Material examined. Holotype male, Hapiata Stream , interstitial, Okiwi Bay, South Island, New Zealand, 41°06.167 ′ S 173°40.763 ′ E, alt. ± 50 m asl, 28ii2020 ( NMNZ). GoogleMaps
Diagnosis. Dorsum with eight pairs of glandularia, six of these on the dorsal shield. CxIII with a relatively long, straight medial margin. Gnathosoma attached to a protrusible tube. Acetabula of separate genital plates.
Description. Male: Idiosoma dorsally 571 long and 389 wide, ventrally 591 long. Integument lineated, eyes and integument without pigment. Dorsal shield with six pairs of glandularia and the postocularia, dorsal furrow with two pairs of glandularia. Gnathosomal bay pointed posteriorly, CxI fused medially. Cxgl4 on CxIII, near suture line of CxIII/IV. No ridge present anterior to insertion of fourth legs. Genital field 118 wide, gonopore 34 long, with three pairs of glandularia, these lying on curved, indistinct genital plates. Gnathosoma elongated, attached to a protrusible tube. Length of P15: 20, 64, 60, 90, 40. Palp segments dorsal without stout setae, P2 ventrally with a short, relatively stout seta. Length of Ileg46: 76, 98, 131. Length of IVleg46: 84, 90, 92; IVleg6 with a terminal seta, 62 long. Excretory pore incorporated in ventral shield.
Etymology. Named for its superficial resemblance to L. zelandica Cook, 1983 .
Remarks. With the key of Cook (1983) the new species keys out as L. testacea Hopkins, 1969 . Differences with the latter species (in brackets) are the long medial margin of CxIII (short), no ridge anterior to insertion of fourth legs (with ridge) and the gonopore is shorter. A second species with the dorsal shield with six pairs of glandularia is L. zelandica Cook, 1983 . This species has the gnathosoma attached to a protrusible tube too. Differences with the new species (in brackets) are the presence of three pairs of glandularia in the dorsal furrow (two pairs), the presence of a ridge anterior to the insertions of the legs (no ridge), rounded medial margins of CxIII (straight), and the integument is pigmented (not pigmented).
