Description. See Bryant (1943).

Note. A. manni and A. mendicus are clearly members of the euophryines by the spiraled embolus and the well developed RSDL, but differ from Amphidraus , which does not have a well developed RSDL, by a simple RTA and an embolic disc poorly developed, with no processes ( Figs 27 A, 27C). These species share great similarity with the species of the Antillattus -clade, composed of Antillattus , Petemathis Prószyński & Deeleman-Reinhold, 2012 and Truncattus , which is restricted to the Caribbean Islands (see Zhang & Maddison 2015). The species of this clade usually have two promarginal teeth (see Zhang & Maddison 2015: figs 58, 65, 66, 73, 75, 88, 94) and a coiled embolus of no more than half a circle (see Zhang & Maddison 2015: figs 50, 57, 64, 72, 80, 87, 93). Among the genera of this clade, A. manni and A. mendicus share more morphological similarities with Truncattus in having the chelicera with one bicuspid retromarginal tooth and with a retrolateral depression on the chelicerae ( Figs 27 B, 27D; see Zhang & Maddison 2012b: fig. 260; Zhang & Maddison 2015: Fig. 94), and the male palp with a large proximal tegular lobe ( Figs 27 A, 27C; see Zhang & Maddison 2012b: figs 240, 249, 259). Based on this evidence, these two species are herein transferred to Truncattus .
