Diagnosis.
Brueelia coryliventer
is most similar to
B. tkachi
, with which it shares the following characters: both sexes with moderate pigmentation on sternal and subgenital plates; lateral margins of preantennal head clearly convex; 1
ps
present on male abdominal segment III on each side; 2
ps
present on male abdominal segment IV on each side; 2
ps
on female abdominal segment IV on each side; female subgenital plate slenderly pentagonal. These two species differ in the following characters: frons flat and angular in
B. coryliventer
(
Fig. 20
) but gently rounded in
B. tkachi
(
Fig. 19
);
psps
present in
B. coryliventer
(
Fig. 7
) but absent on male tergite V in
B. tkachi
(
Fig. 5
);
ps
present on female abdominal segment III in
B. coryliventer
(
Fig. 8
) but absent in
B. tkachi
(
Fig. 6
); basal plate with narrow, rounded anterior end in
B. coryliventer
(
Fig. 12
) but with broad, flattened anterior end in
B. tkachi
(
Fig. 11
); male mesosome with
mf
extending farther posterior and being broadly triangular in
B. tkachi
, but shorter and with small, rounded
mf
in
B. coryliventer
; male parameres constricted in
B. coryliventer
but not constricted in
B. tkachi
.
Description.
Head cone-shaped (
Fig. 20
). Frons flat. Lateral margins of preantennal head converging anteriorly, slightly convex, abruptly rounded anteriorly. Marginal carina broad. Head chaetotaxy as in
Fig. 20
. Gular plate long, broad, triangular. Overall body pigmentation light, with moderately pigmentation on head carinae and nodi, mandibles, anterior margin of scape, pedicel, flagellomeres I–III, proepimera, metepisterna, and subgenital plates and sternal plates IV–VI of both sexes. Pigmentation of sternal plates lighter in female. Measurements as in Table 1.

Male.
Thorax and abdomen as in
Fig. 7
; segment III with 1
ps
; segment IV with 2
ps; psps
present on tergite V; segment XI with 4 setae. Male genitalia as in
Fig. 12
. Basal plate roughly rectangular, anterior margin rounded. Mesosome with strongly sinuous distal thickening; both
lf
and
mf
smaller in relation to parameres, and
mf
reaching slightly more distally than
lf
. Parameres constricted midway along lateral margin.
Female.
Thorax and abdomen as in
Fig. 8
.
ps
present on segment III. Segments IV–VII each with 2
ps
. Crosspiece of subgenital plate with narrow connection to main plate as in
Fig. 16
. Vulval margin gently rounded (
Fig. 16
), with 4–5 slender
vms
on each side, and 4 thorn-like
vss
on each side; 4 slender
vos
on each side; 1 distal
vos
median to
vss
on each side.
Comments.
Creatophora
Lesson, 1847
, is a monotypic genus. Unlike
Lamprotornis
Temminck, 1820
and
Spreo
,
Creatophora
is not part of the “African” starling radiation, but belongs to the “Eurasian” radiation (
Lovette & Rubenstein 2007
). We examined louse material from the following starlings and mynahs belonging to the Eurasian radiation:
Acridotheres fuscus fuscus
(Wagler, 1827)
,
A. fuscus torquatus
Davison, 1892
,
A. ginginianus
(Latham, 1790)
,
A. grandis
Moore, 1858
,
A. tristis tristis
(Linnaeus, 1766)
,
Gracupica contra
contra
(Paykull, 1807)
,
G. nigricollis
(Linnaeus, 1758)
,
Pastor roseus
(Linnaeus, 1758)
,
Sturnia malabarica nemoricola
Jerdon 1862
,
S. sinensis
(Gmelin, 1788)
,
Sturnus vulgaris
Linnaeus, 1758
, and
Temenuchus pagodarum
(Gmelin, 1789)
. None of these samples belong to the
clara
species group of the genus
Brueelia
.

Etymology.
The species epithet derives from Latin “
corylus
” = “hazel”, and “
ventrum
” = “ventral”, referring to the hazel-brown sternites of the
holotype
male.
