Remarks. Dana's type material is lost. Since this is the type species of Tetraloides Galil, 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 neotype be selected. The type locality 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 neotype of Tetralia nigrifrons Dana, 1852 . It was collected by J. Poupin from Acropora on 4 May 1997.
