21. Lagena striata var. semiornata Reuss, 1863 View in CoL

( Plate 4. 4 a-c)

Lagena striata var. semiornata Reuss, 1863 p. 341 View in CoL , pl. 3, fig. 45 (cited from Ellis and Messina, 1940).

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: NIBRPR0000107243 .

Diagnosis. Test unilocular, fusiform, with short basal spine. Surface ornamented by distinct longitudinal striae about one-half in length of test. Basal portion of neck irregularly costate. Wall calcareous, hyaline, and perforate. Aperture terminal at the end of neck with a phialine lip slightly costate.

Remarks. Our specimen has a very unusual striae pattern that continues from the bottom of the test to the middle part of the test and reappears throughout the neck. This specimen is different from the original description in having additional striae on the neck, and currently L. striata var. semiornata is regarded as a fossil species. This specimen is most closely related to L. striata var. semiornata , however the specimen has to be reallocated to an extant species in the near future.

Distribution. Korea, Germany.
