Diagnosis

Tegmen, white in basal 1 ⁄ 4 with orange marking on the basal half of the margin of the clavus. Scutellum orange with yellowish white coloration in middle. Most of vertex and frons bright yellow and postclypeus dull orange for male and bright orange for female.

Etymology

Manoborum, genitive plural made from Manobos. The Manobo tribe is found in Bongolanon, Magpet, North Cotabato.

Description

BODY LENGTH. 10.5 mm (tegmina included), width 4 mm.

HEAD ( Figs 1 , 12–13B ). In dorsal view, ocelli small, distance between eyes 10.5 times ocellus diameter ( Figs 1 , 12–13B ). Distance between ocellus and compound eye less than 3.5 times ocellus diameter (( Figs 1 , 12–13B ). Distance between ocelli 1.5 ocellus diameter ( Figs 1 , 12–13B ). Eyes not prominent, length 1.15 times than wide. Vertex with longitudinal short median carina, slightly longer than wide. Frons without any carina. Postclypeus with dimple below margin of frons and a longitudinal furrow clearly marked in male, swollen laterally and slightly ovoid shape in frontal view, widest part close to frons, not receding and prior to anteclypeus where it bends rounded in lateral view ( Figs 1B , 12–13A ). Rostrum long, reaching but not surpassing mesocoxae. Thorax ( Figs 2B , 12–13A–C ). In dorsal view, pronotum with anterior deep concavities on each side, much clearly marked in female, longitudinal median carina absent. Anterior margin of pronotum as wide as posterior margin of head including eyes, anterolateral margins curved, posterior margin grooved, postero-lateral margins slightly concave, slightly longer than anterolateral margins, humeral angle rounded. In lateral view, pronotum angle around 45º ( Figs 2B , 12–13A ), scutellum as long as wide with large median dimple ( Figs 12–13C ). Tegmen ( Figs 12–13A–C ). R bifurcates on apical half, M bifurcate on basal third, apical reticulation not well developed without concave apical cells. Posterior wing ( Fig. 13E ). 2 ⁄ 3 of M length alone then fuses with Rp before reaching ambient vein, 6 longitudinal veins on posterior wing reaching apex, four apical cells between SC+Ra and Cup, angular projection near base of costal margin present. Legs. Metafemur with apical spine in inner margin, metatibiae bearing 1 lateral spine.

MALE TERMINALIA. In lateral view, posterior margin of pygofer ( Fig. 12E ) largely convex in middle getting concave in last third and presenting a bump in first third. Subgenital plates ( Fig. 12F ) with equal length relative to height of pygofer without any appendage, regularly tapering towards apex, dorsal margin straight then curving up towards apex, ventral margin straight half its length then regularly curving dorsally, minute denticuli covering last quarter toward apex. Sterno-lateral plate present, slightly elongated. Intermediate plates present, elongated and linked with internal sides of lateral plate and subgenital plate. Paramere ( Fig. 12G ) globose, dorsal margin convex then curving regularly and finishing with a sharp spine pointed antero dorsally, lateral margin with process in middle part pointing postero-dorsally, ventral margin regularly rounded with subapical part largely protruding posteriorly then finishing with a sharp spine pointing ventrally. Aedeagus ( Fig. 12H ) with dorsal margin slightly humped at base then concave most its length, curving regularly half its length vertically and finishing ¼ its length convex in a C-shaped, apical extension pointing posteriorly, posterior protrusion thick, duck head shaped with minute denticuli along posterior margin, in posterior view basal half lobular ( Fig. 12I ), postero-dorsal protrusion absent.

COLOR. Head, and pronotum white-yellowish with orange markings, postclypeus, rostrum, abdomen and legs orange, pedicel of antennae yellowish brown, scutellum orange with yellowish white markings medially. Tegmen, translucid yellowish white, white in basal ¼ with orange marking in between white and on the basal half of the margin of the clavus, last 3 ⁄ 4 yellowish getting yellowish brown in apical fourth.
