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.
