Draculoides belalugosii
sp. nov.
, holotype male (WAM T135952): A. Body, dorsal; B. Body, ventral; C. Body, lateral; D. Flagellum, dorsal; E. Flagellum, ventral; F. Flagellum, lateral. The scale bar shown in image A is 1 mm and also applies to B and C and the scale bar shown in image D is 200 µm and also applies to E and F.
Diagnosis.
The shape of the male flagellum is distinctive as it is short, broad, and rounded. It most closely resembles
Draculoides confusus
in lateral profile but differs in the distal position of dm
4 in
D. belalugosii
(sub-distal in
D. confusus
) and the close proximity of dl
3 in
relation to vl1 (dl3 is distally placed and widely separated from vl
1 in
D. confusus
). Females differ from all other species of
Draculoides
by the comparatively short, rounded, unconnected spermathecae of the female genitalia.
Draculoides belalugosii
can be diagnosed from all other
Draculoides
species that were sequenced at COI and 12S by the 50bp mini-barcodes shown in
Figures 3
and
5
.

Remarks.
Draculoides belalugosii
is known from several locations within an area known as Buckland Hills, situated in the eastern part of the Hamersley Range,
Western Australia
(
Fig. 1E
).
Draculoides christopherleei
also inhabits this area as well as two distinctive lineages (SCH100 and SCH101) which may represent new species but for which we do not have sufficient data to describe at this time.

Etymology.
This species is named for actor Bela Lugosi (1882–1956) who played the role of Dracula in the 1931 movie of the same name.
