Re-description Based on female (n =5)

Dorsum ( Fig. 25 ): Colour in life red, Body oval in shape. Length of body from setae v2-h1 213–221; width from sc2-sc2 120–131. Anterior margin of propodosoma deeply notch, depth of notch 18-21, propodosoma with slight lateral lobes anterior marginally; median area of propodosoma framed by longitudinal, broken striae with irregular transverse striae inside this area; lateral area with longitudinal to irregular striae. Opisthosomal integument entirely with rugose pattern; anterior and posterior parts of opisthosoma separated by two plates; dorsal body setae narrow lanceolate serrate to setiform minute serrate, subequal in length, except seta h2 flagellate, whip-like; dorsal opisthosomal pores present in area between setae d3 and e3. Opisthosoma narrower than propodosoma. All dorsal setae short (except h2), not more than 13 in length; setae v2, sc1, and sc2 minute to setiform, third pair of propodosoma setae sc2 longer than first and second pairs v2 and sc1; setae e3 shorter than distance between e3 and f2, h2 flagellate and elongate serrate. Lengths of dorsal setae: v2 5–8, sc1 8–9, sc2 10–13, c1 5–7, c3 5–10, d1 5 5–7, d3 5–6, e1 5 –6, e3 5 –7, f 2 7–8, f 3 7–10), h1 7–8, h2 130–137. Distance between dorsal setae: v2-v2 29–30, sc1-sc1 75–80, c1-c1 34–36, c3-c3 136–142, d1-d1 10–11, d3-d3 115–123, e1- e1 10–13, e3-e3 84–86, f2-f2 73–79, f3-f3 62–63, h2-h2 49–56, h1-h1 18–25, c1-d1 31–36, d1- e1 33–36, c1-c3 49–51, d1-d3 49–52, e1- e3 33–37, c3-d3 25–26, d3- e3 57–64, e3-f2 13–15, f2-f3 15 11–15, h1-h2 10–12.

Venter ( Fig. 26 ): Ventral cuticle with longitudinal striations medially, propodosoma with broken, longitudinal striae.All ventral setae smooth, setae 1a, 4a flagelliform, and elongate, genitoventral plate developed with transverse striae. Setal lengths: 1a 57–57, 1b 25–30, 1c 23–28, 2b 28–33, 2c 27–31, 3a 11–13, 3b 25–29, 4a 73–80, 4b 26–28, ag 15–19, g1 11–15, g2 10–13, ps2 10–12, ps3 10–14. Distance between ventral setae: 1a -1a 20–23, 3a -3a 23–25, 4a-4a 16–21, 1a-3a 51–54, 3a-4a 33–41.

Gnathosoma ( Fig. 27–28 ): Palpi 3-segmented, median segment elongates, bearing one barbed seta d 12–19; distal segment short, with eupathidia ul ′ 3–5, ul ″ 8–12. One pair of subcapitulum seta m 10–13; distance between setae m -m 15–21.

Legs ( Fig. 29–32 ): Legs measurement from trochanter to tarsus; leg I 118–122; leg II 111–113; leg III 101–104 and leg IV 98–103; Number of setae on leg I-IV (from coxa to tarsus, solenidion in parenthesis): coxae 2-2-1-1; trochanters 1-1-1-1; femora 4-4-2-1; genu 2-2-0-0; tibiae 5-5-3-2; tarsus 8(1ω)-8(1ω)-4-4.

Material Examined: Five females ( KSMAAS24 -Ten-Ten-1–5), Cichorium spp. ( Asteraceae ), Jazan, Saudi Arabia, 17. 0291889°N, 43. 138587°E, February 23, 2024, coll. N.A. Elgoni

Distribution: South Africa ( Meyer,1979, 1993) and Saudi Arabia (present study)

Remarks: Our re-description matches with the original description except setae in coxa I which three in original description and two setae in our re-description and variation in the length of the dorsal setae. The species T. emeticae was previously reported from Lannea edulis and Trichilia emetica , while in this study, it was collected from Cichorium spp.
