Platygavialidium productum ( Walker, 1871) , comb. nov.

Tettix producta: Walker 1871 .

Gavialidium productum: Kirby 1919 , Bruner 1915, Blackith 1992.

Gavialidium philippinum: Bolívar 1887 , Hancock 1907a, Kirby 1910, Karny 1915, Bruner 1915, Günther 1938a, Günther 1939, Steinmann 1970, París 1994, Tumbrinck 2014; syn. nov.

Paramphibotettix sanguinolentus [partimm T. producta noted as synonym]: Blackith 1992.

Type material examined. 1♀ SYNTYPE ( Tettix producta ) without data (BMNH). Photographs of this syntype are available in OSF. Desipte of the lack of data on the specimen (except the type label), Walker (1871) writes in the original paper that the type comes from the Philippines, from Mr. Cuming's collection. 1♀ LECOTYPE ( Gavialidium philippinum ) Filipinas leg. Baer (MNCN). The lectotype is damaged, it lacks antennae and all the legs except the left foreleg (tarsus broken) and middle foreleg (tarsus broken as well). The photographs of the lectotype will soon be available online in OSF.

Type locality: The Philippines (without specified locality).

Notes. Lectotype of Gavialidium philippinum and Tettix producta are conspecific, the former being different only in the morphology of the posterior margin of the ventrolateral projection, what probably represents local variabiliy, thus the former is synonymized with the later ( G. philippinum syn. nov.) This species is very close in morphology to P. dentifer and P. kraussi and three species could be synonymous. The main differences this lectotype (and the series of this species from the Philippines in Bolívar's collection) are: posterior margin of the ventrolateral projection is extended and slightly bilobate at the apex, space between promedial and first metamedial projection more flat, and femora are somewhat more robust and bear stronger teeth. Interspecific variability of those species should be assessed in future. The species does not have high fastigial horns and shoulders are different in morphology. Since the species is close to P. dentifer inter-specific morphology should be examined in future between the species, as P. dentifer , P. kraussi could represent but synonyms of P. productum .
