Etymology.

The species name is a boy’s name from Vietnam; noun (name) in genitive case.

Diagnosis.

The new species resembles A. bidentatus Mi & Li, 2022 in appearance, but can be distinguished from it in having: 1) the copulatory openings situated on the anterior surface of the epigyne (Fig. 4B, C View Figure 4 ) vs at the lateral ends of the scape groove ( Mi and Li 2022: fig. 3A, B); 2) the scape not grooved (Fig. 4A-D View Figure 4 ) vs grooved ( Mi and Li 2022: fig. 3A, B); 3) the tibia of the male palp with three heavily sclerotized, denticulate protuberances (see arrows in Fig. 5A, E View Figure 5 ) vs with two protuberances ( Mi and Li 2022: fig. 4A, B, E); 4) the median apophysis curved about 90° (Fig. 5A-D View Figure 5 ) vs curved about 20° ( Mi and Li 2022: fig. 4A); and 5) the sternum paler in the middle (Fig. 4F View Figure 4 ) vs unicolor ( Mi and Li 2022: fig. 3H).

Chelicerae yellowish brown, with five promarginal and three retromarginal teeth. Endites and labium yellowish brown, paler distally. Sternum dark brown with wide yellow band. Legs brown with grayish-brown annuli; tibia I with 13 macrosetae; tibia II with 10 macrosetae; tibia III with six macrosetae; tibia IV with nine macrosetae. Abdomen elliptical, ~1.3 × longer than wide, covered with dark setae; dorsum yellow with grayish brown patches; venter yellow with irregular grayish brown markings. Spinnerets yellowish brown.

Palp (Fig. 5 View Figure 5 ): with two patellar bristles; tibia ~3.0 × wider than long in retrolateral view, with three heavily sclerotized, denticulate protuberances and a short ventral projection; paracymbium finger-like; tegulum smoothly rounded in retrolateral view; median apophysis longer than wide, with pointed tip bent about 90°, distal end pointed toward the tip of cymbium in prolateral view; embolus thread-like; conductor curled, covering most of embolus in prolateral view; terminal apophysis about as long as bulb diameter, bifurcated distally.
