Remarks: Pseudechiniscus . suillus is considered a complex of similar species ( Fontoura & Morais 2011) and, originally described from Europe ( Ehrenberg, 1853), now requires a re-description. Very similar species (e.g. P. facettalis or P. juanitae ) are also known from the South America and the presence of P. suillus sensu stricto is thus questionable and should be confirmed.
