  Type material. Holotype : ♀, Croatia: Korčula Island, Vrbovica, April 1999 (UL).   
 Paratypes: Croatia: Lapad Peninsula, May 1952, 1 ♀ (UL); Cavtat (Ragusavecchia), 1 ♂ imm. (MZUR 35). Bosnia & Herzegovina: Republika Srpska, Trebinje, 1 ♀ (UL); Petrina, Trebinje, 6 June 2004, leg. D. Pavic, 1 ♀ imm. (VFPC); Zavala, 1 ♂ imm. (GTC). Unclear locality (see Reitter, 1881): “ Dalmatien: Castelnuovo, Ragusa, Dricno” [Croatia: Ragusa (now Dubrovnik). – Bosnia & Herzegovina: Drieno (now Drijen, on the road Dubrovnik– Trebinje). – Montenegro: Castelnuovo (now Herceg Novi), April-May] 1880, leg. [E.] Reitter, 1 ♀ (NHMW 13289).   
 Note: The precise provenance of the specimens NHMW 13289 is not known. The label says “Yu / Dalmatien: Castelnuovo, Ragusa, Dricno, leg. Reitter 1880.” Consulting Reitter (1881), we can say that Cas- telnuovo refers to the city Herceg Novi, northern Mon- tenegro, near the border with Croatia; Ragusa refers to Dubrovnik, in southern Croatia; while Dricno is misspelled Drieno, an old Turkish fort in Bosnia & Herzegovina, on the road to Trebinje. Unfortunately, Reitter (1881) did not mention where exactly these scorpions were collected. The three localities are all quite close, thus all specimens NHMW 13289 (including E. tergestinus and E. hadzii) could come from any of these places.   
  Geographic distribution:  Western Balkans: Bosnia & Herzegovina (west), Croatia (south),?Montenegro (northwest) (see map in Fig. 17).   
 Etymology: The specific epithet in honor of the scorpiologist Victor Fet, who has provided and continues to provide a great contribution to the knowledge of the genus Euscorpius, and for his willingness to help his colleagues.   
 Diagnosis: Amedium-large Euscorpius species, total length 35–38 mm. Color of adults light brownreddish, carapace and pedipalps darker reddish. More or less expressed reticulation or marbling on carapace, metasoma and chelicerae is present. The number of trichobothria on the pedipalp manus ventral surface is 4 (3 V + Et 1); the number of trichobothria on the pedipalp patella ventral surface is 11 to 12 (11 in 71.43% and 12 in 28.57% of pedipalps examined); the number of trichobothria on pedipalp patella external surface is usually: eb = 4,  eba  = 4, esb = 2, em = 4, est = 4, et = 8 (series et = 8 in 85.71 % and et = 7 in 14.29 % of pedipalps examined). Trichobothria et 2 and est 2 on pedipalp patella external surface are located in a very proximal position; trichobothrium et 2 is proximal to est 3. The pectinal teeth count is 9 in males and usually 7 in females (7 in 80 % and 8 in 20 % of pectines examined). Metasomal segment Iusually longer than wide or as long as wide; average L/W ratio 1.029. Lchel/Wchel ratio is 3.294 in females. Dorsal patellar spur highly developed. Femur longer than patella; Lfem/Lpat ratio is 1.077. Carapace usually longer than wide; average ratio Lcar/Wcar 1.053; average distance from center of median eyes to anterior margin of the carapace is 38.80 % of the carapace length. Average distance from center of median eyes to posterior margin of the carapace is 61.20 % of the carapace length. Average ratio of Lmet/Lcar is 2.226.   
  Trichobothrial and pectinal teeth count variation:  The variation observed in 7 studied specimens (2 males, 5 females) is given below (left/right asymmetry not specified). Pectinal teeth in males (n=2): 9/9 (2). Pectinal teeth in females (n=5): 7/7 (4), 8/8 (1); in total, 7 in 80.00 % and 8 in 20.00 %; mean = 7.20, SD = 0.40. Pedipalp patella trichobothria Pv (n=7): 11/11 (3), 11/12   
 (4); in total, 11 in 71.42 % and 12 in 28.58 %; mean = 11.28, SD = 0.45. Pedipalp patella trichobothria Pe (n=7): et = 7/7 (1), 8/8 (6), in total, 7 in 14.29 % and 8 in 85.71 %; mean = 7.86, SD = 0.35; est = 4/4 (7); em = 4/4 (7); esb = 2/2 (7);  eba  = 4/4 (7); eb = 4/4 (7).
