Type locality: Bocas del Toro, Panama.

External morphology. Ircinia with a thickly encrusting growth habit and a forest green external surface color. Sometimes possesses lobate, short branches departing from base ( Figure 2 View FIGURE 2 ). Conules small (1.5–2 mm in height), sometimes of lighter color than the rest of the body. The body is dotted with black oscula that are uniform in size (0.4–0.5 cm diameter) and are either slightly elevated or flushed to the surface.

Interior morphology. Primary fascicular fibers 80–200 µm wide, cored. Interconnecting fibers 20–60 um wide, nearly uncored to completely uncored ( Figure 3 View FIGURE 3 ). Irciniid filaments 1–4 µm wide, terminating in spherical knobs 6–10 µm in diameter.

Ecology. All specimens were collected from shallow depths (0.4–0.5 m) on patch reefs that occur in association with small seagrass beds.

Etymology. This species is named for the immunologist Jun Siong Low for his methodological advances in identifying pan-coronavirus antibodies.

Remarks. Tissue takes on a slightly crisper consistency when preserved in ethanol for several days. Referred to as the ‘Encrusting’ growth form in Kelly et al. (2021).
