Lago-Barcia D, Silva MS, Carbayo F. Revision and description of six species of Choeradoplana (Platyhelminthes, Tricladida), with an emendation to the genus. Zookeys 2021; 1016:1-48. [PMID: 33628077 PMCID: PMC7892534 DOI: 10.3897/zookeys.1016.59617] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 12/29/2020] [Indexed: 11/12/2022] Open
Abstract
Living representatives of the Neotropical genus Choeradoplana Graff, 1896 (Geoplaninae, Tricladida, Platyhelminthes) are easily recognized by the typical shape of the head which is laterally expanded, rolled-up, and ventrally provided with two glandular cushions. In this study, the morphology and phylogeny (cytochrome C oxidase subunit I gene) of several species of land planarians are taxonomically investigated. Four of the six species studied are new to science, namely: Ch. eudoxiae Silva & Carbayo, sp. nov., Ch. claudioi Lago-Barcia & Carbayo, sp. nov., Ch. onae Lago-Barcia & Carbayo, sp. nov., and Ch. riutortae Lago-Barcia & Carbayo, sp. nov. The species Choeradoplana albonigra and Ch. eudoxiae deviate from the usual body shape pattern in that the head does not present lateral expansions nor glandular cushions, becoming indistinguishable from its sister genus Cephaloflexa. Pseudogeoplana tristriata (Schultze & Müller, 1857) is also redescribed from a newly collected specimen and was discovered to be a member of Choeradoplana. Graff (1899) also studied another specimen that was considered to be conspecific with P. tristriata; however, in this new it is concluded that it is not conspecific but rather a new species. The name Pseudogeoplana aevipandemiae Lago-Barcia & Carbayo, sp. nov. is suggested for Graff's specimen.

[PMID: 32687493 PMCID: PMC7371199 DOI: 10.1371/journal.pone.0235949] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Accepted: 06/07/2020] [Indexed: 12/02/2022] Open
Abstract
Areas of endemism (AoE) are the main study units in analytical biogeographic methods, and are often defined as an area with two or more endemic species living in them, presenting substantial congruence among their range limits. We explored the distribution of land planarians (Geoplanidae, Platyhelminthes) across the southern region of the Brazilian Atlantic forest (from the state of Rio de Janeiro, to the state of Rio Grande do Sul) utilizing DaSilva's et al. (2015) protocol. We used two methods, Endemicity Analysis (EA), and Geographical Interpolation of Endemism (GIE). We identified nine AoE of terrestrial flatworms in the Southern Atlantic forest. Performance of the methodologies is discussed. These AoE of land planarians can be explained through vicariance events combined with their physiological and ecological own limitations. Interestingly, these AoE are congruent with fine-scale approaches such as that with harvestmen. Most land planarians have revealed to present a very small distributional range evidencing their potential as a good model for fine-scale studies of AoE.

Abstract
Abstract
Land flatworms usually show low ability to disperse and high endemicity, displaying many singletons in studies on land planarian assemblages. Thus, many species have been described based on specimens sampled in a single locality and/or on a few specimens. Based on phylogenetic analyses of concatenated COI and 18S rRNA genes and morphological analyses, a new genus and species of geoplaninid land planarian is described from central–east Argentina and southern Brazil. Winsoria gen. nov. shows, among its most outstanding features, a ventral cephalic retractor muscle and a subneural muscle layer that extends throughout the anterior region of the body. In addition, characters of the reproductive system and the phylogenetic analyses support the erection of this new genus. According to molecular phylogenies,Winsoria bipatria sp. nov. is closely related to species of Luteostriata, Supramontana and Issoca, taxa that also possess a cephalic retractor muscle. Despite its disjunct distribution, phylogenetic analyses, genetic divergence and morphological features show that the allopatric populations studied herein belong to a single species. We argue that the occurrence of W. bipatria in localities separated by hundreds of kilometres and a geographical barrier should be explained by passive dispersal.

Abstract
The genus Choeradoplana Graff, 1896 encompasses 16 species, most of them found in Brazil. Herein two new species of this genus are described from remnants of Araucaria moist forests, located in the states of Paraná and Santa Catarina, south Brazil. Both species resemble the type-species of the genus, C.iheringi, showing brownish dorsal surface covered by dark-brown flecks. However, regarding their anatomy, the new species differ from C.iheringi and other congeners by a long and horizontal disposed permanent papilla. In such aspects, both species resemble C.benyai, but differ from this species, as well as from each other, in details of the prostatic vesicle, ejaculatory duct, and penis papilla.
