Diagnosis. Idiosomal setal pattern 10A:8C/ JV –3: ZV ( r3 and R1 off shield). Dorsal shield sclerotized, mostly striated; with slight waist at level of R1; with five pairs of solenostomes ( gd1, gd2, gd6, gd8, and gd9); dorsal setae serrated except j4, j5, j6, J2, z5 and Z1 smooth. Peritremes extending between setae j3-z2. All ventral shields smooth, except ventrianal shield with a few posterior striations; sternal shield with three pairs of setae; ventrianal shield elongated, with three pairs of preanal setae and a pair of minute preanal solenostomes located posteromesad to setae JV2; seta JV5 serrated. Spermatheca with short, cup-shaped calyx and nodular atrium, attached to calyx without neck. Fixed digit of chelicera with three subapical teeth and movable digit without tooth. Leg IV with one serrated macroseta. Genu II and IV each with eight (2 2/1 2/0 1) setae and tibia IV with seven setae (1 1/1 2/0 2).

Re-description

Female (n=4).

Dorsal idiosoma ( Fig. 1A ). Dorsal setal pattern 10A: 8C ( r3 and R1 off shield). Dorsal shield mostly striated, with slight waist at level of seta R1, with five pairs of solenostomes ( gd1, gd2, gd6, gd8 and gd9). Muscle-marks (sigillae) visible mostly on podosoma; length of dorsal shield 282 (280–284), width at level of s4 160 (156–163), width at level of S2 164 (163–165). Dorsal setae serrated, except j4, j5, j6, J2, z5 and Z1 smooth. Measurements of dorsal setae as follows: j1 20 (18–21), j3 27 (25–30), j4 15 (13–17), j5 14 (12–15), j6 16 (14–18), J2 20 (17–23), J5 8 (6–9), z2 25 (24–26), z4 34 (32–37), z5 16 (14–18), Z1 21 (18–24), Z4 40 (37–43), Z5 52 (49–55), s4 43 (38–47), S2 44 (40–48), S5 18 (17–20), r3 40 (38–42), and R1 25 (23– 27). Peritremes extending between setae j3-z2.

Ventral idiosoma ( Fig. 1B ). Ventral setal pattern 14: JV–3: ZV. Sternal shield smooth, with three pairs of setae ( ST1– ST3) and two pairs of poroids ( iv1, iv2); distance between bases of setae ST1–ST3 59 (56–61), distance between bases of setae ST2 56 (55–58); metasternal setae ST4 and poroids iv3 on metasternal shields. Genital shield smooth with one pair of setae ST5; width at level of ST5 49 (48– 50); one pair of para-genital poroids iv5 on soft cuticle. Ventrianal shield elongate, mostly smooth except for some posterior striations, with three pairs of pre-anal setae ( JV1, JV2, and ZV2), one pair of para-anal setae PA, unpaired post-anal seta PST, and a pair of minute solenostomes ( gv3) posteromedian to JV2. Length of ventrianal shield 92 (89–94), width at level of ZV2 54 (50–58). Four pairs of caudoventral setae ( ZV1, ZV3, JV4 and JV5) and six pairs of poroids (five ivo and ivp) on soft cuticle surrounding ventrianal shield. Setae JV5 serrated, 35 (34– 35) in length.

Chelicera ( Fig. 1C ). Fixed digit 24 (23–25) long, with three teeth clustered sub-apically and pilus dentilis; movable digit 24 (23–25) long, without tooth.

Spermatheca ( Fig. 1D ). Calyx short, cup-shaped, 8 (6–10) long, atrium nodular, connected to calyx without neck, major duct long, narrow, minor duct visible.

Legs ( Figs 2 A-D). Leg I 262 (260–264), II 209 (205–213), III 195 (190–200), IV 279 (265–286) in length. Chaetotaxy of legs as follows: Leg I: coxa 0 0/1 0/1 0, trochanter 1 0/1 0/2 1, femur 2 3/1 2/2 2, genu 2 2/1 2/1 2, tibia 2 2/1 2/1 2. Leg II: coxa 0 0/1 0/1 0, trochanter 1 0/1 0/2 1, femur 2 3/1 2/1 1, genu 2 2/1 2/0 1, tibia 1 1/1 2/1 1. Leg III: coxa 0 0/1 0/1 0, trochanter 1 1/1 0/2 0, femur 1 2/1 1/0 1, genu 1 2/1 2/0 1, tibia 1 1/1 2/1 1. Leg IV: coxa 0 0/1 0/0 0, trochanter 1 1/1 0/2 0, femur 1 2/1 1/0 1, genu 2 2/1 2/0 1, tibia 1 1/1 2/0 2. Leg IV with one macroseta StIV ( pd3) 22 (21–23), usually with two barbs, smooth in one specimen. Other legs without macrosetae.

Male. Not collected in this study.

Material examined. Four females from hazelnut, C. avellana in Gürgenyatak village , Canik , Samsun, Türkiye (41° 13' 32 "N, 36° 21' 50" E, 513 meters above sea level); collected by S.K. Ozman-Sullivan and G.T. Sullivan on 01 October 2021 .

Discussion. Kampimodromus corylosus was described from specimens mostly collected from hazelnut, C. avellana , in Ukraine and Moldova. The current study reports K. corylosus for the first time from Türkiye. The morphological characters and measurements of the newly collected specimens are almost identical to the original description and redescriptions ( Cargnus et al., 2012; Döker et al., 2022). We re-examined the Belgian specimens reported by Döker et al. (2022) and confirm that the measurements of dorsal seta j3 are not 21 (21–22) but 31 (31–32). Also, the preanal solenostomes in the Belgian specimens are small and circular, not crescentic, as in the original description and the redescription provided here.
