Description of male. Medium to large and chiefly black species; from the four species formerly described, this species is the only one in which males are strictly hyaline with no black morph known. The pale areas on the head are cream in immatures and turquoise or pale blue on mature individuals.

Head. Chiefly black, labrum dark glossy blue, postclypeus turquoise to pale blue, in some individuals restricted to lateral third, maxillae black or pale, frons turquoise to pale blue, in some individuals restricted to lateral edges, vertex with two pale spots anterolateral to lateral ocelli, eyes black in life; antennae black, scape can have pale line on frontal surface or be completely black with pale distal margin, pedicel with pale distal margin.

Thorax. Prothorax: chiefly black with variable pale markings on dorsum; see Fig. 120 for morphology. Pterothorax: chiefly black, usually with diffuse green metallic reflections over dark colouration on mesepisternum and mesepimeron; see Figs. 22 , 157 for colour pattern (mediodorsal carina can be pale, narrow pale line above mesopleural suture on mesepisternum can be entire, second line can be reduced to a short line of about one-fifth of the mesepimeron length starting at its posterior three-fourths, in young specimens the black mark in metepimeron reduced or absent); sternum pale; legs pale, femora with extensor surfaces and distal joints black; tibiae dark brown to black on flexor surfaces; tarsi dark brown to black; claws reddish.

Wings. Hyaline, without an apical black tip; FW with the vein that descends from the nodus from slightly proximal to slightly distal to the first post-quadrangular Vx, always closer to the first than to the second postquadrangular Vx; HW field between CuA and posterior margin with at least one supplementary vein in at least one wing; CuA in HW usually not forked, at most with one supplementary sector. Px: FW 31–41, HW 28–35.

Abdomen. Black with pale areas as follow: S1 usually with lateral or ventrolateral spots; S2 usually with ventrolateral horizontal lines, can be completely black; S3–7 usually with basolateral rings, in some males rings not completely closed on dorsum; S8 usually with basolateral spots; S9–10 and cerci pruinose on dorsum in mature individuals.

Caudal appendages. Cerci: see Figs. 62–63 for structure. Paraprocts: well-developed, forked at apex, armed with well-defined upper and lower branches.

Measurements. Abdomen: 40–48.3, FW: 34–40, HW: 33–38.

Description of female

Head. As in male.

Thorax. See Fig. 158 for colour pattern. Prothorax: see Fig. 127 for morphology.

Wings. Hyaline, with a slightly amber tint; Px: FW 33–43; Px: FW 29–38.

Abdomen. S1–7 as in male but pale markings more extensive. S8 dorsal pale spot absent. S9 pale dorsal spot mushroom shaped, widened to rear. Ovipositor ending beyond tip of cerci.

Measurements. Abdomen: 35–43, FW: 37.5–42, HW: 36.5–40.

Diagnosis. This species is closely related to P. kukulkan , P. chiarae and P. akan and is diagnosed under the latter.

Natural history. This species has been collected at small to medium-sized streams and seepages within mountain cloud forest and tropical rainforest. Found in sympatry with P. quinta at several locations. At Barranca de Metlac, Veracruz, it has been collected at seepages at vertical walls in heavily shaded microsites.

Distribution. Our original hypothesis about the restricted distribution of this species changed with time as we visited more sites in cloud forest locations. Our results show that it is more widely distributed than was originally supposed. It is presently known from east-central and southeast Mexico, widespread from the eastern part of the Trans-Mexican Volcanic Belt to the Chiapas Sierra Madre. Veracruz, Tabasco, Oaxaca and Chiapas states. It has been collected from 375–1800 m.a.s.l.

Remarks. The specimens used by Brauer to describe this species are labelled “Jalappa” and “Jalapa Cuernavaca”. The reference to Cuernavaca, located 250 km to the W, is undoubtedly an error, and the type locality is here restricted to Veracruz between Orizaba and Xalapa. The labels hold no information on when this material was collected, although we do know that Dominik Bilimek stayed in Mexico from May 1865 to June 1867 ( Bueno Bravo 2014), and thanks to correspondence published in his hometown newspaper Beilage zur Biene, we also know that he travelled and collected material on the way from Orizaba to Xalapa [sic! Chalappa] from the 11–19 May 1865 ( Bilimek 1865). This species has long been misinterpreted in the past because male dimorphism had not been suspected, so it is common to find hyaline specimens of P. quinta identified as P. hyalina as well as some of the previously undescribed species.

St. Quentin (1970) designated a lectotype, an allotypoid and a paratypoid: “Von der ursprünglichen Series liegen noch 2 ♂♂ und ein ♀ vor, von denen ein ♂ als Lectotypus, das ♀ als Allotypoid und das zweite ♂ als Paratypoid betrachtet werden. Inv.-Nr. 605. “ [“From the original series there are still 2 ♂♂ and one ♀, of which one ♂ is regarded as a lectotype, the ♀ as an allotypoid and the second ♂ as a paratypoid. Inv no. 605.”]

These designations are unjustified, since the three specimens of the type series hold the labels with the original Brauer’s designations as: Holotypus, Allotypus and Cotype [actually a paratype] ( Figs. 142–144 ).

Given that this species has been abundantly and widely collected, it is easily distinguishable. Among the material examined (n =195), no specimens with black tips on the wings were found, so it is to be considered strictly hyaline.

Recently, Y. Vega-Sánchez sent HOS pictures of Paraphlebia specimens collected in Zongolica, Veracruz; 18.6414, -96.9838 (Vega-Sánchez personal communication, October 2, 2021). They were confirmed to be P. hyalina which close the gap in between the nearest known localities: Barranca de Metlac to the north and San Bartolomé Ayautla to the south which makes finding this species in the southeast corner of Puebla state more likely.
