Typhlodromus (Anthoseius) kenyae Zannou, Moraes & Oliveira , n. sp.

( Fig. 27 )

Diagnosis. This species is characterized by having all dorsal setae serrate, except J5, smooth; Seta z2 closer to j3 than to z3; ventrianal shield pentagonal; seta JV5 serrate and knobbed; calyx of spermatheca bell-shaped; atrium small, incorporated in calyx.

FEMALE. (2 specimens measured). Idiosomal setal pattern: 12A:8A/JV:ZV.

Dorsum. Dorsal shield, 282 (277–288) long and 156 (152–160) wide, reticulate. Apparently with 5 pairs of solenostomes. Setae j1 17 (14–19), j3 22 (21–24), j4 17 (16–18), j5 18, j6 23 (22–24), J2 26 (24–27), J5 9 (8–10), z2 19, z3 24, z4 25 (24–26), z5 20 (19–21), Z4 34 (32–37), Z5 50 (46–53), s4 26 (26–27), s6 27 (26– 29), S2 32 (30–34), S4 30 (27–32), S5 20 (18–22), r3 23 (21–26), R1 22 (21–24). Setae serrate and sharptipped, except J5, smooth; and Z5, knobbed .

Peritreme. Extending to level of j1.

Venter. Sternal shield too weakly sclerotized to be illustrated and described; distances between ST1–ST3 53, ST2–ST2 51. Genital shield smooth; distance between ST5–ST5 50 (48–51). Ventrianal shield smooth, pentagonal, with anterior margin straight, 94 long, 67 (59–75) wide at level of ZV2, 60 (56–64) wide at level of anus, with 4 pairs of pre-anal setae (JV3 present); elliptical pre-anal pores slightly posterior and mesad of JV2. With 2 pairs of metapodal shields. Caudoventral setae smooth; except JV5, serrate and knobbed.

Chelicera. Movable digit 24 long, with 2 teeth; fixed digit 22 long, apparently with 3 to 4 teeth.

Spermatheca. Calyx bell-shaped, 13 (11–14) long, 10 in diameter; atrium small, incorporated in calyx.

Legs. Macroseta knobbed: Sge IV 6, Sti IV 13, St IV 16. Leg IV with 4 and 3 knobbed setae on genu and tibia. Chaetotaxy: genu II: 2-2/1, 2/0- 1; genu III: 1-2/1, 2/0-1.

Locality and type material. Holotype and 2 paratype females from Acacia brevispica , 25 km S. Malindi, Coastal Province , Kenya, 1-XII-1989, J.S. Yaninek, deposited at ESALQ-USP; 2 paratype females from Mangifera indica , 5 km N. Mtwapa, Coastal Province, Kenya, 30-XI-1989, J.S. Yaninek, deposited at IITAIM.

Etymology. The name kenyae refers to the country where the types of this species were collected.

Remarks. Typhlodromus (A.) combretum , T. (A.) michaeli , T. (A.) coryphus and T. (A.) machaon differ from this new species by having ventrianal shield subquadrate, with lateral margins straight and at most 1.2 times as long as wide instead of pentagonal and at least 1.4 times as long as wide in the new species. Furthermore, T. (A.) combretum , T. (A.) coryphus, T. (A.) machaon have seta JV5 sharp-tipped, T. (A.) michaeli has relatively longer dorsal setae and z2 inserted mid-way between z3 and j3, and T. (A.) machaon has calyx a long tube flaring towards vesicle.
