Highly localised morphological diversity in the mayfly Cloeon tasmaniae Tillyard (Ephemeroptera; Baetidae), and a new synonomy with C. paradieniense Suter

open access: yesAustral Entomology, Volume 65, Issue 1, February 2026.
Abstract Ambiguity over the features that differentiate two nominal species of baetid mayflies, Cloeon paradieniense Suter and C. tasmaniae Tillyard, in southeast Australia led to a detailed analysis of the morphology and meristics of specimens from Victoria, South Australia and, in particular, Tasmania, where both species have been reported.

Saprolegnia parasitica S1 and S2 Strains Differ in Zoospore Transition Timing and Pathogenicity Against Juvenile Atlantic Salmon (Salmo salar)

open access: yesJournal of Fish Diseases, Volume 49, Issue 2, February 2026.
ABSTRACT S1 and S2 strains of S. parasitica are both common among diseased farmed salmonids in Nova Scotia, whereas globally S1 is rare and S2 is common. Following the initiation of asexual maturation and overnight incubation at 20°C then harvest, and incubation at 10°C in vitro, S2 secondary zoospores mostly transformed into cysts within 3 h, and by 6
