( Plate 1. 1 a-f)

Psammatodendron arborescens Norman, 1881 View in CoL in Brady, 1881, p. 404 (cited from Hayward et al., 2017).

Material examined. Korea, East Sea , station E4 (37°55 ʹ 4.816 ʺ N, 128°51 ʹ 11.786 ʺ E), 20 May 2016, by Van Veen Grab, collected by Raehyuk Jeong and Jisu Yeom. NIBR ID: NIBRPR0000107238 GoogleMaps .

Diagnosis. Wall finely agglutinated and brownish in col- or. Test free, elongated, and bifurcating. Early chamber rounded then repeatedly bifurcating tubular portion of constant diameter. Aperture multiple at the end of tubular branches.

Remarks. This is the first report of this species in Korea. Psammatodendron arborescens is the type species of the genus Psammatodendron Norman, 1881 . There are only two extant species in this genus: P. arborescens Norman, 1881 and P. indivisum Heron-Allen & Earland, 1932 . The brown colored branched chamber is the typical character of P. arborescens . Psammatodendron indivisum has a long, unbranching, narrow tubular chamber connected to a depressed circular primodal chamber, unlike the branched one in P. arborescens .

Distribution. Korea, Arctic Ocean, North Atlantic Ocean.
