Type locality. Singapore. Labrador park, forêt secondaire littorale [coastal secondary forest]

Distribution. Singapore: Labrador Park. Indonesia: Durian Is.; Java; Sumatra. Palau: Koror (new country record). Philippines: Laguna: MBG (new locality record); Quezon Province: Atimonan, Quezon National Park (new locality record), Pinaglubayan, Polillo (new locality record); Palawan: Ursula off (new locality record); Leyte: Biliran Island, Maasin (new locality record); Cebu, Moalboal (new locality record); Tawi-Tawi (new locality record); Sulu, Tapul (new locality record).

Diagnosis. This species differs from L. bitaeniatus by the yellow longitudinal band along the whole body being wider and without a ventral black lining and by male genitalia wider and shorter and without M-shaped sclerotization in the ectophallic fold (present in L. bitaeniatus ) ( Robillard & Tan, 2013). This species also differs from L. boracay sp. nov. by longitudinal lateral yellowish bands on tergites usually more distinct; black facial band between scapes thicker, broader than the antennal fossa; and pseudepiphallic parameres of male genitalia with inner lobe more triangular with more acute apex.

Habitat. The species is mostly found in secondary forests, some on river sides, and some on roadside or coastal areas ( Robillard et al., 2015). The species can be easily found resting above leaf litter and leaves. This species is active both in the day and at night but mainly sings during daytime.
