I have been much interested in Heteroonops spinimanus  (Simon) for many years. Simon (1891) described the species from females collected on St. Vincent, B. W. I. In 1892 he reported the species from Venezuela. Dr. Petrunkevitch, in his study of Puerto Rican spiders, (1929), stated that he had males and females for study in the collection of the American Museum of Natural History. These were collected in 1915 in San Juan, Cayey, Naranjito and Coamo Springs. He regarded the males, taken in these localities, as belonging with the females and described a male from San Juan as the male of Oonops spinimanus  Simon. This identification has been widely accepted up to the present time. I have had the specimens that were apparently studied by Dr. Petrunkevitch also on loan from the American Museum of Natural History. It has been very disappointing to find almost all of the specimens, believed to be those studied by Dr. Petrunkevitch, in a very dismembered and almost useless condition. I think there is no question about the status of the females involved but I am obliged to regard the identification of the males as open to serious doubts. Dr. Petrunkevitch noted a considerable degree of variation among the males in respect to the appearance of the palpal conductor and embolus, indicating, perhaps, a mixture of species. I have spent much time in searching through my extensive collection of Oonops for males which could be matched with the well established females but without success. I am of the opinion that the males identified as Oonops spinimanus  Simon by Dr. Petrunkevitch really belong with Oonops castellus Chickering  , now believed to be rather widely distributed among the West Indies. I readily concede, however, that there is no certainty at the present time.

Records. In addition to the records cited above the following should now be added in order to bring the record up to date: Dr. Gertsch recognized the species from Florida in 1936, where it is now known to be fairly common (Chickering, 1969). Miss Bryant (1940) reported the finding of females in Cuba. I have taken many females in the following localities during my collecting trips in 1954, 1957 - 1958, 1963 - 1964, 1965 and 1966: Jamaica, W. I. \ where the species seems to be abundant; St. Thomas, St. John and St. Croix, U. S. Virgin Islands; Puerto Rico, W. I.; St. Lucia. St. Kitts, Nevis and St. Vincent, all in the British West Indies; Trinidad, W. I.; Panama Canal Zone and parts of Panama, particularly in the mountainous regions; and finally in Costa Rica.
