Description
. Male c.
18 mm
long,
H
= 1.7 mm. In alcohol, well-coloured specimens under low magnification with light brown body colour dorsally, a transverse band of darker brown near posterior metatergal margins and a small darker brown patch medially, paranota near-white. Antenna moderately long (
Fig. 69
adr).
Paranota
fairly wide,
R
= 1.5 (
Fig. 70
adr); posterior corners not turned up. Legs robust, tarsus slightly shorter than femur (
Fig. 71
adr). Epiproct with prominent paired, bluntly rounded projections (
Fig. 7B
).
Telopodite (
Figs 11
,
12
) sparsely setose almost to apex
, reaching almost to leg 5 when retracted. Solenomere arising at just under half the telopodite height, directed at c. 45° to telopodite axis basally but smoothly curving distally, terminating at one-third to half the prefemoral process length without subapical projection. Tibiotarsus arising slightly distal to solenomere origin, rod-like, bluntly tipped, one-third as long as solenomere and much narrower, directed at c. 45° to telopodite axis. Femoral process arising at level of solenomere origin, straight, blade-like, bluntly pointed, pressed close to prefemoral process, paralleling and reaching halfway to tip of latter, just past apex of solenomere, with a short, bluntly pointed posterior branch at one-third its length.
Prefemoral process about two-thirds the width of telopodite base at origin, straight, mesal edge with a short series of small teeth midway to apex, the latter finely-toothed, anteriorly concave.
No uncus.
Distribution and habitat.
In wet eucalypt forest, cool temperate rainforest, subalpine woodland and wetter microhabitats in dry eucalypt forest over c.
3500 km
2
in
north-east
Tasmania
(
Fig. 72
), from
60 m
to at least
1050 m
. The western and eastern range limits of
L. adrianae
correspond to the biogeographical divides known as the East Tamar Break and Goulds Country Break, respectively (
Mesibov, 1994
,
1997
). The most southerly known occurrence is near Castle Cary, north of Avoca.
L. adrianae
is abundant over most of its range and is by far the commonest dalodesmid in the wetter, forested parts of north-east
Tasmania
.
Remarks
.
L. adrianae
varies little in size, coloration and gonopod structure.
