Rhene Thorell, 1869

Rhene Thorell, 1869: 37 (replacement name for Rhanis C.L. Koch, 1846, preoccupied; type species: Rhanis flavigera C.L. Koch, 1846).

Zeuxippus Thorell, 1891: 109 (type species: Zeuxippus histrio Thorell, 1891, examined based on illustrations and images of the type species kept at the Zoological Museum, Copenhagen, http://www.daim.snm.ku.dk/The-digitized-type-collection). syn. n.

Justification of synonymy. The morphology and copulatory organs of Zeuxippus Thorell, 1891 appear similar to that of Rhene Thorell, 1869 . Based on a detailed comparison of the illustrations of the generotype, Zeuxippus histrio Thorell, 1891 (Prószyński, 1984), it is evident that it has all the diagnostic features of Rhene as illustrated for Rhene flavigera (C.L. Koch, 1846) . The palp with short, curved embolus accompanied by a hook-shaped terminal apophysis; simple pointed RTA; bag-like tegulum and sperm duct of the palp with retromarginal loop are diagnostic for Rhene . Expect the longer, more obtuse abdomen, characteristic differences in palpal structure are not seen. Therefore, Zeuxippus is considered a junior synonym of Rhene .

The synonymy has resulted in four new combinations: Rhene atellana (Thorell, 1895) comb. n., Rhene histrio (Thorell, 1891) comb. n., Rhene pallida (Thorell, 1895) comb. n., and Rhene yunnanensis (Peng & Xie, 1995) comb. n. .
