Male of <i>A. treecko</i> Lin &amp; Li, <b>sp. nov.</b> is similar to <i>A. xiushanensis</i> Song &amp; Zhu, 1991 in having a similarly shaped MA, C, and RTA but can be distinguished by the RTA which narrows toward the terminus and has an obvious bifurcation (<i>vs.</i> terminus extended and bifurcation inconspicuous in <i>A. xiushanensis</i>), and the cymbial apophysis is well developed, triangular (<i>vs.</i> bifurcated in <i>A. xiushanensis</i>). Females are similar to <i>A. xiushanensis</i> by the shape of the epygine, but in <i>A. treecko</i> Lin &amp; Li, <b>sp. nov.</b>, the epygine is anteriorly narrow and flat (<i>vs.</i> blunt in <i>A. xiushanensis</i>) and the CDs in <i>A. treecko</i> Lin &amp; Li, <b>sp. nov.</b> are narrow.
