Description. Male. Body medium ( Fig. 8 View FIGURES 7 – 8 ), occiput somewhat convex, frontal rostrum bluntly round, slightly wider than antennal scape, antennal scape shield-shaped. Lateral ocelli, round, located at the base of side rostrum; median ocellus like half moon, located at antennal fossa. Apical joint of maxillary palpi depressed, arc-shaped, slightly equal with the third joint; apical joint of labial palpi equal with second joint, depressed and flat, truncate. Eyes medium, oval, ventral margin with a lot of fine transverse striation, inside of the bottom corner slightly protruding.
Pronotum obviously transverse, flat, with more pubescent. Anterior margin concave, posterior margin straight, about 1.7 times as long as wide. Metanotal gland developed, as in Fig. 14 View FIGURES 9 – 14 ; central area of anterior margin and posterior margin concave; metanotal gland central area with few pubescent. Tegmina short, extending to base of 5th the abdominal tergite, present with 6 oblique veins, and without mirror, apical area with irregular crossvenation; with 6 longitudinal veins in lateral field; apical portions armed with reticulated veins. Fore tibiae with two tympana, oval, internal larger than external; hind tibiae armed with small spines on the basal half portion and with 4 long spines respectively on both sides at the apical half portion.
Supra-anal plate short and trapezoid ( Fig. 11 View FIGURES 9 – 14 ), about 3.5 times as long as wide. Posterior margin straight, with bristle. Genitalia ( Figs. 18–21 View FIGURES 18 – 21 ): Epiphallus equipped with a pair of thick median lobes; lateral lobes wide and armed with two acute apex, axe-shaped; ectoparamere longer than lateral lobes.
Female. Unknown.

Distribution. China (Hainan).
Diagnosis. This new species is related to Duolandrevus (Eulandrevus) dendrophilus ( Gorochov, 1988) , but can be distinguished on the shape of the lateral lobes of the epiphallus, the lateral lobe of the epiphallus bifurcate; ectoparamere longer than lateral lobes.
Etymology. This new specific name is derived from Greek axin, referring the lateral lobe of epiphallus with an axe-shaped apex
