Lumbricalus Frame, 1992

Type species. Lumbriconereis januarii Grube, 1878

Diagnosis. Prostomium without antennae, without eyes; notopodia slightly developed; without branchiae; simple and composite multidentate hooded hooks present, composite spinigers present; pygidium with anal cirri; maxillary apparatus with five pairs of maxillae, carriers as long as MI, joined to entire base of MI; MI forceps-like without internal accessory teeth, with attachment lamella; MII shorter than MI, with ligament, narrow attachment lamella along 2/3 of posterior lateral edge; wide strongly sclerotized connecting plates; MIII completely pigmented, wide attachment lamella along entire posterior lateral edge; MIV completely pigmented, wide attachment lamella; MV free, reduced to attachment lamella, lateral to MIV and MIII. Mandible fused up to 3/4 of its length.

Remarks. Frame (1992) characterized the genus by the presence of composite spinigers, in addition to composite multidentate hooded hooks usually present, but without a complete description of the maxillary apparatus. Carrera-Parra (2004) redefined the genus on the basis of the maxillary apparatus and noted the presence of MII shorter than MI and a wide connecting plate.
