Female, dorsal shield; 33. Female, ventral idiosoma; 34. Female, chelicera; 35. Female, spermatheca; 36. Male, dorsal shield; 37. Male, ventral idiosoma; 38. Male, spermatodactyl. 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 .
