Zoobank registration: u r n: l s i d: z o o b a n k. o r g: a c t: A 1 7 D 4 3 F D - E F D E - 4 7 D A - B 4 1 C - 9CE5B4871DDB.

Material examined: Photographs of type material, taken by G. Giribet. Holotype, MCZ IZ-135324 (MCZ DNA105588), 30 March 2006, Isla Solarte (09 °18′ 36.6″N, 82 °13′ 01 ″W), Bocas del Toro Archipelago, Panama, collected by G. Giribet.

Sequences: From the holotype: JF293046, 18S (1772 bp); HQ856866, 28S (1863 bp); JF277749, H3 (326 bp); JF277569, 16S (449 bp); HQ848589, COI (657 bp). Determined by Andrade et al. (2012) and deposited in GenBank as Baseodiscus sp. 2 SA-2011 .

Etymology: The specific name is dedicated to the collector of the type material, Prof. Gonzalo Giribet (Harvard University), for his remarkable contribution to the systematics of not only nemerteans but also Metazoa in general.

Description: Body uniformly pale brown in colour, without any distinctive colour pattern (Fig. 2M).

Distribution: So far detected only on the Caribbean coast of Panama (present study).

Remarks: In our ML tree (Fig. 1), Baseodiscus giribeti was most closely related to B. unicolor . They differed by 5.6% in uncorrected P -distance for 16S (KF 935452, KF935459, JF277569 vs. KF935451, EF 124865) and 9.0% for COI (HQ 848589 vs. KF 935505) [KF935452 and JF277569 are from the same specimen, IZ- 135324 (MCZ DNA105588)].
