In addition, one larval sample was collected from the same region and identified as likely Ichthyophis biangularis using genetic methods.[4] DescriptionThe holotype of Ichthyophis biangularis measures {{convert|258|mm|abbr=on}} in total length, including {{convert|5.8|mm|abbr=on}} long tail. The body is {{convert|9.8|mm|abbr=on}} wide and blackish slate above and below with a yellow lateral line. The eye is dimly distinct, with a slightly lighter ring about it.[2] HabitatThis is a little known species. It is presumed to inhabit tropical moist forests.[1] References1. ^1 {{Cite journal | author = Inger, R. | author2 = Iskandar, D. | author3 = Das, I. | author4 = Stuebing, R. | author5 = Lakim, M. | author6 = Yambun, P. | author7 = Mumpuni, Wilkinson | author8 = M., Gower, D. | author9 = Kupfer, A. | last-author-amp = yes | title = Ichthyophis biangularis | journal = The IUCN Red List of Threatened Species | volume = 2004 | page = e.T59612A11968412 | publisher = IUCN | date = 2004 | url = http://www.iucnredlist.org/details/59612/0 | doi = 10.2305/IUCN.UK.2004.RLTS.T59612A11968412.en | access-date = 10 January 2018}} {{Taxonbar|from=Q1934727}}2. ^1 {{cite journal |last1=Taylor |first1=E.
