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

( Fig. 37 )

Diagnosis. This species is characterized by having anterior part of proscutum narrow; most of the dorsal setae knobbed, longer than distances between their bases and the bases of consecutive setae, seta r3 and R1on integument; sternal, genital and ventrianal shields reticulate; sternal shield with 2 pairs of setae (ST3 on separate shields); distal two-thirds of calyx of spermatheca bell-shaped and rest slender.

FEMALE. (2 specimens measured). Idiosomal setal pattern 12A:8A/JV-3:ZV.

Dorsum. Dorsal shield 291 (290–291) long and 163 wide, reticulate. With 5 pairs of solenostomes, not all indicated in fig 37. Setae j1 24, j3 45 (45–46), j4 40 (39–42), j5 47 (44–50), j6 55 (53–58), J2 59 (58–61), J5 9 (8–10), z2 28 (27–29), z3 42, z4 57 (56–58), z5 35 (31–38), Z4 68 (67–68), Z5 68 (67–68), s4 62 (61–62), s6 73 (72–74), S2 76 (76–77), S4 75, S5 29 (29–30), r3 36 (34–38), R1 64. Most setae serrate and knobbed; setae j1, z2, z5, S5 and r3 knobbed, sharp-tipped, and seta J5 smooth and sharp-tipped. Most setae longer than distance between their bases and the bases of consecutive setae.

Peritreme. Extending to level of j3.

Venter. Sternal shield reticulate, with 2 pairs of setae (ST3 on separate shields); posterior margin with a quadri-dentate median projection; distances between ST1–ST3 50, ST2–ST2 49. Genital shield reticulate; distance between ST5–ST5 53. Ventrianal shield reticulate, subtriangular, with anterior margin slightly convex, 102 (96–107) long, 91 (90–91) wide at level of ZV2, with 3 pairs of pre-anal setae (seta JV3 absent); round pre-anal pores posteromesad of JV2. With 2 pairs of metapodal shields. Caudoventral setae smooth and sharptipped, except JV5, serrate and knobbed.

Chelicera. Movable digit 26 long, with 1 tooth; fixed digit 26 long, with 2 teeth.

Spermatheca. Sixty percent of calyx adjacent to vesicle bell-shaped rest slender, 18 (10–27) long; atrium nodular.

Legs. Macrosetae knobbed: Sge IV 29, Sti IV 25 (22–27), St IV 43. Chaetotaxy: genu II: 2-2/0, 2/0- 1; genu III: 1-2/1, 2/0-1.

Locality and type material. Holotype female from Elaeis guineensis , 27 km SW Ngoulemakong, Cameroon, 6-II-1991, L. Louis; 1 paratype female from E. guineensis , 12 km W Angale, Cameroon, 7-II-1991, L. Louis; both types deposited at ESALQ-USP.

Etymology. The name neohartlandrowei refers to the similarity between this species and T. (A.) hartlandrowei .

Remarks. Typhlodromus (A.) hartlandrowei and T. (A.) transvaalensis ( Nesbitt, 1951) differ from this new species by having the anterior part of the proscutum broad, and sternal and genital shields smooth. In addition, the former species has r3 on dorsal shield and macrosetae present on genu and tibia of leg III, while the latter has most of the dorsal setae shorter than distance between their bases and the bases of setae next behind, ventrianal shield pentagonal and striate, and 8 setae on genu of leg II.
