medusae with flattened-hemispherical to occasionally dome-shaped umbrella, with medusa buds on exumbrella, dorsally placed. A thickened and continuous marginal nematocyst ring on subumbrella; 6–11 bifid tentacles, branching proximally, with lower branch up to two times as long as upper one. Upper branch with three nematocyst clusters, one apical, and two opposite placed alternately on its aboral and oral sides. Lower branch with terminal adhesive pad. Cnidome composed of stenoteles (two size classes) and desmonemes.

Cnidome: stenoteles of two size classes, class 1 = (15.00– 17.50) × (12.50–15.00) μm, class 2 = 10.00 × 7.50 μm, and desmonemes = 7.50 × 5.00 μm, all in the upper branch, capsules restricted to both the terminal knob and the crescent-shaped clusters; no nematocysts were observed in the adhesive pad of the lower branch; marginal ring with stenoteles and desmonemes.

The third day of sampling (May 28) recorded the highest values of the measured variables and their greatest variation. The average temperature showed the highest values on the first day of sampling, ranging between 28.25 and 29.35°C.
