Siphopteron pohnpei from Pohnpei

November 25, 2003
From: Clay Carlson

Here is an example of Siphopteron pohnpei (Hoff & Carlson, 1983).

• C087_2 4.0mm; Pohnpei, Nan U (reef flat behind The Village); 6 January
2000. on the sea grass, Enhalus acoroides.

In Pohnpei and Palau we find it on Enhalus. Terry Gosliner reports it from the sand in Hawaii as does Atsushi Ono from Kerama. If someone has an idea what lives on Enhalus in warm water and on the sand in cooler water, it might give us an idea what the host may be.

Dear Clay & Patty Jo,
Thanks for this addition to the Forum. Sadly we seem to be no closer to discovering just what gastropterids eat
Best wishes
