Diagnosis. Males of Ischnothyreus peltifer can easily be separated from those of I. velox by the large protuberance on the base of the cheliceral fang in males ( Fig. 23 View Figs 20-30 ) and narrow, posteriorly situated, sinuous ridge on the postepigastric scutum ( Fig. 22 View Figs 20-30 ) in females.

Description. Male and female, see PLATNICK et al. 2012b:7, figs 1-99.

Distribution. According to PLATNICK et al. (2012b), this Pantropical species was probably introduced in Americas from Asia. Our records indicated that it was present only in three Brazilian states, the Northern State of Pará, the Northeastern State of Bahia and in the Southeastern State of São Paulo ( Fig. 59 View Figs 58, 59 ). Judging by the records obtained, at the moment this species is not sympatric with I. velox in Brazil.
