Summary

Ceratozamia is a neotropical genus in the Cycadales that is particularly diverse in Mexico. In this genus, most species are endemic to Mexico and most of these species have a restricted distribution pattern. We propose and describe a new species from western Oaxaca State, Mexico, which was previously subsumed under the concept of C. robusta. The circumscription of this new species derived from a review of two associated taxa: C. robusta Miq. and C. leptoceras Mart.-Domínguez, Nic.-Mor., D.W.Stev. & Lorea-Hern. We conducted an extensive review of herbarium specimens, complemented with ex profeso fieldwork, during which we monitored populations in Oaxaca for phenological characterisation. The new species is described and illustrated. This species occurs in a wide distribution range of cloud forest in western Oaxaca. We provide a taxonomic key for all species with morphological and geographical affinity to C. oliversacksii and all species distributed in Oaxaca. The description of C. oliversacksii increases diversity in this cycad genus to six species in Oaxaca. This research highlights the study and monitoring of reproductive structures for robust taxonomic work.

ETYMOLOGY. The specific epithet is in memory of the distinguished neurologist and historian of science Oliver Sacks (1933 – 2015), who loved cycads and publicised them through a popular book, Island of the Color Blind and Cycad Island (Sacks 1997) and his love of Oaxaca as exemplified in his book, Oaxaca Journal, a book on the natural and cultural history of Southern Mexico with an emphasis on ferns (Sacks 2002).

Abstract

During the review of the Brazilian species of Lorostemon (Clusiaceae), we verified that some specimens previously reported as L. bombaciflorus Ducke for South Guyana and the Brazilian Eastern Amazonia belong to a species still unknown to science. Here, we provide a description, taxonomic comments, illustrations, and a distribution map of Lorostemon roseoviridis Fer.-Silva & L.Marinho, a new species from eastern Amazonia.

Keywords: Diversity, Flora, Guttiferae, Lorostemon roseoviridis, Symphonieae

TYPE: Guyana: Upper Takutu-Upper Essequibo Region. Acarai Mts., summit of unnamed peak, ...

Etymology. The epithet refers to the predominant colors found in the flowers and derives from the Latin roseus (pink) and viridis (green). Ducke (1935) published the first species name in the genus as "L. bombaciflorum", indicating that Lorostemon would be neuter, but Art. 62.2 (a) of the ICN (Turland et al., 2018) states that compound generic names ending in -stemon are masculine.

[Botany • 2024] Wedelia figueiredoana (Asteraceae: Heliantheae) • A winged cypselae New Species of Wedelia for Brazil

Wedelia figueiredoana V.R.Bueno,

in Bueno, Rodrigues, Sousa, Souza, Marzinek et Marques, 2024. 

DOI: doi.org/10.3897/phytokeys.249.135699

Abstract

We describe one new species from Ceará state, Brazil: Wedelia figueiredoana. It is morphologically associated with W. bonplandiana, but distinguished by 0.25–1.05 cm leaf blade width (vs. 1.5–2.6 cm), linear to narrow oblong leaf blade (vs. elliptic to spatulate), 3-seriate involucre (vs. 2-seriate), and cypselae 3.9–4 mm long (vs. 6–7 mm). An anatomical analysis of cypselae is provided, and we propose a more accurate terminology to describe similar wings to Wedelia species. We also provide a scientific illustration of the new species, photos of habitat, a map of its geographic occurrence, and its taxonomic affinities are discussed with a taxonomic key to the Wedelia species with the apically pronounced wings in the cypselae.

 Wedelia figueiredoana V.R.Bueno, sp. nov.

Diagnosis: Wedelia figueiredoana morphologically resembles W. bonplandiana by 0.25–1.05 cm leaf blade width (vs. 1.5–2.6 cm), linear to narrow oblong leaf blade (vs. elliptic to spatulate), 3-seriate involucre (vs. 2-seriate), and cypselae 3.9–4 mm long (vs. 6–7 mm).

Etymology: The epithet “figueiredoana” is in honor of Dr. Marlene Feliciano Figueiredo, born in 1963, a dedicated educator at Universidade Estadual Vale do Acaraú (UVA). Her dynamic engagement in teaching, research, and outreach, notably the Pensando Verde project, has left an indelible mark. Noteworthily, she was pivotal in founding and curating the Herbário Francisco José de Abreu Matos–HUVA (1998–2004), a vital botanical resource in Northwest Ceará. In botanical research, Figueiredo specializes in phanerogam taxonomy, floristics, ethnobotany, and seed germination ecophysiology, fostering a deep understanding of Northwestern Ceará’s intricate flora through her mentorship.

DOI: doi.org/10.3897/phytokeys.249.133737

Abstract

Alocasia roseus is described as a new species from Aceh Besar Regency, Sumatra (Indonesia). The plants found produce stunning inflorescence, leading to over-collecting in the wild. The new species is morphologically similar to A. flemingiana but differs by its greyish green adaxial leaves and pale reddish to greenish purple or pale brownish green abaxial leaves, lacking interprimary veins and sinus not naked, thecae overtopped by synconnective, and a pale pink appendix. The new species is also similar to A. arifolia, from which it differs by the glabrous and pale dull green petiole, the colour of abaxial and adaxial leaves, not forming interprimary vein, sinus not naked, and pale pink appendix. The new species is compared with other similar Indonesian taxa and an identification key to the species of Alocasia in Sumatra, supplemented with photographs, are provided.

Abstract

We present two new species, Hohenbergia alba and H. sparsiflora, endemic to the Brazilian Atlantic Forest in the southern region of the state of Bahia. These species were identified as understory epiphytes in forest fragments near highways. These newly described species are morphologically similar to the “giant Hohenbergia species group”, characterized by their significantly larger size compared to species found in the highlands and dryer environments. Notable unique features include the compact rosette and a 3-4-branched inflorescence with white-colored petals for H. alba and sparsely-flowered spikes for H. sparsiflora, a feature not yet reported for the genus. Additionally, we provide illustrations, and a comparative table of morphological data of these species and related taxa, as well as information on the conservation status and phenology.

Abstract

Melanoneura Fraser, 1922 is a genus of damselflies which was, to date, regarded as monotypic. It is represented by the nominate species, Melanoneura bilineata Fraser, 1922 which is endemic to the Western Ghats in India. We describe the population of Melanoneura in the Agasthyamalai landscape of the Western Ghats as a species new to science based on differences in the structure of male cerci, mesostigmal plates, genital ligulae, and the structure and marking of the prothorax. Subtle differences in body markings are also documented. Further, we demonstrate a significant genetic distance (7.2–7.4%) between the new species and M. bilineata, based on mitochondrial Cytochrome Oxidase I analysis. Our study combines morphological and genetic evidence to describe a new species belonging to the genus Melanoneura, cancelling its monotypic nature.

Phalangipus somnathensis

Sureandiran, Karuppasamy & Suyani, 2024

DOI: doi.org/10.1163/15685403-bja10423

Abstract

A new species of spider crab is described based on a single specimen collected from the Veraval fishing harbour, Gujarat, north-west coast of India, Arabian Sea. Globally nine species of spider crabs were reported of which four, Phalangipus filiformis, P. hystrix, P. indicus and P. longipes were documented from Indian waters. The new species, P. somnathensis sp. nov. differs from most species of the genus, based on the presence of blunt spines over the lateral & dorsal margin of the carapace, by the intestinal region being produced into a sharp spine, and by possessing a unique shape of male pleopod, i.e., branched into two lobes distally. The newly discovered species is compared with its congeners.

Abstract

New taxonomic and faunistic data on the agelenid spiders of Turkiye and the Caucasus are provided. Five species are described as new to science: Maimuna antalyensis sp. nov. (♂♀; Turkiye: Antalya), Tegenaria ballarini sp. nov. (♂♀; Turkiye: Antalya), T. beyazcika sp. nov. (♂; Turkiye: Antalya), T. egrisiana sp. nov. (♂♀; Georgia: Imereti), and T. hoeferi sp. nov. (♂♀; Armenia: Kotayk). Tegenaria lazarovi Dimitrov, 2020, syn. nov. is proposed as a new junior synonym of T. averni Brignoli, 1978. Persiscape caucasica (Guseinov, Marusik & Koponen, 2005) is newly reported from Armenia, and T. chumachenkoi Kovblyuk & Ponomarev, 2008 is reported for the first time from Turkiye. New distribution records for T. dalmatica Kulczyński, 1906, T. hamid Brignoli, 1978, T. longimana Simon, 1898 and T. percuriosa Brignoli, 1972, and topotype material for T. tekke Brignoli, 1978 are reported. The record of Eratigena fuesslini (Pavesi, 1873) from Turkiye is found to be based on a misidentification, and is herein attributed to T. hamid. The presence of an embolic spine, unknown in any other species of Tegenaria, is documented in T. anhela Brignoli, 1972 for the first time. Photographs are provided for all treated species.

Abstract

The Zambezi grunter, Parauchenoglanis ngamensis, is currently distributed across four (sub)basins in southern and south-central Africa, namely the Okavango, upper Zambezi, Kwanza, and Kasai. The present study used a combination of molecular (barcoding), colour pattern, and other morphological data to explore the possible existence of hidden species diversity within this species. Based on the available samples, analyses of molecular data uncovered seven well-supported (.96–1.00 Bayesian posterior probabilities) candidate species, with 1.6%−8.5% genetic divergence between them. These, in addition to two more candidate species without genetic data, exhibited a combination of consistent colour pattern and other morphological differences that supported their distinction. The present study redescribes P. ngamensis, which is confined to the Okavango and upper Zambezi (sub)basins, and describes eight new species: two from the Kwanza Basin and six from the Kasai sub-basin. The fact that some of the species occur allopatrically, whereas others are sympatric and even syntopic indicates the complex palaeogeographical history of these basins. In addition, the high species diversity discovered in the Kasai sub-basin seems to be related to its highly peculiar hydrography. Accurate delimitation of species boundaries and mapping of their distribution is crucial for conservation assessments and guiding their protection.

A. Parauchenoglanis patersoni

This species is named in honour of Dr. Angus Paterson, who was the Managing Director of the NRF-South African Institute for Aquatic Biodiversity (NRF-SAIAB) the time this paper was accepted. The name acknowledges Dr. Paterson’s dedication to developing taxonomic expertise and advancing ichthyological research in the poorly explored regions of southern Africa.

B. Parauchenoglanis ernstswartzi

This species is named in honour of Dr. Ernst Swartz, recognising his significant contributions to ichthyology, including the collection of specimens used in this study. Dr. Swartz’s pioneering exploration of the Kwanza and Kasai basins was instrumental in the discovery of several new species.

C. Parauchenoglanis dolichorhinus

The name ‘dolichorhinus’ is derived from the Greek words “dolichos” meaning “long,” and “rhinus” meaning “snout”. This name refers to the notably long snout of this species compared to others in the P. ngamensis group.

D. Parauchenoglanis poikilos

The name of this species is derived from the Greek adjective “poikilos,” which means “spotted”. The numerous distinctive spots along its body are a key characteristic of its identification.

E. Parauchenoglanis megalasma

The name of this species is derived from the Greek words “mega” meaning “large,” and “melasma” meaning “black spot”. It refers to the prominent, large black blotches along its lateral line.

G. Parauchenoglanis lueleensis

The suffix “-ensis” means “lives in” and refers to the Luele River in the Kasai sub-basin, where this species is found.

H. Parauchenoglanis luendaensis

Named after the Luenda River in the Kasai sub-basin, this species also carries the suffix “-ensis,” indicating the region it inhabits.

I. Parauchenoglanis chiumbeensis

This species is named after the Chiumbe River, which is also located in the Kasai sub-basin. The name acknowledges the region as the habitat of this newly identified species.

[Invertebrate • 2024] Erinaceusyllis simonlledoi • A New Species of Erinaceusyllis (Annelida: Syllidae) discovered at A Wood-fall in the eastern Clarion-Clipperton zone, central Pacific Ocean

Erinaceusyllis simonlledoi 

Nilsson, Wiklund, Glover, Bribiesca-Contreras & Dahlgren, 2024  

DOI: doi.org/10.1016/j.dsr.2024.104415

Highlights: 

• A novel polychaete species was discovered on an abyssal wood-fall.

• Its high abundance on degraded wood displays a tolerance to sulfidic environments.

• Morphology and genetics support placement in Erinaceusyllis of the family Syllidae.

• This constitutes the first finding of abundant syllids on a natural wood-fall.

• Sulfide-tolerant syllids in the East Pacific may originate from the same lineage.

Abstract

In the deep sea, organic falls provide temporary localized enrichments of organic matter to the otherwise nutrient-poor abyssal seafloor. Areas where organic falls land become ephemeral patches of increased biodiversity. Often rich in opportunistic species which are tolerant to the sulfidic environment formed from anaerobic breakdown of organic matter. On a wood-fall at abyssal depths in the eastern Clarion-Clipperton Zone, the novel species Erinaceusyllis simonlledoi (Annelida: Syllidae) was discovered in high abundance. This study entails the first description of a novel syllid species found in high density on a naturally occurring organic fall. Phylogenetic position was investigated using three genetic markers (16S, 18S, COI) and morphology was studied through light- and scanning electron microscopy. Genetic data and morphological analysis supported placement in the syllid genus Erinaceusyllis. Distinguishing features were lack of eyes, dorsal brooding of one egg per egg-bearing segment, lack of visible papillae across the body, incomplete fusion of palps, bidentate chaetae, as well as pyriform antennae and tentacular cirri. Erinaceusyllis simonlledoi sp. nov. is highly similar to a species found on hydrothermal vents belonging to the closely related genus Sphaerosyllis. The similarity between the two species, as well as findings of unspecified Sphaerosyllis species in various types of sulfidic habitats evoke questions of a possible syllid lineage adapted to sulfidic environments.

Abstract

For the first time, we obtained for the first time a COI DNA barcode from museum specimens of the Old World swallowtail butterfly endemic to Taiwan, Papilio machaon ssp. sylvina, that has disappeared since the devastating Jiji earthquake in 1999 that shook Central Taiwan. We demonstrate that this population was not only phenotypically distinct, but also had a unique mitochondrial haplotype among all other Holarctic populations of P. machaon. The life history of P. m. sylvina from rearing experiments carried out in the 1990s is illustrated and discussed.

Abstract

Curcuma diversicolor Soonthornk., a new species of subgen. Curcuma (Zingiberaceae, Zingiberoideae) from northern Thailand, is described and illustrated. It differs from its morphologically closest species C. globulifera by e.g. having larger flowers and the presence of coma bracts. Detailed descriptions based on living flowering material, images, and notes on distribution, habitat, and phenology are provided. Its conservation status is provisionally assessed as Data Deficient (DD). In addition, notes are provided on the distribution of the recently described C. sirirugsae, and its conservation status is reassessed based on new collections.
