          Abstract

          Se analizó la comunidad de metazoos parásitos de S. chiliensis de la costa marina peruana. Se recolectaron 100 especímenes de S. chiliensis del Terminal Pesquero de Chorrillos, Lima, Perú, entre enero de 2013 y diciembre de 2014 y se realizó la necropsia para estudiar su comunidad de metazoos parásitos. Los cestodos dominaron en riqueza de especies y en porcentaje de individuos colectados (N=5; 44.6%), seguido de los nematodos (N=4; 27.0%), acantocéfalos (N=3; 2.3%), trematodos (N=1; 23.2%) y finalmente los copépodos parásitos (N=1; 3%). Los endoparásitos dominaron (97%) frente a los ectoparásitos (3%). El 21.4% del total de parásitos colectados fueron formas maduras de metazoos de localización branquial y gastrointestinal y el 78.6% correspondió a formas larvarias. Los tres parásitos con mayor importancia específica (prevalencia y abundancia media) de 14 taxas encontradas fueron Sphyriocephalus tergestinus, Anisakis sp2 y Unitubulotestis pelamydis. La longitud total de S. chiliensis no presentó asociación entre la prevalencia y abundancia de dos parásitos, a excepción de U. pelamydis que observó relación entre la prevalencia y la talla del pez. La comparación entre los valores de k n (factor de condición relativo) entre peces parasitados y no parasitados de S. chiliensis, mostró diferencias para los tres parásitos, presentándose mayores valores en los no parasitados. Los valores de diversidad alfa mostraron mayores valores en las hembras que en los machos de S. chiliensis. Los valores de Chao-2 indican que en el componente comunitario se requiere incrementar el tamaño de la muestra debido a que se espera encontrar hasta 18 especies (22% adicionales)

          Metazoan parasite community of S. chiliensis of Peruvian shoreline was analyzed. Specimens of S. chiliensis (n=100) were collected from Fishing Terminal of Chorrillos, Lima, Peru between January 2013 and December 2014. Necropsies were conducted to study their metazoan parasite community. Tapeworms dominated species richness and percentage of collected individuals (N=5; 44.6%), followed by nematodes (N=4; 27.0%), acanthocephalan (N=3; 2%), flukes (N=1; 23.2%) and finally the parasitic copepods (N=1, 3%). Endoparasites dominated (97%) against ectoparasites (3%). The 21.4% of collected parasites were mature forms of metazoan gill and gastrointestinal location and 78.6% were larval forms. The three parasites with more specific importance (average prevalence and abundance) of 14 taxa were Sphyriocephalus tergestinus, Anisakis sp2 and Unitubulotestis pelamydis. The total length of S. chiliensis did not presented association between prevalence and abundance of two parasites, except for U. pelamydis that showed a relationship between the prevalence and size of the fish. The comparison between the values of k n (relative condition factor) between parasitized and non-parasitized S. chiliensis showed differences for the three parasites, having higher values in non-parasitized. The values of alpha diversity showed higher values in females than in males of S. chiliensis. Values of Chao-2 show that in the community component is required to increase the sample size because was expected to find up to 18 species (22%)

            Classification of the acanthocephala.

            O Amin (2013)
            In 1985, Amin presented a new system for the classification of the Acanthocephala in Crompton and Nickol's (1985) book 'Biology of the Acanthocephala' and recognized the concepts of Meyer (1931, 1932, 1933) and Van Cleave (1936, 1941, 1947, 1948, 1949, 1951, 1952). This system became the standard for the taxonomy of this group and remains so to date. Many changes have taken place and many new genera and species, as well as higher taxa, have been described since. An updated version of the 1985 scheme incorporating new concepts in molecular taxonomy, gene sequencing and phylogenetic studies is presented. The hierarchy has undergone a total face lift with Amin's (1987) addition of a new class, Polyacanthocephala (and a new order and family) to remove inconsistencies in the class Palaeacanthocephala. Amin and Ha (2008) added a third order (and a new family) to the Palaeacanthocephala, Heteramorphida, which combines features from the palaeacanthocephalan families Polymorphidae and Heteracanthocephalidae. Other families and subfamilies have been added but some have been eliminated, e.g. the three subfamilies of Arythmacanthidae: Arhythmacanthinae Yamaguti, 1935; Neoacanthocephaloidinae Golvan, 1960; and Paracanthocephaloidinae Golvan, 1969. Amin (1985) listed 22 families, 122 genera and 903 species (4, 4 and 14 families; 13, 28 and 81 genera; 167, 167 and 569 species in Archiacanthocephala, Eoacanthocephala and Palaeacanthocephala, respectively). The number of taxa listed in the present treatment is 26 families (18% increase), 157 genera (29%), and 1298 species (44%) (4, 4 and 16; 18, 29 and 106; 189, 255 and 845, in the same order), which also includes 1 family, 1 genus and 4 species in the class Polyacanthocephala Amin, 1987, and 3 genera and 5 species in the fossil family Zhijinitidae.
