Euscorpius aquilejensis (C. L. Koch, 1837) , stat. nov.

Scorpius aquilejensis C. L. Koch, 1837: 101-103 , pl. CV, Fig. 244.

Holotype (male; presumed lost), surroundings of Trieste, Italy (leg. Wagner).

The neotype is designated here according to ICZN Article 75 as it is required for the purposes of clarifying the taxonomic status of specific populations.

Neotype: male, Aquileia, Udine, Friuli-Venezia

Giulia, Italy, 1978, leg. Marinoni ( MZUF 6269).

Notes:

(1) Fet & Soleglad (2002) assigned a neotype for E. tergestinus from Osp, in Slovenia ( NHMW), near the border with Italy. We found, however, that this specimen belongs to the species E. aquilejensis stat. nov. as evidenced by all the trichobothrial series, the pectinal teeth count and the measurements reported in Fet & Soleglad (2002). Also the pictures of specimens of E. tergestinus from Strunjan and Osp in Slovenia show clearly the typical diagnostic characters of E. aquilejensis stat. nov. Thus the Osp neotype is declared invalid herein according to Article 75 of the ICZN.

(2) The populations considered as E. tergestinus in Vignoli et al. (2005, 2007), Salomone et al. (2006), Tropea (2012) and Tropea et al. (2012) belong to E. aquilejensis .

Diagnosis: A medium-large Euscorpius species , total length 29-41 mm. Color of adults yellowish-ivory to light brown-reddish with carapace and pedipalps darker, reddish. Without reticulations or marblings on all body parts, especially on chelicerae. Slender appearance with carapace, metasoma and all segments of the pedipalps elongated. Trichobothria db and dsb are located much more distally than the base of the fixed finger; trichobothrium db is distal to eb and esb; and trichobothrium esb is distal to eb. 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 usually is 9 (in 91.38% of examined pedipalps); the number of trichobothria on pedipalp patella external surface is: et = 6 (in 93.04% of examined pedipalps), est = 4, em = 4, esb = 2, eba = 4, eb = 4. The pectinal teeth count usually is 8 in males (in 89.13% of pectines examined) and 7 in females (in 85.71% of pectines examined). The telson vesicle in males is more swollen than in females: average L/H ratio of the vesicle is 1.73 (min. 1.67, max. 1.91) in male and 1.96 (min. 1.83, max 2.12) in females. Chela with a notch on fixed finger and scalloping of the movable finger in adult males, obsolete in females; Lchel/Wchel ratio is 2.79 in males and 2.89 in females. Dorsal patellar spur very developed. Femur longer than patella; Lfem/Lpat ratio is 1.05. Average ratio Lcar/Wcar is 1.10; average value of the length from center of median eyes to anterior margin of the carapace is 38.88% of the carapace length. Average value of the length from center of median eyes to posterior margin of the carapace is 61.12% of the carapace length. Average ratio of Lmet/ Lcar is 2.53 in males and 2.31 in females.
