[Crustacea • 2017] Parasesarma gazi • A New Species of the Genus Parasesarma De Man 1895 (Decapoda: Sesarmidae) from East African Mangroves and Evidence for Mitochondrial Introgression in Sesarmid Crabs


Parasesarma gazi

Abstract
The Sesarmidae (Decapoda; Brachyura: Thoracotremata) is the most speciose family of crabs occurring in the mangroves of East Africa, accounting for 12 species belonging to seven genera. Among these, the genus Parasesarma accounts for a total of four species. Here we describe a new species, Parasesarma gazi sp. nov., based on specimens collected in mangrove forests of Kenya and Tanzania. The phylogenetic position of this new species within the family Sesarmidae was reconstructed, based on three mitochondrial and one nuclear marker. While nuclear data genetically resolve the systematic relationships, mitochondrial data reveal a surprising similarity of Parasesarma gazi sp. nov. and its sister species P. leptosoma. This result may reflect a short history of reproductive isolation or recent mitochondrial introgression between these two species. This is the first time that such an evolutionary event is reported for the family Sesarmidae and for mangrove crabs, in general.

GENUS PARASESARMA, DE MAN, 1895 

PARASESARMA GAZI Cannicci, Innocenti and Fratini sp. nov.
Sesarma (Parasesarma) lenzii De Man 1894.

  Etymology: The name of this new species, Parasesarma gazi, is derived from Gazi Bay (also named Maftaha Bay) and the village of Gazi, on the South coast of Kenya. In Arab, gazi or ghazi is the active participle of the verb gaza ‘to strive for’ or also ‘the one who struggles’. The new species is dedicated to the people of Gazi village and to the staff of the Gazi Mangrove Research Station of KMFRI, since without their help the largest known population of this new species would never have been found. We also believe that ‘the one who struggles’ correspondingly applies to mangrove crabs and their challenging adaptations to intertidal life, and that they are ‘key’ in mangrove ecosystems. The specific name is used as a noun in apposition.

Ecology: At all three sites, Parasesarma gazi sp. nov. was found in the Rhizophora mucronata Lamk, 1804 dominated belt of the mangrove forest, on the muddy floor. Only the specimens collected at Gazi Bay were collected on the lower part of R. mucronata roots, and there was no evidence of climbing behavior, such as in P. leptosoma. In all cases, they were found in areas where the by far dominant crab species was P. guttatum, with which they were mixing and totally overlapping.

 Bulbophyllum yunxiaoense M.H.Li, J.F.Liu & S.P.Chen,

in Li, Yuan, D.-K. Liu, J.-F. Liu et Chen, 2017. 

Abstract
We have described and illustrated a new species, Bulbophyllum yunxiaoense (Malaxideae, Epidendroideae, Orchidaceae), from Fujian Province in southeast China. The size and overall floral morphology of the new species are similar to those of Bulbophyllum pingtungense, a species endemic to Taiwan Island on the southeast coast of China and its closest relative according to a cladistic analysis of nuclear (ITS) and plastid (matK, trnL-F, and atpI-atpH) DNA sequences. However, B. yunxiaoense is distinguishable from B. pingtungense by flower colour, shorter scape, and longer lateral sepal.

[Botany • 2017] Pleroma carajasense (Melastomataceae) • A New Species endemic to Ironstone Outcrops in the Brazilian Amazon

 

Pleroma carajasense K.Rocha, R.Goldenb. & F.S.Mey.,

in RochaGoldenbergViana et Meyer, 2017.

Abstract
A new species of Pleroma from Serra dos Carajás, Pará state, Brazil, is described. Pleroma carajasense occurs in southeastern Amazonia, northern Brazil, in canga vegetation, on ironstone outcrops. It is morphologically related to Tibouchina caatingae, because both are shrubs with elliptic to oval leaves, conspicuous petioles (3–17 mm and 10–15 mm, respectively), a pair of elliptic bracteoles, and purple petals, anthers (both cycles) and style. Pleroma carajasense differs from T. caatingae by its chartaceous leaves (versus coriaceous in T. caatingae), with an obtuse to cuneate base (vs. obtuse to subcordate), hypanthium 4–7 × 1.2–4 mm (vs. 10–15 × 3–5 mm). According to IUCN criteria, this species should be considered endangered (EN). A morphological description, illustrations, photos in the field, scanning electronic micrographs of the leaf indumentum and seeds, information on conservation status and distribution are presented.

[Paleontology • 2024] Rapid Volcanic Ash Entombment reveals the 3D Anatomy of Cambrian Trilobites


Artistic reconstruction of two species of trilobite an instant before burial in a flow of volcanic ash 510 million years ago.
Gigoutella mauretanica (Ortega-Hernández, Azizi, Hearing, Harvey, Edgecombe, Hafid & El Hariri, 2017)

in El Albani, Mazurier, Edgecombe, Azizi, El Bakhouch, ... et Paterson, 2024. 

Abstract
Knowledge of Cambrian animal anatomy is limited by preservational processes that result in compaction, size bias, and incompleteness. We documented pristine three-dimensional (3D) anatomy of trilobites fossilized through rapid ash burial from a pyroclastic flow entering a shallow marine environment. Cambrian ellipsocephaloid trilobites from Morocco are articulated and undistorted, revealing exquisite details of the appendages and digestive system. Previously unknown anatomy includes a soft-tissue labrum attached to the hypostome, a slit-like mouth, and distinctive cephalic feeding appendages. Our findings resolve controversy over whether the trilobite hypostome is the labrum or incorporates it and establish crown-group euarthropod homologies in trilobites. This occurrence of moldic fossils with 3D soft parts highlights volcanic ash deposits in marine settings as an underexplored source for exceptionally preserved organisms.

Editor’s summary: Trilobites are probably the best known denizens of the Cambrian Period. Their distinctive fossilized external forms are well recognized from an extensive fossil record spanning the early Cambrian to the Permian extinction. The vast majority of trilobite fossils display only external morphology, however, leaving much unknown about their internal morphology. El Albani et al. describe several trilobite fossils created by rapid death and preservation due to an underwater pyroclastic flow. This preservation created three-dimensional fossils with a remarkably well-preserved anatomy. This enhanced understanding of trilobite anatomy has revealed several new features and provided key insights into crown group euarthropods. —Sacha Vignieri

 
COVER: This reconstruction of a shallow marine environment shows trilobites being rapidly engulfed by volcanic ash from an eruption that occurred more than 500 million years ago. Recently discovered trilobite fossils from Cambrian-aged rocks in Morocco have revealed three-dimensional soft-tissue anatomy, including features not previously observed in these extinct arthropods. This find highlights marine volcanic ash deposits as important sites of exceptional fossil preservation. || Image: A. El Albani

Abstract
The historical Godeffroy Collection of spiders at the Centrum für Naturkunde (CeNak) in Hamburg comprises several hundred type specimens from Australia and is an essential source for arachnologists around the world. In this paper, we re-describe and illustrate the Australian Oxyopes material from this collection. Most specimens were collected by C. F. Eduard Dämel for the Godeffroy Museum and described in 1871-1881 by pioneering arachnologist Ludwig Carl Christian Koch as part of the first monograph on Australian spiders: Die Arachniden Australiens. Twelve species are redescribed and properly illustrated for the first time: Oxyopes amoenus L. Koch, 1878, Oxyopes attenuatus L. Koch, 1878, Oxyopes elegans L. Koch, 1878, Oxyopes gratus L. Koch, 1878, Oxyopes gracilipes (White, 1849), Oxyopes macilentus L. Koch, 1878, Oxyopes molarius L. Koch, 1878, Oxyopes mundulus L. Koch, 1878, Oxyopes punctatus L. Koch, 1878, Oxyopes quadrifasciatus L. Koch, 1878, Oxyopes rubicundus L. Koch, 1878, and Oxyopes variabilis L. Koch, 1878. Oxyopes lautus L. Koch, 1878 is treated as a numen dubium because both palps are lost. The new species Oxyopes godeffroyi sp. n. is described from this historical material and was probably overlooked by Koch. An identification key for these species is provided and the history of these specimens reviewed briefly. A map shows the localities of the redescribed Oxyopes species and the general distribution of the Oxyopes species in Queensland.

[Arachnida • 2017] Portacosa cinerea • A New Genus for the south-east Australian Grey Wolf Spider (Araneae: Lycosidae: Lycosinae)


Portacosa cinerea  
 Framenau, 2017


Abstract
A new monotypic genus of Australian wolf spiders is proposed to accommodate the common south-east Australian Grey Wolf Spider, Portacosa cinerea gen. n. and sp. n. The genus includes large (total length 9.5–25.0 mm), uniformly grey-coloured wolf spiders with unique genital morphology, i.e. the ventral ridge of the tegular apophysis in the male pedipalp is comparatively sharp and situated towards its retrolateral edge, and the distinct anterior hood of the female epigyne is continuous with the inverted T-shaped median septum. Unlike most other members of the Lycosinae in Australia, the Grey Wolf Spider closes its burrow with a plug-like trapdoor. The species can be found in south-eastern mainland Australia (Queensland, New South Wales, Australian Capital Territory, Victoria, South Australia) and Tasmania. It prefers compacted, open and often sun-exposed habitats such as road verges and river banks, but can also be found in open woodlands and grasslands.

Abstract
Southeast Asia harbors a unique and diverse freshwater fauna of Mesozoic origin, which is under severe threat of extinction because of rapid economic development and urbanization. The largest freshwater basins of the region are certainly the primary evolutionary hotspots and they attract the most attention as key biodiversity areas for conservation. In contrast, medium-sized rivers are considered low-importance areas with secondary biodiversity, whose faunas originated via founder events from larger basins during the Pleistocene, although such a scenario has never been tested by using a phylogenetic approach. In this investigation, we used freshwater mussels (Unionidae) as a model to estimate the levels of endemism within the Sittaung, a little-known remote basin in Myanmar, compared with the surrounding larger rivers (Irrawaddy, Salween and Mekong). We discovered that the Sittaung represents an exceptional evolutionary hotspot with numerous endemic taxa of freshwater mussels. On the basis of our extensive dataset, we describe two new tribes, two genera, seven species and a subspecies of Unionidae. Our results highlight that medium-sized basins may represent separate evolutionary hotspots that harbor a number of endemic lineages. These basins should therefore be a focus of special conservation efforts alongside the largest Southeast Asian rivers.

[Crustacea • 2017] Heteromysis cancelli, H. fosteri & H. octopodis • Three New Species of Heteromysis (Mysida: Mysidae: Heteromysini) from the Cape Peninsula, South Africa, with first documentation of a mysid-cephalopod association


Heteromysis octopodis 
Wittmann & Griffiths, 2017


Abstract
Faunistic studies in sublittoral and littoral marine habitats on the Cape Peninsula, South Africa, have yielded three new species belonging to the genus Heteromysis, subgenus HeteromysisH. cancelli sp. n. associated with the diogenid hermit crab Cancellus macrothrix Stebbing, 1924, and H. fosteri sp. n. extracted from ‘empty’ urchin and gastropod shells. The first documented mysid-cephalopod association is reported for H. octopodis sp. n. which was found in dens occupied by Octopus vulgaris Cuvier, 1797, but was also captured from tide pools. The three new species differ from previously known E. Atlantic species, among other characters, by a single spine on the endopods of uropods in combination with large cornea and absence of median sternal processes on thoracic somites. They are also characterized by a white stripe along the dorso-lateral terminal margin of the eyestalks in living specimens. The new species appear quite similar to each other, but are distinguished by different depths of the telson cleft, different distributions of spines on the lateral margins of the telson, different numbers of segments on thoracic endopod 4, and by differently modified setae on the carpus of the third thoracic endopod, as well as on the carpopropodus of the fourth endopod. An updated key to the species of Heteromysis known from the E. Atlantic is given.
