Abstract

Damselflies of the genus Nesobasis (herein restricted) are the dominant Zygoptera on the Fijian Islands. In the southern islands that are the focus of this report the genus (divided into 3 groups) includes 20 species, of which 10 are newly described here. The erythrops group consists of erythrops SclysjelegastrumSclys, selysiTi\\yaxd, angulicoUis Tillyard (syn. subhumeralis Tillyard), leveri Kimmins, and the new speciesrufostigmajlavifrons, ingens, recava, flavostigma, and pedata. The longistyla group contains longistyla Selys, campioni Tillyard, and the new species caerulecaudata, monticola, and caerulescens. The comosa group contains comosa Tillyard, heteroneura Tillyard, aurantiaca Tillyard, and the new species malcolmi. The genus is remarkable for the morphological and colour variations of several species. © Crown 1990.
