Primary types. Holotype ♂: Cuba [ RBINS, ex collection Guérin-Méneville ]. 

Specimens examined. 4 ♂ 4 ♀: CUBA, Sancti Spiritus Prov.  : 3 ♂ 3 ♀, Trinidad Mountains near Trinidad, small stream 7 mi N of Cienfuegos-Trinidad road {21°55' N, 80°1' W, 700 m}, 5–8 vi 1959, M.J. Westfall, Jr. leg. [ FSCA]GoogleMaps  ; 1 ♂ 1 ♀, same data but [RWG].GoogleMaps 

Characterization. Male: Epicranium and thorax, dorsum of S1–2, 10, distal portion of S3, and most of S4–9 black; pale colors reddish orange, pale blue and yellow ( Fig. 4View FIGURES 1–4). Pronotum anterior lobe black with lateral orange spots, middle lobe with dorsum orange, and posterior lobe entirely orange. Mesepisternum black with a narrow orange antehumeral stripe along basal 4/5 of sclerite; mesepimeron black with narrow orange stripe along distal 2/ 3 of mesepisternal-mesepimeral suture; metepisternum black with posterior half along basal 2/3 pale yellow; metepimeron pale yellow with anterobasal and anterodistal corners black. Coxa, trochanter, and basal half of outer surface of femur red, distal half of femur covered in bluish-white pruinescence; tibial spurs as long as or longer than twice intervening spaces. Genital ligula lacking lateral lobes and with a straight distal margin, with laterodistal corners of distal segment projected ventrally ( Fig. 74View FIGURES 71–78). Cercus shorter than S10 length, slightly shorter than 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 thick blunt tooth directed medioventrally ( Fig. 100View FIGURES 100–102); 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 longer than S10 length, at midlength narrowing to half its basal width and with tip concave medially ( Fig. 100View FIGURES 100–102). TL 40.5–43; Hw 20.5–21.

Female: As male but pale areas orange to yellow; dorsum of abdomen black except base of S3–7; middle lobe of pronotum black with yellow restricted to a lateral spot; posterior lobe of pronotum black with lateral margins only yellow; antehumeral stripe along basal 1/2 of sclerite; orange stripe along distal 1/2 of mesepisternalmesepimeral suture; legs with coxae, trochanters, and flexor surface of femora yellow; pruinescence present along sides and venter of thorax; pale lateral area of S9 extended dorsally medially to about 1/3 of segment height. Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe directed anterodorsally, lying over middle lobe of pronotum, trilobed with medial lobe constricted at base and cleft with distal corners divergent ( Figs. 50a, cView FIGURES 47–50). Mesostigmal plate enlarged and expanded into a flat foliaceous plate directed dorsally, with posterior surface concave ( Figs. 50b, dView FIGURES 47–50). TL 37–38.5; Hw 23–23.5.

Diagnosis. Tibial spurs as long as or longer than twice intervening spaces are unique for this species within Protoneura  . 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 ( Fig. 100View FIGURES 100–102), is shared with P. capillaris  , P. dunklei  , P. sanguinipes  , and P. viridis  ( Figs. 102View FIGURES 100–102; 106; 113; 117). Within this group, P. caligata  resembles P. capillaris  and P. viridis  by the medial sclerotized branch of male cercus ending on a tooth directed medioventrally located at cercus tip ( Figs. 100View FIGURES 100–102; 102; 117) and by distal margin of genital ligula straight with laterodistal corners projected ventrally ( Figs. 74View FIGURES 71–78; 76; 93); in P. dunklei  and P. sanguinipes  the medial branch ends on a broad triangular tip located at about midlength of cercus ( Figs. 106View FIGURES 106–108; 113), and distal margin of genital ligula is convex triangular with laterodistal corners not projected ventrally ( Figs. 80View FIGURES 79–84; 87). Protoneura caligata  differs from males of all four species by the bright red-orange dorsum of pronotum middle lobe, posterior lobe, and antehumeral stripe ( Fig. 4View FIGURES 1–4), which are entirely ( Figs. 10View FIGURES 9–12; 17) or almost entirely ( Figs. 6View FIGURES 5–8; 21) dark in the other four species, and by cercus shorter than paraproct and S10 ( Fig. 100View FIGURES 100–102), vs. cercus as long or longer than paraproct and S10 ( Figs. 102View FIGURES 100–102; 106; 113; 117). Female can be distinguished from all congeners by its trilobed posterior lobe of pronotum directed anteriorly and with medial lobe constricted and cleft ( Fig. 50View FIGURES 47–50); P. dunklei  , P.sanguinipes  , P. peramans  , and P.rojiza  also have a trilobed posterior lobe of pronotum directed anteriorly, but the medial lobe is entire in the first two (Fig. 63a), and bilobed but broad with smoothly convex sides in the latter two (Fig. 60b).

Habitat and biology. The habitat has been described as cold, deeply shaded mountain forest streams ( Westfall 1964a) with bed formed by sand, gravel and boulders and with pools and rapids through the water course (Lorenzo- Carballa et al. 2016). Westfall (1964a) described oviposition as occurring in tandem in moss on rocks just below the water surface. Lorenzo-Carballa et al. (2016) reported that during oviposition in tandem, the male remains in a vertical position with wings motionless or settles on the oviposition substratum, which includes stems of Cyperus  sp., Hedychium coronarium  and submerged stems of Mikania micrantha  . They also observed females ovipositing alone and occasionally submerged, either in tandem with the male or alone, and events of group oviposition with several tandem pairs ovipositing on the same substratum. The larva was described by Westfall (1964a).

Distribution. Endemic to Cuba ( Fig. 119View FIGURES 119–120), where according to Torres-Cambas et al. (2015) it is now restricted to the Guamuhaya Mountains in central Cuba. Older populations from Valle de Trinidad and Júcaro in the plains ( Gundlach 1888; Westfall 1964a) are probably extinct, as most of the plains have been deforested and transformed into sugar cane plantations or pasturelands ( Torres-Cambas et al. 2015). Assessed as Endangered by IUCN (Paulson & von Ellenrieder 2006).
