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

( Fig. 21 )

Diagnosis. Characterized by having dorsal shield mostly smooth, with lateral and sparse dorsocentral striae; dorsal setae smooth and knobbed, except Z4 and Z5, serrate, and j1, j4–j6, J5 and z5 sharp-tipped; ventrianal shield mostly smooth, with some reticulations around anus; setae JV5 smooth and knobbed; calyx of spermatheca tubular.

FEMALE. (1 specimen measured). Idiosomal setal pattern: 12A:8A/JV: ZV.

Dorsum. Dorsal shield, 272 long and 150 wide; mostly smooth, with lateral and sparse dorsocentral striae. With 5 pairs of solenostomes. Setae j1 13, j3 16, j4 16, j5 14, j6 19, J2 19, J5 10, z2 14, z3 16, z4 18, z5 16, Z4 26, Z5 38, s4 19, s6 19, S2 22, S4 22, S5 19, r3 16, R1 16. Setae j1, j4, j5, j6, Z4 and Z5 smooth and knobbed, except for Z4 and Z5, serrate; j1, j4-j6, J5 and z5, sharp-tipped .

Peritreme. Extending to level of j1.

Venter. Sternal shield too lightly sclerotized to be illustrated; distances between ST1-ST3 58, ST2-ST2 53. Genital shield smooth; distance between ST5-ST5 51. Ventrianal shield mostly smooth, with some reticulations around anus, pentagonal, with anterior margin slightly concave, 96 long, 80 wide at level of ZV2, 74 wide at level of anus, with 4 pairs of pre-anal setae (JV3 present); round pre-anal pores posteromesad of JV2. With 2 pairs of metapodal shields. Caudoventral setae smooth and sharp-tipped except for JV5, knobbed.

Chelicera. Position renders measurement of digits and count of teeth impossible.

Spermatheca. Calyx tubular, 19 long; atrium small, incorporated in calyx.

Legs. Macrosetae knobbed: Sg IV 11; Sti IV 13, St IV 21. Tibia IV with 2 knobbed setae in addition to the macroseta. Chaetotaxy: genu II: 2-2/0, 2/0- 1; genu III: 1-2/1, 2/0-1.

Locality and type material. Holotype female from unknown plant, Cape Coast , Ghana, 12-XI-1989, J.S. Yaninek, deposited at ESALQ-USP.

Etymology. The name ghanaensis refers to the country where the holotype of this species was found ( Ghana).

Remarks. Typhlodromus (A.) cephalochaitosus differs from this species by having all the dorsal setae knobbed, except j1 and J5, sharp-tipped, and by lacking z3. Typhlodromus (A.) hartlandrowei Evans and Typhlodromus (A.) transvaalensis (Nesbitt) differ from the new species by having most of dorsal setae serrate and much longer as well as by lacking seta JV3.
