Anoplodelphys corneci Lafargue and Laubier, 1978

Material examined: Holotype female, reg. no. ZMA CO.102.603. Two females in Monniot collection, from Didemnum maculosum (Milne Edwards, 1841) collected at Dinard, France; reg. no. MNHN-Cp2319.

Differential diagnosis: Body vermiform with indistinct segmentation. Cephalosome with narrow frontal margin bearing rostrum ventrally. Rostrum inflated, forming simple lobe, without accessory median lobe. Post-rostral median lobe absent. Labrum inflated, forming elongate tapering lobe. Lateral margin of cephalosome expanded ventrally to form ridge-like swelling produced into process at posterior end. Adjacent antennomedial lobe drawn out into long posterior process. Metasome elongate with about 20% of length extending posterior to origin of leg 4: metasomal somites bearing legs ventrally near lateral margins. No mid-ventral processes present between legs. Urosome vestigial; located terminally, with median anal incision; bearing partly incorporated caudal rami armed with setae distally.

Antennule unsegmented with setose apex. Antenna reduced, 2-segmented, with triangular basal segment and distal subchela incorporating sclerotised distal claw, armed with 2 vestigial setal elements. Mandible to maxilliped lacking. Legs 1–4 biramous; each comprising short basal part (derived from protopod), largely incorporated into somite, carrying unsegmented, lobate rami. Leg 5 not observed.

Body length of female 0.85–3.90 mm. Male unknown.

Remarks: Examination of the holotype of A. corneci (ZMA CO.102.603) confirmed the original description in every respect. The new material comes from the same host species, Didemnum maculosum , collected in the same region. This species is readily characterised by the small size and simple structure of the rostrum (about the same width as the base of the labrum) and by the distribution of legs 1–4 along the metasome.
