Allogynaspis flechtmanni n. gen., n. sp. is described from litter bordering a stream in a forested area of Itatiaia National Park in southeastern Brazil. Although it shares a number of traits with the free-living macrochelid genera Nothrholaspis and Macrholaspis, the new species presents a unique combination of characters that argues...
The relationships of the unusual salticid spider Depreissia from central Africa and Borneo have been difficult to resolve, obscured by its highly modified ant-like body. Phylogenetic analysis of the gene 28S strongly supports its placement outside the major clade Salticinae and within the clade of cocalodines, spartaeines and lapsiines, with...
Ceratonova shasta is a myxozoan fish parasite that impacts hatchery and wild populations of salmon and trout in the Pacific Northwest. Levels of the parasite in river water can be effectively monitored through direct filtration of parasite spores from water, extraction of total "environmental DNA" (eDNA), then quantitative polymerase chain...
A new genus and species of megaridid, Minysporops dominicanus gen. n., sp. n. (Hemiptera: Megarididae), is described from Dominican amber. Diagnostic characters include: Minute (under 2.00 mm), glabrous, nearly round body; declivitous flat-topped head; eyes constricted near middle, with dorsal eye shields; ocelli ovoid-elliptical; antennae 4-segmented, setose; rostrum 4- segmented;...

Through application of carbon (C) and nitrogen (N) stable isotope analyses, we investigated the benthic trophic structure of
the upper-slope off southern Chile (~45°S) including a recent methane seep area discovered as part of this study. The observed
fauna comprised 53 invertebrates and seven fish taxa, including remains of chemosymbiotic...
A new genus and species of chrysomeline, Stenaspidiotus microptilus, n. gen., n. sp., (Coleoptera: Chrysomelidae: Chrysomelinae) is described from Dominican amber. Diagnostic characters include an elongate, flattened body; small eyes; a narrow, long pronotum with a width/length ratio of 1.6, an irregular pronotal surface with marginated lateral edges, distinct humeral...
The following taxonomic keys are adapted in part from the subgeneric and species descriptions and keys produced by McGinley (2003), Gibbs et al. (2013) and Gardner and Gibbs (2022). Additional identification information was provided by Jason Gibbs, Thilina Hettiarachchi (University of Manitoba), and Joel Gardner (Washington State University). While these...
