Type Locality. Philippines: Visayas, Negros Occidental, Mount Kanlaon   .

Distribution. Philippines: Visayas, Negros Island ( Fig. 148 View FIGURES 148 ).

Diagnosis. The coloration pattern of the tegmina of P. conica   clearly allows distinguishing it from all the other species. Only P. rufolimbata   ( Figs 127–130 View FIGURES 127–131 ) can eventually be mistaken. However, when P. conica   , has tegmina black with a regular deep red band along the costal margin, P. rufolimbata   , presents a brown tegmina with a larger and less regular red band along the costal margin.

Description. Body length 7–8 mm (including tegmina), width 4 mm.

Head. In dorsal view, slightly narrower than pronotum and concealed in the pronotum, distance between ocelli equals two time ocellar diameter, ocelli closer to each other than from compound eyes. Eyes, 1.26 times longer than wide. Vertex with grooves outside ocelli, extending from posterior to anterior margin and delineating a narrow rectangular area. Frons with carina. Antennal 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. Pronotum wider than head and finely punctuated, bearing 4 dorsal notches, 2 on each side, and ornamented with hairs; anterior margin curving, anterolateral margin convex and smaller than half of anterior margin, posterolateral angle rounded, posterior margin slightly grooved. Pronotum convex in lateral view ( Fig. 28 View FIGURES 26–29 ). Scutellum finely punctuated, as long as wide, with tip depressed and pointed and with large median depression. Tegmina ( Fig. 35 View FIGURES 30–35 ) length 6.5–7.5 mm, R bifurcating after middle half, Cu and M forking in ¼ of tegmina length. Apical reticulation slightly reduced, not reaching apical margin. Metafemur with apical spine in inner margin, metatibiae with 1 lateral spine, third segment of metatarsus bearing a triangular subungueal process, first and second segments bearing an apical crown of spines.

Male terminalia ( Fig. 30 View FIGURES 30–35 ). In lateral view, pygofer ( Fig. 31 View FIGURES 30–35 ) with dorsal margin longer than ventral margin, concave on posterior half and convex on anterior half, ventral margin straight and oblique, posterior margin slightly concave. Subgenital plate with dorsal margin concave basally then almost straight except for tip curving abruptly down, ventral margin basal half convex then almost straight except for tip curving up, apex of subgenital plate spiniform ( Fig. 32 View FIGURES 30–35 ), hairs only in basal half. lateral plate roughly leaf shape, pointing ventrally and bearing setae on dorsal margin, intermediate plate present. Paramere ( Fig. 33 View FIGURES 30–35 ) with dorsal and ventral margin largely rounded in middle, dorsal margin slightly concave subapically, with set of long setae located on roundest dorsal and ventral area and oriented dorso posteriorly, tip of dorsal tuft reaching posterior tip of paramere. Posterior tip of paramere with two spiniform processes located dorsally and ventrally.Aedeagus ( Fig. 34 View FIGURES 30–35 ) with dorsal margin presenting drastic curves up to middle then gently convex toward apical extension, ventral margin curving down, making a small break before being almost straight on a small portion then curving up, apical extension curling broadly with apex not sharp, posterior protrusion roughly conical, posteroventral protrusion present. Anterior part of ventral margin curving down strongly then making a small break before being almost straight 1/3 of its length.

Colour. Head, including postclypeus and rostrum, deep red, ocelli glassy pale red, eyes white with red marks, antennae yellowish brown. Pronotum, and scutellum blackish-red, brownish hairs in the pronotum notches. Tegmina mostly black except for few brown apical cells and a red costal margin. Legs deep red, tarsal claws and tip of spines black. Abdomen red.

Etymology. The species has a unique character in the male genitalia with the aedeagus bearing a cone-shaped posterior protrusion. The species name refers to this shape with the Latin feminine adjective “ conica   ”.
