Two species of Mothocya Costa, in Hope, 1851 are reported from the Virgin Islands. Mothocya xenobranchia Bruce, 1986 was collected from St. John Island from the gills of the Atlantic needlefish, Strongylura marina, which is a new locality record and also confirms a previously uncertain host identity. Mothocya bertlucy sp. n. is described from St. Thomas, St John and Guana Islands, from the gills of the redlip blenny, Ophioblennius macclurei, the first record of a blenny as host for any Mothocya. The distinguishing characters of Mothocya bertlucy sp. n. include its small size (< 9 mm) and eyes, the slender pleotelson with a narrowly rounded caudomedial point, extended uropod peduncle and uropods which do not extend past the pleotelson posterior margin, and the narrow pleon which is only slightly overlapped by pereonite 7.
据报道，在维尔京群岛发现了两种1851年霍普所描述的莫托蟹属（Mothocya Costa）物种。1986年的异鳃莫托蟹（Mothocya xenobranchia Bruce）是从圣约翰岛的大西洋针鱼（Strongylura marina）鳃上采集到的，这是一个新的产地记录，同时也证实了之前不确定的宿主身份。新物种伯特露西莫托蟹（Mothocya bertlucy sp. n.）是从圣托马斯岛、圣约翰岛和瓜纳岛的红唇鳚（Ophioblennius macclurei）鳃上发现的，这是莫托蟹属以鳚鱼为宿主的首次记录。伯特露西莫托蟹的显著特征包括体型小（<9毫米）、眼睛小、细长的尾节，其尾内侧尖端狭窄圆润，尾足柄延伸，尾足不超过尾节后缘，以及狭窄的腹部，仅被第7胸节略微覆盖。
