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 omega after Greek “ὦμέγα”.
DIAGNOSIS. Alpiscorpius omega sp. n. is a cryptic species of the “ gamma group” of the “ mingrelicus compleX”, defined by ŠtundlovÁ et al. (2019) as “Karyotypic race IV (Ega 88)”, which has 2n = 88 chromosomes. The karyotype is composed of 20 metacentric, 2 submetacentric, 6 subtelocentric, and 60 telocentric chromosomes (fig. S2E in ŠtundlovÁ et al., 2019). Polymorphism for chromosomal fusion/fission is present in three specimens from different localities. Their karyotypes are: 2n = 87 (heterozygous for fusion, 42 bivalents and one trivalent, fig. S3G in ŠtundlovÁ et al., 2019) and 2n = 89 (heterozygous for fission, 43 bivalents and one trivalent, fig. S3D in ŠtundlovÁ et al., 2019). The rDNA clusters are located in the subterminal region of the long arms of the telocentric chromosome pair 27 (fig. 2I and fig. S2E in ŠtundlovÁ et al., 2019). Number of pectinal teeth (Dp) in male usually 8 (>75% of eXamined specimens). Number of patellar ventral trichobothria (Pv) 5 (ca. 90%). Reduction of patellar eXternal trichobothria from 4 to 3 common in group et (25%) (see Figs. 59–64). There is no eb
a
=4 reduction.
DESCRIPTION OF THE MALE HOLOTYPE. The following description is based primarily on the holotype male. Measurements of the holotype are presented in Table 2. 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 very finely granulated and without lateral carinae. Vesicle of telson swollen and elongated, with short highly curved aculeus. Vesicle essentially void of granules. Pectinal teeth number 8/8. Pedipalps carinae well-developed ( Figs. 33–35). Movable fingers bear 7 rows of denticles with eXternal and internal denticles. Trichobothrial pattern type C, neobothriotaXic: chela ventral = 4/4; patellar eb = 4/4, eb a =4/4, esb = 2/2, em = 3/3, est = 3/3, et = 5/5; patellar ventral = 5/5. Both pedal spurs present on all legs; tibial spurs absent. Tarsus of legs with single row of spinules on ventral surface.
VARIABILITY. We scored standard phenotypic markers for 22 type specimens (21♂ 1♀), with the following variation observed:
Dp in males (n=21): 7/7 (2), 7/8 (3), 8/8 (13), 8/9 (3); in total, 7 in 16.67% (7); 8 in 76.19% (32), and 9 in 7.14% (3); mean = 7.90, SD = 0.48.
Dp in females (n=1): 6/6.
Pv (n=22): 4/5 (1), 5/4 (4), 5/5 (17); in total, 4 in 11.36% (5), and 5 in 88.63% (39); mean = 4.89, SD = 0.32.
et (n=22): 0/3 (1), 3/3 (1), 3/4 (2), 4/3 (6), 4/4 (12); in total (n=43, not counting one aberrant pectine), 3 in 25.58% (11) and 4 in 76.74% (32); mean = 3.74, SD = 0.44.
