[Botany • 2023] Goniothalamus hmoope (Annonaceae) • A Third Species of Goniothalamus from New Caledonia and Lectotypification of G. obtusatus


 Goniothalamus hmoope Munzinger & D.M. Johnson,  

in MunzingerJohnson et Saunders, 2023. 

A new species is described from New Caledonia in the genus Goniothalamus, which now includes three endemic species from the archipelago. The new species was first collected over 150 years ago, but had not been subsequently studied until now. Material of the New Caledonian taxa was included in a recent molecular phylogeny, which shows that they are related and belong to the same clade, but they are easily distinguished from one another by morphology. Goniothalamus hmoope sp. nov. differs from G. obtusatus by its smaller leaves and its monocarps that are terete and 3-8 seeded (vs narrowly ellipsoid, ellipsoid, subglobose to obovoid, 1-3-seeded), and from G. dumontetii by its flat leaves with plane secondary veins (versus slightly bullate with impressed venation), and its monocarps that are terete (vs flattened elongate with lateral triangular projections). The new species, which is restricted to the North Province and can be abundant in the Mt. Panié range, was assessed by the New Caledonian Red List Authority as Vulnerable (VU) based on the IUCN Red List criteria.

Abstract
The pterosaur assemblage of the mid-Cretaceous Kem Kem Group of Morocco is reviewed. This analysis examines their taxonomy, palaeoecology and palaeobiology with comments on taphonomy. New material permits the rediagnosis of the azhdarchoids Alanqa saharica and Afrotapejara zouhrii. Several specimens are reported that do not fit within the paradigms of previously named taxa. They represent three distinct jaw morphotypes, but are not assigned to new taxa here. The assemblage is highly diverse, including four tooth-bearing taxa assigned to Ornithocheiridae and five named taxa and three additional morphotypes assigned to Azhdarchoidea. The Kem Kem Group assemblage is the most diverse for any pterosaur-bearing fluvial deposit and one of the most diverse of any pterosaur assemblage. The assemblage is heavily biased in terms of preservation with an as yet unexplained high abundance of jaw fragments. We highlight the importance of fragmentary material in pterosaur studies.

[Arachnida • 2023] Flagelliphantes yunxiaA newly recorded genus with description of A New Cave-dwelling Species of Flagelliphantes (Araneae: Linyphiidae) from northeastern China


 Flagelliphantes yunxia Yao & Irfan,

in Yang, Yao, Irfan et He, 2023. 

Abstract
Background: The genus Flagelliphantes Saaristo & Tanasevitch, 1996 was proposed by Saaristo & Tanasevitch, 1996 to accommodate three ex-Lepthyphantes species distributed in northern Eurasia. Male Flagelliphantes are easlily recognised by having a hood-shaped thumb on the embolus. The females have a long, S-shaped scape and the posterior median plate of the epigyne is grossly enlarged (“hypertrophied”).

New information: While examining Linyphiidae Blackwall, 1859 specimens from Yunxia Cave in China’s Jilin Province, we discovered a new cave-dwelling species of the genus FlagelliphantesF. yunxia sp. n. In this paper, we provide detailed description and photos of its diagnostic somatic and genitalic features. It is the first record of the genus from China.

Keywords: biodiversity, description, morphology, sheet-web spiders, taxonomy


Flagelliphantes yunxia Yao & Irfan, sp. n.

Diagnosis: The new species resembles Flagelliphantes flagellifer (Tanasevitch, 1988) described from the Kolyma Upland in northeastern Siberia by Tanasevitch (1988). In both cases, the male palps have similar ribbon-shaped “lamella characteristica”, both apically abruptly broadened with serrated margin; the epigynes are also similar with a broad, S-shaped scape (Figs 1, 2, 3; Tanasevitch (1988), figs 12, 14 and 15). The males of the two species can be distinguished by the following: apical part of terminal apophysis oval in the new species (Fig. 1A, Fig. 2A and B) vs. apical part elongated in F. flagellifer (Tanasevitch (1988), figs 12 and 13); apex of pit hook with seven teeth in the new species (Fig. 1A, Fig. 2A and B) vs. apex bifurcated in F. flagellifer (Tanasevitch (1988), fig. 12); lamella characteristica of F. flagellifer is much wider apically than in the new species (Fig. 1A, Fig. 2A and B; Tanasevitch 1988, fig. 13). The females can be distinguished by the following: posterior median plate as long as the proscape (Fig. 3) vs. half the length of proscape in F. flagellifer (Tanasevitch (1988), figs 14 and 15).

Etymology: The specific name refers to the type locality; noun in apposition.

Distribution: China (Jilin).

Biology: The species was found in the aphotic zone inside cave.

in Tu, Furey, Görföl, Hassanin, Arai, ... et Csorba, 2023. 

Abstract
This study integrates analyses of mitochondrial DNA sequences and morphological and acoustic data to re-evaluate the taxonomic status of Rhinolophus rex rex, R. r. paradoxolophus and R. schnitzleri throughout their distribution ranges. Based on a dense geographic sampling of specimens hitherto referred to these taxa and contrary to the current taxonomic view, our results indicate that all examined specimens of these taxa are representatives of a single, widely distributed and morphologically variable species, R. rex. The recognition of its geographic populations as different subspecies (R. r. rex and R. r. paradoxolophus) or distinct species (R. schnitzleri) based on morphological and acoustic data should be regarded as invalid. In the light of this revision, we also reassess the conservation status of R. rex against IUCN Red List criteria as Near Threatened.

[Botany • 2023] Vochysia wilsonii (Vochysiaceae, sect. Ciliantha) • A New Species from the Colombian Amazon Forest


Vochysia wilsonii Marc.-Berti, J.M. Vélez. & Aymard,

in Marcano-Berti, Vélez-Puerta et Aymard-Corredor, 2023.

Abstract
A new species of Vochysia, V. wilsonii (section Ciliantha, subsection Ferruginea), is described, and its morphological relationships with other similar Vochysia species are discussed. Vochysia wilsonii is found in wet forests over sandstone tabletop outcrops (“Mesetas”) and white sand soils in the Araracuara (“medio río Caquetá”) and Chiribiquete areas, a megadiverse region in the Colombian Guayana Shield, Caquetá department. This new species is a tree up to 25 m tall, and shares features with four species (Vochysia biloba, V. casiquiarensis, V. sabatieri, and V. vismiifolia). However, it differs in the size and shape of the leaves, stipules, inflorescence, cincinni, spur, spurred sepal, flower, central petal and stamen, as well as in its pubescence size and shape. An updated key of 45 Colombian species of Vochysia is provided.

Vochysia wilsonii Marc.-Berti, J.M. Vélez. & Aymard, sp. nov. 

 Vochysia wilsonii resembles V. biloba, V. casiquiarensis, V. sabatieri and V. vismiifolia, but can be differentiated from these species by having leaves obovate to obovateelliptic, 7.0–14.2 × 4.2–6.0 cm, apex emarginated, truncate to truncate-emarginate, short mucronate, base obtuse, lateral veins 24–29, at a 50˚– 60˚ angle with the midrib, stipules triangular, inflorescences 16–19 cm long, cincinni 3-flowered, rarely 2- or 4-flowered, spurred sepal 1.3–1.4 cm long, spur 6.5–7 mm long, subsigmoidal, and stamen glabrous dorsally, laxly pubescent on internal surface.

Etymology: Vochysia wilsonii is named after Wilson Rodríguez, a most enthusiast Colombian botanist, with an extraordinary knowledge of the floras of the Amazon and Orinoco river basins, of neotropical ferns, and, more recently, of Vochysiaceae.

 Common names: The name “Peraikz” (Uitoto) was recorded on the specimen Sastre & Raichel-Dolmatoff 4956.

[Ichthyology • 2023] Rhyacoglanis benineiDescription and Phylogenetic Position of A New Species of Rhyacoglanis (Siluriformes: Pseudopimelodidae) from the Jamanxim River Basin


 Rhyacoglanis beninei
Crispim-Rodrigues, Silva, Shibatta, Kuranaka & Oliveira, 2023 


Abstract
In this study, a new species of Rhyacoglanis is described from the Jamanxim River basin, Tapajós River basin. The new species differs from congeners based on the combination of the following diagnostic characters: two oblique dark bands formed by an agglomerate of melanophores on the predorsal region; dorsal confluence between the dark subdorsal and subadipose bands in large juveniles and adults; ventral confluence between the dark subadipose and caudal peduncle bands; body without conspicuous dark brown spots; complete dark band on caudal peduncle; body with three dark bands; a thin dark caudal-fin band; pectoral-fin spine with anterior serrae distributed along the entire margin; the posterior tip of the post-cleithral process reaching vertical through the base of the dorsal-fin spine; and hypural 5 free of hypural 3 and 4 and pointed caudal-fin lobes. Additionally, our molecular phylogenetic results using ultraconserved elements (UCEs) corroborate the new species as Rhyacoglanis and sister to an undescribed species of Rhyacoglanis from the Xingu River basin. Moreover, as pointed out in previous studies, we confirm Cruciglanis as a sister group to Pseudopimelodus plus Rhyacoglanis.

Rhyacoglanis beninei, new species
 
Diagnosis. Rhyacoglanis beninei can be diagnosed from all congeners by two oblique dorsal dark brown bars on the predorsal region (Fig. 2) (vs. absent). Additionally, R. beninei is distinguished from some congeners by having a dorsal confluence between the dark subdorsal and subadipose bands in large juveniles and adults (> 28 mm SL) (vs. lack dorsal confluence in R. paranensis, R. annulatus, R. varii, and R. rapppydanielae); ventral confluence between the dark subadipose and caudal peduncle bands (vs. lack ventral confluence in R. annulatus, R. epiblepsis, R. paranensis, R. seminiger, and R. rapppydanielae); body without conspicuous dark brown spots (vs. conspicuous dark brown spots in R. epiblepsis and R. rapppydanielae); complete dark band on caudal peduncle (vs. caudal peduncle-band with a unpigmented central region in R. annulatus); body with three dark bands (vs. two dark bands in R. seminiger); a thin dark caudal-fin bands (vs. large caudal-fin bands in R. paranensis and R. epiblepsis); pectoral-fin spine with anterior serrae distributed along the entire margin (restricted to the proximal half in R. pulcher and R. seminiger); posterior tip of the post-cleithral process reaching vertical through the base of the dorsal-fin spine (vs. not reaching in R. epiblepsis and R. rapppydanielae); hypural 5 free of hypural 3 and 4 (vs. hypurals 4 and 5 fused in R. rapppydanielae); pointed caudal-fin lobes (vs. rounded lobes in R. epiblepsis).

Etymology. Rhyacoglanis beninei is named in honor of Ricardo Cardoso Benine, Professor at Universidade Estadual Paulista “Júlio de Mesquita Filho”, in recognition of his dedication and remarkable contributions to the knowledge of Neotropical freshwater fishes.

Abstract
A new species of holothurian, Elpidia soyoae sp. nov., is described from the Japan Trench area, at depths of 3570–4145 m. It is distinguished from its congeners in having: four or five paired papillae and unpaired papillae present along entire dorsal radii (four to seven papillae on each radius), with wide separation between second and third paired papillae; maximum length of Elpidia-type ossicles in dorsal body wall exceeds 1000 µm; axis diameter of dorsal Elpidia-type ossicles less than 40 µm; tentacle Elpidia-type ossicles with arched axis and shortened, occasionally completely reduced arms and apophyses. Purple pigmentation spots composed of small purple particles on both dorsal and ventral body wall. This is the second species of Elpidia Théel, 1876 from Japanese abyssal depths. The diagnosis of the genus Elpidia is modified to distinguish from all other elpidiid genera. A morphological comparison of the species of the slender axis group of genus Elpidia, and partial mitochondrial cytochrome c oxidase subunit I (COI) gene sequences of type specimens are provided.

[Botany • 2023] A New Subfamily Calasterelloideae and New Genus Calasterella for a phylogenetically and morphologically distinct member of the Aytoniaceae


Calasterella californica (Hampe ex Austin) D.G.Long & T.X.Zheng, 

in Long et Zheng, 2023.

 Abstract
Based on a phylogenetically and morphologically distinct species, a new genus Calasterella is established. A new subfamily, Calasterelloideae, is also proposed to contain this genus.

Keywords: Marchantiales, taxonomy, systematics, bryophytes 

Calasterella californica (Hampe ex Austin) D.G.Long & T.X.Zheng
(≡ Asterella californica (Hampe ex Austin) Underw.).  

 Calasterella californica (Hampe ex Austin) D.G.Long & T.X.Zheng.
 A: Immature carpocephalum from below showing deeply cleft involucres with overlapping margins of cleft. B: Mature carpocephalum from below showing pseudoperianths and dehisced sporophyte with lemon-yellow spores.
C: Scanning Electron Micrographs of the spores, distal face. D: Scanning Electron Micrographs of the spores, proximal face.
Arrow heads: involucre. Arrow: spores. 
Scale bars: A, 2 mm; B, 1 mm; C, D: 20 μm. [A: D.G. Long 45940 (E). B: D.G. Long 45333 (E). C, D: D. G. Long et al. 44666 (E)]
 
Calasterelloideae T.X.Zheng & D.G.Long subfam. nov.  

includes one genus, Calasterella D.G.Long & T.X.Zheng, gen. nov.

Diagnosis: Differs from Aytonioideae and Reboulioideae by the following combination: dioicous sexuality; strictly dichotomous branching pattern; ventral tissue with mucilage cavities; up to four appendages of ventral scale; deeplylobed female receptacle with pseudoperianths and involucre cleft to base; lemon-yellow spores with conspicuous trilete ridges, prominent equatorial wing, similar ornamentation on proximal and distal surfaces, lacking large areolae but with fine network of alveolae.

Type: Calasterella D.G.Long & T.X.Zheng, gen. nov.

Type species: Calasterella californica (Hampe ex Austin) D.G.Long & T.X.Zheng comb. nov. 
(≡ Fimbraria californica Hampe ex Austin, Hepat. bor.-amer. 33, 1873). 
≡ Asterella californica (Hampe ex Austin)

Etymology: The genus is named by the combination of the abbreviation of its main distribution region “California”,and the previous placement “Asterella”.

[Botany • 2023] Curcuma nepalensis (Zingiberaceae) • A New Species from Nepal


Curcuma nepalensis M. Sabu, Kasaju & S. Subedi, 
 
in Sabu, Kasaju et Subedi, 2023.  
 
Abstract
Curcuma nepalensis M. Sabu, Kasaju & S. Subedi (Zingiberaceae) is described from Surkhet District of Nepal and illustrated. It resembles especially C. aurantiaca in having red bracts, a similar rhizome and yellow flowers, but differs from the latter by its shorter petiole, smaller labellum and white, calcarate anthers.
