11 species named this week: a two-call glassfrog, Idaho's hidden spider, and four fungi (2026)

The week's names include a glassfrog whose advertisement repertoire has two call types, a spider that moves the known range of its genus about 500 kilometres east, and a bacterium isolated from maize-root soil. This representative selection covers 11 species in dated primary papers published from August 28 through September 3, 2026. A registry-wide weekly export from WoRMS, GBIF, and Zoological Record was unavailable, so the selection follows publisher-native taxonomic papers rather than claiming a worldwide total.

Forest, stream and estuary animals

Hexura vandal — an Idaho funnel-web spider

Taxonomy: Arthropoda → Arachnida → Araneae → Antrodiaetidae → Hexura. The species belongs to the mygalomorph spiders, a group that includes trapdoor and funnel-web builders. 1
Locality and habitat: The type locality is near Apgar Campgrounds, Lowell, Idaho, in the Rocky Mountains. The spiders occupy mesic conifer forest, making silken funnel webs under or inside logs and in moss mats. 1
Describers and institutions: Arnau Calatayud-Mascarell, Ethan J. Briggs, and Chris A. Hamilton described the species. Their affiliations include the University of Idaho and the Australian Museum Research Institute. 1
Distinguishing features: Morphological, molecular, and geographic evidence separates H. vandal from the two other described species. The Idaho lineage extends the known distribution of Hexura by about 500 kilometres from the Coastal Ranges and western Cascades of Oregon and Washington. 1
Threat status: No formal IUCN assessment is reported. The paper describes the known range as extremely restricted and discusses logging, wildfire pressure, repeated searches, and the need for conservation action. 1

Vitreorana micaelae — a Cerrado glassfrog

Taxonomy: Chordata → Amphibia → Anura → Centrolenidae → Vitreorana. The paper gives no common name beyond the English term "glassfrog" used for the group. 2
Locality and habitat: The type locality is Luziânia, Goiás, Brazil: gallery forest beside a small stream near the São Bartolomeu River, at 826 metres. Gallery forest is a strip of woodland following a watercourse through a more open landscape. 2
Describers and institutions: Wilian Vaz-Silva, Sheila Pereira de Andrade, Cezar Filho Rocha, Edmar Pereira Victor Jr., Reuber Albuquerque Brandão, and Natan Medeiros Maciel described the species. Their affiliations include Pontifícia Universidade Católica de Goiás, Universidade Federal de Goiás, Centro Tecnológico de Engenharia, and Universidade de Brasília. 2
Distinguishing features: Adult males measure 21.7–26.1 millimetres from snout to vent. The frog has a rounded snout in dorsal view, a sloping profile, small enamel-like cloacal tubercles, and white iridophores over the pericardium, liver, and urinary bladder while most other visceral peritonea remain transparent. Its advertisement repertoire has a short call and a long call, with dominant frequencies around 4.65–4.76 kilohertz. 2
Threat status: No formal IUCN assessment is reported. The paper identifies V. micaelae as the second known glassfrog endemic to the Cerrado. 2

Ilyoplax kagga — a mangrove mudflat crab

Taxonomy: Arthropoda → Malacostraca → Decapoda → Dotillidae → Ilyoplax. 3
Locality and habitat: The crab lives in upper mudflats among mangroves, soft mud, and oyster beds at the Aghanashini River Estuary in Karnataka, on India's west coast. The estuary is a Ramsar site, and the paper records crabs feeding among the pneumatophores of Rhizophora mangroves. 3
Describers and institutions: Mani Prema, Vithal S. Kakati, and Peter K. L. Ng described the species. The authors are affiliated with the Lee Kong Chian Natural History Museum at the National University of Singapore, the Centre for Marine Living Resources and Ecology, the Centre of Advanced Study in Marine Biology at Annamalai University, and the Central Marine Fisheries Research Institute. 3
Distinguishing features: The rectangular, smooth carapace carries a stridulatory ridge with 22–24 subconical tubercles and 5–7 fungiform tubercles on its inner half. Males usually have unequal massive claws, and males have dense setae on the carpus and propodus of the second and third walking legs. 3
Threat status: No formal IUCN or equivalent assessment is reported. The name kagga honours an endemic, salt-tolerant rice variety cultivated traditionally at the type locality. 3

Insects with anatomical identification keys

Gryllotalpa xinjiangica — the Xinjiang mole cricket

Taxonomy: Arthropoda → Insecta → Orthoptera → Gryllotalpidae → Gryllotalpa. The English common name above is a direct rendering of the Chinese name supplied by the paper. 4

A bacterium at the maize root–soil boundary

Dyella cornirhiza

Taxonomy: Proteobacteria → Gammaproteobacteria → Burkholderiales → Rhodanobacteraceae → Dyella. No common name is given. 7
Locality and substrate: The type strain, CR191T, came from maize rhizosphere soil in Sanya City, Hainan Province, China, at 18°23′24″ N, 109°09′32″ E. Rhizosphere soil is the soil that remains tightly attached to a plant root after loose soil has been removed. 7
Describers and institutions: Ying Li, Lei Shen, Miaomiao An, Xuming Wang, Guozhu Zhao, and Tianlei Qiu described the species. Their affiliations include Beijing Forestry University, Beijing Academy of Agriculture and Forestry Sciences, and Langfang Normal University. 7
Distinguishing features: CR191T consists of aerobic, Gram-negative, non-motile rods measuring 0.4–0.6 × 1.5–2.5 micrometres. It forms smooth, yellow, opaque colonies about 1–1.5 millimetres across after five days at 30 °C. The strain's 16S similarity to close relatives is 98.15–98.23%, while ANI values are 79.0–86.6% and dDDH values are 20.2–28.7%, supporting species-level separation. The genome contains six putative secondary-metabolite biosynthetic gene clusters; the paper says the corresponding metabolites have not yet been experimentally verified. 7
Threat status: No formal extinction-risk assessment is reported. 7

The eleven species occupy places that are easy to miss in a broad survey: moss around a log, gallery forest beside a stream, mangrove pneumatophores, a mole cricket's digging soil, mountain leaves, rotten wood, and the thin soil layer touching a maize root. Their names become possible through equally small evidence: a call with two forms, a ridge of fungiform tubercles, a male genital structure, a spore's shape and dimensions, or genome-wide distances. The papers report no formal extinction-risk assessment for any of these eleven species. That blank records the current state of assessment; the restricted localities of H. vandal and V. micaelae, and the habitat specificity of the others, remain field facts that future surveys can test and conservation work can use.
