THE SOUTHERNMOST RECORD OF SCHIZOMIDA IN SOUTH AMERICA, FIRST RECORDS OF SCHIZOMIDA FOR RIO DE JANEIRO AND OF STENOCHRUS CHAMBERLIN, 1922 FOR BRAZIL (ARACHNIDA, SCHIZOMIDA, HUBBARDIIDAE)

The order Schizomida has underwent in recent years substantial changes which caused the replacement of the old scheme of only a few genera by numerous generic names (REDDELL & COKENDOLPHER, 1995). The order is well distributed in the tropics worldwide, except for central-southern South America. There is a genus of the Hubbardiidae, Surazomus Reddell & Cokendolpher, 1995, which possesses many endemic species from northern South America, but the southernmost record of the order Schizomida in South America is from Amazonia. Sifting leaf litter specially looking for small arachnids during projects conducted in the Laboratory of Arachnology of the Museu Nacional-Rio de Janeiro, yielded no schizomids from central-southeastern Brazil. Surprisingly, sifting of litter from metropolitan Rio produced some females of the widespread species Stenochrus portoricensis Chamberlin, 1922, naturally occurring in Mexico and the Caribbean and introduced to many countries. Illustrations of the diagnostic features are given for specimens from the population of Rio. The Museu Nacional-Rio de Janeiro, Brazil is herein abbreviated as MNRJ.
