In both groups the male embolus is not a separate sclerite but merely the pointed tip of the tegulum, and the lateral ducts of the internal female genitalia are generally not folded anteriorly. As defined, the bispinosus group includes those species in which the male endites have lateral spurs and the bicolor group those species in which the male endites lack spurs. Insular evolution in the bicolor group and the use of the scanning electron microscope in studying genitalia are discussed. Fourteen new species are described: prominens from Central America, trifidus from Panama; digitus and planus from Costa Rica; parallelus from Nicaragua; rotundus from Chiapas; dilatus and erectus from Hispaniola; tomaculus, oculus, contractus, and inclinatus from Cuba; giganteus from Jamaica; and triangulus from the Canal Zone. The males of borinquensis Gertsch and californicus Banks and the female of cadulus Chickering are described for the first time. Four new synonymies are established: domandus Chickering with mulcetus Chickering, and parvulus Banks, inornatus (Banks), and deceptus floridanus (Chamberlin and Ivie), all with deceptus (Banks)"--P. 3.9710946 bytesapplication/pdfen-USTrachelasSpiders -- North AmericaSpiders -- Central AmericaSpiders -- West IndiesArachnida -- North AmericaArachnida -- Central AmericaArachnida -- West Indiestext
