(Figs. 10, 11)
Material examined. Holotype (male, Siargao 18_35): Philippines, Mindanao, Surigao del Norte, Siargao Island, Del Carmen, Brgy. Katipunan, N9.86082 E126.03313, 59.6± 5.5 m.a.s.l., 9 April 2018, 0 0 0 1 hours, coll. M.K. Tan, H. Yeo, J.B. Baroga-Barbecho, S.A. Yap (UPLBMNH).
Diagnosis. This new species differs from all known congeners by colour patterns of the tegmen and by the shape of the male cercus that is provided with a stout, bulbous, baso-internal process that bears a smaller anterior bulbous process. The presence of a baso-internal process on the male cerci similar to that of the new species occurs in only a few other species from Papua New Guinea: Salomona godeffroyi (Pictet, 1888) from which the new species differs by the frons that is rugose instead of subsmooth and the male cerci are not curved internally near apex; from Salomona karnya Willemse, 1959 it differs by the baso-internal process of the cercus being not elongated; from Salomona limbata Karny, 1907 it differs by the tenth abdominal tergite that does not have a long apical process in the middle; from Salomona megacephala (Haan, 1843), which is also similar by the presence of small lateral depressions on the tenth abdominal tergite, it differs by the absence of a distal internal process at the cerci; from Salomona solida (Walker, 1869) it differs by the frons that is not red and by the baso-internal process of the cerci that are more rounded instead of cubical and have only one anterior bulbous process instead of two; and from Salomona ustulata Redtenbacher, 1891 it differs by the rugose and yellow instead of smooth and red frons and the cerci are stouter and conical instead of elongate.
Description. Male habitus as shown in Fig. 10. Fastigium verticis in dorsal view elongated conical, apex truncate, about as long as scapus, with ocellus in middle (Fig. 11A). Vertex subrugose (Fig. 11A). Frons with large impressed dots, genae rugose (Fig. 11B). Pronotum rugose with impressed dots, disc broadly rounded into paranota, apical area subflat and shouldered (Fig. 11C); anterior margin straight but faintly concave in middle; posterior margin broadly rounded (Fig. 11A). Acoustic spiracle elongated, taller than long, completely covered by paranota. Tegmen macropterous, barely reaching abdominal apex and just as long as hind wing, apex rounded. Prosternum with two stout spines with subobtuse apices. Mesosternal and metasternal lobes conical with blunt apices. Femora with the following number of robust spines on ventral margins: anterior femur 8 external, 9 internal of increasing size distally; middle femur 7 external of increasing size distally, 3 internal at base; posterior femur 12 external of increasing size distally, 0 internal. Knee lobes of anterior and middle femora obtuse externally and long spinose internally; of posterior femur spinose on both sides. Tibiae with the following number of spines on ventral margins: anterior tibia 6 external, 6 internal; middle tibia 10 external, 8 internal.
Male. Stridulatory file on underside of left tegmen straight; about 1.89 mm long; with teeth increasingly wider and more widely spaced towards middle (compared to basal end); with circa 70 teeth (Fig. 11D). Tenth abdominal tergite depressed in middle, with one oval depression near middle on each side of depression; posterior margin prolonged into two lateral lobes with deep rounded excision in middle; posterior lobes triangular with obtuse apex (Fig. 11E). Epiproct broadly tongue-shaped, depressed in middle (Fig. 11F). Cerci conical, slightly compressed towards lateral area, internal margin straight with surface depressed, external margin curved, apex subacute; with a stout baso-internal process which is bulbous and bearing a smaller anterior bulbous process (Figs. 11E–H). Subgenital plate wider than long, apical margin deeply, narrowly and roundly excised; styli conical and very short (Fig. 11I).
Female. Unknown.
Colouration. Pale brown when alive (Fig. 10), yellow brown when preserved in ethanol. Face pale brown, fastigium verticis with a black spot ventrally, antennal socket ventrally with two black spots; scapus pale brown, pedicel pale brown with a ventral black spot, antennae yellow brown; maxillary palpus, clypeus and labrum orange, mandible black (Fig. 11B). Pronotum pale brown (Fig. 11C). Tegmen generally with cells black, most obvious in costal area (anterior area) (Fig. 11J); veins in costal area turquoise, otherwise red brown (Fig. 10). Femora and tibiae pale brown and brown respectively, with black ventral spines; tibiae with two dorsal black spots at base and before first ventral spine; stout spine of femoral knee lobe also black. Hind femur basally green, medially yellow green, distally green, knee dark red brown. Abdominal tergites pale brown; sternites very pale brown. Abdominal apex pale brown (Figs. 11E–I).
Measurements (holotype). BL 37.6; BWL 41.0; PL 10.3; PW 6.5; TL 28.8; HFL 17.9; HTL 17.5 mm.
Etymology. This species is named after the indigenous people in the southern Philippines, including Siargao Island; lumad means indigenous in Cebuano, an Austronesian language spoken in the Philippines. This species is dedicated to the Lumads.
Natural history. The new species can be found among coastal vegetation.
