Differential diagnosis. - L. contractus has more or less parallel prozonal carinae, slightly bent backwards. The distance between the upper margin of the superior ocelli and frontal margin of the fastigium is significantly larger than a diameter of an ocellus in frontal view. The species is similar to L. palawanicus . This species can be easily separated by the tip of fastigium and frontal costa, which are distinctly protuberant in front of the eyes, and the fastigial horns, which are clearly visible above the eyes.

Additional measurements : (in mm) ♀ Sumatra, Lac de Toba: Pronotum length 9.75; pronotum lobe width 2.95; pronotum height 2.29; vertex width 0.54; eye width 0.41; tegmen length 1.30; hind wing length 9.23; postfemur length 4.88; postfemur width 1.45. ♀, Borneo, Sepilok RDC: Pronotum length 10.79; pronotum lobe width 3.00; pronotum height 1.45; vertex width 0.47; eye width 0.45; tegmen length 1.55; hind wing length 10.27; postfemur length 4.81; postfemur width 1.60. ♂, Solomon Is., Malaita: pronotum length 9.88; pronotum lobe width 2.60; pronotum height 1.45; vertex width 0.47; eye width 0.43; tegmen length 1.35; hind wing length 8.97; postfemur length 4.42; postfemur width 1.40. Distribution. - The species inhabits the Southeast Asian mainland ( Guenther 1939 ), Singapore ( Hancock 1909 ), islands of Southeast Asia - Sumatra (and adjacent Nias, Mentawai, and Enggano), Java, Borneo, Sulawesi ( Guenther 1939 ), and finally the Solomon Islands. The species has not been found hitherto in New Guinea. Hancock (1907a) , however, refers to New Guinea under Xistra tricristata , and Guenther (1935) wrote '' (...) also known to me from SE New Guinea'' . I have not been able to detect this species in New Guinea and the Bismarck Archipelago, although it is found to inhabit the Solomon Islands. Hancock's (1907a) and Guenther's (1935) records could belong to L. novaeguineae sp. nov.
