Schiilze (1936G) compared the body outline of A. brumpti with 

 that of certain fossil trilobites that it happens to resemble. 



IDENTIFICATION 



Neumann's original adult specimens from Ethiopia measured 

 from 15 mm. to 20 mm. long and from 10 ram. to 13 mm. wide. The 

 size range among available Sxidan and Egyptian females is from 

 10 mm. to 12 mm. long and from 7 mm. to 8 mm. wide. The dorsal 

 integument is marked most distinctively by large, symmetrical 

 polygonal depressed areas boimded by rugose ridges; laterally 

 the dorsal integument is evenly striated. A continuous, clear, 

 and distinct sutural line divides the dorsal and ventral sur- 

 faces. Discs, which are small and inapparent, lie in clumps or 

 lines in the integumental depressions, and short hairs are scat- 

 tered anteriorly and posteriorly on the periphery of the body. 

 The outline of the body is subquadrangular with parallel lateral 

 margins, a bluntly rounded posterior margin, and a pointed pro- 

 jection of the anterior margin over the mouthparts. Tarsus I has 

 two dorsal humps and the other tarsi each have a prominent sub^ 

 apical dorsal protuberance. Males have a narrow, rounded genital 

 aperture; females have a transversally elongate, narrow genital 

 orifice. 



The nymph closely resembles the adiilt, except for size and 

 absence of genital aperture. The larva has been described by 

 Cunliffe (1914B) and by Hoogstraal and Kaiser (1956).
