Systematics
Initial description
The first description was made by František Kovařík as part of his 2004 revision of the genus Heterometrus .
Type material
The holotype is a 78 millimeter long male, the allotype is an equally long adult female. Three subadult offspring of the allotype were identified as paratypes. The allotype and the paratypes were still alive when the species was described and were kept by Kovařík in the terrarium. The type material is in the collection of František Kovařík in Prague.
etymology
The species name honors Vladimír Šejna from Prague, who collected the type specimens. After Šejna, Kovařík named the Vietnamese scorpion Euscorpiops sejnai in 2000 and Chaerilus sejnai from Malaysia in 2005 . For these species, Šejna had also collected and provided the type specimens.
