 black punctures and black spots on posterior angles. Legs sometimes tinged with green. 

 Hemielytra tinged with black. Abdomen with dorsum pale, tinged with brown, venter pale 

 ochraceous, sometimes reddish anteriorly. Posterior margin of seventh abdominal tergum 

 regularly curved, pygophore rounded with apex pointed. 



o* genitalia : Claspers broad towards base, external surface curved only in middle (Text- 

 figs. 19 and 20) ; ventral thecal appendage as in Text-fig. 21 ; four left lateral conjunctival 

 appendages as in Text-fig. 21 ; frontal appendage bifurcated in middle, sometimes left branch 

 longer ; four right lateral conjunctival appendages as in Text-fig. 21 with spine-like appendage, 

 thicker at base and apex ; dorsal appendage thick and curved at base as in Text-fig. 21.

 5-8-6-0 mm. ; distance between ocelli 0-46 mm., distance between an ocellus and an eye, 

 0-7 mm. 



Very similar in general appearance and colour but distinctly longer than $ ; seventh 

 abdominal sternum with small median parallel-sided notched projection. 



$ genitalia : First gonocoxae thicker in middle and curved near apex with round apices ; 

 intervalvular sacs absent, spermatheca flask-shaped with long neck (Text-fig. 25). 



Material studied. Mauritius : 1 <J, 2 $ ; Seychelles : 1 $ ; Madagasgar : 

 1 $ ; Congo : 18 <$> n ?. 



The range of this species extends in the west as far as the Congo (Ituri river) and 

 in the east to Mauritius. It is also found in the Seychelles and Madagascar. It 

 has mostly been collected during the early part of the year (from December until 

 June), but it has also been taken in August. 



This species is close to distinguenda (Blote) in having similar type of paraclypeae, 

 lateral black line and the similar shape of the pygophore, but can easily be separated
