Identification
Distinguished from other phalangodid by genital and other subtle structural characters, as is typical for laniatorean harvestman . The single known Wespus arkansasensis is currently known only from its type locality in Arkansas. Definitive identification requires examination of male genitalia () and other minute morphological features visible only under microscopy.
