E-mail: [email protected] ABSTRACT. A new species of Notogynaphallia Ogren & Kawakatsu, 1990, from Southern Brazil, is described. Notogynaphallia ceciliae sp. nov. has an elongated body with parallel margins and five dorsal dark longitudinal stripes on a yellowish ground. It possess branched efferent ducts, each branch opening separately into the anterior and median thirds of the long prostatic vesicle. Comparative commentaries on the most important characters of the external and internal morphology of the 23 species of the genus are also presented, so delimiting smaller inside groups. KEY WORDS.

Van Steenkiste , Elizabeth R. Herbert, Brian S. Leander Beaty Biodiversity Research Centre, Department of Zoology, University of British Columbia, 3529-6270 University Blvd, Vancouver, BC V6T 1Z4, Canada ARTICLE INFO ABSTRACT Keywords: Increasing evidence suggests that many widespread species of meiofauna are in fact regional complexes of Flatworms (pseudo-)cryptic species. This knowledge has challenged the ‘Everything is Everywhere’ hypothesis and also Meiofauna partly explains the meiofauna paradox of widespread nominal species with limited dispersal abilities. Here, we Species delimitation investigated species diversity within the marine microturbellarian Astrotorhynchus bifidus sensu lato in the turbellaria Northeast Pacific Ocean. We used a multiple-evidence approach combining multi-gene (18S, 28S, COI) phylo- Pseudo-cryptic species genetic analyses, several single-gene and multi-gene species delimitation methods, haplotype networks and COI conventional taxonomy to designate Primary Species Hypotheses (PSHs). This included the development of rhabdocoel-specific COI barcode primers, which also have the potential to aid in species identification and delimitation in other rhabdocoels. Secondary Species Hypotheses (SSHs) corresponding to morphospecies and pseudo-cryptic species were then proposed based on the minimum consensus of different PSHs. Our results showed that (a) there are at least five species in the A. bifidus complex in the Northeast Pacific Ocean, four of which can be diagnosed based on stylet morphology, (b) the A. -
View of Toba Indigenous People That Inhabit the Chacoan Negrete Et Al
Negrete et al. Zoological Studies (2015) 54:58 DOI 10.1186/s40555-015-0136-5 RESEARCH Open Access A new species of Notogynaphallia (Platyhelminthes, Geoplanidae) extends the known distribution of land planarians in Chacoan province (Chacoan subregion), South America Lisandro Negrete1,2, Ana Maria Leal-Zanchet3 and Francisco Brusa1,2* Abstract Background: The subfamily Geoplaninae (Geoplanidae) includes land planarian species of the Neotropical Region. In Argentina, the knowledge about land planarian diversity is still incipient, although this has recently increased mainly in the Atlantic Forest ecosystem. However, other regions like Chacoan forests remain virtually unexplored. Results: In this paper, we describe a new species of the genus Notogynaphallia of the Chacoan subregion. This species is characterized by a black pigmentation on the dorsum and a dark grey ventral surface. The eyes with clear halos extend to the dorsal surface. The pharynx is cylindrical. The main features of the reproductive system involve testes anterior to the ovaries, prostatic vesicle intrabulbar (with a tubular proximal portion and a globose distal portion) opening broadly in a richly folded male atrium, common glandular ovovitelline duct and female genital canal dorso-anteriorly flexed constituting a “C”, female atrium tubular proximally and widening distally. Conclusions: This is the first report of the genus Notogynaphallia in Argentina (Chacoan subregion, Neotropical Region) which increases its geographic distribution in South America. Also, as a consequence of features observed in species of the genus, we propose an emendation of the generic diagnosis.

ARTICLE DOI: 10.1038/s42003-018-0151-2 OPEN Coordination between binocular field and spontaneous self-motion specifies the efficiency of planarians’ photo-response orientation behavior Yoshitaro Akiyama1,2, Kiyokazu Agata1,3 & Takeshi Inoue 1,3 1234567890():,; Eyes show remarkable diversity in morphology among creatures. However, little is known about how morphological traits of eyes affect behaviors. Here, we investigate the mechan- isms responsible for the establishment of efficient photo-response orientation behavior using the planarian Dugesia japonica as a model. Our behavioral assays reveal the functional angle of the visual field and show that the binocular field formed by paired eyes in D. japonica has an impact on the accurate recognition of the direction of a light source. Furthermore, we find that the binocular field in coordination with spontaneous wigwag self-motion of the head specifies the efficiency of photo-responsive evasive behavior in planarians. Our findings suggest that the linkage between the architecture of the sensory organs and spontaneous self-motion is a platform that serves for efficient and adaptive outcomes of planarian and potentially other animal behaviors. 1 Department of Biophysics, Graduate School of Science, Kyoto University, Kitashirakawa-Oiwake, Sakyo-ku, Kyoto 606-8502, Japan. 2 Department of Advanced Interdisciplinary Studies, Graduate School of Engineering, The University of Tokyo, 4-6-1 Komaba, Meguro-ku, Tokyo 153-8904, Japan. 3 Department of Life Science, Faculty of Science, Gakushuin University, 1-5-1 -
The Genome of Schmidtea Mediterranea and the Evolution Of
OPEN ArtICLE doi:10.1038/nature25473 The genome of Schmidtea mediterranea and the evolution of core cellular mechanisms Markus Alexander Grohme1*, Siegfried Schloissnig2*, Andrei Rozanski1, Martin Pippel2, George Robert Young3, Sylke Winkler1, Holger Brandl1, Ian Henry1, Andreas Dahl4, Sean Powell2, Michael Hiller1,5, Eugene Myers1 & Jochen Christian Rink1 The planarian Schmidtea mediterranea is an important model for stem cell research and regeneration, but adequate genome resources for this species have been lacking. Here we report a highly contiguous genome assembly of S. mediterranea, using long-read sequencing and a de novo assembler (MARVEL) enhanced for low-complexity reads. The S. mediterranea genome is highly polymorphic and repetitive, and harbours a novel class of giant retroelements. Furthermore, the genome assembly lacks a number of highly conserved genes, including critical components of the mitotic spindle assembly checkpoint, but planarians maintain checkpoint function. Our genome assembly provides a key model system resource that will be useful for studying regeneration and the evolutionary plasticity of core cell biological mechanisms. Rapid regeneration from tiny pieces of tissue makes planarians a prime De novo long read assembly of the planarian genome model system for regeneration. Abundant adult pluripotent stem cells, In preparation for genome sequencing, we inbred the sexual strain termed neoblasts, power regeneration and the continuous turnover of S. mediterranea (Fig. 1a) for more than 17 successive sib- mating of all cell types1–3, and transplantation of a single neoblast can rescue generations in the hope of decreasing heterozygosity. We also developed a lethally irradiated animal4. Planarians therefore also constitute a a new DNA isolation protocol that meets the purity and high molecular prime model system for stem cell pluripotency and its evolutionary weight requirements of PacBio long-read sequencing12 (Extended Data underpinnings5. -
