Description
Summary:Lohmannella subfalcata Bartsch, 2003 Diagnosis. Two corneae present. Ds-2 on membranous cuticle. Ds-3 on membranous cuticle. Two dorsal setae on PE. Female with 43–45 Pgs and 8 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with (3,4)-(3,4)-(2,3)-2 setae; Tf I–IV with 6-6-(5–7)-5 setae; Gn I–IV with 7-7-5-5 setae, 3-0-0-0 Bp setae; Tb I–IV with 11-10-(7,8)-7 setae, 6-3-0-2 Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 2-1-2-1 Bp setae. Lc I almost smooth, with a trace of accessory process. Idiosoma length 295–314 in female, 244 in DN, 150 in LV. Idiosoma width 254 in female. Gnathosoma length 260 in female, 187 in DN, 95 in LV. Gnathosoma width 96–100 in female. Ratio of gnathosoma to idiosoma 0.80 in female. Ratio of P-2 to P-1 4.30. Remarks. This species is similar to L. falcata in general aspects, however, distinguishable from the latter by the round shape of PD, the short distance between the anterior margin of GO and that of GA, and Ta III–IV with 4-3 dorsal setae. The species recorded under the name of L. falcata from Josephine Seamount by Bartsch (1973a, b) will be equivalent to this species (Bartsch 2003b). Female, DN, and LV are known. Habitat. Bathyal zone: Sediment at 318–332 m depth. Distribution. North Atlantic Ocean: Great Meteor Seamount. References. Bartsch (1973a, b, 1975, 2009a, 2003b). Depository. ZIZMH.
