DESCRIPTION.—Following characters and parts as illustrated for H. laie, new species: Female gnathopods 1 and 2, eye shape, pereopods 1–5, uropods 1, 2, 3, urosome, telson, coxae 1–4, but coxa 1 not as strongly extended forward.

Characters differing from H. laie slightly: articles 2–3 of antenna 1 equal in length to each other, female coxa 2 slightly longer.

DIFFERENTIAL CHARACTERS.—Hand and palm of gnathopod 1 slightly expanded, dactyl not reaching full length of palm and not reaching spine near softly rounded corner bearing 2 stout spines, margin near spine slightly bulging, palm otherwise setose; gnathopod 2 of terminal male with palm occupying entire posterior margin of hand, dactyl overlapping free palmar margin, younger male with shorter palm defined by two spines but not deeply recessed and lacking posterior spinule seen in H. affinis; presumed juvenile male with short oblique palm defined by 2 spines, palm shorter than posterior margin of hand, latter with 1 setule (thus juvenile male possibly that of H. affinis and not H. honoluluensis).

Eyes ruby or garnet in formaldehyde but rapidly-turning dark purple in formaldehyde or alcohol.
