Distances between ST1 – ST3 61 (48–65), ST2 – ST2 58 (53–73), ST5–ST5 55 (53–60). Two pairs of metapodal plates 28 (25–30) long, 4 (3–5) wide for the largest and 14 (13–15) long, 2 (2–3) wide for the smallest. Ventri-anal shield reticulated with four pairs of pre-anal setae, JV1, JV2, JV3 and ZV2, and no pre-anal pores. Membrane surrounding ventri-anal shield with four pairs of setae ZV1, ZV3, JV4 and JV5, and four pairs of round to oblong poroids; ventri-anal shield 113 (108–118) long, 94 (90–103) wide at anterior corners, and 89 (85–93) wide at level of anus. JV5 79 (75–83) long. A pair of lyrifissures near JV5.

Legs. Legs IV with a macroseta on the basitarsus 45 (40–48). Chaetotactic formula of genu II: eight setae 2 2/ 1, 2/0 1; genu III: seven setae, 1 2/1, 2/0 1. Length of leg I: 352 (350–355), II: 269 (250–290), III: 270 (265–270), IV: 307 (300–315).

Chelicera ( Fig. 34 ). Fixed digit 30 long with three teeth; and movable digit 28 long with one tooth. Pilus dentilis not visible.

Spermatheca ( Fig. 35 ). Saccular shaped ( Denmark et al., 1999), with a cervix elongate 18 (16–20) long and 8 wide, with a neck between atrium and calyx.

Etymology. The name “ mazarii ” refers to the locality where the new species was found.

Description of the adult male (n = 2) ( Figs 36–38 )

Dorsum ( Fig. 36 ). Dorsal shield 265, 280 long and 200, 205 wide, with five solenostomes (gd2, gd4, gd6, gd8 and gd9). The dorsal shield bears 18 pairs of dorsal setae and 2 pairs of sub-lateral setae: j 1 23, 25; j3 33, 35; j4 20; j 5 20, 22; j 6 25, 28; J2 35; J5 8; z2 23; z 3 25, 28; z 4 25, 30; z 5 23, 25; Z4 55; Z5 65, 68; s4 35; s6 40; S2 45; S4 33, 35; r 3 30, 33; R1 30. All setae smooth except Z5 serrated. Peritreme short, extending to z2 ( Fig. 36 ).

Venter ( Fig. 37 ). All shields very lightly reticulated. Distances between ST1 – ST3 63, ST2 – ST2 50, ST5–ST5 38, 42. Ventri-anal shield with five pairs of pre-anal setae, ZV1, JV1, JV2, JV4 and ZV2, and no pre-anal pores. Membrane surrounding ventri-anal shield with one pair of setae JV5; ventri-anal shield 110 long; 145, 148 wide at anterior corners and 78, 80 wide at level of anus. JV5 40 long. A pair of lyrifissures near JV5.

Legs. Legs IV with three macrosetae GeIV 15, STiIV 15, basitarsus ST IV 35, 40. Chaetotactic formula of genu II and III similar to females.

Chelicera ( Fig. 38 ). Fixed digit 15 ong, movable digit 2 long (dentition not visible, chelicera closed). Spermatodactyl lance-shaped.

Remarks. This species is similar to T. (T.) octogenipilus , T. (T.) sirikariensis Kapaxidi & Papadoulis and Typhlodromus (Typhlodromus) antakyaensis Stathakis & Döker in bearing four solenostomes on the dorsal shield, no pores on the ventri-anal shield and eight setae on the genu II. However, dorsal setae and ST IV are much longer in T. (T.) mazarii than for those two former species ( Table 5 ). For a great majority of setae, the difference between the new species and the others are much higher than 14 µm, proposed by Tixier (2013) to be the threshold between intra and interspecific variations for continous characters like seta lengths.

It is interesting to note that females bear four solenostomes (absence of gd4) suggesting that this character is variable and may be not diagnostic as suggested for solenostome gd2 by Tixier et al. (2011) for two species of the genus Neoseiulus .
