Diagnosis

M. translucida is the only species with tegmen translucid without any other coloration.

Etymology

The species name refers to the translucid tegmen and is based on the latin word “translucidus” which means allowing light to pass through.

Material examined

Holotype PHILIPPINES • ♂; “ Philippines, Camarines Sur, Luzon isl. Mt Isarog Natural Park , Panicuason Naga ”, “Muséum Paris; 1 May 2011; S.A. Yap, M.V. Yngente & O.L. Eusebio rec.”; “Muséum Paris, MNHN ( EH) 24749 ”; MNHN.

Description

BODY. Length 10 mm (tegmina included), width 4 mm.

HEAD ( Figs 1A , 11B ). In dorsal view, large ocelli, distance between eyes less than 8 times ocellus diameter, distance between ocelli equals one ocellus diameter, distance between ocellus and the compound eye 2 times ocellus diameter, ocelli closer to each other than from compound eyes. Eyes not prominent, length 1.44 times than wide. Vertex and frons longitudinal median carina absent. Vertex as long as wide with 3 times ocellus diameter in between two vertex grooves outside ocelli and 3 times ocellus diameter between anterior and posterior vertex margins. Postclypeus with longitudinal furrow, slightly swollen and ovoid shape in frontal view, widest part at mid height ( Figs 1A , 11B ), not receding and prior to anteclypeus where it bends forming right angle in lateral view ( Fig. 11A ). Rostrum long, surpassing mesocoxae. Thorax ( Figs 2A , 11 A-C). In dorsal view, pronotum with anterior concavities on each side, anterior margin as wide as posterior margin of head including eyes, anterolateral margins curved, posterior margin grooved, postero-lateral margins slightly concave, longer than anterolateral margins, humeral angle rounded. In lateral view, pronotum curving not more than 25º ( Figs 2 , 11A ) Scutellum as long as wide with large median dimple ( Fig. 11C ). Tegmen ( Fig. 11A–C ). R bifurcates on apical half, M bifurcate on basal third, apical reticulation not well developed without concave apical cells. Posterior wing ( Fig. 3A ). Rp separating from SC+Ra nearly at midlength, M reaches ambient vein, Cua and Cup fused at base and m-cu links M to Cua before Cua bifurcation, common base for Cup and Cua originate at base of wing, 7 longitudinal veins and 5 apical cells between SC+Ra and Cup, angular protrusion of costal margin near its base. Metafemur with apical spine in inner margin, metatibiae bearing 1 lateral spine.

MALE TERMINALIA. In lateral view, posterior margin of pygofer slightly undulating in the middle with slight curved on the last third ( Fig. 11E ). Subgenital plates ( Fig. 11F ) dorsal and ventral margin of main plate roughly straight, sterno-lateral plate present, slightly elongated, intermediate plate present, elongated slightly triangular shaped, linking internal sides of lateral and subgenital plates. Paramere ( Fig. 11G ) not globose, dorsal margin convex and regularly curving finishing with rounded apex with very minute groove, ventral margin convex, apex with spiniform process pointing antero-ventrally. Dorsal and ventral margins of aedeagus undulating. Aedeagus ( Fig. 11H ) with basal third of dorsal margin regularly bent without angle before the bent part and last 2 ⁄ 3 vertical and S-shaped, ventral margin regularly curved then slightly concaved before the base, apical extension sharp pointing postero-ventrally, posterior protrusion sharp at the apex hook-shaped, postero-dorsal protrusion absent.

COLOR. Head and pronotum brown with yellow patches, rostrum yellowish white, pedicel of antenna brown, legs yellowish and abdomen light brown. Tegmen partially translucid, opaque parts being yellowish with darker patches.

Type Locality

Philippines: Luzon, Camarines Sur, Mount Isarog Natural Park.

Distribution

Philippines: Luzon Island.

Remarks

The exact length of subgenital plate relative to height of pygofer is not provided because part of the appendage is damaged.
