The specimens (Fig. 9 C) probably belong to a new species related to Tenagogonus bergrothi Hungerford & Matsuda, 1958 (see Hungerford and Matsuda 1958 ), from Luzon. The genus is widespread throughout the Afrotropical, Oriental and Australian Regions, extending eastwards up to Fiji ( Damgaard et al. 2014 ). Fifteen species are known in the Malesian Region, including the Philippines ( Chen et al. 2005 ). Habitat The collected specimens were found in small forest streams, a common habitat of representatives of the genus.
