#NewSpeciesAlert - ๐ป๐๐๐๐ ๐๐ฆ๐๐๐๐ข๐ ๐๐ข๐๐๐๐๐๐๐, a new species of walking shark (Hemiscylliidae), is described from Milne Bay Province, eastern PNG, between the Amphlett Islands (off northern Fergusson Island, DโEntrecasteaux Islands) and the Trobriand Islands. The authors of this study address the gaps in the known distribution of walking sharks endemic to eastern Papua New Guinea, which has historically been poorly known.

Blakeway, J.-A., Townsend, K., Erdmann, M., Allen, G., Teliwa, M., Waranaka, J.-A., Brooks, W., & Dudgeon, C. L. (2026). A review of walking shark (Hemiscylliidae: ๐ป๐๐๐๐ ๐๐ฆ๐๐๐๐ข๐) distributions in Papua New Guinea and description of a new species.

Walking sharks (๐ป๐๐๐๐ ๐๐ฆ๐๐๐๐ข๐) comprise 9 morphologically similar species whose identification relies on distinctive color patterns, genetic markers, and geographically restricted distributions.
The genus is endemic to Australia and the island of New Guinea, a region that coincides with the global hotspot for carpet shark diversity (Orectolobiformes) that has been shaped by complex tectonic and seaโlevel histories. Although knowledge of walking shark distributions has been updated over the past two decades, the species endemic to eastern Papua New Guinea remain poorly known.
This study addresses these gaps by investigating the distributions of walking sharks in eastern Papua New Guinea. We used a series of in-situ surveys to review the ranges of walking shark species and to document their species-specific color patterns, complemented by an assessment of genetic markers to confirm the updated geographical distributions across species and explore phylogeographic patterns in the region.
We present updated distributions for two species (๐ป. ๐๐๐โ๐๐๐๐ and ๐ป. โ๐๐๐๐ ๐ก๐๐๐๐)ยธ as well as a theory for the development of a mosaic of disjunct, non-overlapping distributions previously unreported for the genus. Additionally, we describe a tenth member of the genus, ๐ป๐๐๐๐ ๐๐ฆ๐๐๐๐ข๐ ๐๐ข๐๐๐๐๐๐๐, n. sp., which is likely to be highly threatened.
We present possible mechanisms that may have produced this mosaic of distributions and influenced speciation in the region. Finally, we discuss the conservation implications of these findings.

๐ป๐๐๐๐ ๐๐ฆ๐๐๐๐ข๐ ๐๐ข๐๐๐๐๐๐๐ is named in honour of Christine L. Dudgeon, a renowned elasmobranch geneticist and ecologist who has researched ๐ป๐๐๐๐ ๐๐ฆ๐๐๐๐ข๐ phylogenetics and speciation for the past two decades and who first collected this undescribed species. The local common name at the type locality is kadedekedewa, which loosely translates to dog shark or lazy shark with reference to its slow, four-limbed gait. It is known as botabota at the Trobriand Islands.

"๐๐๐กโ๐๐๐๐๐๐โ๐๐ข๐ ๐๐๐๐๐, like all congeners, completes its seasonal life cycle in ephemeral freshwater wetlands, making it highly vulnerable to habitat degradation. These wetlands are increasingly threatened by human activities such as agriculture, water abstraction, urban expansion, industrial pollution, and mining.

The description of this new species from the lower Luapula River drainage aims to highlight the urgent need for stronger freshwater wetland conservation efforts by both national and international stakeholders."

๐๐๐กโ๐๐๐๐๐๐โ๐๐ข๐ ๐๐๐๐๐, new species, is described from ephemeral wetlands in the upper Lubi River system, a left bank affluent of the lower Luapula River drainage (upper Congo River drainage) in the Democratic Republic of the Congo. It is identified as belonging to the ๐. ๐๐๐๐๐๐ species group that is endemic to the upper Congo River and upper and middle Zambezi River drainages in south-central Africa. Members of this species group are characterised by a combination of colour pattern features in the male: light blue scales with broad brown-red borders creating a reticulated pattern on body; brown-red spots on proximal portion of median fins; and, caudal and anal fins with either a pattern of dark distal and light subdistal bands or, on the caudal fin an overlaying light blue iridescent distal band.
๐๐๐กโ๐๐๐๐๐๐โ๐๐ข๐ ๐๐๐๐๐ is distinguished from all other members of this species group by: (i) a unique colour pattern in the male combining median fins with an irregular red-brown reticulated pattern and an overlaying light blue iridescent distal band; an anal fin lacking a subdistal band but having, rather, a narrow red-brown margin on fin-ray tips; (ii) significant differences in morphometric and meristic characters; (iii) molecular analysis of the mitochondrial COI barcoding gene, identifying a phylogenetically distinct lineage; and (iv) unique cytogenetic characteristics showing a multiple sex chromosome system with diploid number 2n = 49 for males and 2n = 50 for females.

๐๐ฏ๐๐๐ฟ๐ฎ๐ฐ๐
A new species of bumblebee goby, ๐ต๐๐๐โ๐ฆ๐๐๐๐๐ข๐ ๐๐๐๐๐๐ sp. nov. (Teleostei, Oxudercidae), is described based on 31 specimens collected from the Hengqin Island, Guangdong Province, China.
This new species is distinguished from all other valid species of ๐ต๐๐๐โ๐ฆ๐๐๐๐๐ข๐ by its extreme small size (SL < 9 mm) and distinctive number, position, size and shape of its black bars. It possesses four complete (forming ring) or nearly complete post-cephalic, relatively narrow bars, two of which are located posterior to the base of the anal fin. The first bar behind the head extends pigmentation to the first dorsal fin but does not reach the midventral line. The second bar, chevron-shaped and located below the second dorsal fin, extends pigmentation onto that fin and ventrally reaches the midventral line and the anal fin. Cytochrome oxidase subunit I-based analyses, including six out of the eight valid species of ๐ต๐๐๐โ๐ฆ๐๐๐๐๐ข๐ , show ๐ต๐๐๐โ๐ฆ๐๐๐๐๐ข๐ ๐๐๐๐๐๐ sp. nov. to be more than 10% genetically divergent from other species, supporting the morphological diagnosis and confirming its distinct taxonomic status.
With a maximum size of less than 9 mm SL (based on observations of 106 specimens), the new species is not only the smallest species of ๐ต๐๐๐โ๐ฆ๐๐๐๐๐ข๐ , but also one of the smallest known gobioid fishes.
๐๐๐๐บ๐ผ๐น๐ผ๐ด๐
The specific epithet is in honour of Ms. Jennie Ruby Jane. The name recognises her exceptional character and achievements, which proved source of inspiration for the first author who discovered the new species. The name is used as a noun in apposition. The Chinese vernacular name proposed for this new species is โ็ๅฆฎ็ญ่พ่้ฑผโ.

๐๐ฏ๐๐๐ฟ๐ฎ๐ฐ๐
A new species of ๐ถโ๐๐๐๐๐๐๐๐ข๐ is described from tributaries of the Orinoco River in Colombia and Venezuela.
The new species can be distinguished from congeners by a combination of characters, including presence of a conspicuous blotch on the caudal peduncle, presence of secondary vertical bars in addition to primary bars, a complete lateral line with 31โ34 perforated scales, 14 circumpeduncular scales, absence of hooks on the pelvic-fin rays of mature males and absence of sexual dichromatism. Molecular species-delimitation analyses consistently supported the monophyly of ๐ถ. ๐๐๐๐๐ฃ๐๐ข๐ and recognized it as an independent lineage. Molecular divergence between this lineage and other closely related species was substantially higher than the minimal variation observed within it, providing strong evidence for its status as a distinct species.
This study highlights the often overlooked role of museum collections in harboring hidden biodiversity.

The specific name is derived from the Latin ๐๐๐๐๐ฃ๐๐ข๐ (neuter), meaning โoblivionโ or โforgetfulness.โ The name refers to the fact that this species remained undescribed for many years despite being preserved in scientific collections, thus highlighting the often overlooked role of museum collections in harbouring hidden biodiversity and the importance of revisiting historical material.
