 Distribution. Philippines. Misamis Oriental, Mt. Empagatao.   
 Etymology. The name palaceus is an adjective which means “spade-shaped”, referring to the shape of the pseudepiphallic paramere of the male genitalia.   
 Diagnosis. The species can be recognized by its large size, black face with yellow markings below and between antennae, and by male genitalia with spade-shaped pseudepiphallic parameres and X-shaped preapical sclerites in ectophallic fold.   
 Description. Species large for the genus (Fig. 12, Table 3). Head dorsum (Fig. 20C) dark brown, with four longitudinal bands, little distinct; region posterior to eyes yellow. Fastigium dark brown to black, wider than long, with long golden setae. Scapes yellow, antennae brown, darker apically. Face including clypeus and labrum black, except posterior part, yellow to brown, with some yellow markings between and below antennae. Fronto-clypeal suture white. Mouthparts including maxillary palpi yellow to brown. Lateral face (Fig. 21C) yellowish to brownish, area posterior to eyes with a dark brown band. Dorsal disk of pronotum brown, fainter near lateral margins, with a wide median dark brown area along posterior margin. Lateral lobes of pronotum dark brown to black dorsally, ventral margin brown, with a median dark brown to black patch sometimes linked to anterior margin or to dark dorsal coloration. Fore and median legs brownish; femora with dark brown spots, tibiae with thick dark brown rings. Hind femora orange brown, with some dark brown patches on lateral edges of their inner face. Knees dark brown, tibiae and tarsi brown basally, darker apically. Hind tarsomeres with three spines on dorsal outer edge and none on outer face (n=3). Abdomen dark brown, covered with short golden brown setae. Sternites yellow brown. Cerci brown, covered with dark brown to black patches.   
 Male. FWs (Fig. 22C) not reaching abdomen mid-length. Cells yellow brown, not translucent, veins yellow brown. Angle between dorsal and lateral fields forming a whitish band including bases of and distal part of CuA (rest of CuA dark brown), bases of M, CuA/M area, and distal part of M/R area. Lateral field dark brown dorsally, lighter ventrally, with dark brown transverse veins. 1A angle wide. CuP absent. Area posterior to plectrum with a thick sclerotization. Harp wide, occupying most of dorsal field surface, with a strong transverse harp vein, poly-furcated anteriorly, forming a rounded false mirror. CuA curved inwards near apex. Mirror (d1) not differentiated. Apical field very short, with no bifurcation of CuA posterior to diagonal vein. Lateral field with six strong longitudinal veins including R, Sc, and four more ventral veins; Sc without bifurcating veins. Subgenital plate elongate, clog shaped.   
 Male genitalia (Figs. 13 A–C). Close to that of L. sanchezi. Pseudepiphallic sclerite elongate, slightly trapezoidal and convex dorsally; posterior apex with short triangular lophi, wider than long, setose, and separated by a V-shaped indentation; anterior margin straight, lateral margins slightly raised dorsally. Rami very short. Pseudepiphallic parameres spade-shaped, with a broad blade apex and a short, tapered base. Ectophallic arc complete, curved posteriorly, less sclerotized. Ectophallic fold with a longer than wide X-shaped paralleled sclerite, with a short median gap. Ectophallic apodemes very short, not reaching anterior margin of pseudepiphallus. Endophallic sclerite wide and long, translucent, its posterior apex with small, hook-like lateral expansions. Endophallic apodeme translucent or not visible.   
 Female. FWs (Fig. 23C) longer than pronotum, not overlapping. Dorsal field yellow to brown, with 6–7 strong yellow brown longitudinal veins, with dark transverse veins; posterior margin straight, slightly curved apically. Lateral field darker, with three strong and one weak longitudinal vein, with strong dark transverse veins. Ovipositor slightly shorter than hind femora, apex lanceolate, denticulate on dorsal edge. Copulatory papilla (Figs. 13D, 13E) conical and narrowed dorso-ventrally; base narrowing, triangular, convex dorsally; apex almost as wide as base, with a long lateral sclerotization forming a concave appearance.   
 Measurements (in mm). See Table 3.   
 Habitat. Unknown.
