Material examined. – 1 male, cl 7.5 mm, ZRC, River outside Inabacan Cave , Antequrra, coll. Y. Cai et al., 16 Dec.2000 ; 1 male, cl 10.5 mm, 1 female, cl 10.0 mm, ZRC, Loboc River , Loboc, coll. Y. Cai et al., 19 Dec.2000 .

Remarks. – Marcobrachium equidens is a brackish water species, with gravid females and smaller specimens being commonly found in mangrove creeks. It is known from a very wide area in the Indo-West Pacific, from Madagascar to the Solomon Islands and Fiji ( Choy, 1984; Chace & Bruce, 1993; Short, 2004). However, a recent molecular analysis results ( Liu et al., 2007) show that the incongruence of non-monophyly of M. equidens , in 16S, COI and 16S+COI analyses, implied the existence of a cryptic species in the Philippines and Taiwan.
