ETYMOLOGY.
Di Caporiacco (1950)
named three subspecies of
Euscorpius germanus
after the letters of the Greek alphabet
alpha
,
beta
, and
gamma
. We continue in this style for another cryptic species and name it
kappa
after Greek “κάππα”.
DIAGNOSIS.
Alpiscorpius kappa
sp
.
n
.
is a cryptic species of the “
germanus
group” of the “
germanus
compleX”, defined by
ŠtundlovÁ et al. (2019)
as “Karyotypic race III (Ege 46c)” which has 2n = 46 chromosomes. The karyotype is composed of 42 metacentric and 4 submetacentric chromosomes (fig. S1F in
ŠtundlovÁ et al., 2019
). The rDNA clusters are located in the terminal region of the long arms of the metacentric chromosome pair 14 (fig. 2E and fig. S1F in
ŠtundlovÁ et al., 2019
). Number of pectinal teeth (Dp) in male usually 7 (70% of eXamined specimens). Number of patellar ventral trichobothria (
Pv
) usually 5. Reduction of patellar eXternal trichobothria from 4 to 3 present common in group
eb
a
(20%); no reduction in group
et.

DESCRIPTION OF THE MALE
HOLOTYPE
.The following description is based primarily on the
holotype
male. Measurements of the
holotype
are presented in
Table 1
. Carapace, tergites, and pedipalps reddish-brown; carapace with some darker mottling; metasoma dark reddish-brown with dark mottling; telson, legs, and sternites dark yellow to reddish-brown; chelicerae light, slightly reticulated. Anterior edge of carapace essentially straight; smooth and lustrous, lacking any indication of carinae. There are two lateral eyes. Median eyes and tubercle are small in size. Tergites I–VII essentially smooth; tergite VII lacking lateral and median carinal pairs. Sternites III–VII smooth and lustrous; VII lacking lateral and median carinae. Stigmata are small, narrow elliptical. Metasomal segment V smooth without granulation and carinae. Vesicle of telson swollen and elongated, with short highly curved aculeus. Vesicle essentially void of granules, lustrous. Pectinal teeth number 8/7. Pedipalp carinae well-developed (
Figs. 33–35
). Movable fingers bear 7 rows of denticles with eXternal and internal denticles. Trichobothrial patterns type C, neobothriotaXic: chela ventral = 4/4; patellar

VARIABILITY. We scored standard phenotypic markers for
5 type
specimens (all
♂
), with the following variation observed:
Dp in males
(n=5): 7/7 (2), 7/8 (2), 8/7 (1); in total (n=20),
7 in
70% (7), and
8 in
30% (3); mean = 7.30,
SD
= 0.48.
Pv
(n=5): 5/6 (1), 5/5 (9); in total,
5 in
90% (9) and
6 in
10% (1); mean = 5.10,
SD
= 0.32.
et
(n=5): 4/4 (10); in total,
4 in
100% (10).
eb a
(n=5): 4/3 (2), 4/4 (3); in total,
3 in
20% (2) and
4 in
80% (8); mean = 3.80,
SD
= 0.42.
DISTRIBUTION.
Slovenia
(Gorenjska, Goriška) (

).
NOTES. Slovenian populations of “
Euscorpius germanus
” (found only in the western part of
Slovenia
) listed by
Fet et al. (2001)
could refer to both
A. kappa
sp
.
n
.
and
A. lambda
sp
.
n
.
The former, however, appears to have a more restricted range in western
Slovenia
and is currently known only from two localities. In Gorenjska region,
A. kappa
sp
.
n
.
is sympatric with
A. omikron
sp
.
n
.
(“
gamma
group”, see below).
