Type material. -

HT (designated as LT by Mercedes Paris 1994) Lamellitettigodes signatus  : ♀, Philippines, [Prov. Eastern Samar], Dolores, MNCN (Cat. Tipos No 123), original label from Bolívar " T. signatus  Bol." and label “Lectotipo” from Mercedes Paris.

Additional material examined. -

Indonesia: ♀, Indonesia, Ins. Buru, leg. H. Kühne, NMW.

Differential diagnosis. -

L. signatus  is unique in having median carina extended in a small flattened arch to the frontal margin of pronotum. Other characters are the shorter pronotum and hind wings, but possibly in other species there are specimens with shortened pronotum and hind wings that have not been found yet.

Measurements. -

(in mm) HT: Pronotum length 10.89; pronotum lobe width 3.00; pronotum height 2.54; vertex width 0.66; eye width 0.55; tegmen length 1.54; hind wing length 9.94; postfemur length 6.69; postfemur width 1.95.

Distribution. -

Known from the locus typicus (Dolores, Philippines) and from Buru (Maluka, Indonesia).

I identified one ♀ from Thailand (Khon Kaen, Nam Nao National Park, 24.V.1988, leg. S. Ingrisch, CJT) as Lamellitettigodes cf. signatus  , but further investigations are needed to confirm this identification.
