Etymology: Helcogramma: Greek, helkos, -eos, -ous = ulcer, sore + Greek, gramma = letter, mark (Ref. 45335); albimacula: The species epithet is a combination of the Latin "albus", meaning white, and "macula", meaning spot. The name refers to the pale spot on the ventral part of the pectoral fin base of preserved specimens and is treated as Noun in apposition.

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 16 - 18; شعاع نرم باله پشتي (کل) : 11 - 12; خارهاي باله مخرجي: 1; شعاع نرم باله مخرجي: 20 - 22; مهره ها: 37. A species of Helcogramma (sensu Hansen, 1986) with 2 symphysial mandibular sensory pores, second dorsal fin spines usually XIV (two of 80 specimens with XIII and 11 with XV), third dorsal fin segmented rays 10-11, last ribs on vertebral centrum 10, vertebrae modally 10+27=37, pored lateral line scales modally 19 or 20, nape scales present, males with dusky anal fin, both sexes with distinctive pale (red in life), oblong streak over lowest pectoral fin ray bases, adult males first dorsal elongate, reaching base of fourth to sixth spine of second dorsal fin when depressed (Ref. 52308).
Adults are found at depths of 5 m and shallower, in surge channels and exposed boulders (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). Minimum depth from Ref. 58018.
