Abstract
Abstract. A description and diagnosis are given for Heterothrips ephemerus sp. nov. collected from flowers of Krameria erecta Willdenow (Krameriaceae) shrubs in the Mojave Desert in southern Nevada, U.S.A. Flowers have an unusual, bilateral structure and contain elaiophores that secrete oils collected by specialist bees. Shrubs flowered for approximately 11 days following convective rainfall during summer. Adults occurred early during flowering with numbers of females exceeding males by approximately 12:1. Larvae were more abundant and reached the maximum number per flower, in flowers containing thrips, near the end of the flowering period. The near absence of other species of thrips suggests H. ephemerus is a specialized inhabitant of K. erecta flowers.
期刊介绍：
The Pan-Pacific Entomologist (ISSN 0031-0603) is published quarterly (January, April, July and October) by the Pacific Coast Entomological Society, in cooperation with the California Academy of Sciences. The journal serves as a refereed publication outlet and accepts manuscripts on all aspects of the biosystematics of insects and closely related arthropods, especially articles dealing with their taxonomy, biology, behavior, ecology, life history, biogeography and distribution. Membership in the Pacific Coast Entomological Society includes subscription to The Pan-Pacific Entomologist, and Society Proceedings typically appear in the October issue of each volume.
