Jo-Anne Nina Sewlal

Abstract


Currently, 50 families of spiders are documented and confirmed to be found in Trinidad and Tobago (Sewlal and Cutler 2003; Sewlal 2010) belonging to the infraorders Araneomorphae and Mygalomorphae. A search of the database of the Field Museum, Chicago, USA has yielded the presence of two more families, Nemesiidae (Mygalomorphae) and Tengellidae (Araneomorphae), bringing  the  total  number  of  families  recorded  from Trinidad and Tobago to 52.
