Material examined: 2 ò 2 ñ (including 1 ovigerous individual), NMNS 8772-55–56, 2.9–4.8 × 1.7–2.6, Shadao, Hengchun Township, Pingtung County, coll. H.- T. Hung, 17 October, 2020.

Distribution: Christmas Island ( Australia), Amami-Oshima Island ( Japan); Gilbert Island; southern Taiwan.

Remarks: The genus Lioxanthodes is a small group of xanthid crabs represented by only three species: Lioxanthodes alcocki Calman, 1909 ( Christmas Island, Australia), L. madagascariensis Serène, 1984 ( Madagascar), and L. pacificus Edmondson, 1935 (Washington Island, Kiribati). This study documents the first record of this genus from Taiwan. The morphology of the specimens examined ( Fig. 17D, E View Fig ) closely matches the description of L. alcocki Calman, 1909 ( Calman 1909: 706–708, pl. LXXII, figs. 1–3; Serène 1984: 202, fig. 124, pl. XXX A). One female specimen from this study carried 28 eggs with an average diameter 0.49 ± 0.14 mm (n = 5) preserved in alcohol. This species marks the first report of this species in Taiwan.
