Taxonomic remark Remarks on these 2 descriptions of this species are from Danny Tang (08 Oct 2020) The description of Lernanthropus sphyraenae by Chin (1948) was based on a single male specimen collected from Sphyraena japonica (common name is Japanese barracuda). Lernanthropid species are usually based on females. As you can see in the screenshot below, Chin’s drawings are substandard, and the ventral habitus appears to be based on a slide-mounted specimen. His description is just okay too. One key feature separating Lernanthropus from Lernanthropinus per Do and Ho (1985) is the endopod is considerably smaller than the exopod in leg 4 in the male in the latter genus. Subsequent descriptions of the male of some Lernanthropinustaxa, L. maajii Izawa, 2018 for example, indicate that the endopod may be entirely absent. Unfortunately, Chin’s drawing of the ventral habitus does not clearly depict leg 4 and he/she did not describe leg 4. Admittedly, leg 4 does appear to be uniramus. Sproston and Wu (1948) discussed legs 3 and 4 of L. sphyraenae but they focused on the armature/ornamentation at the tip of the presumably exopod.
The description of Lernanthropus sphyraenae by Yamaguti and Yamasu (1959) was based on two female specimens collected fromSphyraena pinguis (common name is red barracuda). Kirtisinghe (1964) reported “L. sphyraenae Yamaguti and Yamasu, 1959” from Sphyraena obtusata (common name is obtuse barracuda). Do and Ho (1985) transferred this copepod species to Lernanthropinus. Izawa (2018) provided the first description of the male (see below) based on material collected from both the Japanese barracuda and red barracuda. Unfortunately, Izawa did not discuss Chin’s (1948) L. sphyraenae. Izawa described leg 4 of the male of L. sphyraenae as uniramus. What’s also interesting is the relative lengths of legs 3 and 4 are the same between Chin’s drawing and Izawa’s drawing (but I do recognize legs 3 and 4 are broader in Chin’s drawing, but again I think the drawing was based on a slide-mounted individual). I strongly suspect Lernanthropus sphyraenae Chin, 1948 is conspecific with Lernanthropinus sphyraenae (Yamaguti and Yamasu, 1959). However,Lernanthropinus sphyraenae must be treated as valid until someone formally synonymizes it with Lernanthropus sphyraenae in a peer-reviewed publication. [details]
