Typhlodromus (Typhlodromus) tulinae sp. nov. Döker is described based on specimens collected from Carpinus betulus L. (Betulaceae) in Ordu Province on the Black Sea coast, Turkey. The new species can be easily distinguished from all known species of the subgenus by the combination of the following morphological characters: dorsal shield with three pairs of solenostomes (gland pores), peritreme extending to region between j3 and z2, sternal shield with two pairs of setae, ventrianal shield with four pairs of preanal setae and no preanal solenostomes, movable digit of chelicera with two teeth, genu II with eight setae, and spermatheca with large bulbous atrium and saccular calyx. A key to separate the Turkish species of the subgenus is also provided.
