(Figures 1–6)
Diagnosis. This new species belongs to the kuznetzovi species group as defined by Chant & McMurtry (2003), because setae JV4 are present. Dorsal shield reticulated; bearing three pairs of solenostomes (gd2, gd6, and gd9). Dorsal setae j3, z2, z4, Z1, Z4, Z5, s4, S2, and sub-lateral setae r3 serrated in their apical half and each has a small apical knob. Remaining dorsal setae smooth and sharp pointed. Peritreme short, extending to level of z4 setae. Genu II with eight setae; one pair of solenostomes posteromedian to JV2; sternal shield with three pairs of setae; fixed digit of chelicera with two teeth and movable digit without teeth.
Female (n=11). Dorsum (Figure 1). Dorsal setal pattern 10A:8C (r3 and R1 off shield). Dorsal shield oval with a waist at level of R1, sclerotised, strongly reticulated, lines running parallel to length of the shield. Shield with three pairs of rounded solenostomes (gd2, gd6 and gd9). Muscle-marks (sigilla) visible on podosoma, length of dorsal shield (j1–J5) 318 (310–325), width (distance between bases of s4) 147 (140–155), width (distance between bases of S2) 161 (155–165). Dorsal setae j3, z2, z4, Z1, Z4, Z5, s4, S2, and sub-lateral setae r3, which are longer than 40 µm, serrated in their apical half, each with a small apical knob. Other dorsal setae shorter than 20 µm, smooth and sharp pointed. Measurements of dorsal setae as follows: j1 16 (15–18), j3 41 (40–43), j4 17 (16– 19), j5 13 (13–14), j6 16 (13–18), J2 16 (15–18), J5 6 (5–7), z2 41 (40–43), z4 43 (40–45), z5 13 (13–15), Z1 41 (38–43), Z4 41 (38–44), Z5 41 (40–43), s4 53 (50–54), S2 50 (50–53), S5 8 (7–10), r3 45 (43–46) and R1 18 (17– 19).
Peritreme. Short, and extending to level of setae z4.
Venter (Figure 2). Ventral setal pattern 13 JV -3: ZV -3. Sternal shield smooth, lightly sclerotised; bearing three pairs of setae (ST1, ST2 and ST3) and two pairs of pores (Pst1 and Pst2); length (ST1–ST3) 67 (65–70), width (distance between setae ST2) 53 (50–55); metasternal setae ST4 and a pair of pores (Pst3) on metasternal shields. Genital shield smooth; width at level of genital setae (ST5) 51 (49–53). Ventrianal shield elongated with a waist at level of pre-anal pores; conspicuously wider at anus level than at level of setae JV1; transverse striations are visible in pre-anal and anal area. In most specimens, the ventrianal shield has three pairs of pre-anal setae (JV1, JV2 and ZV2), but in two paratype specimens, seta ZV2 was outside the shield on the left side. A pair of para-anal (Pa) and a post-anal setae (Pst); a pair of small pores (gv3) posterior to JV2, distance between pre-anal pores 22, and muscle-marks posterolaterally. Length of ventrianal shield 98 (95–100), width at level of setae JV1 47 (45–50), width at level of anus 59 (55–63). Setae ZV1, JV4 and JV5 and seven pairs of pores on integument surrounding ventrianal shield. Setae JV5 smooth 16 (15–18) in length; not markedly longer than other ventral setae.
CheliCera (Figure 3). Fixed digit 23 long with two apical teeth and pilus dentilis; movable digit 20 long without tooth. A membranous structure known as the gnathobrachium is present between the gnathosoma and idiosoma (Figure 6).
SPermatheCa (Figure 4). Calyx cup-shaped 6 (5–8) in length; atrium knobbed; major duct long; minor duct visible.
Legs (Figure 5). Length of legs (basis of coxae to basis of claws): leg I 253 (245–260); leg II 202 (190–220); leg III 177 (165–185); leg IV 248 (245–250). GeII, GeIII and GeIV with eight, seven and seven setae, respectively; StIV with a short macroseta 15 in length.
Male. Unknown.
Type material. Holotype female and seven paratype females, Kovada Lake National Park, Isparta Province, October 25, 2016, on Phlomis sp. (Lamiaceae), three paratype females, June 2, 2017, on the same host and locality. The holotype female and 9 paratype females are deposited in the mite collection of the Acarology Laboratory, Department of Plant Protection, Çukurova University, Adana, Turkey. One female paratype will be deposited in the Natural History Museum, London, UK.
Etymology. This new species is named in honor of Prof. Dr. Kamil Karut (Cukurova University, Agricultural Faculty, Department of Plant Protection, Adana, Turkey), a prominent whitefly specialist.
Remarks. This new species belongs to the kuznetzovi species group, because setae JV4 are present. Differences between Eharius karuti and the other members of the kuznetzovi species group are given in Table 1 and Table 2. In their revision of the tribe Kampimodromini Kolodochka, Chant & McMurtry (2003) mentioned that Eharius species do not have the dorsal setae serrated but rather setiform and whip-like (except for Z5). However, this new species has dorsal setae j3, z2, z4, Z1, Z4, Z5, s4, S2, and r3 serrated in their apical half and knobbed apically. Many other morphological characters such as the absence of S4 and ZV3, dorsal reticulation running parallel to length of the shield, cup-shaped calyx of spermatheca, short peritreme, a few teeth on fixed digit, and smooth movable digit, are identical to the genus Eharius.
