Terebellidae (Polychaeta: Terebellida) from the Grand Caribbean region 2320 Author Londoño-Mesa, Mario H. text Zootaxa 2009 2009-12-22 2320 1 1 93 https://biotaxa.org/Zootaxa/article/view/zootaxa.2320.1.1 journal article 10.11646/zootaxa.2320.1.1 1175­5334 5316176 Lysilla Malmgren, 1866 Malmgren, 1866:392–393 .— Hutchings & Glasby, 1986:325 .— Hartmann-Schröder, 1996:523 . Type species: Lysilla loveni Malmgren, 1866 , by monotypy. Diagnosis: Tentacular membrane expanded, trilobed, wide; eyespots and lateral lappets absent; small midventral shields; six to 12 thoracic segments; notopodia from segment 3, notochaetae smooth, hirsute or pinnate; abdominal notopodia and notochaetae absent; thoracic and abdominal neuropodia and neurochaeta absent. Remarks: Only one species has been described for the Western Atlantic Ocean, Lysilla alba Webster, 1879 , from Virginia . Londoño-Mesa and Carrera-Parra (2005) reported an undescribed species, Lysilla sp. from the Mexican Caribbean ; nevertheless, this species was not named because it was only one specimen in poor condition. Herein, I report an additional specimen in better condition; it is named as Lysilla caribe sp. nov. being the only species described from the Grand Caribbean region.
