Acholotermes socialis (Sjostedt) comb. n. 



Eutermes socialis Sjostedt, 1899:38. LECTOTYPE $ imago, CAMEROUN: Mungo River 

 (Naturhistoriska Riksmuseum, Stockholm), here designated [examined]. 



This species is catalogued in the genus Pericapritermes by Snyder (1949). Silvestri 

 (1914) transferred it to Anoplotermes on the basis of specimens other than the type- 

 series. Sjostedt (1926) placed it in Pericapritermes, where it has remained, with 

 the name in common use for a well known West African species. Emerson examined 

 the remaining specimen of the type-series in the Sjostedt collection in 1952 and 

 labelled it as the lectotype of Anoplotermes socialis (Sjostedt) but the designation 

 has not been published until now. 



This specimen was not examined until after the completion of the present work 

 and too late for inclusion in the key to Acholotermes, to which it is now assigned. 

 It agrees with Acholotermes chirotus in most of its measurements and complex ratios, 

 and runs down to that species in the key. However, it differs in having a slightly 

 longer postclypeus, a more elongate oval fontanelle, and larger ocelli. The lectotype 

 specimen of A. socialis is broken into several pieces, the compound eyes are col- 

 lapsed, and it is much faded from long preservation, adding to the difficulties of 

 comparison. The more important worker caste is not available. In view of its 

 poor condition, and the wide separation of the type-localities of the two species (1300
