Due to the characteristic shape of the integument, Sperchon bakeri nov. sp. is similar to S. lepidophorus Lundblad, 1941 described by Lundblad (1941) from a female specimen collected in Burma, from which it is easily distinguished by the following features (for detailed description of S. lepidophorus see Lundblad 1967): anterior margins of Cx- 1 with rather long plumose setae vs. without the long plumose setae in S. lepidophorus, P- 3 ventral margins with one thin seta vs. in S. lepidophorus without seta, P- 4 ventral margin with 2 small tubercles situated in the middle part of the segment vs. distanced from each other with distoventral one closely approached to the distoventral edge margin of the segment in S. lepidophorus. Etymology. The species is named after Dr Richard Baker (UK). Habitat. Discovered in mosses in a mountain stream. Distribution.

Schwoerbel & Panesar. Diagnosis. Dorsal integument: lineated; muscle attachments: unsclerotized; medial suture Cx- 1 + 2 relatively long; genital field: Ac in an obtuse triangle; P- 2 and - 3 with ventral protrusions; I-Leg: I-Leg- 5 thickened (L/HB 2.03), S- 1 and – 2 narrow interspace, S- 1 with truncate tip, S- 2 shortened, with a blunt tip.

Both species have the ventral surface covered by an extended shield including coxae, Vgl- 3 and - 4 and genital field, and the similar shape of I-Leg- 5 and - 6. A. lahauli sp. nov. can be easily distinguished from A. dorsoscutatus in the absence of dorsal shield vs. presence of dorsal shield in A. dorsocutatus, smooth excretory pore vs. surrounded by sclerotized ring in A. dorsoscutatus, and Vgl- 1 and - 2 incorporated into the posterior end of the ventral shield vs. Vgl- 1 and - 2 not fused with the ventral shield in A. dorsoscutatus. Etymology. The species is named after the area where it was collected. Habitat. Discovered in mosses in a mountain stream. Distribution.

Palp (Fig. 8 C): palp total L 205, dL and %L (in parentheses): P- 1 23 (11.2), P- 2 48 (23.4), P- 3 50 (24.4), P- 4 65 (31.7), P- 5 19 (9.3); L P- 2 /P- 4 0.74; P- 3 ventral margins straight, P- 4 with weakly developed denticles near hair insertions, sword seta between ventral hair insertions, approached to distoventral hair. Genital field (Fig. 8 B): fused with the ventral shield, but suture lines still evident, W 98, L Ac- 1-3: 25 - 17-19; excretory pore smooth; Vgl- 1 and - 2 incorporated into the posterior end of the ventral shield. I-Leg (Fig. 8 D): I-Leg- 5 with dorsal and ventral margins only weakly diverging distally, S- 1 and – 2 with narrow setal interspace, homeomorphic, bluntly pointed; I-Leg- 6 short and stout, weakly curved, with maximum H at the base of the claw furrow; I-Leg- 5 dL 102, vL 78, dL/vL 1.3, HB 27, dL/HB 3.8, S- 1 L 34, L/ W 11.3, S- 2 L 31, L/ W 10.3, distance of sword setae at I-Leg- 5 2.0; L S- 1 / 2 1.1; I-Leg- 6 L 71, HB 24, L/HB 3.0; L I-Leg- 5 / 6 1.44. Female: unknown. Discussion. The new species is similar to Atractides dorsoscutatus Cook, 1967 described by Cook (1967) from Kerala State (India). Both species have the ventral surface covered by an extended shield including coxae, Vgl- 3 and - 4 and genital field, and the similar shape of I-Leg- 5 and - 6. A. lahauli sp. nov. can be easily distinguished from A. dorsoscutatus in the absence of dorsal shield vs. presence of dorsal shield in A. dorsocutatus, smooth excretory pore vs. surrounded by sclerotized ring in A. dorsoscutatus, and Vgl- 1 and - 2 incorporated into the posterior end of the ventral shield vs. Vgl- 1 and - 2 not fused with the ventral shield in A. dorsoscutatus. Etymology. The species is named after the area where it was collected. Habitat. Discovered in mosses in a mountain stream. Distribution. Known only from the type locality in Himachal Pradesh State.Published as part of Pesic, Vladimir & Panesar, Arne, 2009, Studies on water mites (Acari, Hydrachnidia) from the Himalayas, II.
