Description

Body ground colour white. The mantle margin is bordered by a thin red outer line and an orange-yellow inner line. Rhinophores are translucent white at the base with red clubs edged in white. The branchial plumes are red with white edging on the lamellae; some individuals appear nearly all white. Maximum recorded body length is around 30 mm. It can be told from the similar Goniobranchus preciosus by the absence of a pale-blue band along the outermost mantle edge.

Distribution

Type locality: New Caledonia. Widely distributed across the Indian and western/central Pacific Oceans, with records from South Africa, Madagascar, Indonesia, Papua New Guinea, the Philippines, Japan, Midway Atoll and the Hawaiian Islands. In Japan, the 1938 monograph reported specimens from Seto, Kii Peninsula under the name Glossodoris marginata (Pease) — now treated as G. verrieri.

Etymology

The specific epithet verrieri is a patronym dedicated by Crosse 1875 to a person named Verrier.

Remarks

This species was long treated as conspecific with Doris marginata Pease, 1860 (later placed in Chromodoris and Glossodoris); WoRMS currently regards Doris marginata Pease, 1860 as a junior synonym of Goniobranchus verrieri (Crosse, 1875). The genus assignment was moved from Chromodoris to Goniobranchus in a molecular revision on molecular grounds. Soong et al. 2022 re-examined the white Goniobranchus with marginal bands using molecular data and supported the species as distinct.
