dc.description.abstract Although originally described from St. Vincent in the Lesser Antilles, the goblin spider genus Ischnothyreus Simon appears to be an Old World taxon that is represented in the New World only by two presumably introduced, pantropical, synanthropic species: I. peltifer (Simon) and I. velox Jackson. Two specific names based on New World specimens (I. barrowsi Chamberlin and Ivie from Florida, and I. indressus Chickering from the Lesser Antilles) are placed as junior synonyms of I. velox, which is newly recorded from Mexico, Panama, Jamaica, Hispaniola, Venezuela, Brazil, Madagascar, the Philippines, the Marshall Islands, Hawaii, the Marquesas Islands, and New Caledonia. A third species, I. browni Chickering, that is supposedly from Costa Rica was apparently based on mislabeled specimens that are actually from the Philippines. The type specimens of I. browni resemble those of the Seychelle species Ischnothyrella jivani (Benoit) in that the dorsal abdominal scutum of males is extremely weak and that of females is either greatly reduced or entirely lost. Both species nevertheless share the synapomorphies of Ischnothyreus, and the generic name Ischnothyrella Saaristo is therefore placed as a junior synonym of Ischnothyreus. en_US
