( Fig. 36 )

Diagnosis. This species is distinct by having dorsal shield reticulate; dorsal setae smooth and sharp-tipped, except Z4 serrate, sharp-tipped or knobbed, and Z5, serrate and knobbed; Z4 as long as the distance between its base and the base of S4, S5 about half as long as S4; sternal shield with 3 pairs of setae (ST3 on shield), with posterior margin straight; knobbed macrosetae on genu and tibia of leg III and on genu, tibia and basitarsus of leg IV. Furthermore, the spermatodactyl of the male is straight, slightly constricted distally and knobbed.

Venter. Sternal shield smooth, with 3 pairs of setae; posterior margin straight; distances between ST1–ST3 56 (54–56), ST2–ST2 60 (56–61). Genital shield smooth; distance between ST5–ST5 58 (58–59). Ventrianal shield smooth, pentagonal, with anterior margin slightly convex, 104 (99–112) long, 90 (82–99) wide at level of ZV2, 81 (69–88) 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 JV5, knobbed.

Chelicera. Movable digit 22 long, with 3 teeth; fixed digit 22 long, with 5–6 teeth.

Spermatheca. Calyx saccular, 11 (8–13) long; atrium distinct.

MALE. (2 specimens measured)

Dorsum. Dorsal shield pattern and setae as in female, 240 (238–241) long and 150 (1146–154) wide. Setae j1 14 (13–15), j3 17 (16–17), j4 11 (10–12), j5 11, j6 14 (13–14), J2 16, J5 9, z2 12 (11–12), z3 14, z4 15 (14–15), z5 12 (11–12), Z4 21 (20–21), Z5 32 (31–32), s4 17 (16–17), s6 18 (17–18), S2 18, S4 16, S5 12, r3 16, R1 14 (13–14).

Peritreme. Extending to level of j1.

Venter. Ventrianal shield subtriangular, reticulate, free from peritrematal shields, 92 (91–92) long, 138 (136–139) wide at anterior corners; with 4 pairs of pre-anal setae and no distinguishable lyrifissures; round pre-anal pores posteromesad of JV2. Caudoventral setae smooth and sharp-tipped.

Spermatodactyl. Straight, slightly constricted distally, terminating into a knob, shaft 22 long.

Legs. Macroseta sharp-tipped; St IV 18. Chaetotaxy of genua II and III as in female.

Locality and type material. Holotype female, 3 paratype females, allotype male and 1 paratype male from Citrus sp. , Kyankonwa, Uganda, 5-X-1990, J.S. Yaninek, deposited at ESALQ-USP; 1 paratype female from unknown plant, 26 km N Bundibugyo, Uganda, 9-X-1990, J.S. Yaninek, deposited at IITAIM. One paratype female from Persea americana , 11 km W Diang, Cameroon, 4-I-1991, L. Louis, deposited at IITAIM.

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

Remarks. Seta z6 is present in one of the paratype females from Uganda. The presence of seta z6 is a typical characteristic of the tribe Paraseiulini Wainstein. Two of the types from Uganda have Z4 knobbed, while this seta is sharp-tipped in the others. Typhlodromus (A.) ndibu differs from this new species by having calyx of spermatheca funnel-shaped and atrium undifferentiated. Typhlodromus T. (A.) gutierrezi also differs by lacking macrosetae on genu and tibia of leg III. Furthermore, the male of T. (A.) gutierrezi has spermatodactyl slender distally.
