Vervoort (1963 b, p.110) is convinced that the species originally recorded by T. Scott (1894, p.27) from the Gulf of Guinea as P. pygmaeus cannot possibly be identified with P. crassirostris Dahl, 1894. A study of the topotypic Atlantide material has made quite clear that the differences between Dahl's and T. Scott's foroms are even larger than those mentioned by Früchtl; so that in the Vervoort's opinion T. Scoot's species should receive specific rank.; it is particularly characterized by the short, fairly highly vaulted cephalothorax, the thick, 2-pointed rostrum terminating into acute points, the structure and length of A1 and the spinulation of the legs. In the Atlantide specimens the separation between the 4th and 5th thoracic somites is distinctly marked; A1 reach the end of the caudal rami and the terminal segment is about 1.5 times as long as the penultimate segment. The legs are remarkable by the 1-segmented condition of the endopodite of P1; the number of setae (6) on this endopodite is not reduced. | | | Last update : 07/04/2018 | |
