Diagnosis. This species is distinct by having dorsal shield reticulate; dorsal setae smooth and sharp-tipped, except Z4 and Z5, lanceolate and serrate, and Z5 knobbed; seta Z4 as long as distance between its base and the base of S4; seta S5 about half as long as S4; sternal shield with 3 pairs of setae and with a convex posterior margin; a single and knobbed macroseta on basitarsus of leg IV.

FEMALE. (7 specimens measured). Idiosomal setal pattern: 12A:8A/JV: ZV.

With 2 pairs of metapodal shields. Caudoventral setae smooth and sharptipped, except for JV5 that in some specimens is slightly knobbed.

Yaninek, deposited at ESALQ-USP; 1 paratype female from Euphorbia tirucalli , 16 km NW Bujumbura, Burundi, 11-XII-1989, J.S. Yaninek, deposited at ESALQ-USP; 1 paratype female from Croton floribundus , 84 km NE Bujumbura, Burundi, 12-XII-1989, J.S. Yaninek, deposited at IITAIM; 4 paratype females from Lantana camara , 19 km S Kisumu, Nyanza Province, Kenya, 3-XII-1989, J.S. Yaninek, deposited at IITAIM; 1 paratype female from Cassia sp. , 19 km S Kisumu, Nyanza Province, Kenya, 3-XII-1989, J.S.

Bocharie, deposited at IITAIM; 1 paratype female from Ficus exasperata , 4 km SE Kafu River, Luweero, Uganda, 13-X-1990, J.S. Yaninek, deposited at IITAIM.

Etymology. This species is named in honor of the eminent South African acarologist Jacob Den Heyer.

Remarks. Specimens from Kenya, Sierra-Leone and Uganda have seta JV5 moderately knobbed, whereas this seta is sharp-tipped in specimens from Rwanda and in 2 of specimens from Burundi. Typhlodromus (A.) persianus McMurtry differs from this species by having Z4 as long as the distance between its base and the base of S5, the latter about 0.7 as long as S4, 2 pairs of setae on sternal shield (ST3 on integument) and 4 teeth on the fixed cheliceral digit. Typhlodromus (A.) gutierrezi Blommers differs from the new species by having posterior margin of sternal shield almost straight, calyx of spermatheca half as long as in the new species and by having macrosetae on genu and tibia of leg IV. Typhlodromus (A.) wrenschae Ueckermann & Loots also differs from the new species by having seta Z4 0.7 times as long as the distance between its base and the base of S4 and by having ST3 inserted on integument.
