Diagnosis. Dorsal shield with two (three?) pairs of glandularia, gnathosoma attached to a protrusible tube.
Description. Male: Idiosoma dorsally 535 long and 446 wide, ventrally 591 long. Integument lineated, brownish. Dorsal shield 454 long and 352 long, with two pairs of glandularia and the postocularia. However, as the dorsal shield is not fully developed yet, very likely three pairs of glandularia will be incorporated. Dorsal furrow with five pairs of glandularia.
Gnathosomal bay with a medial cleft, gnathosoma attached to a protrusible tube. CxI medially fused, Medial margin of CxIII straight, Cxgl4 on CxIII near suture line of CxIII/IV. Anterior to insertions of fourth legs a ridge. Genital field with three pairs of acetabula. Gonopore 98
long, nearly as long as genital field. Length of P15: 24, 76, 66, 104, 44. P2 ventrally with a short seta, P4 ventrally with a very small setal tubercle. Length of Ileg46: 88, 110, 128 (till tip of segment). Length of IVleg46: 109, 121, 130; seta of IVleg6 62 long. Fourth leg with numerous stout setae. Excretory pore not incorporated in ventral shield.
Female: Unknown.
Etymology. Named after the town of Moana at Lake Brunner.
Remarks. The male of
L. auspexa
has three pairs of glandularia on the dorsal shield too (assuming that fullygrown
L. moanaensis
has a dorsal shield with the same number of glandularia), but the gnathosoma of
L. auspexa
is not attached to a protrusable tube, the acetabula are elongated and narrow and a ridge is lacking anterior to the insertions of the fourth legs.
