Etymology. The name parapresentalis is derived from the closely related species Syringophiloidus presentalis .

Differential diagnosis. This new species is morphologically similar to Syringophiloidus presentalis . In females of both species the chambers of lateral branch of the peritremes are with striae ornamentation; the hysteronotal shield is weakly marked and apunctate; setae si are longer than 100; dorsal setae are thin and very slightly ornamented. The both species are distinguished as follows: in females of S. parapresentalis , the total body length is 605–645; the lengths of the stylophore and the movable cheliceral digit are 155–160 and 120–125 respectively; the length ratio of setae vi: si is 1:4–4.5; in males, the total body length is 405–430; the lengths of the stylophore and the movable cheliceral digit are 130–135 and 115–120, respectively; the length ratio of setae vi: si is 1:4–4.5; the hysteronotal shield is absent, aggenital setae ag1 are 1.4–1.6 times longer than ag2; setae 3c are 3 times longer than 3b. In females of S. presentalis , the lengths of the stylophore and the movable cheliceral digits are 195–200 and 150– 155, respectively; the length ratio of setae vi: si is 1:6.5; in males, the total body length is 580–605; the lengths of the stylophore and the movable cheliceral digits are 155 and 150 respectively; the length ratio of setae vi: si is 1:2– 2.5; the hysteronotal shield is present; aggenital setae ag1 are 2–2.2 times longer than ag2; setae 3c are twice as long as 3b.
