less), white, eyeless, and lack tegmina and wings; 
in one specimen the posterior corners of the 
mesonotum are produced and appear to be 
nymphal tegminal pads which suggests that it is an 
immature male. Adult males of Nocticola may have 
fully developed tegmina and wings or their 
tegmina may be variably reduced and wings 
variably reduced or completely absent. Adult 
females are apterous. It is likely that the above 
specimens represent an undescribed species but 
adult males are needed to adequately describe a 
species in this genus.

Remarks 
There are 11 previously described species of 
Hensaussurea, all found in the southern half of 
Australia (Roth 1991b, fig. 45). Four species occur 
in Western Australia and of these at least three 
occur in the southwestern comer of the state. The 
new species, humphreysi described below also 
occurs in the southwestern part of Western 
Australia.

Paratypes 
Australia: Western Australia: 3 SS, same data 
as holotype, 3<? <J (1 with terminalia slide 351), 12, 
5 nymphs (1 6 each in WAM and MCZ, remainder 
in ANIC). 
All specimens were originally preserved in 
alcohol and then pinned; colour may have been 
altered by the fluid. 
Description 
Male 
Head hidden under pronotum (Figure 2B). 
Interocular space about the same as distance 
between antennal sockets (Figure 2A). Pronotum 
subparabolic (Figure 2B). Tegmina reduced to 
lateral pads, completely separated from the 
mesonotum, and reaching to or slightly beyond 
hind margin of the mesonotum. Hind wings absent 
(Figure 2B). Front femur Type B2, with four large 
proximal spines; pulvilli present on four proximal 
tarsomeres, tarsal claws symmetrical, simple, arolia 
present. Abdominal terga unspecialized. Supraanal 
plate trigonal, apex with a shallow U-shaped 
excavation forming two small lobes, and a few 
short setae on either side of the excavation; 
paraprocts dissimilar, both with spinelike 
processes (Figures 2B, C). Subgenital plate with 
strongly dissimilar styli, the right one elongated 
with a few large spines along the margins, the 
spinelike apex directed towards the left and 
reaching the much smaller, cylindrical left style 
(Figure 2D). Genitalia as in Figure 2D: hook on the 
left side, with a preapical incision; median 
phallomere distally enlarged, tapering to an acute 
apex; right phallomere with two principal sclerites 
one of them a large cleft structure; overlying the 
right phallomere is a membrane bearing four 
spines. Colour pale with dark markings: Head with 
pale occiput, a dark brown longitudinal band 
extending from the vertex to the lighter clypeus, 
labrum lighter brown, cheeks white (Figure 2A). 
Pronotal disk with a light brown macula on distal 
half, surrounded by a dark brown band, lateral and 
anterior borders white; the lateral pale borders of 
the pronotum continue on the tegmina and 
metanotum, and more narrowly on the abdominal 
terga; the mesonotum has two and metanotum 
four brown dots. The lateral pale margins of the 
abdominal terga are succeeded mesad by a dark 
brown longitudinal band, then by a large light 
brown middle zone (Figure 2B). Abdominal sterna 
brown, lateral margins pale. Cerci dorsally with 
two black basal segments, the remainder white, 
ventrally the cercomeres are dark brown on basal 
halves, and pale distally. Legs pale, without 
markings. 
Female 
Supraanal plate with apex shallowly excavated. 
Abdominal terga dark brown except for pale lateral 
borders, and a pale macula on either side of the 
midline on segments 1 and 2; supraanal plate with 
a white macula on distomedial region. 
Nymph 
The nymph resembles the adult (the colour 
pattern may differ only slightly) except for the 
complete absence of tegmina.
