Remarks. The genus Hexapus is characterized mostly by the narrow third maxillipeds that do not cover the buccal cavity, with the ischium narrower than the merus. To date, three species are included in this genus: H. bidentatus Velip & Rivonker, 2014 , H. timika and, H. sexpes . The most noticeable differences between these three species are in the shape of the male pleon. The male pleon of H. sexpes and H. bidentatus is narrow, with the third to fifth somites gradually narrowing, with the width of the base of the third somite 1.5 times the width of the base of the sixth somite, while in H. timika the pleon is broad, stout, third to fourth somites laterally straight, to the abruptly narrowing fifth somite with the width of the base of the third somite 1.8 times the base of the sixth somite. The fused third to fifth pleonal somites of H. sexpes is only slightly longer than the sixth somite (about 1.4 times longer, Rahayu & Ng 2014: fig. 5F), while in both H. timika and H. bidentatus , the fused third to fifth pleonal somites are clearly longer than the sixth somite (about 2 times and 1.8 length of sixth somite respectively).
Hexapus estuarinus Sankarankutty, 1975 , as a junior synonym of H. sexpes , was discussed by Ng & Rahayu (2015).
