Description

Reticulidia halgerda grows to a maximum length of 7.0 cm.[3] This species is different externally and internally from species in the Phyllidia and Phyllidiopsis genera, both of which also have yellow coloration and tuberculate ridges. Reticulidia halgerda does not have spiculose tubercles but instead has reticulate ridges on the notum that are smooth. Phyllidia ocellata, Phyllidia tula, Phyllidia varicosa, and Phyllidia coelestis all have a different foregut as well as tubercles capped with yellow coloration. Furthermore, unlike Reticulidia fungia, Reticulidia halgerda does not possess a broad bluish white border.[4]

Distribution

This species is found in numerous locations in the central and western Pacific Ocean, including East Australia, Taiwan, the Philippines, Indonesia, the Marshall Islands, and Fiji.[5][3]
