Comparative remarks
. This species resembles
L. candezei
,
L. ganglbaueri
, and
L. solai
based on the body size, habitus, reddish brown to brown coloration, and elongate pronotum in males. It differs in having a usually slightly lighter body and pubescence, male antennae shorter, not reaching posterior angles of pronotum, aedeagus with longer median lobe and differently shaped parameres, ovipositor in females only about 2.0–2.5 times as long as the width of a large sclerite of bursa copulatrix (about 3–4 times in the above mentioned species), and a large sclerite of bursa copulatrix relatively larger, more transverse, and with denser spines and spinules (
Figs 36–38, 44–46, 49–51
,
52–54, 59, 62–64
,
70, 71, 77–79
,
80–87
,
95–99
).
Diagnostic characters
. Male (
Figs 80–85
,
88–90, 92–96
). Body
7.5–13.4 mm
long and
2.4–3.8 mm
wide (
syntype
of
A. lithophila
:
7.2 mm
long,
2.2 mm
wide;
holotype
of
L. freidbergi
:
10.8 mm
long,
2.9 mm
wide). Body moderately shiny to shiny, reddish brown to brown (in some cases dark brown), with antennae, pronotal posterior angles and legs slightly lighter; covered with combination of white and greyish to pale brown setae (in some cases pronotum covered only with white setae), all moderately long and thick. Antenna moderately long, surpassing 3/4 of pronotal length or almost reaching pronotal posterior angles. Antennomere III about 1.3 times as long as antennomere IV, median antennomeres serrate, about 1.00–1.15 times as wide as long. Pronotum 1.2–1.3 times as long as wide, sides almost subparallel, with posterior angles subparallel to slightly divergent, disk moderately densely to densely covered with large, moderately deep punctures, intervals between punctures usually 0.5–1.0 times as a diameter of puncture. Scutellar shield about 1.35–1.50 times as long as wide, with anterior margin slightly concave. Elytra 2.2–2.4 as long as wide, and 2.15–2.40 times as long as pronotum, with punctures of two sizes; smaller punctures of about 2/3 of size of larger punctures. Aedeagus with median lobe almost reaching apices of parameres, gradually narrowing toward apex; paramere subparallel-sided in more than basal half, then sinuate, apically with inner sides slightly diverging; apical parameral lobe robust, rounded; subapical hook short and sharp.

L. freidbergi
. Scale bars = 1.0 mm (Figs 88–91), 0.5 mm (Figs 94–99); Figs 92 and 93 not to scale.
Female (
Figs 86, 87
,
91, 97–99
). Body 10.0–13.0 mm long and
2.7–3.8 mm
wide. Body more robust than in male. Antenna shorter, not reaching 2/3 of pronotal length. Antennomere III 1.15–1.20 times as long as antennomere IV, median antennomeres serrate, about as long as wide. Pronotum relatively shorter and wider, 1.10–1.15 times as long as wide, sides widely to equally rounded, posterior angles subparallel to slightly convergent. Elytra combined 2.10–2.25 times as long as wide, about 2.1 times as long as pronotum. Ovipositor and sclerites of bursa copulatrix as in
Figs 97–99
, respectively.
Immature stages unknown.
Intraspecific variability
. This species is slightly variable in the body size, the shape of pronotum and the density of spines in the large sclerite of bursa copulatrix (
Figs 80–90, 98, 99
). Most males are only up to about
11 mm
long, including both available specimens from
Egypt
(
Figs 80–83
). One male specimen from
Israel
: Ezuz resembles a female with his large size (
13.4 mm
long,
3.8 mm
wide), habitus and a relatively shorter and more robust pronotum.

Remarks
. We found no morphological differences between
Lacon lithophilus
(
Candèze, 1857
)
and
L. freid- bergi
Platia, 2010
, and therefore we synonymize here the latter with
L. lithophilus
.
The data in the locality label „As. m. Leder“ (i.e.,
Asia Minor
, leg. Leder) under one of the examined specimens is dubious taking into consideration the currently known distribution of
L. lithophilu
s (i.e., the southern Levant and
Egypt
;
Fig. 194
). Additionally, there is a female specimen from „
Syria
“ (collection of O. Schwarz, SDEI) which is not possible to assign to the country where it was collected since historical
Syria
included also other present-day countries.
