Tetraloides nigrifrons (Dana, 1852) (Plate 2B)

Tetralia nigrifrons Dana, 1852: 83, pl. 16, figs. 2a (colour)—d.

Tetralia nigrifrons forma lissodactyla Serène & Dat, 1957: 283, pl. 1.

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.
