Abstract
Sonerila quangnamensis, a new species from Truong Son Mountain Range, Vietnam, is described and illustrated here. Like S. plagiocardia, S. quangnamensis has obliquely ovate leaves, which are unequal in size within each pair. However, S. quangnamensis is obviously distinct in several characters: the cross-section of its stems and petioles is terete (vs. 4-winged), the adaxial surface of its leaves is covered with hispidulous-pilose (vs. puberulous), the hypanthium is unribbed (vs. 6-ribbed), and its anthers are uniformly yellow (vs. purple to purplish-pink, yellow-tinged towards the base).

Diagnosis: Resembling S. plagiocardia in its obliquely ovate foliage, S. quangnamensis clearly differs in several key characteristics. It has terete (vs. 4-winged) stems and petioles, hispidulous-pilose (vs. puberulous) adaxial leaf surface, unribbed (vs. 6-ribbed) hypanthium, and uniformly yellow (vs. purple to purplish-pink, yellow-tinged towards the base) anthers.

Etymology: The specific epithet refers to its type locality, Quang Nam province. The Vietnamese name “Sơn linh quảng nam” is proposed.

• Supplemental description and illustration based on living collections provided.
• P. bipiniana treated as conspecific with P. subspicata.

Abstract
Peliosanthes meghalayensis, a new species from Wari Chora gorge in Meghalaya, NE India, is described and illustrated. It is similar to P. pumila from Khasia, NE India, in its small habit and having flowers fewer than 10, but differs chiefly by the knobby rhizome, broader leaf blades with closer transversal veinlets, slightly larger cernuous flowers, and pistils with 6 distinct ridges. On the other hand, in Assam, NE India, we rediscovered P. subspicata, which had been known only by old collections made in NE India and Bangladesh in the 19th century. We supplementarily describe and illustrate it based on living collections. We treated P. bipiniana as conspecific with P. subspicata.

in D.R.P. Krahl, Schmal, Chiron, Silva, A.H. Krahl et Cantuária, 2024.
 
ABSTRACT
This study presents a new orchid species of the genus Catasetum belonging to the group of species with symmetrical and parallel antennae. It was found in terra-firme and floodplain forests in the Brazilian states of Amazonas and Pará. We provide a formal description of the new species, images, and notes on distribution, habitat, phenology, flower visitors and preliminary conservation status. We compare it with C. cristatum and C. barbatum, both sympatric and morphologically most similar to the new species. It was preliminarily classified in the Endangered (EN) category according to IUCN criteria based on the extent of occurrence, area of occupation, number of occurrence locations and the risks that the known populations are exposed to (deforestation and predatory collection).

[Paleontology • 2024] Jurassic Fossil Juvenile reveals prolonged Life History in early Mammals



in Panciroli, Benson, Fernandez, Fraser, Humpage, Luo, Newham et Walsh, 2024.

Abstract
Living mammal groups exhibit rapid juvenile growth with a cessation of growth in adulthood. Understanding the emergence of this pattern in the earliest mammaliaforms (mammals and their closest extinct relatives) is hindered by a paucity of fossils representing juvenile individuals. We report exceptionally complete juvenile and adult specimens of the Middle Jurassic docodontan Krusatodon, providing anatomical data and insights into the life history of early diverging mammaliaforms. We used synchrotron X-ray micro-computed tomography imaging of cementum growth increments in the teeth to provide evidence of pace of life in a Mesozoic mammaliaform. The adult was about 7 years and the juvenile 7 to 24 months of age at death and in the process of replacing its deciduous dentition with its final, adult generation. When analysed against a dataset of life history parameters for extant mammals5, the relative sequence of adult tooth eruption was already established in Krusatodon and in the range observed in extant mammals but this development was prolonged, taking place during a longer period as part of a significantly longer maximum lifespan than extant mammals of comparable adult body mass (156 g or less). Our findings suggest that early diverging mammaliaforms did not experience the same life histories as extant small-bodied mammals and the fundamental shift to faster growth over a shorter lifespan may not have taken place in mammaliaforms until during or after the Middle Jurassic.

[Entomology • 2020] Bulasconotus scaccarius • A New Species of cylindrical Bark Beetle (Coleoptera: Zopheridae: Colydiinae) from Vanuatu establishes in Hawaii


Bulasconotus scaccarius 
Bernard & Gillett, 2020


Abstract
We describe Bulasconotus scaccarius sp. nov., a new species of cylindrical bark beetle (Zopheridae: Colydiinae: Synchitini), elevating the number of described species in its genus to two. Despite discovering this species in Hawaii, we suspect, based on collections and survey data, that it is endemic to the South Pacific archipelago of Vanuatu and has only recently arrived in Hawaii. Evidence of the diet of closely related genera indicates that the new species may be a predator of ambrosia beetles (Curculionidae: Scolytinae), conceivably posing a risk to those that are endemic to Hawaii.

Keywords: Coleoptera, Colydiidae, invasive species, Melanesia, New Hebrides, Oahu, Tenebrionoidea

Bulasconotus scaccarius sp. nov.

Etymology. The specific epithet is the adjective form of the nominative singular noun scaccarium, meaning a chessboard, in reference to the chequered pattern on the elytra. This name thereby conforms to article 11.9.1.1 of the International Code of Zoological Nomenclature. Because the adjective suffix agrees with the masculinity of the generic name, the binomial name also conforms to article 31.2 even though the eponym is neuter.

[Botany • 2024] Eriotheca paganuccii (Malvaceae: Bombacoideae) • A New endangered Species from Montane Forests in the Atlantic Forest of Bahia, northeastern Brazil

 

Eriotheca paganuccii Carv.-Sobr., A.C.Mota & Dorr,

in Carvalho-Sobrinho, da Mota et Dorr, 2024. 

Abstract
A new species of Eriotheca (Bombacoideae, Malvaceae) from montane wet forests in the Atlantic Forest of Bahia, northeastern Brazil, is described and illustrated. It is known from only three populations situated between 750 m and 850 m in elevation on mountain summits and categorized as Endangered (EN) based on IUCN criteria. Eriotheca paganuccii is distinct from all congeners by the combination of coriaceous to strongly coriaceous leaves and remarkable few-seeded, globose to subglobose woody capsules that contain scanty kapok and the largest seeds known in the genus to date. The affinities of E. paganuccii to morphologically similar species as well as the importance of obtaining phenologically complete collections are discussed.

Key words: Bahian southern Atlantic Forest, ‘Bombacaceae’, ‘embiruçú’, endemism, plant taxonomy

Eriotheca paganuccii Carv.-Sobr., A.C.Mota & Dorr, sp. nov.
 
Diagnosis: Similar to Eriotheca obcordata A.Robyns due to its absence of buttresses, obcordate leaflets, oblong to oblanceolate flower buds, oblanceolate petals, and stamens c. 80 in number, but differing in its caducous (vs. often persistent) bracteoles, larger calyces (7 × 7–9 mm vs. 5–5 mm), globose to subglobose (vs. obovoid) capsules, scanty (vs. abundant) kapok, seed number (c. 10 vs. numerous) per fruit, seed size (10–19 mm vs. 5–7 mm) long, and marcescent, lignified calyces that often split into patent lobes (in herbarium collections, at least).


Etymology: The specific epithet honors Luciano Paganucci de Queiroz, a distinguished Brazilian taxonomist who was the first to collect this new species and one of the first to promote and undertake floristic efforts on Serra da Jiboia, Bahia, its type-locality.

[Paleontology • 2024] Propterodacylus frankerlae • A pterosaurian connecting link from the Late Jurassic of Germany

 
 Propterodacylus frankerlae
Spindler, 2024


ABSTRACT
Based on a unique and extraordinarily preserved complete skeleton, the “Painten pro-pterodactyloid” is formally described and named as Propterodactylus frankerlae, gen. nov., spec. nov. As previously shown, it has a nearly perfect mix of plesiomorphic rhamphorhynchoid-grade, wukongopterid, and derived pterodactyloid traits. Due to its lack of autapomorphies, Propterodactylus is a sufficient intermediate taxon that closes the greatest knowledge gap regarding the evolution of pterosaur morphology. Non-pterodactyloid features include interlocking caudal vertebrae and a functional fifth pedal toe. Derived features such as the nasoantorbital fenestra, a short tail, or initially elongated cervicals and metacarpals appear ancient within the spectrum of Pterodactyloidea. Other early Monofenestrata appear more autapomorphic. However, the late juvenile or subadult status of the described specimen suggests that the rostrum, neck, and extremities might have been even more elongated when fully grown. Despite the otherwise intermediate, transitional osteology, details of dentition types appear mosaic-like in early Monofenestrata. While the remainder of the skeleton of Propterodactylus fits into known evolutionary trends, its dentition implies a significant role of varying dietary adaptation throughout the pterodactyl transition.

Clade Monofenestrata Lü, Unwin, Jin, Liu, and Ji, 2010

Propterodactylus gen. nov. 

Remarks. The intermediate status is underlined by a lack of apparent autapomorphies. Tischlinger and Frey (2013) listed several plesiomorphic and apomorphic traits. Similarities with the derived Pterodactyloidea comprise the skull shape and short tail. Plesiomorphies shared with e.g., Wukongopteridae, which preclude Propterodactlyus from Pterodactyloidea, are the functional fifth toe and long caudal zygapophyses. Intermediate conditions apply to the cervical elongation, metacarpal elongation, and reduced fifth toe.

Etymology. The genus name refers to the informal designation as a pro-pterodactyloid in the literature, meaning a supposed forerunner (ancient Greek προ- for “before”) of the iconic Pterodactylus (latinized form of Greek πτερόν plus δάκτυλος for “wing digit”) and at the same time a forerunner of the Pterodactyloidea in general.


 Propterodactylus frankerlae, gen. nov., spec. nov. 

Etymology. The epithet honours Petra Hahn, née Frankerl (1966 - 2019), the wife of Stephan Hahn, who found the specimen in 2011 during the scientific excavation.

in Wang et Zhao, 2024. 

Abstract
Twenty undescribed species of Panorpa Linnaeus, 1758 from southwestern China share some morphological similarities such as basally constricted male abdominal segment VII, loss of median process in male gonostyli, and greatly developed female laterotergites IX with the little-known species Panorpa issikiana Byers, 1970. Therefore, the P. issikiana species group is established to include these species, with descriptions of the new species, a checklist, keys to the species, and a distributional map provided. These new species are: P. chenyandongi Wang sp. nov., P. dalangba Wang sp. nov., P. dimaluo Wang sp. nov., P. huadianba Wang & Zhao sp. nov., P. jinfo Wang sp. nov., P. jizushana Wang sp. nov., P. leiqilongi Wang sp. nov., P. luojishana Wang sp. nov., P. maershana Wang sp. nov., P. meihuashana Wang sp. nov., P. niaodiaoshana Wang sp. nov., P. shengyingfeng Wang & Zhao sp. nov., P. shimianensis Wang sp. nov., P. sicaura Wang sp. nov., P. vajra Wang sp. nov., P. vajroides Wang & Zhao sp. nov., P. weixiensis Wang sp. nov., P. wenhai Wang sp. nov., P. wolongensis Wang sp. nov., and P. yucheni Wang sp. nov. All of them are distributed in southwestern China, including Chongqing, Guizhou, Sichuan and Yunnan. In addition, their systematic positions are briefly discussed. The historical problems of P. issikiana, the systematic position of this group in the genus Panorpa, and the relationships among its members are also discussed.

Highlights: 
• A new species of the rare genus Sciadonus is discovered from Brazilian waters.
• Highly specialized reproductive apparatus enables internal fertilization and viviparity in a deep-sea fish.
• The depletion of sunlight resulted on convergent evolution of troglomorphic traits in deep-sea fishes and cave fishes.
• Human activities of oil and natural gas exploration, fisheries and littering may be impacting rare deep-sea species.

A new species of the rare, deep-sea genus Sciadonus Garman, 1899 (Bythitidae) is described based on two specimens obtained by the Brazilian R/V Alpha Crucis on the continental slope off São Paulo State, Southeastern Brazil, western South Atlantic. It differs from its congeners by the combination of the following characters: body pale lacking dark pigmentation except for on female claspers; a pair of dermal tissue flaps anteriorly on lower jaw; pelvic-fin rays present; precaudal vertebrae 39 or 40 and total vertebrae 74 or 75. The key to the species of Sciadonus is updated. A discussion of the presence and differentiation between troglomorphic and miniature characteristics among the species in the aphyonid clade is provided and compared with other bythitids.
