Elasmopus integer Myers, 1989

( Figs 9 , 10 )

Elasmopus integer Myers, 1989: 68 –70, figs. 5–6.— Vader & Krapp-Schickel, 2012: 1197 (key).

Material examined. Western Australia. 1 male, 5.5 mm, dissected, 4 slides, AM P.92257, Descartes Island, The Kimberley, 14°11'S, 125°40'E, 20 July 1988, coll. P.A. Hutchings, Stn 70; 2 specimens, AM P.92256, Descartes Island, The Kimberley, 14°11'S, 125°40'E, 20 July 1988, coll. P.A. Hutchings, Stn 70.

Type locality. Bora Bora, Society Islands.

Remarks. The presence of robust setae on the male gnathopod 2 basis anterodistal corner is known for Elasmopus integer , E. hooheno J.L. Barnard, 1970 , E. pseudinteger Appadoo & Myers, 2003 and E. arafura Hughes & Lowry, 2011 . Of these species, only E. integer and E. pseudinteger have an entire telson. The presence of long slender setae on the margins of the pereopods and uropod 3 rami confirm this material as E. integer and not the closely related E. pseudinteger reported from Mauritius.

The telson of specimens examined here varies slightly from the original material with a small suture along the apical margin, not illustrated in the Society Islands material.

Distribution. Pacific Ocean: Society Islands ( Myers 1989). Indian Ocean: Australia Western Australia: The Kimberley (current study).
