Trigonobothrys Simon, 1889 = Phycosoma O. Pickard-Cambridge, 1880 (Fitzgerald & Sirvid, 2003: 28, with erroneous priority, contra Levi & Levi, 1962: 26)

N.B.: removed from the synonymy of Euryopis Menge, 1868 by Fitzgerald & Sirvid, 2003: 28 (contra Levi & Levi, 1962: 26), considered a junior synonym of Trigonobothrys Simon, 1889b: 230 [urn:lsid:nmbe.ch:spidergen:05722] (type T. excisus Simon, 1889) by Fitzgerald & Sirvid, 2003: 28, but actually a senior synonym of that name; Trigonobothrys was removed from the synonymy of Dipoena Thorell, 1869 by Yoshida, 2002a: 14, contra Levi & Levi, 1962: 25-32 and was considered by Yoshida, 2002a: 14 to include "the species of the D. lineatipes group designated by Levi (1953)" but only taxa explicitly transferred by him are listed here, until a wider, worldwide sample of taxa can be studied; Trigonobothrys considered part of Lasaeola Simon, 1881 by Wunderlich, 2008b: 283.
