Description
Platygavialidium formosanum (Tinkham, 1936)
Eugavialidium formosanum: Tinkham 1936, Tinkham 1937.
Platygavialidium formosanum: Günther 1938a, 1941, 1955, Blackith 1992, Ichikawa 1994, Liang & Zheng 1998, Deng 2016. Gavialidium philippinum [partim]: Karny 1915.
Type material not examined. According to OSF, there are two paratypes (without defined sex) of the species deposited in Philadelphia. However, we have examined photographs from OSF and online media photographs of this species from Taiwan. Günther (1938) did not examine types of the species as well.
Type locality: R China: Taiwan: Taihoku Prefecture: Hokutō.
Notes. This species is morphologically most distant from other species of the genus. It is the only species of the genus inhabiting Taiwan, and is more slender than other species assigned to the genus. Vertex is relatively narrow, lateral ocelli, bifurcation and dorsal margins of the antennal grooves are positioned higher than in other species of the genus. VL projection is prolonged into sharp spine slightly directed forwards and the posterior lobe is reduced and rounded. ML is present as tubercles on the humeral angles, pronotal projections are lower than in other species. All the femora are elongated and bear small teeth.
