Genus REDL1CHOPS Richter & Richter, 1941 



Type SPECIES. Redlichia (Redlichops) blanckenhorni Richter & 

 Richter, 1941, by original designation. 



DISCUSSION. Redlichops is a poorly known genus. When Chang 

 [=Zhang] (1966) and Zhang et al. (1980: 79) reviewed redlichiid 

 trilobites they referredRedlichops with doubt to the Pararedlichiinae, 

 mainly because both the anterior and posterior ends of the palpebral 

 lobe are set rather far from the glabella. Even so, Redlichops differs 

 from other Pararedlichiinae in the great width of the interocular area 

 of the fixigena and in the recurved palpebral lobe, features matched 

 or exceeded only by the aberrant Metaredlichiiney/ngva/zg/fl (Zhang 



etal. 1980: pi. 31, figs 7, 10. 1 1). However, the glabella oiRedlichops 

 is not comparable with the parallel-sided or clavate glabella of the 

 Metaredlichiinae, and the genus is here retained provisionally in the 

 Pararedlichiinae, following Chang (in Whittington et al.. 1997: 

 440).

Material. The species is based on fragmentary material from the 

 type locality. Khirbet el Burj. Dr W. Struve kindly made available 

 plaster casts of the holotype (Senckenberg Museum, Frankfurt-am- 

 Main X1287a; Fig. 7) andaparatype (XI 287b). New material from 

 Wadi Qunai referred to the species is somewhat weathered but is
