Abstract
Recently, the tiger-cat species complex was split into Leopardus tigrinus and Leopardus guttulus, along with other proposed schemes. We performed a detailed analysis integrating ecological modeling, biogeography, and phenotype of the four originally recognized subspecies—tigrinus, oncilla, pardinoides, guttulus—and presented a new multidimensional niche depiction of the species. Species distribution models used > 1400 records from museums and photographs, all checked for species accuracy. Morphological data were obtained from institutional/personal archives. Spotting patterns were established by integrating museum and photographic/camera-trap records. Principal component analysis showed three clearly distinct groups, with the Central American specimens (oncilla) clustering entirely within those of the Andes, namely the pardinoides group of the cloud forests of the southern Central-American and Andean mountain chains (clouded tiger-cat); the tigrinus group of the savannas of the Guiana Shield and central/northeastern Brazil (savanna tiger-cat); and the guttulus group in the lowland forests of the Atlantic Forest domain (Atlantic Forest tiger-cat). This scheme is supported by recent genetic analyses. All species displayed different spotting patterns, with some significant differences in body measurements/proportions. The new distribution presented alarming reductions from the historic range of − 50.4% to − 68.2%. This multidimensional approach revealed a new species of the elusive and threatened tiger-cat complex.

[Botany • 2024] Indigofera abbottii, I. ngwenyana, etc. (Fabaceae: Papilionoideae: Indigofereae) • New and poorly known Taxa of Indigofera from the Pondoland Centre of Endemism, South Africa: Part 2


Indigofera abbottii Schrire & K.W.Grieve,

in K. W. Grieve, G. R.H. Grieve et Schrire, 2024.

 Highlights: 
• Taxonomic description of new and little known Indigofera species from South Africa.
• Four new Indigofera species, one new variety and two little known species are described.
• One established taxon is raised to specific status and described with a new name.
• An earlier name is found which has priority over an established species name.
• All taxa are associated with the Pondoland Centre of Endemism, ranging to surrounding floristic areas.

Abstract
This second paper describes and clarifies new and poorly known Indigofera species, belonging to sect. Pinnatae (E.Mey.) Harv., from the Pondoland Centre of Endemism and associated neighbouring areas in the Eastern Cape and KwaZulu-Natal provinces, South Africa. Five new species (one with two infraspecific taxa) are recognized: Indigofera abbottii Schrire and K.W.Grieve, I. hillburttii Schrire and K.W.Grieve, I. tysonii Schrire and K.W.Grieve, I. herrstreyi Schrire and K.W.Grieve var. herrstreyi and I. herrstreyi var. helodes K.W.Grieve and Schrire, and I. ngwenyana Schrire and K.W.Grieve. Descriptions are provided for the poorly known I. corniculata E.Mey. and I. gerrardiana Harv., taxa rarely taken up in the literature and both having been mostly synonymised under I. dregeana E.Mey. that occurs outside the area of the present study. The name I. tenuissima E.Mey. was found to be the earliest, correct, name for the widespread species I. longipes N.E.Br. ex Baker f., leaving the coastal Zululand taxon – currently named I. tenuissima E.Mey. – requiring further evaluation.

[Ornithology • 2023] Catharus arcanus, C. fuscater, C. mirabilis, etc. • Integrative Taxonomy reveals Hidden Diversity in the Catharus fuscater (Passeriformes: Turdidae) complex in Central and South America


 Darién Nightingale-thrush Catharus arcanus
 Halley, Catanach, Klicka & Weckstein, 2023
 

Abstract
We assembled datasets of genetic (genomic ultraconserved elements [UCEs], mtDNA) and phenotypic (morphology, voice) characters to address species limits and taxonomy in the slaty-backed nightingale-thrush Catharus fuscater (Passeriformes: Turdidae), a polytypic complex of songbirds with a broad montane distribution in Central and South America. We identified 10 allopatric populations that have been evolving independently for multiple glacial cycles. Genetic structure is broadly correlated with divergence in phenotypic characters, including plumage colour, iris colour, maxilla (bill) colour, and the acoustic structure of vocalizations (calls and songs). We propose an integrative taxonomic revision that recognizes seven species in the complex, including a newly described species from eastern Panama, and four subspecies, of which two are newly described.

[Herpetology • 2024] Pareas guanyinshanensis • A New Species of the Pareas hamptoni Complex (Serpentes: Pareidae) from Yunnan, China, with Confirmation of P. hamptoni sensu stricto in China


 Pareas guanyinshanensis

Liu, Mo, M. Li, B. Li, Luo, Rao & S. Li, 2024.

Abstract
We describe a new species of the genus Pareas, based on three specimens collected from Guanyinshan Provincial Nature Reserve in Yuanyang County, Honghe Prefecture, Yunnan Province, China. The new species is distinguished from its congeners by one preocular, one postocular or postocular fused with subocular, loreal not bordering the orbit, one row enlarged vertebral scales, five rows keeled mid-dorsal scales at the middle of the body, 189–192 ventral scales and 72–89 subcaudal scales. The dorsal surfaces of the head and body are yellowish red or yellowish brown, and the belly and ventral surfaces of the head and tail are pinkish yellow or yellow with more or less small black spots. Phylogenetic analyses of mitochondrial DNA recovered the new species being the sister taxon to P. hamptoni sensu stricto. The genetic divergences between the new species and P. hamptoni sensu stricto were 4.2% in the Cyt b sequences and 5.0% in the ND4 sequences. In addition, based on specimens collected from Honghe and Wenshan prefectures, we confirmed that P. hamptoni sensu stricto is distributed in China.

Simple Summary: In this paper, a new Pareas species of the P. hamptoni complex is described from southern Yunnan Province, China, based on morphological and molecular evidence. Genetically, the new species is most closely related to P. hamptoni sensu stricto, for which we confirm the distribution in China. Morphologically, the new species can be distinguished from P. hamptoni sensu stricto and all other congeners by a combination of morphological characteristics. The discovery of the new species brings the total number of recognized species of the genus Pareas to 31, of which 25 occur in China.

[Crustacea • 2024] Booralana nickorum • A New Species of Deep-sea Booralana Bruce, 1986 (Isopoda: Cirolanidae) from The Bahamas, Western North Atlantic


Booralana nickorum
in Shipley, Bruce, Higgs, Rawlins, Irschick, Gutierrez, ... et Brooks, 2024. 

 
Abstract
Booralana nickorum sp. nov. is described from the deep-water slope of the Exuma Sound, The Bahamas, from depths of 540 to 560 metres. It is the fourth species to be assigned to the genus and the second species described from the Western North Atlantic. The species can be distinguished from Booralana tricarinata Camp and Heard, 1988 and the other species by the sub-triangular pleotelson and the uropodal exopod of mature males being far longer than endopod, with both rami extending well beyond the posterior margin of the pleotelson. Additionally, pleopods 3 and 4 lack a prominent angle at midpoint of ramus.

[Entomology • 2024] Lasioglossum iridescens, L. dilisena & L. silveirai • A Problematic Species Complex of Lasioglossum Subgeneric Diagnostics in North America (Hymenoptera: Halictidae)


Lasioglossum (Sphecodogastra) dilisena
 Hettiarachchi & Gibbs, 2024

 
Abstract
A problematic species complex within Lasioglossum subgenus Sphecodogastra with unusual metallic reflections on the mesosoma is described from North America. Three new species in this complex are described and illustrated: Lasioglossum (Sphecodogastra) iridescens sp. nov., Lasioglossum (Sphecodogastra) dilisena sp. nov., and Lasioglossum (Sphecodogastra) silveirai sp. nov. Our study addresses the challenge of diagnosing Lasioglossum subgenera within North America. We present an updated key for the North American Lasioglossum subgenera.

Key words: Apoidea, classification, cryptic species, new species, taxonomy


Lasioglossum (Sphecodogastra) iridescens sp. nov. 

Etymology. The specific epithet refers to the iridescent colouration of the new species.


Lasioglossum (Sphecodogastra) dilisena sp. nov. , ♀, holotype.
A. Dorsal habitus. b. Face. C. Lateral habitus. D.Metasoma.
Scale bars = 1 mm.

Lasioglossum (Sphecodogastra) dilisena sp. nov. 

Etymology. The specific epithet ‘dilisena’ is derived from the Sinhala word ‘dilisena’ දිලිසෙන, which means ‘shining’, but is used here as a noun in apposition. This name was chosen because all three species described in this paper have an unusual metallic reflection on the mesosoma that is not seen in other known North American species in the subgenus Sphecodogastra. The first author is also a native speaker of Sinhala from Sri Lanka. Sinhala language is one of the official and national languages of Sri Lanka and the mother tongue of the majority people of Sri Lanka. Through this naming choice, we hope to honour all the linguistic and cultural diversity of the world.

 
Lasioglossum (Sphecodogastra) silveirai sp. nov., ♀, holotype.
A. Dorsal habitus. b. Face. C. Lateral habitus. D. Metasoma.

Abstract
Extant cicada (Hemiptera: Cicadoidea) includes widely distributed Cicadidae and relictual Tettigarctidae, with fossils ascribed to these two groups based on several distinct, minimally varying morphological differences that define their extant counterparts. However, directly assigning Mesozoic fossils to modern taxa may overlook the role of unique and transitional features provided by fossils in tracking their early evolutionary paths. Here, based on adult and nymphal fossils from mid-Cretaceous Kachin amber of Myanmar, we explore the phylogenetic relationships and morphological disparities of fossil and extant cicadoids. Our results suggest that Cicadidae and Tettigarctidae might have diverged at or by the Middle Jurassic, with morphological evolution possibly shaped by host plant changes. The discovery of tymbal structures and anatomical analysis of adult fossils indicate that mid-Cretaceous cicadas were silent as modern Tettigarctidae or could have produced faint tymbal-related sounds. The discovery of final-instar nymphal and exuviae cicadoid fossils with fossorial forelegs and piercing-sucking mouthparts indicates that they had most likely adopted a subterranean lifestyle by the mid-Cretaceous, occupying the ecological niche of underground feeding on root. Our study traces the morphological, behavioral, and ecological evolution of Cicadoidea from the Mesozoic, emphasizing their adaptive traits and interactions with their living environments.
