Seguapallene micronesica Child, 1983: 709–711, figure 4; 1991: 145.
Material examined. Chilcott Island, 1 m, in Halimeda sp., Amphiroa sp. and rubble washings, 10–15 m, 14 September 1998, one X; Willis Reef, 15–16 m, two juveniles (coll. Diaz-Pulido).
Description. The material collected was not in good condition and it only allowed comparison with the Indo-west Pacific species Seguapallene micronesica. The specimens all have separated crurigers and a short main propodal claw, and the triangle-shaped teeth of the chelae, different from the sister species described from Lizard Island, S. crassa Child (1990: 321). The two juveniles show the same characteristics as the female.
Distribution. Seguapallene micronesica was described from the intertidal at Palau Islands, followed by a record from Guam (Child, 1991) that expanded its Pacific distribution to the north-east. This record suggests a wider distribution confined to littoral habitats of the tropical Pacific.
Remarks. This is a rare genus of six recognized species, one known from the sub-Antarctic, the others collected in Indo-Pacific localities (Child, 1991). The species is characterized by a long denticulate terminal claw and large and robust chelifores.
