Etymology. Named flinti /ˈflɪnti/ (L. noun genitive), after the late Dr. Oliver Simeon Flint Jr., renowned world expert on caddisflies and avid Odonata collector who first discovered this species.

Description of holotype

Head. Chiefly black, labrum dark glossy blue; postclypeus pale blue; frons pale blue; vertex with two pale spots anterolateral to lateral ocelli; occiput with complete pale occipital bar; eyes dark brown to black, black in life; antennal scape with pale spots on distal margin; pedicel pale on distal 0.3; flagellum first segment pale, distal segments black.

Thorax. Prothorax: chiefly black; continuous pale stripe on lateral edges from anterior to posterior lobe, this pale area widening medially on posterior half of middle lobe, medial pale longitudinal stripe on anterior and middle lobe ending at posterior margin of middle lobe, these two stripes connected by dim line along suture between middle and posterior lobes; see Figs. 103 View FIGURES 95–104 , 105 View FIGURES 105–116 for morphology. Pterothorax: chiefly black with diffuse green metallic reflections over dark colouration on mesepisternum and mesepimeron; see Fig. 20 View FIGURES 20–27 for colour pattern; sternum pale; femora light brown becoming black distally; tibiae brown; tarsi dark brown; claws reddish.

Wings. Hyaline, slightly tinted amber; FW with one post-quadrangular cell, the vein that descends from the subnodus at the first post-quadrangular Vx; CuA in HW not forked, field between CuA and posterior margin with one supplementary vein on right wing. Px: FW 34/34, HW 31/31.

Abdomen. Black with pale areas as follow: S1 with a transverse basal line that does not reach ventral carina; S2 with ventrolateral horizontal lines; S3–7 with basolateral spots; base of cerci pruinose on dorsum.

Caudal appendages. Cerci: see Fig. 78 View FIGURES 73–78 for morphology. Paraprocts: well-developed, clearly forked at apex, with well-defined upper and lower branches.

Measurements. Abdomen: 38, FW: 37, HW: 35.

Variation in males.

Measurements. Abdomen: 41–42, FW: 36–37, HW: 35–36; Px: FW 30–35; Px: HW 26–29.

Description of female. Female unknown.

Diagnosis. Paraphlebia flinti belongs to a characteristic group of species with erect lateral edges on the posterior lobe of the prothorax which includes P. kinich and P. hunnal . ( Figs. 98–99, 103 View FIGURES 95–104 ). Paraphlebia flinti appears more closely related to P. kinich , as the particular morphology of their prothorax singles them out from all other species ( Figs. 105–106 View FIGURES 105–116 ). Both species present corniform projections on the laterodorsal corners of the posterior margin and can be differentiated by their shape, in P. flinti their tips are directed dorsally and are higher than the medial section of the posterior margin ( Fig. 105 View FIGURES 105–116 ), while in P. kinich they are directed laterally and are lower than the medial section of the posterior margin ( Fig. 106 View FIGURES 105–116 ). The main character separating P. hunnal from P. flinti and P. kinich is the convex posterior margin of the posterior lobe, the lobe seeming trifoliate in dorsal view instead of with dorsolateral corniform projections ( Figs. 98 View FIGURES 95–104 , 107 View FIGURES 105–116 ). The shape of the paraprocts also sets these species apart; in P. flinti they are clearly forked, with well-developed upper and lower branches ( Fig. 96 View FIGURES 95–104 ), while in P hunnal the inferior lobe is small and pointed at the rear with a shallow groove possibly indicating the presence of a superior lobe ( Fig. 89 View FIGURES 85–94 ). Finally, in P. kinich the paraproct is reduced to a single somewhat angled lobe, the posterior margin lacking any projection ( Fig. 86 View FIGURES 85–94 ).

Natural history. This species has been found on medium-sized streams (1–2 m wide) within pine-oak forest. To our knowledge this is the only species inhabiting streams in terrestrial habitats other than tropical rainforests or montane cloud forests.

Distribution. Southeast Mexico: known only from two locations in the municipality of Jitotol in Chiapas from 1630–1700 m.a.s.l.
