The male palp of A. liui sp. nov. resembles those of A. heterothecus Zhang, 1985 and A. largosaccatus Zhu, Zhang, Song & Qu, 2006 in having the apex of the embolus pointing toward the tibia, but the new species can be distinguished from the others by its slightly longer embolus and slightly larger conductor (Fig. 4 J – N), and by the less excurved distal edge of the embolus (Fig. 4 K – M). Female genitalia of A. liui sp. nov. resemble those of A. largosaccatus by the similarly sized receptacula with slightly long stalks, but the new species can be distinguished from the latter by the genital atrium, which has larger, paired oval lateral pore patches (Fig. 5), and from A. karschi Dönitz, 1887 by the slightly longer stalks (Fig. 5 A – H) with incrassate bases (Fig. 5 A – Q).
