Yap, & B.J.S. Zulueta (UPLBMNH) . Paratype (1 ♂) ( JBB030 ), same information as holotype, right mid leg for molecular analysis (L73) (MNHN-EO- ENSIF11257) .

Type locality. Philippines. Visayas: Aklan, Boracay Is., Balinghai Beach Resort .

Distribution. Philippines. Aklan, Boracay.

Etymology. The species is named after the type locality.

Diagnosis. Species close to L. bitaeniatus from which it differs by faint but wide yellowish longitudinal bands on abdomen (thinner in L. bitaeniatus ) and features of male genitalia, including shape of pseudepiphallic parameres and ectophallic apodemes longer than in L. bitaeniatus , exceeding anterior margin of pseudepiphallus.

Description. Size large for the genus ( Fig. 18 View FIGURE 18 ). Head dorsum ( Fig. 20F View FIGURE 20 ) with six wide dark brown longitudinal bands. Fastigium wider than long, setose, dark brown, apex yellow with two thin black spots on facial part almost touching each other; yellow brown, antennae brown. Epistomal suture brown (yellow in L. bitaeniatus and L. luae ). Mouthparts yellow brown, including maxillary palpi. Lateral part of head with a yellow area posterior to eye, underlined by a black band, then progressively lighter from dorsal to ventral region. Dorsal disk of pronotum slightly mottled with dark brown spots, with short black longitudinal lines on posterior apex. Lateral edges dark brown. Lateral lobes of pronotum dark brown dorsally, brown to yellow ventrally. Fore and median legs yellow brown, femora with brown spots and longitudinal patterns, tibiae with rings. Hind femora brown, with strong striated dark brown patterns on outer faces, knees black; hind tibiae brown basally darker to black apically, with yellow rings. For all pairs of legs, TaI and TaIII yellow basally, dark brown apically. Abdomen homogeneously dark brown dorsally, covered with golden setae, lateral edges with faint but wide yellowish longitudinal bands. Sclerites yellowish brown with dark brown patterns laterally. Cerci yellowish basally, with black rings near apex, ventral side black.

Male. FWs ( Fig. 22E View FIGURE 22 ) not reaching abdomen mid-length, cells and veins brown, not translucent; angle between dorsal and lateral field yellow, forming a narrow longitudinal band, including bases of CuA (rest of CuA dark brown), bases of M, CuA/M area, and half of M/R area. CuP absent. Area posterior to plectrum strongly sclerotized. Harp wide, with a longitudinal fold near angle of 1A, with 1 harp vein. Distal part of CuA straight. Mirror (d1)

not differentiated. Apical field very short, with no bifurcation of CuA posterior to diagonal vein. Lateral field dark brown, with five strong longitudinal veins including M, R, Sc and two more ventral veins.

Male genitalia ( Fig. 19 View FIGURE 19 ). Close to that of L. bitaeniatus . Pseudepiphallic sclerite trapezoidal, convex dorsally, its apex not trilobate, lophi barely individualized Rami short, half as long as pseudepiphallic sclerite. Pseudepiphallic parameres differing from that of L. bitaniatus by more rectangular shape of their posterior lobe. Ectophallic arc complete and wide. Ectophallic fold wide and triangular, with a wide M-shaped sclerotization as in L. bitaeniatus , apex membranous. Ectophallic apodemes long and parallel (longer than L. bitaeniatus ), exceeding anterior margin of pseudepiphallus. Endophallic sclerite long, exceeding anterior margin of pseudepiphallus, convex dorsally, its posterior apex with a small median triangular expansion and with short thick lateral arm.

Female (based on photograph, Fig. 18B View FIGURE 18 ). FWs nearly as long as pronotum, light brown dorsally with at least four strong dark brown longitudinal veins; posterior margin slightly curved; lateral field darker. Ovipositor slightly shorter than FIII.

Habitat. L. boracay is found in a secondary habitat on top of leaves in small plants in the garden of Balinghai Beach Resort.
