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: NIBRPR0000107244 GoogleMaps .

Diagnosis. Test unilocular, elliptical to ovate, compressed, initial end rounded, periphery slightly keeled. Wall calcareous, hyaline, and perforate especially near the periphery, surface transparent. Greatest width at below middle part, tapering gradually toward basal end, evenly to shoulders tapering toward terminal. Aperture terminal, oval, with a phialine lip.

Remarks. According to the original description of McCulloch (1977), L. obtecta differs from congeners in possessing numerous pores, an incomplete keel, an entosolenian tube not centered a short hyaline neck embraced in a keel, and ending in a phialine lip. There are 142 extant species in the genus Lagenosolenia , but only one species ( L. confossa ) has been reported in Korea (NIBR, 2012; Kim et al., 2016).
