Five species of epibenthic pycnogonids collected on the giant lion´s-paw scallop Nodipecten subnodosus are recorded. A new species of Eurycyde, Eurycyde bamberi, is described. Of the 19 species known in this genus; the new species is closest to Eurycyde hispida Kroyer, 1844 but differs from it in the absence of plumose spines and the shapes of the lateral process, first coxa, and ocular tubercle. The new species represents the third member of Eurycyde from the eastern Pacific in addition to Eurycyde spinosa Hilton, 1916 and Eurycyde clitellaria Stock, 1955. Besides Eurycyde bamberi, the following species were collected: Nymphopsis duodorsospinosa Hilton, 1942c; Callipallene californiensis (Hall, 1913); Nymphon lituus Child, 1979; and Pycnogonum rickettsi Schmitt, 1934. Pycnogonum rickettsi is recorded for first time from Mexican waters, as is Nymphon lituus from the western coast of Baja California Peninsula. Each of these four species are re-described and re-illustrated in order to fill in existing gaps in the literature of the region.
记录了在巨型狮爪扇贝结节栉孔扇贝上采集到的5种底栖海蜘蛛。描述了一种新的宽蛛蟹属物种——班氏宽蛛蟹。在该属已知的19个物种中，新物种与1844年克勒耶描述的多刺宽蛛蟹最为接近，但在没有羽状刺以及侧突、第一基节和眼瘤的形状上与之不同。新物种是东太平洋宽蛛蟹属的第三个成员，另外两个成员分别是1916年希尔顿描述的多刺宽蛛蟹和1955年斯托克描述的具环宽蛛蟹。除了班氏宽蛛蟹，还采集到了以下物种：1942年希尔顿描述的双背刺仙女蟹；加州美丽海蛛（霍尔，1913年）；1979年蔡尔德描述的舟形海蛛；以及1934年施密特描述的里克茨海蛛。里克茨海蛛首次在墨西哥海域被记录，舟形海蛛首次在南下加利福尼亚半岛西海岸被记录。对这四个物种中的每一个都进行了重新描述和重新绘图，以填补该地区文献中现有的空白。
