Remarks. – Ladomedaeus Štev i, 2005, was established for an unusual species of Medaeus , M. serratus Sakai, 1965 , from Japan. A second species, L. fungillus from the Philippines, was described by Manuel-Santos & Ng (2007) based on material collected from the islands of Balicasag and Panglao. Material reported here are those that have not been listed by Manuel-Santos & Ng (2007). Live specimens are basically reddish-orange, with juveniles having a mottling of white on the carapace and chelipeds, and a more-or-less regular banded pattern of white and orange on the ambulatory legs. The fingers of the chela are brown to black throughout their entire length, but not extending into the palm. This species is known only from the Philippines.
