Ventrianal shield pentagonal, 111(108) long, 89 (84) wide at level of ZV2and 83(82) wide at level of anal opening, with four pairs of pre-anal setae and two rounded solenostomes (gv3) posteromedially to setae JV2. Setae JV5 28 (28) long, smooth, stout and slightly knobbed distally. Two pairs of inguinal sigilla with primary one rather broad and elongate oval, 21(22) and secondary one smaller and slender, 12(11). Spermatheca (Figure 3 (a)) – Calyx saccular 16 long with posterior third thick-walled; atrium nodular attached to the calyx without neck. Chelicerae (Figure 3 (b)) – Fixed chela 27(24) long with 5 teeth and a pilus dentilis. Movable chela 24 (25) long with 3 teeth. Legs (Figure 3 (c-d)) – Chaetotaxy of genu II 2–2/0, 2/0-1, genu III 1–2/1, 2/0 − 1, with Sge III stout and blunt distally, 17(16) long. Leg IV with Sge IV knobbed, 16(14) long, Sti IV knobbed, 20(18) long and StIV, knobbed and 26(26) long. Male (Figure 4 (a-c)) Dorsum (Figure 4 (a)). Dorsal shield 246–279 long and 170–192 wide, broadly oval and reticulated except for centre of prodorsum. All dorsal setae short, smooth, some blunt distally and stout except for setae Z4 and Z5 which are longer, serrate and latter knobbed distally. Sigilla medially on prodorsum. Five pairs of solenostomes (gd2, gd4, gd6, gd8 and gd9) present. Setae r3 and R1 on dorsal shield. Lengths of setae: j1 13–17, j3 15–20, j4 12, j5 11–14, j6 12–15, J2 14–17, J5 10–11, z2 13–15, z3 12–16, z4 12–17, z5 12–14, Z4 23–24, Z5 38–44, s4 14 –17, s6 15 –20, S2 16 –20, S4 18 –20, S5 11 –13, r3 13–18 and R1 13–17. Peritreme reach anterior to setae j1. Venter (Figure 4 (b)) – Sternogenital shield, 113–133 long and 70–83 wide, with 5 pairs of setae, two pairs of pores and genital opening on anterior margin. Ventrianal shield triangular, 95–110 long and 137–160 wide, fused with peritremal shields and with four pairs of pre-anal setae and two pre-anal pores. Setae JV5 (15–17) flanking ventrianal shield and is smooth and pointed. Spermatodactyl (Figure 4 (c)) – Straight, 19–21 long, forked distally into a knobbed process and a short blunt process. Knobbed process with curved claw-like structure at base of knob. Legs – Same as for female. Etymology – This species is named after the second author’s daughter, Uhone meaning ‘arrived’ in the Venda language one of 11 languages in South Africa. Remarks – This new species was compared with all 320 Typhlodromus (Anthoseius) spp in the Phytoseiidae Database (Demite et al. 2020) and 8 species not in the database (Chatti et al. 2017; Döker et al. 2017; Ferragut and Navia 2017; Fang et al. 2018; Karmakar and Bhowmik 2018; Ferragut and Baumann 2019) and differs from them all but is closely related to T.(A.) haramotoi Prasad (1968) in the shape of the dorsal setae being stout with setae S5 very short, Z4 shorter than distance to setae S5 and Z5 long serrate and knobbed distally, leg IV with 3 knobbed macrosetae and setae JV5 knobbed. However, it differs from T. (A.) haramotoi in that setae Z4 are serrate, genu II has 6 setae and in the shape of the spermatheca (Schicha and McMurtry 1986). It is also closely related to T. (A.) gressitti McMurtry and de Moraes (1985) in having all dorsal setae smooth except for setae Z5 which are serrate and knobbed, 3 knobbed setae on leg IV and appearance of spermatheca. It differs from T. (A.) gressitti in that all dorsal setae (except Z5) are slender but stout in new species, setae JV5 acute but knobbed in new species, pre-anal pores are situated behind setae JV2 but posteromedially to JV 2 in the new species and peritreme are slightly bent backwards between setae j1 but not bent in new species. The macrosetae on leg IV are also longer than that of T. (A.) gressitti with the one on genu IV twice as long as that of the latter.
