Description.
Both sexes.
Head broadly acorn-shaped (
Fig. 87
). Frons flat to slightly concave. Lateral margins of preantennal head convex. Head chaetotaxy as in
Fig. 87
;
ads
mesosetae. Coni and antennae sexually dimorphic. Base pigmentation pale brown; marginal and marginal temporal carinae, head nodi, margins of antennal socket, proepimera, metepisterna and pleural incrassations dark brown with slight red tint; gular plate, sternal plates IV–VI and subgenital plate medium brown; meso- and metasternal plates and sternal plates II–III pale brown.
Male.
Coni short, blunt, about half as long as scape (
Fig. 87
). Pteronotum with 5–6
mms
on each side (
Fig. 85
). Abdominal plates and chaetotaxy as in
Fig 85
. Male genitalia as in
Figs 88–90
. Basal apodeme constricted at midlength, distal end wider than proximal end (
Fig. 88
). Proximal mesosome rectangular, with flat proximal margin (
Fig. 89
). Mesosomal lobes rectangular, distal margin almost flat dorsally. Large submedial ventral nodi project distal to dorsal margin of mesosome. Marginal thickening of mesosomal lobes not displaced medially. Gonopore with lateral extensions in anterior end; 2
ames
sensilla on each side near antero-lateral corners of mesosomal lobes; 2
pmes
sensilla on each side lateral to gonopore; 2
pmes
sensilla submedially near posterio-lateral corners of mesosomal lobes. Parameral heads roughly rounded rectangular, with sinuous posterior margin (
Fig. 90
). Parameral blades elongated, tapered, widely divergent distally;
pst1–2
widely separated. Measurements ex
Ianthocincla mitrata major
(n = 1): TL = 1.32; HL = 0.34; HW = 0.34; PRW = 0.22; PTW = 0.34; AW = 0.50.
Female.
Coni long, pointed, reaching beyond distal margin of scape (
Fig. 86
). Pteronotum with 5
mms
on each side (
Fig. 86
). Abdominal plates and chaetotaxy as in
Fig. 86
. Vulval margin gently rounded (
Fig. 91
), in 2 of
3 females
slightly flattened medially, with 4 slender
vms
and 5–7 thorn-like
vss
on each side. Medial-most
vms
much shorter than other
vms
; 3–5 slender
vos
; distal
vos
just anterior to
vss
. Measurements ex

Remarks.
We have examined the
holotype
and the only other previously known specimen of
Brueelia rhinocichlae
Eichler, 1957
, to confirm that this species is a member of
Priceiella
(
Camurnirmus
)
. However, the
holotype
is poorly preserved. Few characters of the head or female genitalia can be clearly seen, and the abdominal chaetotaxy is partially obscured. What can be seen of the overall morphology is indistinguishable from that of a female from
Ianthocincla mitrata major
(Robinson and Kloss, 1919)
. Therefore, we redescribe and reillustrate
P.
(
C
.)
rhinocichlae
based on material from this host subspecies. Future collections from both host subspecies will be necessary to establish with more certainty whether the
Camurnirmus
on both hosts represent the same species.
