Description.
Female (n = 3): Idiosoma elliptical, L 847 (774-887), W 586 (586-648), L/W ratio 1.4 (1.3-1.4). Dorsal plate 4+1 (Fig. 1A View Figure 1 ), dorsal shield L 755 (682-770), W 530 (530-585), dorsal plate L 694 (620-709), frontal platelets L 158 (152-170), W 83 (69-90), shoulder platelets L 169 (169-196), W 99 (81-99). Infracapitular bay U-shaped, depth 126 (126-150); only the tip of Cx-I exceeding to the anterior margin of idiosoma; Cx-I L 270 (230-273), mL 123 (102-123), Cx-II+III mL 33 (19-33); Gf pentagonal, L 220 (180-220), W 168 (168-192), L/W ratio 1.3 (1.1-1.3), distance between Gf and Ap 220 (156-220); E4 at the same level as the 6th pair of acetabula; Ap away from the line of primary sclerotization, on the same level of V1 and anterior to V2 (Fig. 1B View Figure 1 ). Gnathosoma (Fig. 1D View Figure 1 ): the lateral view of gnathosoma regular triangle-like; vL 231 (200-242), dL 151 (128-159), chelicera bs L 214 (202-251), claw L 41 (41-43). P-1 with one dorsal seta; P-2 with one dorsal and one ventral setae at the base of the ventral extension; P-3 with three dorsal setae and one long seta at the base of the ventral extension; P-4 with one dorsal seta in proximal half, two mediodistal setae and two ventral setae at the slight ventral extension (Fig. 1C View Figure 1 ). dL of palp segments: P-1, 27 (26-30); P-2, 68 (65-68); P-3, 41 (37-48); P-4, 62 (59-72); P-5, 20 (19-25). Legs (Fig. 2 View Figure 2 ): dL of leg segments: I-L-1-6: 64 (64-74), 86 (86-87), 84 (82-92), 109 (105-123), 124 (116-124), 125 (115-125); II-L-1-6: 51 (44-51), 92 (89-116), 78 (76-86), 110 (110-132), 129 (129-149), 132 (127-142); III-L-1-6: 73 (54-73), 80 (80-108), 82 (72-86), 123 (105-123), 139 (107-139), 146 (121-146); IV-L-1-6: 126 (115-134), 119 (111-123), 118 (112-133), 169 (157-185), 169 (165-192), 167 (148-174).
Male. Unknown.
Habitat.
Streamlet.
Remarks.
Due to the characteristic shape of gnathosoma and dorsal shield (i.e., gnathosoma with a short rostrum, the lateral view of gnathosoma regular triangle-like), this new species is similar to Torrenticola siamis Pešić & Smit, 2009 ( Pešić and Smit 2009). However, there are obvious differences between them: (1) only the tip of Cx-I exceeding to the anterior margin of idiosoma in this new species, but the tip of Cx-I and Cx-II exceeding in T. siamis ; (2) E4 at the same level as the 6th pair of acetabula in the new species, but the 4th pair in T. siamis ; (3) D2 on the same level with muscle scars in the new species, but D2 anterior to muscle scars in T. siamis .
Etymology.
The specific name is from Latin affix: " pseudo -", which means fake or simulated; this new species is named after its similar species, T. siamis .
Distribution.
China (Zhejiang).
