Description
Female (n = 1) – Idiosoma elliptical, L 589, W 428, L/W ratio 1.4. Dorsal plate 4+1 (Figure
9A), dorsal shield L 453, W 378, dorsal plate L 409, frontal platelets L 109, W 61, shoulder platelets L 182, W 75. Infracapitular bay U-shaped and wide, depth 134; Cx-I L 247, mL
115, Cx-II+III mL 26; genital field L 171, W 151, distance between genital field and Ap 94; Genital field L/W ratio 1.1; E 4 at the same level as the 4 th pair of acetabula; the line of primary sclerotization absent, and Ap posterior to V 1 and V 2, ( Figure 9B View Figure 9 ). P-1 and P-2 dorsal setae absent, P-2 with one ventral seta on the ventrodistal prolongation; P-3 with two dorsal setae and one ventrodistal prolongation with one long seta on it; P-4 with one dorsal seta and two ventral setae ( Figure 9C View Figure 9 ). Gnathosoma ( Figure 9D View Figure 9 ) dorsal apodeme almost absent, ventral apodeme blunt and long, rostrum flat and parallel to the ventral apodeme; vL 256, dL 211, chelicera bs L 249, claw L 44. L of palp segments: P-1, 43; P-2, 102; P-3, 66; P-4, 86; P-5, 10. Legs ( Figure 9E–H View Figure 9 ): L of leg segments: I-L-1–6: 40, 53, 46, 60, 62, 74; II-L-1–6: 40, 60, 46, 61, 62, 78; III-L-1–6: 43, 77, 49, 63, 80, 91; IV-L-1–6: 87, 86, 77, 102, 112, 104.
Male – Unknown.
Habitat — Ditch, about 1 m wide, 0.2–0.3 m depth, with many small stones at the bottom.
Remarks — Torrenticola planusirostrum sp. nov. is characterized by dorsal apodeme almost absent, ventral apodeme blunt and long, rostrum flat and parallel to the ventral apodeme. In addition, P-1 and P-2 dorsal setae absent. Although we only have one specimen, because of its unique gnathosoma shape, we considered this is a new species.
Etymology — The specific epithet is neuter in gender and derived from Latin words, planus
= flat, and rostrum = beak and refers to flat rostrum, parallel to the ventral apodeme; used as a noun in apposition.
Distribution — China (Jiangxi).
