This is the first record of T. robusta from Vietnam . Material examined . 3 females , 2 males , Vietnam , Cat Tien National Park , on Dipterocarpus alatus ; crown, branches at the height of 20–25 m ; 11°26′35.11′′ N 107°26′01.38′′ E ; 20.XI.2022 – 10.XII.2022 , collected by V . M. Salavatulin ; 3 females , Vietnam , Cat Tien National Park , on Dipterocarpus alatus ; crown, branches at the height of 20–25 m ; 11°26′30.60′′ N 107°25′56.15′′ E ; 20.XI.2022 – 10.XII.2022 , collected by V . M. Salavatulin . Remarks. Beron (2021) listed Tutacheyla buruensis ( Thewke, 1980 ) as a junior synonym of T. robusta . However, Corpuz-Raros (1988) separated these two species based on the number and shape of dorsal idiosomal setae. In this paper we are not accepted the synonymy of T. buruensis and T. robusta and follow the opinion of Corpuz-Raros (1988) .
