Comments. Rhyparus helophoroides is a relatively variable species with four presently recognized synonyms. It is widely distributed, being known from Malaysia, Indonesia, Japan, Korea, Taiwan, Philippines, and New Guinea to Australia, New Caledonia and Vanuatu (Stebnicka 1998; Ochi 2001; Théry & Bordat 2012; Mencl et al. 2013; Choi & Lim 2022; Minkina & JÁkl 2024). These are the first published records for the Solomon Islands which include seven different islands: Fauro, Gizo, Guadalcanal, Kolombangara, Malaita, San Cristobal, and Vella Lavella.
