The land planarians in the genus Obama include the largest species of the Neotropical Geoplaninae. Morphological discrimination of Obama species can be difficult, as many species are morphologically similar and some present asymmetric \– difficult to interpret \– copulatory organs. New techniques are thus welcomed to provide faster species description and identification. Here, we study several specimens of Obama by means of mainly 2D and 3D \μCT-based images obtained through X-ray microcomputed tomography (\μCT) of a paratype, and, complementarily, histological sections of the holotype and a second paratype, which were digitized into virtual slides. Comparison of these images with traditional histological sections and descriptions of the known species of the genus allows us to conclude that our specimens constitute a new species, which we describe here. We further evaluate the phylogenetic placement of the new species using gene fragments from the mitochondrial cytochrome c oxidase subunit I and the nuclear elongation factor-1\α. Raw and derivative \μCT data and virtual histological sections were deposited in an open repository (GigaDB) and are freely available. This work leads us to conclude that \μCT constitutes a relatively fast, inexpensive non-destructive method that produces results comparable to those of traditional histology, and is thus amenable for describing flatworm species.

A small sample of freshwater triclads from streams and pools of the Gebel Marra volcanic massif in the Western Sudan was examined by the author. All specimens showed the general features characteristic of triclads within the \“arrow-headed\” Dugesia group. The specimens serially examined show a number of less conspicuous features not agreeing with those described in other Dugesia forms reported from African localities. A description has been given and as a new species name Dugesia sudanica has been proposed. The new species would, according to the author, represent a further \“microspecies\” within the \“superspecies\”Dugesia gonocephala.

The new species Dugesia notogaea Sluys \& Kawakatsu, sp. n. is described from Queensland, Australia, representing the first record of the genus Dugesia for that continent. A phylogenetic analysis of the 68 species of Dugesia resulted in the discovery of a new apomorphy for the genus, and a cladogram showing two major phyletic groups. The distributional range of one group has a western accent, whereas that of the other group has an eastern emphasis; the ranges of these two groups overlap in Africa and the Mediterranean region. We attempt to determine the ancestral area for both the Dugesiidae and Dugesia. A scenario for the historical biogeography of the genus Dugesia is discussed. In this scenario it is presumed that the geological history of the Australasian region enabled Dugesia\’s from southeast Asia to colonize northern Australia.
