A New Species

SummaryClusia falcata (Clusiaceae), a new species from Chiapas, Mexico, is described and illustrated. This new taxon is distinctive for its leaves, among the narrowest of all known species, having lanceolate to oblong laminas that are mostly 10 – 15 × 2 – 2.5 cm. The flowers have a quadrangular perianth with succulent petals, and a non-resiniferous androecium and gynoecium. Staminate flowers have a quadrangular androphore bearing 18 – 24 short stamens. Pistillate flowers have 4 pairs of staminodia, with each pair born on an androphore. The species is endemic to montane forests of the Northern and Eastern highlands of Chiapas in Mexico and is currently considered to be endangered.

A New Species

The recent discovery of a new species of land iguana in the Galapagos (Tzika et al. 2008; Gentile et al. 2009; Gentile & Snell 2009) is indeed an exciting novelty, of great interest to all zoologists and evolutionary biologists. This species being apparently represented only by a very small population with a very limited range, it was described as a new taxon following an unusual procedure: no fixed specimen(s) (holotype or syntypes) was deposited in a permanent collection, but a live specimen, in which a transponder had been inserted and which then had been released, was designated as holotype. As analysed in detail by Dubois & Nemésio (2007), because of the unclear wording of Art. 16.4.2 of the Code, whether such a nomen is nomenclaturally available is open to question, and pending a clarification of the published Rules of the Code, will remain so. In this context, some comments on the paper by Gentile & Smell (2009), from a taxonomic and nomenclatural point of view, are in order. I thank Zhi-Qiang Zhang, Chief Editor of Zootaxa, for inviting me to contribute to this discussion.

A new species of Dracula (Pleurothallidinae: Orchidaceae) from Colombia is described, honoring Irmelin Indenbirken, mother of the actor and philanthropist Leonardo DiCaprio. D. irmelinae is phenotypically most similar to Dracula verticulosa, but differs in having larger and wider sepals that form a smoothly curved semicircular mentum behind the lip, an indumentum with dark red internal and external maculae and dense long pubescence on the internal sepal surfaces and bases of the tails. The geographic distributions of the two species also differ, with the new species being restricted to a small area in the western Cordillera of Colombia. The conservation status of the new taxon is assessed as Endangered (EN) according to the International Union for Conservation of Nature (IUCN) criteria. Key words: Colombia, Dracula, endangered species, Pleurothallidinae, Western Andes

Insight Into

Abstract The late Paleozoic temnospondyl Sclerocephalus formed an aquatic top predator in various central European lakes of the late Carboniferous and early Permian. Despite hundreds of specimens spanning a wide range of sizes, knowledge of the endocranium (braincase and palatoquadrate) remained very insufficient in Sclerocephalus and other stereospondylomorphs because even large skulls had unossified endocrania. A new specimen from a stratigraphically ancient deposit at St. Wendel in southwestern Germany is recognized as representing a new taxon, S. concordiae new species, and reveals a completely ossified endocranium. The sphenethmoid was completely ossified from the basisphenoid to the anterior ethmoid region, co-ossified with the parasphenoid, and the basipterygoid joint was fully established. The pterygoid bears a slender, S-shaped epipterygoid, which formed a robust pillar lateral to the braincase. The massive stapes was firmly sutured to the parasphenoid. In the temnospondyl endocranium, character evolution involved various changes in the epipterygoid region, which evolved distinct morphologies in each of the major clades.

Basal Structure

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

Freshwater Diatom

During a survey of the freshwater diatom flora of the sub-Antarctic region (Iles Kerguelen and Iles Crozet) in the southern Indian Ocean, an unknown Cyclotella taxon was observed that was formerly identified as the presumed cosmopolitan C. meneghinana. Detailed morphological analysis based on light and scanning electron microscopical observations and comparison with several similar Cyclotella taxa worldwide justified the description of this unknown taxon as a new species: Cyclotella deceusteriana sp. nov. The new taxon is characterized by the presence of marginal fultoportulae on every costa, hyaline furrows between the raised marginal parts on which the striae are located, 2, occasionally 1, 3 or 4 central fultoportulae and an entirely flat, smooth, relatively small central area. The new species is described and compared with other Cyclotella taxa. Notes on its distribution and ecology are added.

A New Species

In May 2020, a new taxon of Euphorbia, Euphorbiaceae was collected from a dry hillside of Dongsheng District, Ordos City, Inner Mongolia. The morphological characteristics of the specimens analyzed differ from those of the known Euphorbia species from this region; therefore, we suspected this may be a new species, and we set to analyze the ITS2 sequences of some Euphorbia species. The results show that the new taxon belongs to the sect. Esula of Euphorbia subg. Esula. It is similar to Euphorbia esula (description from Flora of China) but does not belong to the same species. Concomitantly, plant morphological data and pollen morphology results show significant differences between the new taxon, E. esula and E. caesia, a finding that supports the delimitation of this new taxon, which is named Euphorbia mongoliensis in accordance with its geographical distribution.

A new species of Andinobates (Dendrobatidae) is described from the East Andes of Colombia, just 37 km away from the Colombian capital, Bogotá. Andinobates supata sp. nov., represents the second known species of yellow Andinobates, and can be distinguished from the other, Andinobates tolimensis, by an unique combination of ventral and dorsal color patterns. Our phylogenetic analyses, based on ≈ 1120 bp from two mitochondrial markers (16S rRNA and cytochrome b) showed that this new taxon is sister to a clade formed by A. cassidyhornae, A. bombetes, A. opisthomelas, A. tolimensis and A. virolinensis. The new species appears to be restricted to a handful of small forest fragments (<10 ha) distributed in no more than 5 km2, between 1800–2000 m elevation, where the human activity is high. In addition, more than 90% of the original forest has been logged at the type locality, and its watersheds receive considerable agrochemical discharges. Altogether, the evidence suggests that this new species should be listed as Critically Endangered and should receive immediate attention regarding basic research and urgent conservation measures.

A new species of Chirocephalus collected in temporary freshwater ponds in Northeastern Algeria is described. Chirocephalus sanhadjaensis sp. nov. seems to be restricted to Ain-Magroun and Belkroun pools (Skikda Province). The most similar species is C. marchesonii Ruffo & Vesentini, 1957, which is endemic to Italy. The new taxon, belonging to the “diaphanus” species group of the genus Chirocephalus, is identifiable from all congeners primarily by the shape of the antennal appendages and that of the apex of the distal antennomere of the antennae. The resting eggs of C. sanhadjaensis sp. nov. are similar to those of C. diaphanus or C. salinus but are larger (448.24 ± 30.93 µm). The restricted distribution of this species confirms the high biological diversity of the area of the Guerbes-Sanhadja eco-complex.
