A New Species

A new species of Phallangothelphusa Pretzmann, 1965, is described from the foothills of the Serranía Yariguíes, Santander Department, Magdalena river basin, Colombia. The number of the species increases to five: P. dispar (Zimmer, 1912), P. magdalenensis Campos, 1998, P. juansei Campos, 2010, P. martensis Cardona & Campos, 2012, and P. tangerina n. sp. The new species is distinguished from its congeners mainly by the morphology of the first male gonopod, particularly by the shapes of the mesial and lateral processes, and the surface and outline form of the apex.

The Relationship

A new genus and species of pseudothelphusid crab of the tribe Kingsleyini Ortmann, 1897, from the Tapajós River, a southern tributary of the Amazon River basin in the state of Pará, Brazil, is described and illustrated.Michaelthelphusa tuerkayigen. et sp. nov. is characterized by the male first gonopod possessing marginal and lateral sutures fused at the distal third of the stem and the merged portion strongly twisted towards the lateral side; an apex transversally expanded along caudal-cephalic axis, with a well-developed, but low, somewhat depressed, apical plate; apical plate with spine-like outgrowth cross overlapping the spine-like projection of the mesial process. Moreover, the relationship of the new genus and species with other pseudothelphusid genera from the Amazon basin is discussed.
