Material examined.
Four
paratypes
(
3 females
and
1 male
) preserved in 70% ethanol and mounted on slides by the authors, Fertőújlak (Hungary), position
N 47°40'58"
E 16°50'37"
, deposited at the US,
9.iv.1999
,
G. Traser
leg.
Seven
topotypic specimens (
4 males
and
3 females
) on slides deposited at the
US
,
14.vii.2017
,
D. Winkler
leg.
Remarks.
Specimens from the
type
series preserved in alcohol were in excellent conditions, with clearly visible chaetotacic characters. All specimens studied have the same morphology and chaetotaxy and match the description of
Traser (2000)
, but with the following differences: Dorsal head macrochaetae formula
A
0
A
2a

; interocular chaetotaxy with chaetae
s
,
t
,
p
,
q
and 2‒3 intraocular scales (
Fig. 1
). Also all characters, except the absence of dorsal cephalic macrochaeta S3, match the description done for
L. florae
sp. nov.
(see
Figures 12
–
33
).

Discussion.
Dorsal cephalic macrochaetae formula of
L. arrabonicus
was described following RST system as
R
0
R
1
R
2
R
3
P
o
(
Traser 2000
). In the original description (
Traser 2000:
Figure 2
) the illustration of dorsal head chaetotaxy clearly shows that
R
1
is actually
R
1s
, and
R
3
is actually
R
2
so the macrochaetae formula actually corresponds to the AMS scheme
A
0
A
2a
A
2
A
3
Pa
5
. In all specimens we have studied this formula is also
A
0
A
2a
A
2
A
3
Pa
5
. The original description erroneously missed interocular chaeta
q
(
Traser 2000:
Figure 3
), which is in fact present both in specimens of the
type
series, as well as in all other studied specimens from various locations.
