Lohmannella pinggi Otto, 1994

Diagnosis. One or 2 corneae present. Glp-1 posterior to Ds-1. Ds-2 on membranous cuticle. Ds-3 on membranous cuticle. Ds-4 on membranous cuticle or rarely on PD. Ds-5 absent or on PD. Two dorsal setae on PE. Female with 16–18 Pgs and 8 Sgs. Male with ca.50 Pgs and 4 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with (2,3)-3-(2,3)- (1,3) setae; Tf I–IV with (8,9)-(8,9)-6-(3,4) setae; Gn I–IV with (8,9)-(8,9)-(4,5)-(4,5) setae, 4-2-0-(1,2) Bp setae; Tb I–IV with (13,14)-(12,13)-(9,11)-(7,8) setae, 7-3-(1,2)-(3,4) Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 2-2- 4-(0,2) Bp setae. Lc I with minute multidentate (2 teeth) accessory process. Idiosoma length 278–437 in female, 382–424 in male, 374 in DN. Idiosoma width 336-349 in female, 315–319 in male, 298 in DN. Gnathosoma length 192–227 in female, 202 in male, 163 in DN. Ratio of gnathosoma to idiosoma 0.52–0.65 in female, 0.52 in male, 0.44 in DN. Ratio of P-2 to P-1 4.33.

Remarks. The characteristics of the species are: OC oblong, Glps large, Ds-1 anterior to the level of Glp- 1, Glp-3 placed near the medial magin of OC, Glp present ventrally on membranous cuticle laterad to AE, Lc with accessory process. Bartsch (2005a) collected this species from Australia and indicated several morphological differences between her specimens and original description: Ds-1 long filiform (short spiniform in Otto (1994)), 2 corneae (1 cornea) on OC, Ds-5 present (absent) on PD, and AE with 4 pairs (3 pairs) of setae. Female, male, and DN are known.

Habitat. Littoral zone: Intertidal coralline algae or tufts of algae on rocky platform.

Distribution. South Pacific Ocean: Mystery Bay, Guerilla Bay, Malua Bay (New South Wales) [ Australia]. Indian Ocean: Rickets Point (Victoria), Cape Vlamingh (Rottnest Is.), Nine Mile Beach (Esperance) [ Australia].
