Limbodessus palmulaoides
Watts & Humphreys, 2006
(
Figs 180–193
)
Source of material.
One
specimen of instar I was used for the description (
Table 1
).
The
larva was collected in association with adults at the following locality:
Australia

Carey
palaeovalley
,
Mounth Windarra
calcrete, MEB site 73, BES 10292,

Diagnosis.
No diagnosis is provided owing to a lack of specimens of instars II and III.
Instar I
(
Figs 180–193
). Head (
Figs 180–188
). Cephalic capsule not strongly elongate (HL/HW less than 1.55); seta PA3 inserted far from setae PA1 and PA2; A3 less than 2.15 times longer than A1; A3 (instar I): (0) less than 2.05 times longer than A2; MP2 less than 1.45 times longer than MP1; MP2 1.95–2.65 times longer than MP3; LP2 less than 1.30 times longer than LP1. Legs (
Figs 189–190
). L3 less than 2.85 times longer than HW. Abdomen (
Figs 191–193
). U more than 3.75 times longer than LAS; U less than 2.35 times longer than HW; U1 more than 1.45 times longer than U2. Chaetotaxy. Frontoclypeus with 12 lamellae clypeales; additional setae on U present. Measurements and ratios that characterize the body shape are shown in
Table 3
.
Instar II.
Not available.

FIGURES 189–193.
Limbodessus palmulaoides
, first-instar larva. 189, left metathoracic leg, anterior aspect; 190, right metathoracic leg, posterior aspect; 191, abdominal segment VIII, dorsal aspect; 192, abdominal segment VIII, ventral aspect; 193, right urogomphus, dorsal aspect. Scale bars = 0.10 mm.
Remarks.
The species is not diagnosed above because of lack of instars II and III. However, it can be separated from all the other species described as instar I by the presence of additional setae on the urogomphus (
Fig. 193
), a unique feature within the taxa examined, and by the combination of characters given under the description.
