Lanicola Hartmann-Schröder, 1986 , emended

Lanicola Hartmann-Schröder, 1986: 58 ; Hutchings & Glasby 1988: 24.

Paraeupolymnia Young & Kritzler, 1987: 687 –689; Londoño-Mesa 2006: 23 , 24. New synonymy. Type species. Lanicola lobata Hartmann-Schröder, 1986 by original designation.

Diagnosis. Two pairs of branched branchiae on segments 2 and 3. Seventeen pairs of notopodia from segment 4, notochaetae smooth-tipped capillaries. Nephridial papillae on segments 3, 4, 6 and 7. Neuropodia from segment 5, uncini arranged in double rows face to face on segments 11–20. Lateral lobes present on segment 3.

Remarks. When the genus Paraeupolymnia was described in 1987 the differences between this genus and Eupolymnia were commented on, but it was not compared with Lanicola , a genus described only one year before. Lanicola was described as having lateral lobes on segment 3 ( Hartmann-Schröder 1986, Hutchings & Glasby 1988) and Paraeupolymnia on segment 2 ( Young & Kritzler 1987). Londoño-Mesa (2006) emended the genus Paraeupolymnia by adding to the diagnosis the characters of lateral lappets shared by segment 2 (ventrally) and 3 (dorsally) and ventrally connected to the first ventral shield. Study of L. lobata type material has revealed that the lateral lobe emerges ventrally from segment 2 is fused to segment 3 on its dorsal margin, as in Paraeupolymnia . Londoño-Mesa (2006) also included in the diagnosis of Paraeupolymnia the presence of ventral pads, occurrence of notopodia from segment 4 and uncini in single rows on segments 5–10. These and the rest of characters previously reported for both genera are the same in both genera and so they are considered synonymous. Lanicola has remained monotypic until now, but with Paraeupolymnia as a junior synonym and the description of two new species, the number of species in the genus increases to four, namely L. lobata described from Australia, L. carus ( Young & Kritzler, 1987) and L. garciagomezi ( Londono-Mesa, 2006) from the Caribbean, and L guillermoi sp. nov. and L. eduardoi sp. nov. from the Panamanian Pacific. The diagnosis of Lanicola is expanded to incorporate features shared by all its species such as the position of the lateral lobes and also the presence of nephridial papillae on segments 3, 4, 6 and 7.
