Jensen leg. ( NHMD ); 1 ♂, 1 ♀ , Pará , Santarém , Taperinha , 9 Nov. 1970 , O. Jensen leg. ( NHMD ). COLOMBIA : 1 juv. , Sierra Nevada de Sta Marta , near Duriameina , ca 3600 m , 7 Dec. 1978 , under stones, H. Sturm leg. ( NHMD ); 1 juv. , E. Cordillera , Monterreanda mountain forest, ca 2000 m , 31 Dec. 1955 , litter, H. Sturm leg. ( NHMD ). These specimens are clearly Columbianum . Those from Brazil are very similar to C. major sp. nov. , although rather smaller in size and with fewer tergites. One mature male has well-developed gonopods but only 55 +1 tergites. The female in the same sample has 72 + 1 tergites. Those from Colombia are also similar in head shape and overall morphology to C. major sp. nov. but tiny in comparison, one with just 26 +1 tergites, and appear to be from rather a different habitat.
