Siphopteron brunneomarginatum is rare in the Marshalls, or perhaps just not often found due to its small size. We have found three specimens, one at Enewetak and four at Kwajalein Atolls. All were under rocks at depths of 10 to 15 meters on either lagoon pinnacles or seaward reefs. The largest measured 6mm in length. Christina Sylvester has seen numerous specimens exposed in a shallow reef quarry at Kwajalein Island.
Below is the Enewetak Atoll specimen.
