Diagnosis

General shape of M. nubisa is similar to M. obscuripennis but are distinctly different in color. M. nubisa in dorsal view presents a brownish and opaque tegmen, darker toward apex, pronotum brownish and yellowish or brown legs while M. obscuripennis has a dark brown or black tegmen, brown or orange pronotum and orange legs.

Etymology

Species name refers to the light to darker coloration forming a cloudy pattern on the tegmen and is the female superlative of the latin word “nubis” which means cloudy.

Description

BODY. Length 10 mm (tegmina included), width 5 mm.

HEAD ( Figs 1A , 7B ). 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 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 slightly longer than wide with 3 times ocellus diameter in between two vertex grooves outside ocelli and 3.5 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 , 7B ), not receding and prior to anteclypeus where it bends forming obtuse angle in lateral view ( Fig. 7A ). Rostrum long, reaching but not surpassing mesocoxae. Thorax ( Figs 2A , 7A–C ). In dorsal view, pronotum with anterior concavities on each side, anterior margin of pronotum as wide as posterior margin of head including eyes, anterolateral margin curved, posterior margin grooved, postero-lateral margin slightly concave, longer than anterolateral margin, humeral angle rounded. In lateral view, pronotum curving not more than 25º ( Figs 2 , 7A ). Scutellum as long as wide with large median dimple ( Fig. 7C ). Tegmen ( Fig. 7A–C ). R bifurcates on apical half, M bifurcate on basal third, apical reticulation 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, posterior wing with 7 longitudinal veins and 5 apical cells between SC+Ra and Cup, angular protrusion of costal margin near its base present. Metafemur with apical spine in inner margin, metatibiae bearing 1 lateral spine.

MALE TERMINALIA. In lateral view, posterior margin of pygofer largely convex in middle with slight curved on last third ( Fig. 7E ). Subgenital plates ( Fig. 7F ) very long relative to height of pygofer with fine tapering appendage longer than main plate, dorsal and ventral margin of main plate straight, sterno-lateral plate present, slightly elongated. Intermediate plate present, elongated, roughly oblong shaped, linking internal sides of lateral and subgenital plates. Paramere ( Fig. 7G ) not globose, dorsal margin convex and regularly curving finishing by a sharp process pointing dorsally, ventral margin convex and largely angled subapically, apex with spiniform process pointing postero-ventrally. Aedeagus ( Fig. 7H ) with basal third of dorsal margin regularly bent without angle before the bent part, last 2 ⁄ 3 vertical and S-shaped, ventral margin regularly curved, apical extension pointing posteriorly, posterior protrusion axe-shaped with edge prolonged ventrally by a straight, long and thin extension, postero-dorsal protrusion absent.

COLOR. Head, antennae, pronotum, abdomen, legs scutellum light brown, rostrum brownish highlighted with white. Tegmen opaque light brown to brown.
