Type
material examined.
Xantholinus interocularis
Eppelsheim, 1895
. It was not possible to find the
type
/s of
Xantholinus interocularis
, described from
Togo
. All reasonable steps were exhausted to trace the original
type
material of this taxon. Eppelsheim
type
specimens are housed in the
NHMW
. The curator of
NHMW
searched for
type
material, but without success. We can only conclude that the
type
material has been lost. To stabilise the systematic position of this species in this complex species group, we decided to designate a
neotype
. The specimen selected as the
neotype
matches the original description of
Eppelsheim (1895)
and falls within the area of original
type
locality (
Togo
).
Neotype
(by present designation) ♂:
TOGO
: “
Togo
” (
DEI
). The specimen is chosen as
neotype
. The labels “
Neotypus
Xantholinus interocularis
Epp., Bordoni
des. 2014” and “
Thyreocephalus interocularis
(Epp.)
, Bordoni det. 2014” were attached to this specimen.

lectotype
of the species. It is identical to
T. interocularis
. The labels “

Redescription.
Body length
15–19 mm
; length from anterior margin of head to posterior margin of elytra:
9– 11 mm
. Black with bluish elytra and abdomen slightly reddish. Shiny. Head and pronotum with micro-punctation. Head and pronotum and related punctation as in
Fig. 158
; labrum as in
Fig. 159
. Elytra longer and wider than pronotum, squared, slightly dilated posteriad, with rounded humeral angles. Surface with wide and superficial punctation, arranged in three series, one near suture, one median and one lateral. Abdomen with feeble or evident traces of transverse micro-striation, with fine and very spaced punctation, arranged in a few series.
Male
. Tergite 10 and sternite 9 of male genital segment as in
Figs. 160, 161
. Aedeagus relatively small,
1.9–2.6 mm
long, median lobe generally wide, sub-triangular (
Fig. 162
), rarely markedly narrower and variably shaped, but always apically pointed (
Figs. 163, 164
); parameres symmetrical (
Figs. 162, 165
); inner sac ribbon-like, wide and long, folded on itself, covered with little scales.
Differential diagnosis.
Thyreocephalus interocularis
differs from the similar
T. basilewskyi
in disc of head generally sparsely and finely punctured and in paramere of aedeagus relatively long. The punctation of the head in extreme specimens of both species is very similar.
Distribution.
Distributed in West, Central and East Africa (
Fig. 147
).
Remarks.
This species is variable in dimensions of the body and aedeagus, and in punctation as well. For example the specimens from Kivu have a larger aedeagus (about
2.6 mm
long). The most constant character is the length of paramere in relation to the length of aedeagus.
