Discussion and differential diagnosis
.
Pollanisus angustifrons
has the patagia and abdomen yellowish green dorsally (
Tarmann 2004
). Several specimens were excluded from the
paratype
series due to having white instead of black ocelli (
Tarmann 2004
). However, this character turned out to be very variable and has no diagnostic value (
Mollet & Tarmann 2010
). Therefore, these additional specimens widen the known distribution area to the north and far to the south, with a population cluster in the Borumba Dam area, Southern
Queensland
.

The habitus and the head ratios in
Pollanisus
species 4
and
P.
species 5 (the only
two specimens
with a green abdomen from Mt Bellenden-Ker) give arguments to conclude that these two ‘species’ are conspecific and close enough in their head ratios to accept that they belong to
P. angustifrons
.
The other
three specimens
in
Pollanisus
species 5
(from Kennedy River and Kuranda) with coppery abdomen and similar head ratios with
P. incertus
(Group 2) must be excluded from
P. angustifrons
.
One of the
two specimens
from Mt Belleden-Ker (figured by
Tarmann 2004
, pl. 27, fig. 2) was later photographed (visit in ANIC, on
4.IV.2013
). The green colour of the abdomen has become coppery in the meantime. The second specimen was described with a slightly shiny coppery abdomen upperside (
Tarmann 2004
) but it is supposed that the colour changed and was previously green (collected in the same area and nearly at the same time). One specimen from Moreton Island,
Queensland
, shares the similar head feature and ratios, therefore it is included into the
P. angustifrons
series.
P. angustifrons
is similar in habitus as
P. acharon
and
P. jumbun
but differs in the head features and ratios. Another species,
P. marriotti
, has very close head ratios but differs in a bigger size and it only occurs in South
Victoria
near Melbourne.
Phenology and bionomics.
At Murray Upper Falls
one specimen
was obtained from a larva collected on
H. scandens
(Dilleniaceae)
and another was collected at night. This, as well as several published observations (
Tarmann 2004
), suggest that this species has a nocturnal activity.
