Type material. -

LT Lamellitettigodes palawanicus (here designated): ♀, Philippines, N. Palawan, Binaluan, XI-XII.1913, leg. G. Boettcher, SDEI.

PLTs Lamellitettigodes palawanicus (here designated): 11♂♂, 7♀♀, Philippines, N. Palawan, Binaluan, XI-XII.1913, leg. G. Boettcher, SDEI.

Additional material examined. -

2♀♀, Philippines, N. Palawan, Binaluan, XI-XII.1913, leg. G. Boettcher, SMTD.

Differential diagnosis. -

L. palawanicus has almost parallel prozonal carinae that are slightly bent backwards. The distance between upper margin of superior ocelli and frontal margin of the fastigium, in frontal view, is significantly larger than the diameter of ocellus. The species is similar to L. contractus . L. palawanicus can be separated from the similar species by the tip of fastigium and frontal costa that are distinctly protuberant in front of the eyes and by fastigial horns that are clearly visible above the eyes.

Measurements. -

(in mm) ♀, Philippines, Binaluan ( SMTD): Pronotum length 11.96; pronotum lobe width 3.4; pronotum height 1.90; vertex width 0.50; eye width 0.45; tegmen length 1.60; hind wing length 12.74; postfemur length 6.50; postfemur width 1.95.

Distribution. -

The species is hitherto known only from Palawan (Binaluan), the Philippines.
