Alpiscorpius beta is a cryptic species of the “ alpha group” of the “ germanus compleX” defined by ŠtundlovÁ et al. (2019) as “Karyotypic race I (Eal 60)”, which has 2n = 60 chromosomes. The karyotype is composed of 34 metacentric, 14 submetacentric, 2 subtelocentric, and 10 telocentric chromosomes (fig. S1A in ŠtundlovÁ et al., 2019 ). The rDNA clusters are localized in the subterminal region of the long arms of the metacentric chromosome pair 4 (fig. 2A and fig. S1A in ŠtundlovÁ et al., 2019 ). Number of pectinal teeth (Dp) in male usually 8. Number of patellar ventral trichobothria ( Pv ) varies from 5 to 6. Reduction of patellar eXternal trichobothria from 4 to 3 rare in series et (<10%) and more common in series eb a (>10%); see also Notes.

Measurements of this specimen 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. 13–15 ). Trichobothrial pattern type C, neobothriotaXic: chela ventral = 4/4; patellar eb = 4/5, eb a =4/4, esb = 2/2, em = 3/3, est = 3/3, et = 4/5; patellar ventral = 5/5. Tarsus of legs with single row of spinules on ventral surface. VARIABILITY. We scored standard phenotypic markers for 7 eXamined specimens ( 5♂ , 2♀ ), with the following variation observed: Dp in males (n=5): 7/7 (1), 8/8 (3), 8/9 (1); in total, 7 in 20% (2), 8 in 70% (7) and 9 in 10% (1); mean = 7.90, SD = 0.57. Dp in females (n=2): 6/4 (1), 6/6 (1). Pv (n=7): 5/5 (3), 5/6 (1), 6/5 (1), 6/6 (2); in total, 5 in 57.14% (8), and 6 in 42.86% (6); mean = 5.43, SD = 0.51. et (n=7): 4/3 (1), 4/4 (13); in total, 3 in 7.14% (1), and 4 in 92.86% (13); mean = 3.93, SD = 0.27. eb a (n=7): 4/3 (2), 4/4 (12); in total, 3 in 14.29% (2) and 4 in 85.71% (12); mean = 3.86, SD = 0.36. DISTRIBUTION. Italy (Piedmont, Val d’Aosta), Switzerland ( Valais : Zwischbergental) ( Fig. 71 ). NOTES. This taXon was first informally delineated by Capra (1939) as “Form B” from Val d’ Aosta, including the marginal, westernmost populations of “ Euscorpius germanus ” (sensu lato). It was formally described as a subspecies by Di Caporiacco (1950) . Bonacina (1980) synonymized E. g. beta with E. g. germanus and noted that both taXa had five trichobothria on ventral aspect of patella ( Pv =5). This synonymy, however, created a disjunct distribution for E. g. germanus sensu Bonacina (1980) . Italian populations studied by Bonacina (1980) should be reassessed, and their phenotypic markers scored from the material deposited in MCSNB. Populations from Fontainemore ( Val d’Aosta , Italy ) and Gondo, on the Simplon Pass road ( Switzerland , Valais ) were studied by Gantenbein et al. (2000) who synonymized E. germanus beta with E. alpha . The Gondo (or Simplon) population was studied in more detail by Braunwalder (2001) and Fet & Braunwalder (2005). Gantenbein et al. (2000) published a 16S mtDNA sequence ( AJ389379 ), identical for Gondo and Fontainemore populations, which closely matches those of Eal 60 (= A. beta ) obtained independently by ŠtundlovÁ et al. (2019) . Following Gantenbein et al. (2000) , both Braunwalder (2001) and Fet & Braunwalder (2005) addressed the Swiss population from Simplon as E. alpha . However, both Gantenbein et al. (2000) and Fet & Braunwalder (2005) noted morphological features (Pv=5 to 6, mean 5.40) distinguishing it from the more eastern Swiss populations of E. alpha ( Ticino , Grisons ), which usually had Pv=6. Fet & Braunwalder (2005) scored the standard phenotypic markers for 25 specimens of this species from Switzerland (Simplon), with the following results : Dp in males (n=6): mean= 8.17, SD = 0.58. Dp in females (n=17): mean = 6.71, SD = 0.52, Pv (n=25): mean = 5.40, SD = 0.50, et (n=23): 3 in 2.17% (1), and 4 in 97.83% (45); mean = 3.98, SD = 0.15. These data are consistent with the 7 eXamined specimens used for karyotype and DNA phylogeny study by ŠtundlovÁ et al. (2019) . We confirm that males indeed have a higher Dp value than A. alpha (8 vs. 7), Pv varies between 5 and 6, and reduction of et from 4 to 3 is rare (ca. 2%, only one case out of 46 scored pedipalps).
