Etymology. The specific name is an adjective taken from the type locality.
Diagnosis. Females of Cheiramiona hogsbackensis sp. nov. can be differentiated by the wide curved shape of the epigynal depression (Fig. 17) and the copulatory tubes that proceed directly posteriorly from the SPER (Fig. 18); males are promptly recognized by the denticles on the inner margin of the RTA (Figs 20–21).
Description. Female (n = 4): TL = 4.13 (3.6–4.5); CL = 1.90 (1.4–2.2); CW = 1.48 (1.1–1.7); OAL = 0.31 (0.25–0.35); OAW = 0.98 (0.70–1.15); CLL = 0.05 (0.05–0.05). Chelicerae: robust with long fangs; PMT:RMT = 4:5 (Fig. 16). Measurements: AME–AME 0.10; AME–ALE 0.20; AME diameter 0.15; PME–PME 0.20; PME– PLE 0.25; PME diameter 0.15; MOQAW 0.40; MOQPW 0.50; CI (CL/CW) 1.29; LL:CL 2.77; STL 1.1; STW 1.0. Leg measurements: I—1.6+0.8+1.4+1.6+0.7 = 6.1; II—1.3+0.7+1.0+1.2+0.6 = 4.8; III—1.1+0.6+0.8+1.0+0.5 = 4.0; IV—1.3+0.8+1.4+1.6+0.6 = 5.7; Palp—0.8+0.4+0.5+0.8 = 2.5. Leg spines: I—0, 0, 0-0- 1 v; II—0, 0, 0-0- 1 v; III—0, 0, 0-0-3 v1 p1r; IV—0, 0, 0-1v-3 v1 p1r. Abdomen: creamy-yellow with pale heart mark and chevron markings posterior of heart mark. Epigynum (Figs 17–18): wider than long, with long, recurved depression in posterior half; copulatory openings situated laterally in depression, near epigastric fold; epigastric fold forming slight lip-like extension; internally, short copulatory ducts with single loop proceed anterially before ending posteriorly in SPER; fertilization tubes enter SPER posterior-laterally.
Male (n = 5): TL = 3.78 (2.9–4.3); CL = 1.86 (1.6–2.1); CW = 1.43 (1.20–1.55); OAL = 0.29 (0.25–0.30); OAW = 0.85 (0.7–0.9); CLL = 0.05 (0.05–0.05). Chelicerae: robust with long fangs; PMT:RMT = 4:4 (Fig. 19). Measurements: AME–AME 0.15; AME–ALE 0.15; AME diameter 0.10; PME–PME 0.20; PME–PLE 0.20; PME diameter 0.10; MOQAW 0.35; MOQPW 0.40; CI (CL/CW) 1.36; LL:CL 2.95; STL 1.0; STW 0.9. Leg measurements: I—1.6+0.8+1.5+1.6+0.7 = 6.2; II—1.2+0.6+1.0+1.1+0.5 = 4.4; III—1.0+0.5+0.7+0.9+0.4 = 3.5; IV—1.5+0.7+1.2+1.3+0.5 = 5.2; Palp—0.8+0.3+0.3+0.8 = 2.2. Leg spines: I—0, 0, 0-0- 1 v; II—0, 0, 0-0- 1 v; III— 0, 0, 0-0-3 v1 p1r; IV—0, 0, 0-1p1r-3 v1 p1r. Abdomen: similar to female. Palp (Figs 20–21): cymbium elongate, longer than patella plus tibia length; tibia with broad RTA with bifid tip, with line of small denticles on inner margin and point near dorsal side; TA slightly sclerotized, curved towards EM at tip; EM short, thick, with narrower pointed apex, apex slightly separated from main body of EM; CON finger-like, distinct but not sclerotized.
Distribution. Only known from the type locality (Fig. 98).
Habitat. Collected at base of grass tussocks and in leaf litter from forests and plantations.
