Type Material. Male holotype: [Mount Kitanglad, 25–26 May ’84, 100–150 m, S.G. Reyes], [UPLBMNH HEM 05004] (MNH-UPLB).

Paratypes. Philippines: Mindanao, Bukidnon, Mount Kitanglad, primary forest, 100–150 m asl, 26 to 26-V- 1984, S.G. Reyes, 2♂ MNHN(EH) 24381–24382 (MNHN), 2♂ UPLBMNH HEM 05003, 05005 (MNH-UPLB).

Type Locality. Philippines: Mindanao, Bukidnon, Mount Kitanglad.

Distribution. Philippines: Mindanao Island ( Fig. 148 ).

Diagnosis. P. gapudi and P. altissima have their tegmina entirely red with the exception of some apical brown to dark brown cells and their radial vein reaching the costal margin. However P. gapudi present a unique subgenital plate boomerang shaped. (Fig. 56).

Description. Body length 5.5–6 mm (incl. tegmina), width 3.5 mm Head. In dorsal view, slightly narrower than pronotum but conspicuous, distance between ocelli equals two times ocellar diameter, ocelli closer to each other than from compound eyes. Eye, 1.25 times longer than wide. Two vertex grooves extending from posterior to anterior vertex margins and forming a narrow rectangular area including ocelli, longitudinal median carina present in vertex and slightly reduced in frons. Pedicel with short and sparse hairs, flagellum with arista, short relative to pedicel. Postclypeus angular and not receding in lateral view, smooth and furrowed medially forming two narrow longitudinal carina with lateral grooves on both sides. Rostrum long, reaching middle part of metacoxae. In dorsal view, pronotum bearing 4 notches ornamented with hairs anteriorly, 2 on each side. Pronotum wider than head, finely punctuated, anterior margin curving, anterolateral margin convex and shorter than half of anterior margin, humeral angle rounded, posterior margin slightly grooved. In lateral view, pronotum convex. Scutellum as long as wide, finely punctuated,with large median depression and a tip depressed and spiniform. In lateral view, anterior margin of pronotum clearly lower than posterior margin. Tegmina ( Fig. 59 ) length 4.5–5 mm, R forking at half of tegmina length Cu and M forking in second quarter of tegmina length. Apical reticulation extending nearly to margin, apical margin very narrow. Metafemur with apical spine in inner margin, metatibiae with 1 lateral spine. Metatarsus with third segment bearing triangular subungueal process and first and second segments bearing crown of spines.

.

Male terminalia ( Fig. 54 ). In lateral view, pygofer ( Fig. 55 ) dorsal margin longer than ventral margin and almost parallel to each other, dorsal margin with small angle at 1/3 of its length, both margins almost straight posterior margin undulated and strongly convex in middle part. Subgenital plate narrowing gently up to ¾ of its length then enlarging gently toward a rounded apex, curving into a boomerang shape ( Fig. 56 ), sparse hairs essentially distributed on apical half, lateral plate roughly rectangular with part of dorsal margin truncated, intermediate plate present and leaf shaped. Paramere ( Fig. 57 ) dorsal margin curving gently in middle and without sharp angle toward apex, ventral margin gently curving 2/3 of its length then curving more strongly before last third, set of setae located on middle of dorsal margin and on ventral strongest curve, both tufts oriented dorsoposteriorly, tip of dorsal tuft not reaching posterior tip of paramere. Aedeagus ( Fig. 58 ) with dorsal margin starting with an acute angle then regularly curved, ventral margin curving first anteriorly before curving posteriorly in a large curve apical extension large and curling, narrowing gently and finishing into a round apex, posterior protrusion hook-shaped, largely curving, apex pointing ventrally, posteroventral protrusion absent.

Colour. Brownish body hairs. Head including postclypeus and rostrum light red, ocelli glassy pale red, eye pale to deep red and antennae yellowish brown. Pronotum, scutellum and tegmina bright red. Tegmina apical cells in reticulated area brown. Legs light red to deep red, tarsal claws and tip of spines black. Abdomen red.

Etymology. Dr. Victor P. Gapud was a renowned Filipino entomologist, taxonomist and a Museum Curator. He worked on the Odonata and Hemiptera . The species is named after him in honour of his great contributions in describing the Philippine Entomofauna.
