A reassessment of the pycnogonid genus Stylopallene (Arthropoda, Callipallenidae) with description of a new genus

Abstract

The genus Stylopallene comprising only four species is reviewed. All species are recorded from Australia, predominantly from the southern and south-eastern coastlines in association with arborescent bryozoans. Sexual dimorphism in the scape segments is recognized in the genus for the first time. The status of Stylopallene dorsospinum is re-evaluated and assigned to the new genus Bamberene. A diagnosis of the new genus is provided along with additional images to complement existing figures.
