Max. size: Basal diameter 15 mm; height 9 mm; orifice width 6 mm.

Shell: Balanus reticulatus, grows together with crowded populations of Balanus kondakovi and Balanus amphitrite, and therefore takes an irregular tubular shape. In tubular forms the orifice was comparatively larger and more distinctly toothed. Radii usually narrow with oblique summits and alae with oblique summits. Sheath solid with lower margin slightly overhanging. Parietal tubes were about 11-19 in single row in rostrum with thin transverse septa.
Opercular valves: The upper part of the inner surface of the scutum generally smooth. Henry and McLaughlin (1975) observed it to be moderately roughened. End of the spur both in Balanus reticulatus and Balanus variegatus was described as obliquely truncate (Henry and McLaughlin, 1975). However, at times Balanus reticulatus had obliquely truncated spur but Balanus variegatus was with bluntly pointed spur.
Mouth parts – Labrum: Utinomi (1967) observed three teeth on either side of the notch. Henry and McLaughlin (1975) observed 0-5 (3.8) teeth on crest on each side of notch; usually with one tooth on each side on crest near notch.
Inner maxilla: According to Southward (1975) the lower corner of maxilla I was prominent compared to Balanus amphitrite amphitrite. Henry and McLaughlin (1975) observed this character was highly variable from slight to strong.
