This is the first record of Pseudobornella orientalis from the Philippines. It was known before only from Japan. The most distinctive external feature of Pseudobornella orientalis is the long slender tentacle on the rhinophoral sheaths, which can extend to at least twice the length of the body.
I 've added Baba's line drawing copied from iNaturalist.
This species was posted on 8 April 2004 at these websites as Pseudobornella orientalis  Baba, 1932,
Pola & Gosliner (2010) synonymized the genus Pseudobornella  Baba, 1932 with the genus Dendronotus  Alder & Hancock, 1845.
I noticed this change because of the recent discovery of this species at California, USA!
I changed it on 8 August 2016 into Dendronotus orientalis (Baba, 1932) [Pseudobornella].
Korshunova et al. (2020) confirm the validity of Pseudobornella  Baba, 1932, I changed it back on 26 November 2020
into Pseudobornella orientalis  Baba, 1932
