Macromedaeus quinquedentatus

Macromedaeus quinquedentatus (Krauss, 1843) (Fig. 17G) Macromedaeus quinquedentatus Guinot 1968: 708; 1971: 1068; Serène 1968: 75; 1984: 179, fig. 104, pl. XXV D–E (for complete synonymy); Ng et al. 2008: 203 [List]. Material examined: 1 ñ, NMNS 8772-58, 5.8 × 3.9, Shanfu, Liuqiu Township, Pingtung County, 4 May 2007. Distribution: Indo-West Pacific; Hawaii (Serène 1984). Remarks: The morphology of the present specimen (Fig. 17G) aligns with the defining characteristics of M. quinquedentatus (Krauss, 1843). These features include five teeth on the anterolateral margins, a fronto-orbital width slightly less than half the greatest width of the carapace, and distinct carapace regions separated by large, deep furrows (Serène 1984: 177, pl. XXV D–E). This report marks the first record of this species from Taiwan.
