Diagnosis This species of Yoda has the proboscis, collar, and genital wings with a deep brownish purple color, which continues with fading intensity along the posterior body. Neck ridges and nuchal protuberances are absent. The collar has extremely wide, non-tapered lips. The posthepatic intestine, in the last third of the body, shows a marked sinuosity. Adults are simultaneous hermaphrodites. [details]Etymology Latin masculine genitive noun demiankoopi. The name commemorates Dr. Demian Koop of the University of Sydney, a passionate developmental biologist and exceptional scientist whose very untimely death in 2021 has been keenly felt by his friends and colleagues all over the world.

Remark Yoda demiankoopi n. sp. can clearly be distinguished from Yoda purpurata because the former has (1) extremely wide, nontapered lips; (2) a mid-dorsal connective tissue bulge running along the hepatic and posthepatic regions of the intestine; and (3) a sinuous posthepatic intestine. However, the sister group to Yoda demiankoopi n. sp., shown on Figure 2A as Yoda “B sp. 2,” also does have extremely wide, non-tapered lips and the sinuosity of the posthepatic intestine (see fig. 1h in Osborn et al., 2013). These two can be distinguished visually in life because Yoda “B sp. 2” lacks the deep brownish purple color anteriorly that characterizes Yoda demiankoopi n. sp. Yoda demiankoopi n. sp., and Yoda “B sp. 2” do not particularly resemble the Star Wars character named Yoda, unlike the type species Yoda purpurata, but the close relationship phylogenetically allows us to apply the name Yoda more generally. There is no information on the morphology of the sister group to Yoda purpurata, shown in Figure 2A as IFREMER Yoda. [details]
