IDENTIFICATION 



With so few specimens extant, the variability of R. bequaerti 

 cannot be determined. "" 



Males . This sex is easily recognizable by complete absence 

 of lateral grooves that are replaced by a line of large pionctations 

 bounding the raised lateral ridge. Medium-size scutal punctations 

 are arranged linearly like those of R. simus but are interspersed 

 with numerous fine interstitial punc'^ations . The posteromedian 

 groove is long and narrow, the paramedian grooves are curved and 

 wider. The cervical pits are short, deep, and punctiform. The 

 adanal shields are L shaped with a heavy, broad base, convex 

 internoanterior margin, and other margins straight with rounded 

 junctures. Coxa I has a small but distinct dorsal projection. 

 The original description states that the spixrs of coxa I are 

 "strikingly short" but the illustration accompanying the des- 

 cription hardly verifies this statement. Color is reddish- brown. 



Females . The scutum is approximately as wide as long and 

 its posterior margin is abruptly rounded. Lateral grooves are 

 greatly reduced, being restricted to the anterior half of the 

 scutum; bordering these grooves the lateral ridges rise sharply. 

 Cervical pits are wide and deep; cervical grooves reach almost 

 to the posterior scutal margin. Punctations are large and widely 

 scattered, interstitial pvinctations are stronger than in the male. 

 The basis capituli is twice as wide as long, with rightangled lat- 

 eral angles and short, rounded comua; large porose areas are 

 circulair or subcircular and spaced apart from each other by less 

 than their ovm diameter (in R. s. simus , these are small, circular, 

 and spaced far apart). ~ ~ 



A small dorsal process of coxa I is present on the Sudan spec- 

 imen, thovigh this process is stated to be absent on the type fe- 

 male. Eyes of the Sudan specimen are situated on the scutal mar- 

 gin, dark amber color, elongately oval, very slightly convex, and 

 delimited by a shallow groove along the internal border. The 

 Svdan specimen was identified by Dr. G. Theiler.
