Abstract
Based on morphological and plastid data, we have described and confirmed that Coptis austrogaoligongensis distributed in Tongbiguan Provincial Nature Reserve, Yingjiang County, Yunnan Province, is a new species of Coptis. It is distinctly different from C. teeta subsp. teeta and C. teeta subsp. lohitensis with differences mainly reflected in the following features: former leaf segment lobes contiguous to each other, and lateral segments equal to central one; plants without developed stolons; inflorescences with only 1–3 flowers; petals have short claws. Phylogenetic analysis indicated that C. austrogaoligongensis is a sister to C. teeta subsp. teeta and C. teeta subsp. lohitensis.

[Ichthyology • 2024] Hypostomus cari • Integrative taxonomy clarifies the armoured catfish Hypostomus pusarum (Starks) species complex (Siluriformes: Loricariidae) and reveals A New Species in the drainages of Northeastern Brazil


Hypostomus cari
Lustosa-Costa, Ramos, Zawadzki, Jacobina & Lima, 2024

 
Abstract
Hypostomus is the most species-rich genus within the family Loricariidae and is widely distributed throughout the Neotropical region. Nonetheless, the diversity and distribution of these species have still large knowledge gaps. This scenario is more significant in some regions, such as the northeast of Brazil. In this region, the first species of the genus, H. pusarum, was described in the Northeast Caatinga and Costal Drainages ecoregion. Six congeners were subsequently described in the same ecoregion, all sharing the same colour pattern making them difficult to distinguish. All of them are collectively referred to as the H. pusarum complex. The present work seeks to clarify the diversity that constitutes the H. pusarum complex through an integrative study using molecular and morphological data. The results indicate that H. carvalhoi, H. jaguribensis, H. nudiventris, H. papariae, and H. salgadae are all junior synonyms of H. pusarum. However, one of the morphotypes that occurs in the Parnaíba River is a new species that differs from the others by the absence of a developed medial buccal papilla and the presence of a pre-anal plate. The data provided here highlight the importance of integrative taxonomy for assessing diversity in complex and diverse groups in the Neotropics.

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).

[Ichthyology • 2022] Sciadonus alphacrucis • A New Species of the rare deep-sea Genus Sciadonus Garman, 1899 (Ophidiiformes: Bythitidae) from off Brazil, with a discussion of the evolution of troglomorphism and miniaturization in the aphyonid clade


Sciadonus alphacrucis  
  Melo, Gomes, Møller & Nielsen, 2022

 
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.

Abstract
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.

[Paleontology • 2024] Hibernophis breithaupti • Morphology and Systematics of A New fossil Snake from the early Rupelian (Oligocene) White River Formation, Wyoming

 

 Hibernophis breithaupti
 Croghan, Palci, Onary, Lee & Caldwell, 2024

 
Abstract
Extinct snake taxa are recognized primarily from isolated vertebrae. A new specimen from the early Oligocene of Wyoming provides a rare opportunity to examine four nearly complete and articulated fossil snakes. Informally assigned previously to the ‘erycine’ vertebral form taxa Ogmophis and Calamagras, a detailed comparison reveals that this fossil snake exhibits vertebral differences from both taxa and is, furthermore, a new taxon, Hibernophis breithaupti gen. et sp. nov., based on a combination of apomorphies such as absence of basal tubera, low subrectangular prootic, low parasphenoid wings obscuring the anterior opening of the Vidian canal, and foramen for the mandibular branch of the trigeminal nerve posteriorly displaced inside the adductor fossa of the compound. Parsimony and Bayesian phylogenetic analysis of combined morphological and molecular data from a broad selection of snakes places Hibernophis breithaupti as sister taxon to all other booids, distant from both Old and New World ‘erycines’. However, an alternative position close to New World ‘erycines’ and ungaliophiines cannot be rejected.

[Ichthyology • 2024] Phylogeographic Patterns of Cyphocharax (Characiformes: Curimatidae) from trans-Andean Rivers and northward expansion to lower Central America

  

Cyphocharax spp.

in Melo, Conde-Saldaña, Villa-Navarro, McMahan et Oliveira, 2024.

Abstract
Phylogenetic analyses of mitochondrial and nuclear data of 31 specimens of Cyphocharax from trans-Andean rivers support the presence of one lineage of Cyphocharax aspilos in Lago Maracaibo and three cryptic lineages of Cyphocharax magdalenae: (1) Cauca-Magdalena and Ranchería, (2) León and Atrato, and (3) Chucunaque-Tuira, Santa María, and Chiriquí basins of Central America. Results suggest that the Serranía del Perijá facilitated Late Miocene cladogenetic events, whereas post-Isthmian C. magdalenae expansion was enabled by gene flow across the lower Magdalena valley and Central American lowlands. Time-calibrated phylogenetics indicate that the C. magdalenae colonized lower Central America in the Pliocene (3.7 MYA; Ma), the divergence Atrato-Magdalena occurred in Late Pliocene (3.0 Ma) and the split Ranchería-Magdalena during the Middle Pleistocene (1.3 Ma). Updated geographic distribution data support the hypothesis that the Cordillera de Talamanca functions as a barrier to northward expansion of C. magdalenae in Central America.

in Mediodia, Chang, Ho, Přikryl & Lin, 2024. 

A new species of splitfin fish, Synagrops atrumoris sp. nov., from Dongsha Island, Taiwan, South China Sea, is described based on its morphological characteristics, including osteology and otolith morphology, and DNA sequence. Synagrops atrumoris sp. nov. is closely similar to Synagrops japonicus and can be distinguished by its black mouth cavity covering the lower portion of the tongue, posteriorly enlarged and complex basioccipital fossae, and a triangular otolith with a strong postero-dorsal angle, as well as a strong genetic difference. In addition, the taxonomy of the genus Synagrops was revised. Available published data, together with our results, suggest that S. bellus is a synonym of S. japonicus.

[Entomology • 2024] Excastra albopilosa • A remarkable New Genus and Species of Lamiinae (Coleoptera: Cerambycidae) from southeastern Queensland, Australia


Excastra albopilosa  
Tweed, Ashman & Ślipiński, 2024


A new genus and species of Cerambycidae from the subfamily Lamiinae is described from subtropical rainforest in southeastern Queensland, Australia. Excastra albopilosa gen. et sp. nov. is easily distinguished from all other Australian Lamiinae by its dense covering of short adpressed white setae and the long erect white setae forming twisted spires. A modification to the key to Australian Lamiinae genera is provided to accommodate Excastra gen. nov.

Subfamily Lamiinae Latreille, 1825 
Tribe Ancitini Aurivillius, 1917 

Excastra Tweed, Ashman & Ślipiński, gen. nov. 

Diagnosis. Distinguished from all known Australian Lamiinae genera by the combination of the following characters: completely separated eye lobes; absence of apical carina on scape; combined length of antennal segments 3 and 4 much shorter than 5-11 combined; broad lateral tubercule on the pronotum; clavate femora; paired protibial spurs; comb-like antennal cleaner on the mesotibia; twisted spires of elongated setae concentrated around the head, pronotum, and anterior third of the elytra.

 Holotype of Excastra albopilosa Tweed, Ashman & Ślipiński, gen et. sp. nov. as it was found; resting on a Lomandra leaf in Binna Burra Lodge campground. A: dorsal. B: lateral.

  Etymology. The genus name is derived from the Latin words ex meaning “from”, and castra meaning “camp”, and is a reference to the discovery of this species within the Binna Burra Lodge campground. Gender feminine. 

Remarks. Excastra gen. nov. is placed within the tribe Ancitini based on its strong resemblance to other members of the tribe. It falls within the broad morphological limits given by Ashman et al. (2022): small, oval-bodied, clavate femora, and a relatively long scape. Should further specimens be collected, molecular analyses should be conducted to confirm the tribal placement. 


Excastra albopilosa Tweed, Ashman & Ślipiński, sp. nov. 

Diagnosis. Small sized lamiine. Easily recognised by the reddish-orange and black integument, and the dense covering of short adpressed white setae covering the head, thorax, and anterior third of the elytra, with scattered patches in the posterior two-thirds of the elytra. The prominent long erect setae scattered across the body, denser on head, pronotum and anterior third of elytra, forming paired twisted spires in these areas, are also highly distinct.

Etymology. The species epithet is derived from the Latin albus meaning “white”, and pilosa which is the feminine form of pilosus meaning “hairy”, in reference to the white hairs that cover much of this species’ body.

[Botany • 2024] Phlogacanthus sudhansusekharii (Acanthaceae) • A New Species from India


Phlogacanthus sudhansusekharii 

in Goswami et Maity, 2024.

Abstract
Phlogacanthus sudhansusekharii, a new species is described here from the state of Arunachal Pradesh, India. This newly described species is closely allied to Phlogacanthus guttatus (Wall.) Nees, but can be differentiated by its strikingly different yellowish-cream colored corolla with yellow patches and brown maculation, ratio of calyx lobes and tube length being ~1:1 and deltoid staminodes (vs. greenish-cream to white corolla with red-maroon maculation, ratio of calyx lobes and tube length ~2:1 and subulate-ensiform staminodes in the latter).

Keywords: Andrographideae, Arunachal Pradesh, Phlogacanthus sudhansusekharii

[Botany • 2024] Cattleya attenboroughiana (Orchidaceae: Laeliinae) • A New Species from the Diamantina Plateau, Minas Gerais, Brazil


Cattleya attenboroughiana E.L.F.Menezes, Giordani & R.A.Pinheiro, 

in Menezes, Giordani, Pinheiro et Gonella. 2024. 

Summary
A new species of Cattleya ser. Parviflorae (Orchidaceae) is here described from the campos rupestres of the Diamantina Plateau, part of the Espinhaço Range, Minas Gerais, SE Brazil. The new species is named Cattleya attenboroughiana and it is here compared to the most similar taxa and illustrated with photographs. The new species is likely a microendemic but the available data is insufficient for a precise conservation status assessment, so we consider it Data Deficient (DD), reinforcing the need for further exploration in the Diamantina Plateau.

Key Words: Campos rupestres, endemism, Espinhaço Range, orchid
