Amblyseius jamesi Zannou, Moraes & Oliveira , n. sp.

( Fig. 7 )

DIAGNOSIS—Seta Z1 present; setae Z5 much longer than distance between their bases; ratios s4:Z1 = 11.5, s4:S2 = 10.2. Ventrianal shield subpentagonal. Fixed cheliceral digit apparently with 15 teeth. Genu of leg I with a macroseta. Spermatheca with calyx tubular, slightly constricted near vesicle; atrium slightly wider than calyx.

FEMALE—(Specimen measured—Cameroon: 1). Idiosomal setal pattern 10A:9B/JV-3:ZV.

Dorsum ( Fig. 7 A)—Dorsal shield smooth, 351 long and 265 wide. Setae j1 33, j3 37, j4 5, j5 5, j6 5, J2 8, J5 8, z2 5, z4 6, z5 5, Z1 8, Z4 112, Z5 207, s4 92, S2 9, S4 9, S5 6, r3 12, R1 9. Setae smooth.

Peritreme—Extending beyond level of j1.

Venter ( Fig. 7 B)—Sternal shield mostly smooth, with few lateral striae; posterior margin straight; distances between St1-St3 66, St2-St2 75. Genital shield smooth; distance between St5-St5 73. Ventrianal shield with transverse striae anteriorly to Jv2, subpentagonal, slightly constricted at level of preanal pores, anterior margin about straight, 125 long, 81 wide at level of Zv2 and 73 wide at level of anus; preanal pores elliptical, posterior to and slightly mesad to Jv2. Two pairs of metapodal shields.

Chelicera—Position renders illustrations impossible; movable digit 48 long, apparently with 4 teeth; fixed digit 45 long, apparently with 15 teeth and a pilus dentilis.

Spermatheca ( Fig. 7 C)—Calyx tubular, slightly constricted near vesicle, 15 long; atrium slightly wider than calyx.

Legs—Sharp-tipped macrosetae: Sge I 42, Sge II 39, Sge III 45, Sti III 34, Sge IV 94, Sti IV 58, St IV 62); presence of a prominent erect seta at base of tarsus I.

MALE—Unknown.

LOCALITY AND TYPE MATERIAL—Holotype female from Psidium guajava , 27 km SW Ngoulemalong, Cameroon, 06-II-1991, L. Louis, deposited at ESALQ-USP.

ETYMOLOGY—This species is named in honor of the eminent acarologist James A. McMurtry, for his outstanding contribution to the knowledge of the phytoseiid taxonomy.

REMARKS— A. adhatodae and A. hurlbutti Denmark & Muma, 1989 differ from this species by having ventrianal shield smooth and calyx of spermatheca not constricted near vesicle. Amblyseius tamatavensis Blommers, 1974 also differs from the new species by having major duct not distinctly sclerotized and considerably narrower than calyx.
