Differential diagnosis. -

L. sagittatus has, together with L. signatus and L. karwinkeli , pulvilli of the hind tarsi bearing apical teeth. Bifurcation of the frontal costa into facial carinae is close to the transverse carinae of the vertex. In L. signatus , the median carina is bent to the tip of the pronotum while in L. sagittatus and L. karwinkeli the median carina rises again in the prozona. In contrast to L. karwinkeli , the median carina of L. sagittatus is flat or weakly wavy. In frontal view, there is a right angle between lateral and transverse carina in L. karwinkeli , while in L. sagittatus the angle is rounded.

Notes. -

Günther (1937) retransferred this species to Euparatettix , with the note "although certainly related to Lamellitettigodes ". Günther wrote in 1939 (translation): "I tend to think that the real affinity [of Lamellitettigodes ] at least to Euparatettix sagittatus Bol. exists; but this species represents a true Paratettix or Euparatettix , and is to be left in these genera." L. sagittatus corresponds much better to the genus characteristics of Lamellitettigodes than those of Euparatettix or Paratettix . The carinae are clearly keeled. The prozonal carinae are the same as in L. contractus , and the tip of the fastigium is clearly protuberant in lateral view. I have examined the HT of Euparatettix pulvillus and agree with the synonymization by Günther (1937). I have not examined the type of Tetrix polypictus and was not able to check the synonymization by Günther (1937).

Specimens of L. sagittatus have variable size and coloration. Specimens from New Guinea have in frontal view less flattened fastigium than specimens from other regions. However, they belong to L. sagittatus because all other characteristics are the same.

Measurements. -

(in mm) HT: Pronotum length 11.05; pronotum lobe width 3.00; pronotum height 2.07; vertex width 0.43; eye width 0.50; tegmen length 1.50; hind wing length 11.18; postfemur length 5.20; postfemur width 1.65.
