Etymology: Thysanophrys: Greek, thysanos = tassel + Greek, ophrys = eye brow (Ref. 45335).
Eponymy: There is nothing in the original description that helps, but we feel reasonably sure that this is named after the USS Chilton, which hosted the survey team led by Schultz looking at reef fish after tha Bikini Atoll (Marshall Islands) nuclear tests. (Ref. 128868), visit book page.
