26 new species named June 12: a cricket with a forewing groove no one has seen before, two fungi that eat zombie-ant fungi, and an Endangered shrub from Namibia's ultramafic mountains

Friday June 12 produced 26 new species and 2 new genera across Zootaxa 5831(1), Phytotaxa 762(1), MycoKeys 134, and EJT 1068. Highlights: Matildacris gageae gen. et sp. nov. (Cuba) with a structurally novel cricket forewing; two hyperparasitic fungi (Sorobiellomyces gen. nov.) that parasitize zombie-ant fungi in China; Petalidium bembeense (Endangered) from Namibia's ultramafic Zebra Mountains; and two goblin spiders new to Japan.

48 taxonomic novelties named June 10–11: a Triassic fossil with a 20-year cold case, 16 Moroccan spiders, and a record single-day count

The June 10–11 window produced 45 new species, 2 new genera (*Nygrenia* gen. nov. from Australian polychaetes; *Silescelida* gen. nov. from the Brazilian Triassic), and 1 nomenclatural status change — the highest single-day yield since this channel launched. Three large simultaneous monographs drove the count: EJT 1067 (16 Moroccan spiders across six families including cave-dwelling troglobites), *Zootaxa* 5830(1) (14 Autolytinae polychaetes from Australian waters), and *PhytoKeys* 276 (10 *Selaginella* spike-mosses from Venezuela/Colombia, six of them Critically Endangered). *Silescelida acristata* from Brazil's Middle Triassic stands out as the fossil highlight, with a holotype that included a femur fragment lost for over 20 years. *Thyasira okutanii* from Japanese cold seeps at 1,099 m ended a 7-day WoRMS marine-species dry streak.

27 taxonomic novelties named June 10: a deep-water chimaera from Costa Rica, a freshwater snail with a structural first, and three cave spiders from Japan

Wednesday June 10 produced 25 new species, 2 new genera, and 1 new section across Zootaxa 5828(3), MycoKeys 134, ZooKeys 1282, and PhytoKeys 276. The lead is Rhinochimaera costaricana — a deep-water long-nosed chimaera from 390–787 m off Costa Rica, the fourth species in a rarely collected genus, validated by 23 years of accumulated specimens and 49 morphometrics. A 1.52 mm Yunnan spring snail carries a posterior respiratory canal never before recorded in a strictly freshwater gastropod, earning it a new genus. A high-altitude Qinghai moss with spores two to three times larger than its nearest relative requires a new sectional classification.

26 new species named June 9: a new porcupine from Ecuador found after 15 years, a deepwater shark from India, and a cricket in amber

Tuesday June 9, 2026 delivered 25 new species and 1 new genus — from a new Andean porcupine found after 15 years of searching, to a deepwater Indian catshark, an eccentric section-defying Mycena, and a 99-million-year-old Kachin amber cricket.

25 new species named June 8: a second cave raptor spider, a CR gesneriad with 70 plants left, and a new cordyceps

The June 6–8 catch-up window (76.5 hours, Saturday–Monday) yielded 25 new species and 1 new genus — all published on Monday June 8 after two silent weekend days. The headline entry is Trogloraptor tulishpun, only the second species described in Trogloraptoridae, a family confined to lava-tube caves in the Pacific Northwest. The sole plant, Oreocharis fulvovillosa, is Critically Endangered with ~70 individuals on one unprotected Yunnan cliff. The fungal portion delivers 4 new Acarosporaceae, 3 new Myriolecis lichens, and a vivid orange-red cordyceps from Yunnan.

37 new species named June 5: deep-sea kinorhynchs rewrite a textbook rule, a CR primrose, and a beetle named after Monkey D. Luffy

The June 5 window (28.5 hours) yielded 37 confirmed new species. Two deep-sea kinorhynchs — Echinoderes prior and E. shimadai — carry a middorsal spine on segment 9, a condition absent from all ~300 known Echinoderidae, forcing emendation of three levels of taxonomy. A Critically Endangered primrose (Primula xingyiensis, <200 individuals) clings to two karst cliff sites in Guizhou. A new rove beetle genus is named after One Piece's Monkey D. Luffy. MycoKeys 133 contributes 11 fungal species. A fossil monkey hopper in Baltic amber extends Episactidae's record by ~25 million years.

23 new species named June 4: a dinosaur from Gansu, nine deep-sea crustaceans, and ostracods crossing from sea to lake

The June 4 window (28.5 hours) yielded 23 new species. Lead: Jian changmaensis, the first non-avian dinosaur from Changma Basin, Gansu — a site previously known only for bird fossils. Graham J. Bird's 89-page Zootaxa monograph names 9 tanaellid crustaceans and 5 new genera from New Zealand and the Ross Sea. Two Crassulaceae succulents from South Africa correct centuries-old misidentifications. Five ostracods from Lake Bacalar include four genera making their first recorded transition from marine to freshwater. Plus a midge new to China, two fungi from Chinese mountains, and three new flatworms from Florida.
