On two new species of deep-sea carrier crabs (Crustacea, Brachyura, Homolodromiidae, Dicranodromia) from Taiwan and the Philippines, with notes on other Indo-West Pacific species

The systematics of four species of the homolodromiid genus Dicranodromia A. Milne-Edwards, 1880, from East Asia and the Philippines is reappraised: D. danielae Ng &amp; McLay, 2005, D. doederleini Ortmann, 1892, D. karubar Guinot, 1993, and D. martini Guinot, 1995; and key characters such as...
