( Fig. 56 )

Diagnosis. Characterized by having dorsal shield strongly reticulate; most “lateral” setae and Z4 serrate, dorsocentral (j4–J5) and marginal setae (r3 and R1) smooth, seta Z4 shorter than the distance between its base and that of Z5, j6 about half as long as the distance between it base and that of J2, and the latter about half as long as the distance between its base and that of Z4; sternal shield with median longitudinal striae; genital shield with longitudinal striae laterally; fixed cheliceral digit with 7 teeth.

FEMALE. (2 specimens measured). Idiosomal setal pattern: 12A:7A/JV:ZV.

Dorsum. Dorsal shield 308 (304–312) long and 169 (168–170) wide, strongly reticulate. With 5 pairs of solenostomes. Setae j1 20 (19–21), j3 30 (29–32), j4 17 (16–18), j5 20 (19–21), j6 25 (24–26), J2 38 (37–38), J5 8, z2 17 (16–18), z3 31 (30–32), z4 26 (24–27), z5 20 (19–21), Z4 40 (38–42), Z5 57 (56–58), s4 38 (37– 38), s6 46 (45–48), S2 48, S4 51 (50–53), r3 26 (24–27), R1 21 (19–22). Setae j1, j4, j5, j6, J2, J5, z2, z4, z5, r3 and R1 smooth, other setae slightly to distinctly serrate .

Peritreme. Extending to level between j1 and j3.

Venter. Sternal shield with median longitudinal striae; posterior margin straight; distances between ST1– ST3 56, ST2–ST2 54. Genital shield with longitudinal striae laterally; distance between ST5–ST5 56. Ventrianal shield striate, pentagonal, with anterior margin straight, 111 (110–112) long, 82 (80–83) wide at level of ZV2, 67 (64–70) wide at level of anus; round pre-anal pores posterior to and almost vertically aligned with JV2. Caudoventral setae smooth and sharp-tipped, except, JV5, serrate.

Chelicera. Movable digit 26 (25–26) long, with 2 teeth; fixed digit 23 (22–24) long, with 7 teeth.

Spermatheca. Calyx saccular, 21 long, and 11 (10–11) in diameter at mid-length; atrium small and nodular.

Legs. Macrosetae sharp-tipped: Sge IV 21, Sti IV 26, St IV 50; macrosetae are present on genu and tibia of leg IV in one of the two specimens examined. Chaetotaxy: genu II: 2-2/0, 2/0- 1; genu III: 1-2/1, 2/0-1.

Locality and type material. Holotype female and one paratype female from Ipomoea sp. , 74 km N Kibuye, Prefecture de Gisenyi , Rwanda, 7-XII-1989, J.S. Yaninek, deposited at ESALQ-USP.

Etymology. The name neomagdalenae refers to the similarity between this species and T. (T) magdalenae .

Remarks. Typhlodromus (T.) magdalenae differs from this new species by having seta Z4 longer than the distance between its base and that of Z5; j6 about as long as the distance between it base and that of J2, and the latter at least 0.9 times as long as the distance between its base and that of Z4; sternal shield mostly smooth, with few lateral striae; genital shield smooth.
