First records of water mites (Acari: Hydrachnidia) from Bhutan, with description of two new species Author Pesic, Vladimir Author Smit, Harry text Zootaxa 2007 1613 45 56 journal article 10.5281/zenodo.178993 47088b53-41a2-4c58-b39e-2904ac4369a8 1175-5326 178993 Testudacarus tripeltatus Walter, 1928 ( Figs. 15–20 ) Material examined. Bhutan : Dochu La, 06.iv.2002 , 2800 m asl., two females ( ZMAN ), one of them dissected and slide mounted in Hoyer's fluid. Morphology. Female : Idiosoma (ventral view: Fig. 16 ) L 856, W 650; dorsal shield ( Fig. 15 ): central plate L 556, W 469, L/W ratio 1.19, single median anterior plate L 144; capitular bay L 172, Cx-1 total L 294, Cx-1 medial L 122, Cx-2+3 medial 62; ratio Cx-1 L/Cx-2+3 medial L 2.4; Cx-1 medial L/Cx-2+3 medial L 4.7; genital field L/W 181/147, L/W ratio 1.2; distance genital field–excretory pore 247, genital field–caudal idiosoma margin 308; capitulum ( Fig. 19 ) ventral L 167; chelicera L ( Fig. 20 ) 196, H 26 L/H ratio 7.6, basal segment L 161, claw L 38, L claw/basal segment ratio 2.4; palp ( Figs. 17–18 ) total L 206, dL and %L (in parentheses, given as % of total L): P-1 32 (15.5), P-2 61 (29.6), P-3 43 (20.9), P-4 53 (25.7), P-5 17 (8.3); P- 2/P-4 ratio 1.15. Remarks. T . tripeltatus is similar to T. okadai Imamura (known from Japan ) due to the short median suture of Cx-2+3 (<0.5 the length of the genital flap) ( Wiles 1997 ). Dorsolateral platelets are large and broad in T. tripeltatus but small and narrow in T. okadai . The specimen from Bhutan differs from the specimen from India (in parentheses data taken from Walter 1928 ) in its minor idiosomal and capitular dimensions (e.g., idiosoma L/W 1065/720, central plate L/W 690/525, capitulum L 220, chelicera L 225, palp total L 223). Distribution. India ( Walter 1928 ). New for Bhutan .
