Columbianum cf. major

Material studied

BRAZIL: 1 ♂ Pará, Santarém, Taperinha , 16 Nov. 1970, S.L Tuxen and O. 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.
