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

( Fig. 4 )

Diagnosis. This species is distinct by having dorsal shield strongly areolate; dorsal setae slightly thickened; setae Z4, Z5 and S4 lanceolate and strongly serrate, Z5 slightly knobbed; caudoventral seta JV5 smooth and knobbed; calyx of spermatheca saccular; macroseta present only on basitarsus of leg IV.

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

Dorsum. Dorsal shield, 317 long and 179 wide, strongly areolate. Setae j1 18, j3 26, j4 16, j5 16, j6 19, J2 24, J5 10, z2 18, z3 19, z4 22, z5 18, Z4 32, Z5 42, s4 22, s6 24, S2 27, S4 32, S5 21, r3 16, R1 19. Setae smooth, slightly thickened and sharp-tipped, except Z4, Z5 and S4, lanceolate and strongly serrate, and Z5, slightly knobbed .

Peritreme. Extending to level of j1.

Venter. Sternal shield smooth, posterior part of lateral margins and posterior margin indistinct; ST1 and ST2 inserted on well sclerotized portion of shield; ST3 inserted on unsclerotized cuticle; distances between ST1-ST3 56, ST2-ST2 51. Genital shield smooth; distance between ST5-ST5 61. Ventrianal shield smooth, pentagonal, with anterior margin almost straight, 107 long, 80 wide at level of ZV2, 72 wide at level of anus, with 4 pairs of pre-anal setae; elliptical pre-anal pores posteromesad of JV2. With 2 pairs of metapodal shields. Caudoventral setae smooth and sharp-tipped, except JV5, knobbed.

Chelicera. Position renders it impossible to measure the digits and counting the numbers of the teeth.

Spermatheca. Calyx saccular, 17 long; atrium bifurcate.

Legs. Macroseta knobbed: St IV 19. Genu and tibia IV with 3 and 2 knobbed setae, respectively. Chaetotaxy: genu II: 2-2/0, 2/0- 1; genu III: 1-2/1, 2/0-1.

Locality and type material. Holotype female from Chromolaena odorata , 37 km E. Bertoua, Cameroon, 3-II-1991, A. Onzo, deposited at ESALQ-USP.

Etymology. The name asperosetosus refers to the shape of setae Z4, Z5 and S4 of this species.

Remarks. Typhlodromus (A.) matthyssei Ueckermann & Loots and T. (A.) terrulentis Van der Merwe differ from this new species by having S5 serrate. Furthermore, the former has seta S4 setiform and smooth, calyx of spermatheca slender near atrium oppose to buldge near atrium in the new speies, whereas the latter has Z4 knobbed. In the new species and T (A.) terrulentis setae Z4 are more than half the length to S5, whereas in T. (A.) matthyssei it is shorter than half the distance to S5. The shapes of the spermathecae of the three species also differ clearly.
