Eye sizes and interdistances:AME 0.12,ALE 0.25, PME 0.44, PLE 0.25, AME–AME 0.18, AME–ALE 0.63, PME–PME 0.18, PME–PLE 0.53, AME–PME 0.14. Palp measurements: 5.1 (2.46, 0.53, 1.11, -, 1.00). Leg measurements: I: 46.77 (12.78, 1.65, 13.49, 14.58, 4.27). II: 33.75 (11.06, 1.63, 9.11, 8.18, 3.77). III: 23 (8.33, 1.36, 6.49, 5.56, 1.26). IV: 22.78 (8.20, 1.36, 6.66, 5.52, 1.04).

Coloration. Clypeus brown. Areas around AME, ALE and PME covered with white plumose setae. Chelicerae anteriorly yellow with tiny dark brown spots and stripes, lateral sides dark brown, 1 pro-, 1 retrolateral teeth and number of both pro- and retrolateral denticles. Carapace dark brown with yellow white median band and yellowish lateral stripes. Sternum black, with longitudinal light-yellow stripe. Labium completely brown. Endites and coxae dark gray.

Palpal femur yellowish proximally and brown distally; patella brown; tibia and cymbium dark brown. Legs coloration. Coxae dark gray; femora I dark brown, II–IV brown; patellae I dark brown, II–IV brown; tibiae brown; metatarsi I–III brown, IV yellowish; tarsi I, III brown, II, IV yellowish.

Abdomen brown dorsally, with a longitudinal dark stripe and series of indistinct slash stripes posteriorly. Sides of abdomen dark gray with brown longitudinal stripes. Ventral part of abdomen yellowish medially, dark gray anteriorly and posteriorly, spinnerets black.

Male palp as shown in Figs 27–29 , 31 . Femur 2.5 times longer than cymbium. Patella 1.8 times shorter than tibia. Tibia 2.4 times shorter than femur. Cymbium of almost same length as tibia. Cymbial length/width ratio 1.4. Tegulum (Te) wider than the diameter of embolic coil. Sperm duct (SD) clearly visible in pro- and retrolateral view. Median apophysis (MA) small, its basal lobe poorly visible; distal lobe thin, hook-like in prolateral view. Embolus (Em) originates at 6 o’clock, coiling ca 1260° around MA and ending at 12 o’clock. Tip of embolus slightly curved and widened, embolic middle apophysis large, semi-transparent (invisible without dissection of embolus).

Notes. This record of A. liukuensis from Borneo is the easternmost and southmost in its entire range. The nearest known location, in China, is nearly 1600 km to the northwest ( Fig. 51 ). The species belongs to liukuensis -group.

Distribution. India (Tamil Nadu), China (Guangxi, Hainan, Yunnan), Malaysia (Borneo; new record) ( Fig. 53 ).
