was withdrawn by Simon (under the name camelinus, Koch) 

 and included in his genus Arrecerus. W. cuspidata, BL, therefore, 

 remains as the type. Thorell, in 1869, selected acuminata, BL, 

 as the type of Walckenaeria ; but this he had no power to do, as 

 the species had been already withdrawn by Simon under Arrecerus 

 (1864). In 1869 Menge formulated the genus Gomicularia for a 

 single species, which from his description and figure is obviously 

 unicornis, Cambr., although by mistake he considered it to be 

 monoceros, Wid. As long as unicornis, Cambr., and cuspidata, BL, 

 .ire held to be co-generic, Gomicularia, Menge, must sink as a 

 synonym of Walckenaeria, Bl.
