Etymology: Helcogramma: Greek, helkos, -eos, -ous = ulcer, sore + Greek, gramma = letter, mark (Ref. 45335); lacuna: The specific epithet is from the Latin lacuna meaning cavity, cavern, or hollow. The name refers to holes in the rocky reefs inhabited by all members of the fuscopinna complex and is treated as Noun in apposition.

Adults inhabit sand channels in patch reefs (Ref. 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
