Ancylopus melanocephalus
(Olivier, 1808)
Diagnosis.
Body elongate-oval and of moderate size, length 4.0–6.0 mm; the elytra almost always with black maculae laterally and longitudinal band along the sutural line; elytral basal edge thickened and raised; labrum with sides subparallel; mandible with acute apex. Female pronotum with lateral sulci connected medially by an arcuate ridge. Male mesofemur with a fringe of long hairs along inner edge.
Ancylopus melanocephalus
can be distinguished from its congeners by a body length of 4.0–6.0 mm, mesotibia of male with inner margin slightly undulate and without a tooth, and the inner edge of the metatibia with minute serrations (
Figs. 1–6
).
The species most similar to
A
.
melanocephalus
is
Ancylopus ceylonicus
Strohecker, 1971
known from
Ceylon
. Both species can be distinguished by the following key. Additionally,
A
.
ceylonicus
can be distinguished by the ferruginous color of the head, antennae, and legs and the black scutellum. The elytral suture, elytral apex, and elytral lateral margin are black, as well as a large, mediolateral elytral spot (
Figs. 7
). The male genitalia are also different (compare
Fig. 3
and
Fig. 8
).

Habitat.
The
two specimens
were collected by blacklight traps deployed for a study to document the insect biodiversity of
Gabal Shada Alalaa Nature Reserve
in southwestern
KSA
(
Figs. 10
).
This area
is dominated by
