( MPEG 35019).   Revised diagnosis.  A. draconicaudatusis similar to  A. shenlong  sp. nov.by having an elongate and stout projection on the retrolateral border of the embolic disc that extends towards the retrolateral tegulum border and bears several branches ( Figs 21D, 26A, 26C, 27A); also, by having the RvTA pointing ventrally, with projections on its border ( Figs 21F, 22B, 26G). However, the male of  A. draconicaudatuscan be distinguished by having the RvTA with a single serrated projection, and a RTA reduced to spikes ( Figs 26G, 27B–D), whereas in  A. shenlong  sp. nov.the RvTA has four projections (three with acute tip and one with serrated tip), and the RTA serrated tip reaches the same height of the RvTA tip along palp axis ( Figs 21F, 22B, 26H). The female of  A. shenlong  sp. nov.is unknown, but among the currently known females of  Amphidraus,  A. draconicaudatus  sp. nov.is most similar to those of  A. draconitupan  sp. nov., both with spermathecae kidney-shaped, with glands near copulatory openings and with a narrow dorsal pocket placed posteriorly on epigynal plate ( Figs 24D, 25D, 27E). However, the female of  A. draconicaudatus  sp. nov.can be distinguished from that of  A. draconitupan  sp. nov.by having longer copulatory ducts connected to the inner posterior border of spermathecae (see Salgado & Ruiz 2017: fig. 24F), whereas they connect to the outer border of the spermathecae in  A. draconitupan( Fig. 25D).   Description.See Salgado & Ruiz (2017).  Variation.Among the males examined, we observed the following variation in palpal structures ( Figs 26A–D, 26G): the superior border of the branched projection of embolic disc can be smooth ( Figs 26A–B) or occupied by large serial spikes (similar to a comb) ( Figs 26C–D). We decided to refrain from describing this variation as a new species and all these forms are considered conspecific. Also, the number and shape of branches on the RvTA is variable ( Fig. 26G; see Salgado & Ruiz 2017: figs 23B, 24B, 24D).  Note.  Amphidraus draconicaudatus, A. shenlong  sp. nov.and  A. draconitupan  sp. nov.clearly compose a particular group within the genus. The males in this group have one stout projection that emerges from the retrolateral border of the embolic disc and extends towards to retrolateral border of tegulum ( Figs 22A, 25A, 26A, 27A). Moreover, males also have pockets on outer faces of chelicerae ( Figs 28A–C, 29A–B), of unknown use.   Distribution.Known only from the state of Tocantins( Brazil) ( Fig. 30). 2013952931 [525,771,1256,1281] 2016-05-11 MPEG A.
