Wallacidia retinula : Lo Cascio 2015: 564; Okayasu et al. 2018: 307, ♀; Pagliano et al. 2020: 295; Boutin & Vilhelmsen 2024: supplementary table S2, S3, ♀.

Material examined. 1♀. Vietnam: VINH PHUC: Melinh , 21°23'N 105°42'E, alt. 56 m, 20.VII.2010, J. Kantoh leg. [1♀ ELKU] .

Identification source. Compared with types [ TARI] .

Previous record. None.

Distribution. China. Taiwan. Vietnam *: Vinh Phuc.

Occurrence in Vietnam. July. South China-Vietnam subtropical evergreen forests ecoregion. 56 m alt.

Sex association. Male unknown. Lelej (2005) suggested that this species could be the female of Wallacidia conversa ( Chen, 1957) , presumably because Wa. conversa and Wa. retinula are the only species of the genus occurring in China and Taiwan aside from Wa. oculata .

Remarks. This species was described based on seven females from China and Taiwan ( Chen 1957). The Vietnamese female was compared with the type specimens, and no noticeable variation was observed.
