ETYMOLOGY ­ The specific designation spinicauda is derived from the Latin spini = spine, thorn, and from the Latin cauda = tail, referring to the microtuberculate caudal dorsoopisthosomal annuli. REMARKS ­ C. spinicauda is the third species with microtuberculate caudal dorsoopisthosomal annuli, together with C. cissi Keifer, 1978 and C. deleoni ( Keifer, 1956 ) . C. cissi has 4­rayed empodia and the median and admedian lines form four pairs of cells on the prodorsal shield, whereas in C. deleoni and C. spinicauda empodia are 5­rayed and no cells are delimited by the prodorsal shield lines. C. deleoni has complete median and admedian lines on the prodorsal shield, while in C. spinicauda only a complete median line is present. In C. deleoni the epigynium is large, covering the entire genital area and is densily spinulate; in C. spinicauda the epigynium is much shorter than the genital area and presents only a few spinules.
