Etymology: Lethenteron: Etymology not explained, perhaps lethalis (L.), lethal, or lethe (Gr.), forgetting or forgetfulness; enteron (Gr.) intestine, presumably referring to “degenerate and non-functional” intestine of adult L. appendix. (See ETYFish);  appendix: Latin for appendage, referring to “thread-like appendix” (genital papilla) on anterior portion of nuptial males (DeKay believed this papilla was appended to the anal fin). (See ETYFish).

Issue
This species’ nomenclatural history is very complex and over the years authors have used a variety of names for it (see Creaser and Hubbs, 1922, Hubbs and Trautman, 1937, Chute et al., 1948, Bailey, 1980, Vladykov and Kott, 1982a, 1982b). The specific name used here reflects a stable use over the last 25 years or so (Ref. 89241).
