Diagnosis.
The male genitalia of
Priceiella
(
Camurnirmus
)
paulbrowni
n. sp.
(
Figs 296–298
) are intermediate between
Pr
. (
Cm.
)
hwameicola
n. sp.
(
Figs 288–290
) and
Pr
. (
Cm.
)
nipalensis
, and
Pr
. (
Cm.
)
rhinocichlae
(
Eichler, 1957
)
. As in
Pr
. (
Cm.
)
hwameicola
(
Fig. 289
) and
Pr
. (
Cm.
)
nipalensis
, the distal mesosome is rounded triangular in
Pr
. (
Cm.
)
paulbrowni
(
Fig. 297
), but as
in
Pr
. (
Cm.
)
rhinocichlae
the distal mesosome of
Pr
. (
Cm.
)
paulbrowni
(
Fig. 297
) is also dominated by a broad transversal thickening, and the parameres are almost as long as those of
Pr
. (
Cm.
)
rhinocichlae
. In
Pr
. (
Cm.
)
hwameicola
(
Fig. 289
) and
Pr
. (
Cm.
)
nipalensis
the distal thickening of the mesosomal lobes are more slender and not medianly continuous, and the parameres are much shorter. In both
Pr
. (
Cm.
)
rhinocichlae
and
Pr
. (
Cm.
)
paulbrowni
(
Fig. 296
) the distal half of the basal apodeme is much wider than the proximal half, whereas
in
Pr
. (
Cm.
)
nipalensis
and
Pr
. (
Cm.
)
hwameicola
(
Fig. 288
) the basal apodeme is about equally wide in distal and proximal halves. In both
Pr
. (
Cm.
)
rhinocichlae
and
Pr
. (
Cm.
)
paulbrowni
(
Fig. 297
), the horn-shaped lateral extensions of the gonopore originate from the proximal margin of the gonopore, whereas in
Pr
. (
Cm.
)
hwameicola
(
Fig. 289
) these extensions originate from the lateral margins of the gonopore.
Priceiella
(
Camurnirmus
)
paulbrowni
can be separated from
Pr
. (
Cm.
)
rhinocichlae
by the following characters: distal mesosome quadratic
in
Pr
. (
Cm.
)
rhinocichlae
but rounded triangular in
Pr
. (
Cm.
)
paulbrowni
(
Fig. 297
); parameres with characteristic notch on lateral margin about 1/3 from distal tip associated with
pst
2
in
Pr
. (
Cm.
)
rhinocichlae
, but parameres without such notch in
Pr
. (
Cm.
)
paulbrowni
(
Fig. 298
); gonopore longer than wide
in
Pr
. (
Cm.
)
rhinocichlae
, but wider than long in
Pr
. (
Cm.
)
paulbrowni
(
Fig. 297
). Vulval chaetotaxy partially overlapping between
Pr
. (
Cm.
)
rhinocichlae
an
Pr
. (
Cm.
)
hwameicola
(

Pr
. (

has 5– 7
vss
[

Pr
. (
Cm.
)
rhinocichlae
lack the
psps
of tergopleurite VIII present in
Pr
. (
Cm.
)
paulbrowni
(
Fig. 293
) and
Pr
. (

(

Description.
Both sexes
. Head shape, structure, and chaetotaxy as in genus description and
Fig. 294
. Dorsal preantennal suture absent. Only marginal carina, mandibles, head nodi, and gular plate with dark pigmentation. Thoracic and abdominal segments as in genus and subgenus descriptions and
Figs 292–293
. Lateral tergopleurites and pleural incrassations as in
Fig. 316
.

Etymology.
The species epithet is in honour of Paul Brown, Senior Curator of Sternorrhyncha, lice, and thrips at the NHML. His monumental efforts in loaning large numbers of specimens made this revision possible.
