter, and base of femur yellow, remainder of leg black; tibial spurs shorter than twice intervening spaces. Genital ligula with distal margin approximately straight to vshaped, with laterodistal corners projected ventrally, and with short lateral lobes at about midlength present to absent ( Figs. 90–92View FIGURES 85–91View FIGURES 92–96). Cercus slightly longer than S10 length, slightly shorter than paraproct, about twice as long as wide, with a depression on external dorsolateral surface, dorsal margin convex and ventral margin concave, and with a small ventrobasal blunt tooth in lateral view ( Fig. 116a View Figure ), with medial surface slightly concave, with a small blunt ventrobasal tooth, a partially membranous laminar medial lobe with tip located distal to midlength of cercus, and tip curved medially forming a subapical ridge, visible in dorsal and mediodorsal views ( Figs. 116b, c View Figure ). Paraproct longer than S10 length, at basal third narrowing to half its basal width and digitiform ( Fig. 116 View Figure ). TL 32– 38.5; Hw 16.5–18.

Female: As male but pale colors pale yellow; pronotum black with margins yellow; mesepisternum black with pale yellow narrow upper humeral stripe along basal 3/4 of suture and middorsal carina yellow; mesepimeron black with lower portion of humeral stripe along distal 1/2 to 1/3 of suture interrupted medially; pale area of S9 extended dorsally medially to about 1/3 of segment height. 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, with yellow anterior margin of lateral corner produced dorsally into a blunt tubercle (Fig. 66). TL 31.5–34.5; Hw 19–21.

Diagnosis. Protoneura tenuis  shares male cercus longer than wide and with a laminar lobe on medial surface with P. calverti  , P. klugi  , P. macintyrei  , P. scintilla  , and P. woytkowskii  ( Figs. 101 View Figure ; 107–108; 114; 116; 118). Among them, it shares male cerci and paraprocts longer than S10 length with P. calverti  and P. woytkowskii  ( Figs. 101a View Figure ; 116a; 118a), and it can be distinguished from them by the design of the orange areas on mesepisternum; in males of P. tenuis  and P. calverti  they form a triangular spot on basal portion of mespisternum narrowing distally and branching into a short stripe along humeral suture, and middorsal carina is black ( Figs. 5 View Figure ; 20), whereas in male of P. woytkowskii  they form a broad reddish orange stripe along humeral suture extending along entire length of sclerite or interrupted subapically by black, and there is an orange stripe over middorsal carina ( Figs. 22–24 View Figure ). However, in male of P. tenuis  the triangular orange spot extends along basal 3/4 to 4/5 of mesepisternum ( Fig. 20 View Figure ), and only along basal 1/2 of mesepisternum in male of P. calverti  ( Fig. 5 View Figure ). Protoneura tenuis  further differs from P. calverti  and P. woytkowskii  by genital ligula morphology, with distal segment wider than long in ectal view from flexure to tip, and laterodistal process occupying 1/3 or more of distal segment length in lateral view ( Figs. 90–92View FIGURES 85–91View FIGURES 92–96), whereas segment is longer than wide in ectal view from flexure to tip and laterodistal process occupies only 1/4 or less of distal segment length in lateral view in P. calverti  ( Fig. 75 View Figure ), and the tip of distal segment is projected distally into a long strap-like process, about as long as or longer than remainder of distal segment in P. woytkowskii  ( Figs. 94–96 View Figure ). Female of P. tenuis  shares an approximately triangular and flat mesostigmal plate with P. klugi  , P. macintyrei  , P. sulfurata  , and P. woytkowskii  (Figs. 57–58; 65; 68–70), but it can be distinguished from them by the yellow anteroexternal corner produced dorsally (Fig. 66).

Habitat and biology. This species is found along clear, slow flowing streams running over sand, silt, clay, and gravel substrates in heavy shade in Peru ( Butt 1995). In Trinidad, P. tenuis  can be found mating and guarding territories along lower, medium-gradient stretches of montane rivers where the bed is composed of sand or gravel, along bends of the river where the bedrock outcroppings allow the water to become stiller and there are overhanging Maraval lilies (Spatthiphyllum cannifolium) ( Michalski 2015).

Distribution. Trinidad, Venezuela, Suriname, Guyana, and Brazil to Peru and Bolivia ( Fig. 124 View Figure ). Assessed as Least Concern by IUCN (von Ellenrieder 2009c).
