Butler established Spidia for a single new species, fenestrata. Aurivillius (1906) 

 added divisa, Strand (1912) excentrica, and Gaede (1914) fenestriculata. The present 

 author (Watson, 1957) synonymized Hemictenarcha Warren, 1898, as a junior 

 synonym of Spidia Butler, 1878, sank fenestriculata as a synonym of fenestrata, 

 relegated divisa to subspecific rank {fenestrata subsp.), described goniata as a new 

 subspecies of fenestrata and transferred excentrica to Phalacrothyris Warren, 1899. 



Phalacrothyris, which was erected for a new species subviridis, is treated as a 

 junior synonym of Spidia in this paper. Warren (1902) subsequently added smithi, 

 and Gaede (1927 b : 292) transferred excentrica from Spidia to Phalacrothyris. Gaede 

 (1931) listed smithi and subviridis under Phalacrothyris and excentrica under both 

 Phalacrothyris and Spidia. 



Viette (1954 : 79) added vohilava to Spidia but it has been found necessary to 

 establish a new genus Oretopsis for this Madagascan species (see page 145). 



Three new species are added to Spidia in this revision and Thymistida miserrima 

 Holland is transferred to Spidia from Epicampoptera Bryk, bringing the total 

 number of included species to nine.
