Geographic distribution. Southern Turkey: Antalya Province (see map in Fig. 28).

Etymology. The specific epithet honors Dr. Bayram Göçmen, a Turkish herpetologist.

Diagnosis. A medium small Euscorpius species , total length 25–30 mm (average 27.29 mm). Color very light brownish-ivory to brownish-reddish with darker chelae, without marbling. The mesosoma may be more dark, greyish, due to the translucent cuticle. Number of trichobothria on pedipalp manus ventral surface is 4 (3 V + Et 1). Trichobothrium et on fixed finger is located distally to the notch of the fixed finger; est is located proximally or above the notch; and dsb is located proximally to the notch. Number of trichobothria on the pedipalp patella ventral surface usually is 11 to 12 (10 in 2.78 %, 11 in 38.89 %, 12 in 50 % and 13 in 8.33 % of pedipalps examined). Number of trichobothria on pedipalp patella external surface is: eb = 4, eba = 4, esb = 2, em = 4, est = 4, et = 7 to 8 (series et = 7 in 36.11 %, 8 in 61.11 % of pedipalps examined). Pectinal teeth count is 10 to 12 in males (10 in 46.15 %, 11 in 42.31 % and 12 in 11.54 % of the pectines examined) and usually 8 in females (8 in 75.00 % and 9 in 25.00 % of the pectines examined). Chela with a well-developed notch on fixed finger and lobe on movable finger in males, obsolete in females. Lchel/Wchel ratio is 2.521 in males and 2.745 in females. Dorsal patellar spur well-developed. Femur longer than patella; Lfem/Lpat ratio is 1.042. Carapace may be slightly longer than wide to slightly wider than long; average ratio Lcar/Wcar 1.006; average distance from center of median eyes to anterior margin of the carapace is 42.46 % of the carapace length. Average distance from center of median eyes to posterior margin of the carapace is 57.54 % of the carapace length. Average ratio of Lmet/Lcar is 2.555 in males and 2.198 in females.

Trichobothrial and pectinal teeth count variation. Variation observed in 18 studied specimens (14 males, 4 females) is given below.

Pectinal teeth, males (n=14): 10/10 (5), 4/11 (1), 10/11 (1), 11/? (1), 11/10 (1), 11/11 (3), 12/11 (1), 12/12 (1); in total, 10 in 46.15 %, 11 in 42.31 % and 12 in 11.54 %; mean = 10.65, SD = 0.67

Pectinal teeth, females (n=4): 8/8 (3), 9/9 (1); in total, 8 in 75 %, 9 in 25.50 %; mean = 8.25, SD = 0.43.

Pedipalp patella, ventral trichobothria Pv (n=18): 11/10 (1), 11/11 (6), 11/12 (1), 12/12 (7), 12/13 (1), 13/12 (2); in total, 10 in 2.78 %, 11 in 38.89 %, 12 in 50 % and 13 in 8.33 %; mean = 11.64, SD = 0.67.

Pedipalp patella, external trichobothria Pe (n=18): et = 6/7 (1), 7/7 (4), 8/7 (4), 8/8 (9); in total, 6 in 2.78 %, 7 in 36.11 %, 8 in 61.11 %; mean = 7.58, SD = 0.55; est = 4/3 (1), 4/4 (17); em = 4/4 (18); esb = 2/2 (18); eba = 4/4 (18); eb = 4/4 (18).

Hemispermatophore. Both right and left hemispermatophore of 4 specimens were studied. They have a well-developed lamina tapered distally; well-developed basal constriction present; truncal flexure present; median projection with primary and secondary acuminate processes; internal projection distally show 8–13 tines in its crown. The number of tines of the crown may differ between specimens and between the right and the left hemispermatophores.
