New acanthodrilid earthworms of genera protozapotecia and trigaster from Cuba (annelida, crassiclitellata)
Four new Cuban species of the family Acanthodrilidae are described from west (Protozapotecia angelesae sp.nov.), center (Protozapotecia centralis sp.nov., Protozapotecia cubensis sp.nov.) and east (Trigaster setarmata sp.nov.) regions. The new species are closely related to northeast and east Mexico...

| description | Four new Cuban species of the family Acanthodrilidae are described from west (Protozapotecia angelesae sp.nov.), center (Protozapotecia centralis sp.nov., Protozapotecia cubensis sp.nov.) and east (Trigaster setarmata sp.nov.) regions. The new species are closely related to northeast and east Mexico (Protozapotecia and Zapatadrilus) and Puerto Rico and Virgin Islands earthworms (Trigaster). Whereas new Protozapotecia species possess two gizzards and holonephridia, Trigaster setarmata sp.nov. has three gizzards and meronephridia. Protozapotecia angelesae sp.nov. is separated from all Mexican species of the genus by the absence of typhlosole and penial setae and by presence of free lamellae in the esophagus of 11 and 12. The presence of penial setae and typhlosole relates the other two new Protozapotecia species to Mexican worms; from all of them, Protozapotecia cubensis sp.nov is separated by a dorsal pore in 4/5, free calciferous lamellae in 13 and a lateral spermathecal diverticulum, whereas Protozapotecia cubensis sp.nov. is differentiated by last hearts in 13 and calciferous lamellae in segments 13, 14 and 15. Trigaster setarmata sp.nov. is separated from the four recognized species of the genus by the presence of penial setae and racemose prostatic glands. Clarification of the origin of Cuban acanthodrilids (dispersion or vicariant events) will depend on future sampling and on the elaboration of robust molecular phylogenies. |

Se describen cuatro nuevas especies de la familia Acanthodrilidae del oeste (Protozapotecia angelesae sp.nov.), centro (Protozapotecia centralis sp.nov., Protozapotecia cubensis sp.nov.) y este de Cuba (Trigaster setarmata sp.nov.). Las nuevas especies están cercanamente relacionadas con la fauna del noreste y este de México (gé- neros Protozapotecia y Zapatadrilus) y de Puerto Rico e islas Vírgenes (Trigaster). Las nuevas especies de Protozapotecia se caracterizan por tener dos mollejas y holonefridios, mientras que la especie nueva de Trigaster presenta tres mollejas y meronefridios. Protozapotecia angelesae sp.nov. se separa de las especies mexicanas del género por carecer de tiflosol y quetas peneales y por presentar láminas esofágicas libres en los segmentos 11 y 12. Por la presencia de quetas peneales y tiflosol, las otras dos especies nuevas de Protozapotecia se acercan más a la fauna mexicana; mientras que Protozapotecia centralis sp.nov. se separa de todas ellas por el poro dorsal anterior en 4/5, las láminas esofágicas libres en el segmento 13 y el divertículo espermatecal lateral sésil, Protozapotecia cubensis sp.nov. se diferencia por los últimos corazones en el segmento 13 y por las láminas esofágicas libres en los segmentos 13,14 y 15. Trigaster setarmata sp.nov. se separa de las cuatro especies conocidas del género por presentar quetas peneales y próstatas racemosas. Clarificar el origen de la fauna de acanthodrilidos cubanos (dispersión o vicarianza) dependerá de futuras colectas y de contar con filogenias moleculares robustas Instituto de Ecología, A.C. 2017-05-23 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Original articles Artículos originales application/pdf text/html https://azm.ojs.inecol.mx/index.php/azm/article/view/1014 10.21829/azm.2017.3311014 ACTA ZOOLÓGICA MEXICANA (N.S.); Vol. 33 No. 1 (2017); 67-75 ACTA ZOOLÓGICA MEXICANA (N.S.); Vol. 33 Núm. 1 (2017); 67-75 2448-8445 0065-1737 eng spa https://azm.ojs.inecol.mx/index.php/azm/article/view/1014/1216 https://azm.ojs.inecol.mx/index.php/azm/article/view/1014/1199 Derechos de autor 2017 ACTA ZOOLÓGICA MEXICANA (N.S.) http://creativecommons.org/licenses/by-nc-sa/4.0 |
