Amblyseiulella amanoi Ehara

Amblyseiulella amanoi Ehara , in Ehara et al., 1994: 137; Chant & McMurtry, 2003a: 215; 2007: 49; Moraes et al., 2004b: 10. Amblyseius (Asperoseius) heveae .— Ehara & Bhandhufalck, 1977: 76; Liang & Ke, 1982: 351 (misidentifications, according to Yoshida-Shaul & Chant, 1995: 15).

Specimens examined. One female, on Gossypium sp., at Nan Province, November 1999.

Female

Dorsal shield 340 long and 195 wide; j1 40, j3 78, j4 7, j5 6, j6 13, J5 5, z2 22, z4 37, z5 7, Z1 10, Z4 80, Z5 88, s4 103, S2 43, r3 59, R1 32; distances between St1-St3 70, St2-St2 68, St5-St5 80; ventrianal shield 130 long, 72 wide at level of ZV2; calyx of spermatheca 3 long and 10 in diameter; fixed cheliceral digit 30 long with 10 teeth, movable cheliceral digit 34 long with 3 teeth; Sge I 22, Sge II 24, Sge IV 55, Sti IV 53, St (basitarsus) IV 72, St (telotarsus) IV 47. Chaetotaxy: genu II 2, 2/0-2/0, 1; genu III 1, 2/1-2/0, 1.

Previous records. China ( Liang & Ke, 1982), Japan, South Korea and Thailand (Province of Chiang Rai, Ehara & Bhandhufalck, 1977).

Remarks. Measurements of the specimen examined are similar to those reported by Ehara & Bhandhufalck (1977) for specimens fromThailand and Liang & Ke (1982) for specimens from southern China, previously identified as Amblyseiulella heveae (Oudemans) . Examining the holotype, Yoshida-Shaul & Chant (1995) concluded those reports to correspond to a different species. It is considered in this paper that the specimen examined and those previous records correspond to A. amanoi . However, the specimen examined differs from the original description by having ten teeth on the fixed and three on the movable cheliceral digits, instead of 6–7 and two teeth, respectively. This species is very similar to several others that can be distinguished from A. amanoi as follows: Amblyseiulella prunii ( Liang & Ke, 1982) —macrosetae of tibia, basitarsus and telotarsus of leg IV about 30% shorter and movable cheliceral digit with two teeth; Amblyseiulella nucifera ( Gupta, 1979) —macrosetae of tibia, basitarsus and telotarsus of leg IV about 30% shorter; Amblyseiulella omei ( Wu & Li, 1984) — R1 smooth (serrate in A. amanoi ) and z4 about 2.6 as long as z2; Amblyseiulella xizangensis (Wu in Wu et al., 1997a) fixed cheliceral digit with three teeth.
