Abstract This study presents the first report of the occurrence of Dasymutilla gloriosa (Hymenoptera: Mutillidae) on Carmen, Cerralvo (Jacques Cousteau), and San Marcos Islands, Baja California Sur. Additionally, we collected D. connectens and D. gloriosa on the mainland of the Peninsula at the Sierra Laguna Reserve, that corresponds to the geographical distribution of these Dasymutilla species. Several individuals were collected in the coastal dune zone and the sandy zones within the shrublands on the islands and sandy areas inside the xerophytic shrubland and deciduous forest at Sierra La Laguna. Two hypotheses were drawn about the arrival of the mutillids to the islands: 1) islands biogeographical history, and 2) anthropogenic influence.

蓟花绒蚁（Dasymutilla gloriosa Saussure）在南下加利福尼亚州的分布与加利福尼亚湾南部群岛的新记录

摘要 本研究首次报道了在卡门、塞拉尔沃（雅克库斯托）和圣马科斯群岛，南下加利福尼亚州发生的 Dasymutilla gloriosa（膜翅目：Mutillidae）。此外，我们还在 Sierra Laguna Reserve 的半岛大陆上收集了 D. connectens 和 D. gloriosa，这与这些 Dasymutilla 物种的地理分布相对应。在沿海沙丘区和岛屿上的灌木地内的沙地以及拉古纳山脉的旱生灌木地和落叶林内的沙地中收集了几个个体。关于 mutilids 到达岛屿的两个假设：1) 岛屿生物地理历史，以及 2) 人为影响。
