Diagnosis

Males differ from those of Ischnothyreus peltifer (Simon, 1892) in lacking a protuberance on the base of the fang; palp with rounded bulb and sperm pore larger ( Platnick et al. 2012: figs. 104 and 107; Brescovit et al. 2019: figs. 26-30). Females can be recognised by the boat-shaped structure on the postepigastric scutum (Fig. 6 G).

Distribution

Pantropical; newly recorded from China.
