Platygavialidium dentifer ( Stål, 1877)

Tettix dentifer: Stål, 1877 , Casto de Elera 1895.

Eugavialidium dentifer: Hancock 1907a , Kirby 1910, Bruner 1915.

Platygavialidium dentifer: Günther 1938a , Vanschuytbroeck 1980, Blackith 1992.

Scelimena sentiferum [misspelling]: Otte 1997.

Type material examined. 1♀ HOLOTYPE Ins. Phillipp. Leg. Semper (NHRS). The photographs of the holotype are available online in OSF.

Type locality: The Philippines (without specified locality).

Notes. Bifurcation of the frontal costa, lateral ocelli are slightly below the lower margin of the compound eyes, while antennal grooves significantly above the lower margins of the compound eyes. FL2 are produced as teeth, ML is strongly projected tooth, and behind it there is one smaller tooth. VL is strong and bilobate, anterior spine is longer and directed forwards, while the posterior lobe is rounded. Pronotal projections on the discus are recognizable. Fore, mid and hind femora are elongated and equipped with sharp teeth. A male specimen from Luzon identified by Günther (1938), of which photo is available in OSF probably does not belong to this species. It has much stronger ML plates. Further studies should determine variability within this species. P. dentifer is similar P. productum and P. kraussi . P. dentifer and P. kraussi could be synonymous with P. productum .
