We describe two new species of Neostrengeria Pretzmann, 1965, N. bataensis, from Santa María, Boyacá Department, and N. celioi, from Aguazul, Casanare Department, on the eastern slope of the Eastern Andes. With the addition of the new species, the number of species in the genus rises to 23. These new species are distinguished from their congeners primarily by the morphology of the first male gonopod, particularly by the shape of the lateral and accessory lobes, outline of apex, mesocaudal projection and mesial lobe. The genus Neostrengeria is endemic to Colombia and is distributed in both slopes and the high plain of the Eastern Cordillera, at elevations ranging from 470 to 3000 m. We present a key for the identification of the species based essencially on the morphology of the first male gonopod and pereopods.

A new species of freshwater crab of the pseudothelphusid genus Neostrengeria Pretzmann, 1965, A^. perijaensis, is described and illustrated. This discovery means the genus now contains a total of 17 species and 2 subspecies, all endemic to the Eastern Andes of Colombia. The general characteristics of the genus are given, and a key for the identification of the species based primarily on the morphology of the male first gonopod, is presented.

A new species of the genus Strengeriana Pretzmann, 1971, is described. With the addition of the new species, this genus now includes 15 species, distributed in the Sierra Nevada de Santa Marta, and the Western, Central and Eastern Cordilleras of the Colombian Andes, at altitudes ranging from 700 to 1800 m above sea level. The species are distinguished by morphological characteristics of the first male gonopod.
A new species of the genus Neostrengeria Pretzmann, 1965, N. lemaitrei from Magdalena Valley, Cundinamarca Department, is described. The genus is endemic to the Eastern Andes of Colombia, at altitudes ranging from 300 to 300 m above sea level. With the addition of N lemaitrei the total number of species rises to 21. This new species, like all others in Neostrengeria, is distinguished primarily by the morphology of the first male gonopod, partic ularly by the form of lateral and accessory lobes, and the shape of the apex.
New species of freshwater crabs from the Andes (Crustacea: Decapoda: Pseudothelphusidae)
Three new species of Pseudothelphu sidae are described from the Andes. Strengeriana tolimensis n. sp, belongs, with four other species, to a primitive group of crabs of the Central Cordillera of Colombia. Hypolobocera quevedensis n. sp. is closely related to H. ratbbuni PRETZMANN 1968, both from the western slopes of the Andes of Ecuador. Hypolobocera brevipenis n. sp. forms a natural series with four other species from the eastern slopes of Ecuador and Peru. • During a recent trip throughout the Andes, the junior author had the oppor tunity of collecting freshwater crabs at several localu.es. in Colombia, Ecuador and Peru. Among this material are several interest! ivz specimens, in particular a new species of the genus Strengeriana. This genus groups the most primitive members or the Pseudothelphusidae still surviving in South America, according to an hypotnesis recently formulated !w RODRIGUEZ (in press). The addition of a fourth species to the genus not only completes the pictur...

Two new species of freshwater crabs of the pseudothelphusid genus Neostrengeria Pretzmann, 1965, N. fernandezi n. sp., and N. lassoi n. sp., are described. The genus is endemic to the eastern Andes of Colombia. Neostrengeria fernandezi was collected in Las Cacas cave, Pauna, Boyacá Department and N. lassoi in a stream within Los Aviones cave, La Guadalupe, Santander Department, within the cave as well as in a waterfall outside the cave. With the addition of N. fernandezi and N. lassoi the total number of species of the genus Neostrengeria increases to 27. Like all others species of Neostrengeria, the new species are distinguished primarily by the morphology of the first male gonopod, particularly by the form of lateral, accessory and mesial lobes, outline of the apex, and the mesio-caudal projection of the spermatic channel.

We describe a new species of Strengeriana Pretzmann, 1971, S. villaensis, from Villahermosa, Tolima Department, on the eastern slope of the Central Andes. The genus is endemic to Colombia and is distributed in the Sierra Nevada de Santa Marta and the Western and Central Andes, at elevations ranging from 700 to 2000 m. With the addition of S. villaensis the total number of species in the genus rises to 16. This new species is distinguished from its congeners primarily by the morphology of the first male gonopod, particularly by the shape of the mesial, cephalic and lateral lobes, and the mesial and cephalic processes. We present a key for the identification of the species of the genus based on the morphology of the first male gonopod and the third maxilliped.
New species of freshwater crabs (Crustacea: Decapoda: Pseudothelphusidae) from Colombia
Proceedings of the Biological Society of Washington., 1984
Tv^o new species of Pseudothelphusidae are described from Colombia. Strengeriana chaparralensis, n.sp. adds a fifth species to a primitive group of crabs from the Central Cordillera; its gonopod resembles that of its nearest geographic relative, S. tolimensis Rodriguez and Diaz, 1981. Chaceus davidi, n.sp. also belongs to a small genus of primitive crabs from the Sierra de Santa Marta; the gonopod has characters of both Chaceus and Hypolobocera. A geographical record is given for Hypolobocera martelatani Pretzmann, 1965, which was originally described from an unknown locality in "Columbia.
