Remarks. Gonodactylaceus falcatus was first recorded from Lord Howe Island by Stephenson & McNeill (1955) and reported in detail by Ahyong (2001). The largest specimen in the present series is an adult male (TL 58 mm, AM P100916) but most specimens are juveniles. As observed by Ahyong (2001, 2012) for other specimens from Lord Howe Island and northern New Zealand, the anterior margins of the rostral plate slope posteriorly and the median carinule on abdominal somite 6 is indistinct or absent. The left side of the rostral plate in the TL 58 mm male is deformed, possibly as a result of prior injury.

Distribution. Currently attributed a wide range from Eastern Africa and the Red Sea, to Indonesia, Australia, New Caledonia, Japan, Fiji, Hawaii (introduced), French Polynesia and northern New Zealand; intertidal to less than 80 m, possibly 400 m ( Ahyong 2012).
