Abstract

A new species of freshwater crab, Kingsleya attenboroughi n. sp., from the Arajara district, Ceará state, Brazil, is described and illustrated. The new species differs from congeners by having a short apical plate in the first gonopod, with anteriorly directed lobes and proximally angular; proximal lobe of the apical plate with conspicuous semicircular protuberance in mesial and sternal views; marginal process protruded, projecting mesially in sternal view and subquadrate in mesial view; and field of apical spines narrow, tapering distally, with small spines concentrated proximally. Opportunity is taken to illustrate K. gustavoi Magalhães, 2005, the closest allied species of K. attenboroughi n. sp. A key for the species of Kingsleya Ortmann, 1897 is provided.

Abstract

We describe and illustrate a new species of Chaceus Pretzmann, 1965, from the Regional Natural Park of the Serranía de Perijá, La Guajira Department, Colombia. This increases the number of Chaceus species to ten, three of them with records only from Venezuela. The species of this genus are distributed in the Sierra de Santa Marta of Colombia and the Serranía de Perijá of Colombia and Venezuela. We distinguished the new species from its congeners mainly by the third maxilliped, with an exopod that is 0.60–0.62 the length of ischium, and by the morphology of the first male gonopod, particularly by the shapes of the mesial, marginal, and lateral processes. We include the distribution of the Chaceus species here and a key for the identification of the species based on the morphology of the first male gonopod.

DOI:  10.1590/S1984-46702015000100006

ABSTRACT
Kingsleya castrensis sp. nov., a pseudothelphusid crab is described and illustrated from the Xingu River, state of Pará, southern Amazon region, Brazil. The new species is characterized by the male first gonopod bearing a large, well-developed apical plate, with a broadly rounded, thick distal lobe. New records of Kingsleya junki Magalhães, 2003 extend the distribution of this species eastward to the Tocantins River basin, in the state of Pará, Brazil.

Key words: Amazon; Brachyura; Kingsleyini; Neotropical region; taxonomy

 Kingsleya castrensis sp. nov., male, paratype, MZUSP 26394:
(7) habitus, dorsal view; (8) habitus, ventral view; (9) frontal view; (10) pair of third maxillipeds, frontal view. Male, paratype, left first gonopod, MZUSP 23393: (11) caudal-mesial view; (12) mesial-cephalic view; (13) lateral view; (14) idem, caudal view.

Scale bars: 7, 8 = 10 mm, 9, 10 = 5 mm; 11-14 = 1 mm.

 Kingsleya castrensis sp. nov.

Diagnosis. G1 with large, roughly rounded, thick apical plate, widest medially; proximal lobe of apical plate subtriangular, well developed, situated on mesio-caudal side; distal margin straight, stretching diagonally over the distal lobe, fusing to mesiodistal portion of apical plate; distal lobe of apical plate broad, with lateral margin angulate in mesial view, caudal margin straight, distal margin slightly concave, mesial margin rounded, thick.

Etymology. The specific epithet refers to castra, the Latin word for military camp, in reference to the Brazilian Army battalion camp where this species was found.
