Lohmannella grandipora Newell, 1984

Diagnosis. Corneae absent. Glp-1 anterior to Ds-1. Glps large. Ds-2 on membranous cuticle. Ds-3 on margin of PD. Two dorsal setae on PE. Female with 12–18 Pgs and 8–10 Sgs. Male with 52–73 Pgs and 8 Sgs. P-2 with 1 or 2 ventral spines. Tb I with 6 Bp ventral setae; Ta III–IV with 4-3 dorsal and 2-1 ventral setae. Lc I with partial inflation near the middle of the claw shaft and unidentate accessory process. Idiosoma length 390–456 in female, 395–425 in male. Ratio of P-2 to P-1 5.70.

Remarks. The species characteristically has a pair of large Glps on AD, OC, and PD. This character is similar to L. bispina , however, this species has longer palpi, more dosally situated Glp-2, and weaker inflation of the claw shaft than that in L. bispina . Female, male, nymphs (stages are unclear), and LV are known.

Habitat. Littoral zone: Coarse sands, shell fragments, rock crevices, under stones, kelp holdfasts.

Distribution. South Pacific Ocean: Punta Caldera (Caldera), Fuerte Bulnes, Punta Arenas [ Chile]. South Atlantic Ocean: South Georgia [ UK].
