REMARKS This species was described by Budde-Lund (1885) as Metoponorthus madagascariensis and latter placed by the same author (1908) in the genus Porcellio Latreille, 1804 and subgenus Agnara established by him. Schmalfuss & Ferrara (1978) described Protracheoniscus inexpectatus from 28 specimens captured in Guinea-Bisáu , being this species synonymous with the previous ( Schmalfuss 2003 ). It is recorded for the first time for São Tomé . DISTRIBUTION Agnara madagascariensis is known from Guinea-Bisáu , Senegal , Madagascar , Arabia, south China , Taiwan , Ascensión island, Colombia and Venezuela ( Budde-Lund 1885 , 1908 ; Schmalfuss & Ferrara 1978 ; Taiti & Ferrara 1991 ; Schmalfuss 2003 ; López-Orozco et al. 2022 ).
