Auricula densistriata Osada Figs 8, 9 View Figures 8–14

Lobban et al. (2012) reported A. complexa (Gregory) Cleve from Guam, but J.S. Park et al. (2018) noted that the valve size and stria density of the voucher specimens match Auricula densistriata K. Osada ( Osada 1997) . Stria density for A. complexa is 15–20 in 10 µm ( Peragallo & Peragallo 1897 – 1908), but Lobban et al. reported 26–28 in 10 µm. In SEM ( Figs 8, 9 View Figures 8–14 ) we measured 27 striae. Auricula complexa species was correctly reported from Federated States of Micronesia — Yap by Navarro & Lobban (2009) and Chuuk by Park et al. (2022) —and may well be present in Guam but we have no evidence of it, so for now remove it from the flora.
