Dana's typematerial is lost. Since this is the typespecies of  TetraloidesGalil, 1986, and there is the possibility that it may be confused with species like  T. muta( Linnaeus, 1758)(see discussion for that species), it is best that a neotypebe selected. The typelocality is Pukapuka Island(= Honden Island) in the Tuamotu Archipelago, French Polynesia( Dana, 1852: 263). A male (MNHN­B 25322; cl 8.2 mm, cw 8.9 mm; Plate 2B) from Fangataufa Atoll (22° 11.3S, 138° 45.1W), Tuamotu Archipelago, is herein designated as the neotypeof  Tetralia nigrifrons Dana, 1852. It was collected by J. Poupin from  Acroporaon 4 May 1997.
