Platnickina adamsoni is commonly found in tropical America, and widespread across the world including Asia (Yoshida 2003; World Spider Catalog 2025). Although the general appearance of P. adamsoni resembles Y. mneon, they can clearly be distinguished by the genital morphology (Figs 2A–F, 3A–F, 4A–J vs 8C–E). Moreover, P. adamsoni usually display synanthropic habits, inhabiting walls of buildings, gardens and yards (Fig. 8A, B; Yoshida 2003).
