This is the most widely distributed species of Erbula. Leaving aside the doubtful 

 record from Sumatra, its range extends from Sao Thome Island and Principe Island 

 in the west to Zanibar in the east and appears to comprise the whole of the African 

 equatorial belt. The adults are very common in late May and early June, but they 

 have been collected throughout the year. 



This species is close to S. (E.) annulicornis (Signoret) in general appearance and 

 colour but comparatively isolated and can be easily separated from all other species 

 of the subgenus Erbula by having very short, medially thick and curved claspers in 

 the 3, which never reach the apex of the pygophore. In the $, the round median 

 projection of the seventh abdominal sternum separates it from all other species of 

 this group. 



An examination of the material that was seen by Stal and Blote (see above) has 

 shown that Stal misidentified this species as L. apicalis Westwood, and Blote 

 correctly followed Stal's interpretation. However their specimens are not Stenocoris 

 apicalis (Westwood) (see page 38) and thus the present species, which was the type 

 of Erbula Stal, is hitherto undescribed. This species has also been recorded by 

 Southwood (1961) in light trap catches at Kawanda, Uganda. I have pleasure in 

 naming this species in honour of Dr. T. R. E. Southwood, who suggested the present 

 problem and has supervised my studies on it.
