The first zoeal stage of Harrovia albolineata Adams and White, 1848 (Crustacea: Brachyura: Pilumnidae), with a note on Eumedonine systematics

The first zoeal stage of Harrovia albolineata Adams and White, 1848 (subfamily Eumedoninae) is described. The zoea has a preponderance of pilumnid rather than parthenopid characters, and supports recent views that the Eumedoninae should be transferred from the Parthenopidae to the Pilumnidae. This zoeal stage is compared with those of Echinoecus pentagonus, the only other eumedonine whose larval development is known, and differs mainly in the structure of its abdomen and carapace. The status of the subfamily Eumedoninae is also briefly discussed.
