(Fig. 10)
DIAGNOSIS—Seta Z1 present; setae Z5 much longer than distance between their bases; ratios s4:Z1 = 13.5, s4:S2 = 13.5. Ventrianal shield pentagonal. Fixed cheliceral digit with 10 teeth. Genu of leg I with a macroseta. Spermatheca with calyx swollen basally, bladder-like, then narrowing and flaring distally; atrium nodular, small.
FEMALE—(Specimen measured—Zambia: 1). Idiosomal setal pattern 10A:9B/JV-3:ZV.
Dorsum (Fig. 10 A)—Dorsal shield smooth, 304 long and 184 wide. Setae j1 28, j3 36, j4 5, j5 5, j6 5, J2 5, J5 5, z2 8, z4 8, z5 5, Z1 6, Z4 101, Z5 218, s4 81, S2 6, S4 6, S5 6, r3 12, R1 5. Setae smooth, except Z4 and Z5, lightly serrate.
Peritreme—Extending forward to level of j1.
Venter (Fig. 10 B)—Sternal shield mostly smooth, with few lateral striae; posterior margin wavy; distances between, St1-St3 56, St2-St2 62. Genital shield smooth; distance between St5-St5 59. Ventrianal shield smooth, pentagonal, anterior margin straight, 97 long, 84 wide at level of Zv2 and 72 wide at level of anus; preanal pores elliptical and in line with Jv2. Two pairs of metapodal shields.
Chelicera—Movable digit 30 long, with apparently 3 teeth; fixed digit 23 long, apparently with 10 teeth and a pilus dentilis.
Spermatheca (Fig. 10 C)—Calyx swollen basally, bladder-like, then narrowing and flaring distally, 20 long; atrium nodular, small.
Legs—Sharp-tipped macrosetae: Sge I 36, Sge II 30, Sge III 42, Sti III 31, Sge IV 105, Sti IV 66, St IV 67); presence of a prominent erect seta at base of tarsus I.
MALE—(Specimen measured—Zambia: 1)
Dorsum—Dorsal shield pattern as in female, 261 long and 190 wide. Setae j1 23, j3 36, j4 3, j5 3, j6 3, J2 5, J5 5, z2 6, z4 5, z5 3, Z1 5, Z4 101, Z5 203, s4 81, S2 5, S4 5, S5 5, r3 8, R1 5. Setae smooth, except Z4 and Z5, lightly serrate.
Peritreme—Extending forward to level between j1 and j3.
Venter—(Fig. 10 F)—Ventrianal shield subtriangular, with transverse striae anteriorly to Jv2, 109 long, 147 wide at the anterior corners, with 4 pairs of lyrifissures (1 anterior to Jv1, 2 lateral and almost in line or slightly posterior to Jv1 and 1 lateral and slightly posterior to Zv2); preanal pores elliptical and in line with Jv2.
Spermatodactyl (Fig. 10 E)—L-shaped; shaft 16 long.
Legs—Sharp-tipped macrosetae: Sge I 34, Sge II 30, Sge III 37, Sti III 31, Sge IV 81, Sti IV 55 and St IV 62.
LOCALITY AND TYPE MATERIAL—Holotype female and 1 allotype male from Psidium guajava, Lumangwe Falls, Zambia, 14-VI-1990, J.S. Yaninek deposited at ESALQ-USP.
ETYMOLOGY—The epithet lumangweensis refers to the location where the types of this species were collected.
REMARKS – Amblyseius chanioticus Papadoulis, 1997, A. monacus Wainstein, 1975 and A. pamperisi Papadoulis, 1997 differ from the new species by having z2 and z4 at least twice as long; in addition A. chanioticus has ventrianal shield vase-shaped, with 2 pairs of preanal setae; A. monacus has s4, Z4 and Z 5 25–40 % shorter and A. pamperisi has Z5 ca. 30% shorter than in the new species. Amblyseius sculpticollis Denmark & Evans (in Denmark et al. 1999), A. supercaudatus Karg, 1994 and A. longisaccatus Wu, Lan & Liu, 1995 differ from the new species by having Z4 and Z5 45–70% longer. Furthermore, the first two species have the atrium of the spermatheca undifferentiated and the last has fixed cheliceral digit with more than 15 minute teeth. Amblyseius incognitus Schuster, 1966 also differs from the new species by having atrium of spermatheca undifferentiated; fixed cheliceral digit with 2 large subapical teeth and 18–20 minute teeth; and Sge IV as long as St IV, each ca. 20% longer than Sti IV.
