[PaleoIchthyology • 2026] Talentichthys kuragh • A new Devonian lungfish (Dipnoi: Holodontidae) from the western Karakoram of northern Pakistan


Talentichthys kuragh 
Young & Lu, 2026


Abstract
A well-preserved sarcopterygian fish skull from the Famennian (Upper Devonian) Shogrãm Formation, of the Chitral region, northern Pakistan, is described. Collected as a calcareous nodule by J.A. Talent and colleagues, it has been investigated using high-resolution computed tomography to reveal the internal cranial architecture. It represents a new genus and species of tooth-plated, cosmine-covered dipnoan (lungfish), Talentichthys kuragh n. gen. n. sp., distinguished from all previously described Devonian dipnoans by its deep nasal notches, elongate narrow subnasal ridge, and uniquely shaped olfactory cavities. Additional specimens from the type locality, showing additional aspects of morphology, will be necessary to clarify the phylogenetic position of the new form within the Dipnoi.

Keywords: Devonian lungfish; Dipnoi; Talentichthys; Famennian; northern Pakistan

ANU V3736, holotype of Talentichthys kuragh n. gen. n. sp., the anterior portion of a lungfish skull preserved in calcareous matrix.

Systematic palaeontology
Class Osteichthyes Huxley, 1880
Subclass Sarcopterygii Romer, 1955

Superdivision Dipnomorpha Ahlberg, 1991
Division Dipnoi Müller, 1845
Family Holodontidae Gorizdro-Kulczyzka, 1950

Genus Talentichthys n. gen.

Etymology: The generic name commemorates Professor John Talent, with -ichthys (Gk) for fish.
 
Diagnosis: A tooth-plated, cosmine-covered dipnoan with deep notches for the anterior (incurrent) nares, elongate subnasal ridges, and the nasal cavity subdivided dorsally into a posteromesial reniform recess, and an anterolateral subdivision elongated rostrocaudally that extends as a groove to the nasal notch.

Remarks: The new taxon is represented by only one incomplete anterior skull portion, which displays nasal notches in the upper mouth margin, a long and deep nasal groove, prominent subnasal ridge and a pterygoid tooth plate. These features demonstrate dipnoan affinity, and are not consistent with porolepiforms, the other major dipnomorph subgroup, in which cosmine-covered forms are predominantly of Early Devonian age. We provisionally refer Talentichthys n. gen. to the family Holodontidae, based on the updated diagnosis and comprehensive review of the family provided by Long (2010). Although very incomplete, our new taxon displays features not shown in any previously described dipnoan. Further material from the Karakoram type area (currently inaccessible) will clarify the relationships of the new taxon.

Talentichthys kuragh n. gen. n. sp.

Etymology: The specific epithet is the local term ‘Kurãgh’ from the name of the stratigraphic section of Talent et al. (1999) which produced the specimen.
 
Locality and horizon: Collected from about 63 m above the base of the Kurãgh Spur stratigraphic section of Talent et al. (1999), about 55 km northeast of Chitral, northern Pakistan (Fig. 1), within the Upper Devonian (Famennian) Shogrãm Formation.

Holotype: ANU V3736, the only known specimen (ANU Department of Materials Physics, Research School of Physics, Canberra).

[PaleoMammalogy • 2026] Metapterodon anari • Hyaenodonta from the Middle to Late Miocene deposits of the Siwaliks of Pakistan with a brief account of Indian subcontinent hyaenodonts

Abstract
New fossil material identified as ‘creodonts,’ particularly hyaenodonts, from the Siwaliks of Pakistan provide significant new information on this important group of carnivores. Three hyaenodont taxa are identified based on these new fossils. Deciduous dental remains identified as ?Megistotherium/Hyainailouros sp. provide important new data on large hyaenodonts and their presence in the Miocene of southern Asia. Fossils identified as Hyaenodon cf. H. pervagus potentially provide important new temporal and biogeographic data on a highly speciose genus of hyaenodont. While the genus is known throughout much of the Northern Hemisphere (Asia, Europe, North America), these new fossils represent the first record of the genus from the Siwaliks, expanding its range in southern Asia. They also represent the youngest temporal occurrence of the genus (Middle Miocene). Another fossil represents a new species, Metapterodon anari sp. nov. This genus was previously tentatively identified from the Siwaliks, but this new material provides definitive evidence of its presence. Not only does this confirm its presence in the Miocene Siwalik deposits of the Indian subcontinent but also represents an important temporal occurrence for the genus. It represents the youngest occurrence of the genus worldwide but may also represent the youngest occurrence of any hyaenodont. The new material provides important new data on some of the less well-known ‘creodonts’ of the Siwaliks, and this data is important for not only our understanding of some of the youngest hyaenodonts near their eventual extinction, but the complex mammal communities preserved on the Indian subcontinent.

[Fungi • 2026] Leucocoprinus roseus (Basidiomycota: Agaricaceae) • Molecular Phylogenetic and Morphological Analyses revealed A New Species from Punjab, Pakistan


Leucocoprinus roseus W. Akram, Saba & Asif,  

in Akram, Saba, Asif, Nawaz, F. Ullah, Samen, Maula et M. Ullah, 2026. 
 
Abstract
In this article, we describe a new fungal species, Leucocoprinus roseus, collected in Canal View Park, District Mandi Bahauddin, Punjab, Pakistan. The species is proposed as new based on detailed morphological observations and molecular phylogenetic analysis using nuclear ribosomal DNA internal transcribed spacer (nrITS) sequences. In a phylogenetic reconstruction, L. roseus forms a distinct clade clearly separated from related taxa. It is characterized by small basidiomata, a plano-convex pileus with dark red center becoming pale reddish toward the margins, center covered with squarrose scales, broadly ellipsoid amygdaliform basidiospores and versiform cheilocystidia. A comprehensive description, illustrations, and results of the phylogenetic analysis are provided, along with a comparison with morphologically and genetically related species.

[Cnidaria • 2025] Physalia mikazuki (Hydrozoa: Siphonophorae) blown into Japan’s northeast (Tohoku) at the whim of Marine Ecosystem Change


 Physalia mikazuki Yongstar, Ochiai & Lewis Ames, 
collected from Gamo Beach, Sendai City, Miyagi Prefecture, Japan.  

in Yongstar, Ochiai, Nugraha, Tan, Totsu, Sato-Okoshi et Lewis Ames. 2025. 

The discovery of Physalia mikazuki sp. nov. from the temperate waters of Gamo Beach, Sendai Bay (Miyagi Prefecture) in the Tohoku (northeast) region of Japan, represents a significant addition to the taxonomic and ecological understanding of this genus. Morphological analysis reveals key diagnostic traits, distinguishing it from all known Physalia species. Phylogenetic analyses of the 16S rRNA gene and COI (cytochrome c oxidase subunit 1) regions further confirm its classification as a distinct species, forming a well-supported monophyletic clade separate from other Physalia species. Oceanographic data and Lagrangian particle trajectory simulations suggest that P. mikazuki may have dispersed northward via the recent 100 km northward extension of the Kuroshio Current (KE) in tandem with record-breaking sea surface temperature changes (SST) of more than 2°C in the Tohoku region between 2022 and 2024. Long-term monitoring confirmed no previous reports of Physalia at the type locality of Gamo Beach, Sendai City (Tohoku) prior to 2023, indicating a likely recent introduction. Molecular barcode sequences matching samples from both Pakistan and Mexico indicate a broad Indo-Pacific connectivity for the new species. The occurrence of P. mikazuki sp. nov. in the Tohoku region poses potential ecological and public health concerns, particularly due to its predation on fish larvae and risk of envenomation during beach recreation. This study underscores the importance of integrative experimental design combining taxonomy, molecular data, and oceanographic modeling to understand species range shifts and cryptic diversity in a changing ocean.

[Botany • 2022] Allium sulaimanicum (Amaryllidaceae) • A new Allium species and section from Pakistan

 

Allium sulaimanicum N. Khan, A. Sultan et N. Friesen, 

in N. Khan, Friesen, Sultan, Fritsch, T. Khan et Ishaq, 2022.

A new species, Allium sulaimanicum, is described from northern Balochistan and southern Khyber Pakhtunkhwa in Pakistan based on morphological, molecular, and cytological studies. The new species is characterised by long runner-like cylindrical rhizomes of adult plants, cylindrical bulbs, linear leaves with minute soft hairs along veins, campanulate perigonium, and white to creamy white, ovate to elliptical, 4.5–5-mm-long acute tepals, with brownish to purplish nerves, stamens as long as to slightly longer than tepals, yellow to brick red anthers, hexagonal ovary, and white and papillate/warty along angles. The presence of long herbaceous rhizomes indicated serious isolation of the new species; hence, a new section Sulaimanicum is proposed to accommodate the new species. The new species is diploid with a chromosome number of 2n = 16. Detailed morphological description, illustrations, phylogenetic analyses based on sequences of plastid spacers (rpl32-trnL (UAG) and trnQ-rps16) and nuclear ITS, karyotype features, and a distribution map of the new species are provided.

[Fungi • 2023] Mallocybe pakistanica & M. pinicola (Agaricales: Inocybaceae) • New Species of Mallocybe from Pakistan, based on Morphological and Molecular Evidence


A Mallocybe pakistanica & B M. pinicola Saba & Khalid,

in Saba, Khalid et Sarwar, 2023. 
 Scale bars: 10 mm 

Abstract
Within the family Inocybaceae, many species of Mallocybe have been reported, but there are only a few reports of this genus from Pakistan. In this study, six collections of Mallocybe were studied by morphological and phylogenetic methods. Phylogenetic analyses, based on sequence data from two different loci (ITS and LSU) using Maximum Likelihood and Maximum Parsimony methods, have been performed to infer species relationships within Mallocybe. Results indicated that these six collections encompass two new species of Mallocybe i.e. M. pakistanica and M. pinicola, from Pakistan. Their detailed morphological descriptions and illustrations are also provided. In addition, comparison with morphologically closely-related taxa is also discussed. Previously, only two species of this genus have been recorded from Pakistan and, with this addition, the total number of reported taxa of Mallocybe has been raised to four from Pakistan. A key to the described taxa of Mallocybe from Pakistan is also provided.

Key words: Asia, molecular systematics, phylogeny, Pinaceae

Holotypes A Mallocybe pakistanica (MSM#0061) B Mallocybe pinicola (MSM#0060).
 Scale bars: 10 mm (A, B).

 Mallocybe pakistanica Saba & Khalid, sp. nov.
 
Diagnosis: Most similar to Mallocybe myriadophylla described from north-western Europe, but differs by the absence of a crowded lamellae, different pileal colouration and somewhat larger basidiospores. Phylogenetically separated from other species of Mallocybe due to unique ITS and LSU sequences.

Etymology: Referring to the country where it was discovered.


 Mallocybe pinicola Saba & Khalid, sp. nov.
 
Diagnosis: Most similar to M. siciliana and M. subtomentosa, but differs by the combination of pileal colour, absence of umbo, size of basidiospores, pyriform to broadly clavate, catenate cheilocystidia and an ecological association with Pines. Phylogenetically separated from other species of Mallocybe due to unique ITS and LSU sequences.

Etymology: Referring to its exclusive association with Pinus.

[Botany • 2023] Atriplex pseudotatarica (Amaranthaceae) • A New Species from the Indian Subcontinent

 

Atriplex pseudotatarica Sukhor. & Nidhan Singh,

in Sukhorukov, Singh, Kushunina, Zaika et Sennikov, 2023. 

Abstract
A new subshrubby C4-species from the lowlands and foothills of India, Pakistan and SE Afghanistan, Atriplex pseudotatarica, is described and illustrated. Previously, it was incorrectly identified as A. crassifolia auct. non C.A.Mey. belonging to a distant C3-group of the genus. A phylogenetic analysis based on nrITS and nrETS revealed its position as sister to A. schugnanica (sect. Obionopsis). Both species share aphyllous inflorescence and smooth bract-like cover, but differ in life form, leaves, seed colour, and geographical distribution. We revised native Indian Atriplex species and excluded some of them from the flora of the country. An improved checklist of the native Atriplex species in India with their corrected synonymy and nomenclature is given, and a new diagnostic key is provided.

Abstract
Lepiota sindhudeltana sp. nov. was found on sandy soil under Saccharum bengalense during fungal surveys to the deltas of the Indus River and the banks of the River Ravi, Punjab, Pakistan. The new species belongs to section Ovisporae, subsection Felininae and is characterized by dull orange appressed squamules on the pileus, thin pileal context, pale yellow lamellae, a stipe rounded to slightly oblong at base, basidiospores broadly ellipsoid to oblong, neither dextrinoid nor amyloid, short, clavate erect pileal hyphae, and narrowly clavate terminal hyphae of the stipitipellis. The closest described species to the new taxon in the phylogenetic tree, based on analysis of ITS and LSU sequences, is L. angusticystidiata. We present the new species with illustrated morphological description, phylogeny, and comparison with related or similar species.

[Herpetology • 2022] Eremias killasaifullahi & E. rafiqi • Appearances Often Deceive in Racerunners: Integrative Approach reveals Two New Species of Eremias (Squamata: Lacertidae) from Pakistan


 Eremias killasaifullahi & E. rafiqi 
Masroor, Khan, Nadeem, Amir, Khisroon & Jablonski, 2022


Abstract
Based on newly provided morphological and previously published genetic data, we describe two new distinctive sympatric lacertid lizards of the genus Eremias (subgenus Aspidorhinus) from the arid mountains of northwestern Balochistan Province, Pakistan. The new species, Eremias killasaifullahi sp. nov. and Eremias rafiqi sp. nov. are distinguished from all other species of the subgenus Aspidorhinus (E. afghanistanica, E. fahimii, E. isfahanica, E. kopetdaghica, E. lalezharica, E. montana, E. nikolskii, E. papenfussi, E. persica, E. regeli, E. roborowskii, E. strauchi, E. suphani, and E. velox) by unique morphological characters and genetic differentiation. In the molecular phylogeny of Aspidorhinus, both new taxa are well-supported lineages differentiated from other species of this subgenus by uncorrected p distances from 8.5% to 21.6%, respectively. Both new species belong to E. persica complex where E. rafiqi sp. nov. is partly similar in dorsal color pattern to E. persica but can be distinguished from this species by unique meristic and morphometric characters. Eremias rafiqi sp. nov. is found in Pakistan, Afghanistan, and eastern Iran. Eremias killasaifullahi sp. nov. can be differentiated from E. persica by its distant distribution, dorsal color and pattern, smaller size, and less number of gulars and ventral scales. Eremias killasaifullahi sp. nov. is only known from the type locality and represents the local microendemism, along with other endemic species of reptiles reported from this part of Pakistan. We, however, expect that E. killasaifullahi sp. nov. could have a broader range in northwestern Pakistan and southeastern Afghanistan, which should be an object of following investigations. Our data show that remote areas between Hindu Kush Mountains and Indus River need attention as they most probably represent possible sources of genetic and species diversity in the region.
