Genus Laubieriellus Maciolek, 1981 View in CoL
Type species. Prionospio salzi Laubier, 1970 .
Description (emended from Maciolek, 1981b). Prostomium anteriorly rounded, or with slight medial incision, extended posteriorly as a caruncle, occipital tentacle absent. Peristomium distinct from chaetiger 1, partly fused to prostomium. Four pairs of branchiae from chaetiger 2; branchiae elongate, cylindrical, smooth and distinct from notopodial lamellae. Neuropodial lamellae connected by ventral crests from chaetiger 2. Post-branchial notopodial lamellae connected in dorsal crests. Anterior chaetae all capillaries, multidentate hooded hooks present in posterior neuropodia. Notopodial hooks absent. Pygidium with 2 short ventrolateral lobes and 1 dorsomedial cirrus, or 3 subequal lobes or an undifferentiated ring.
Remarks. The new species described here is accommodated by the description of Maciolek (1981b) except that Laubieriellus cacatua sp. nov. has a smooth pygidial ring, with no pygidial lobes and no dorsomedial cirrus. We have therefore modified the generic diagnosis.
