1989 ( Plate 4. 5 a-c) Procerolagena cylindrocostata Albani & Yassini, 1989, p. 381 , fig. 3D (cited from Debenay, 2013); Yassini & Jones, 1995, p. 108, figs. 289-291; Debenay, 2013, pp. 159, 289.

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: NIBRPR0000107245 .

Diagnosis. Test unilocular, elongate, slender, surface ornamented by longitudinal striae extending from basal end to middle part of neck. Short striae, about one-half of test in length, present between long striae. Wall calcareous, hyaline, and perforate. Tiny spine located at bottom center. Aperture a simple opening at the end of a slender neck.

Remarks. Our specimen has a slightly more inflated test than the specimen described from New Caledonia by Debenay (2013). This species and Lagena substriata look similar as a whole, but the spaces between striae of P. cylindrocostata is wider, the length of some striae is shorter and the basal part is more rounded than L. substriata . There are 21 extant species in the genus Procerolagena , but only one species has been reported in Korea: Procerolagena amphora (Williamson, 1848) .

Distribution. Korea, Australia, New Caledonia, Bass Strait.
