Rhodacarus ( Rhodacarus ) roseus .— Shcherbak, 1980: 43 . TYPE DEPOSITORY : National Museum of Natural History – Naturalis , Leiden , Netherlands . TYPE LOCALITY AND HABITAT : Netherlands , Haarlem , on decaying leaves . NOTES : Sheals (1958) recognised two forms of Rhodacarus roseus — R . roseus f. typica , with a V-shaped groove on the podonotal shield, and R . roseus f. simplex , without a groove. Sheals' R . roseus f. typica appears to match R . roseus , but his R . roseus f. simplex remains unidentified. Schweizer (1961) illustrated R . roseus without a podonotal groove, so the identity of those specimens must also be considered as doubtful. The name Rhodacarus roseus has been used in a large number of publications reporting faunistic and ecological studies of soil arthropods (e.g. Block, 1966 ; Costa , 1966 ; Lee, 1973b ; Sardar & Murphy, 1987 ). In view of the difficulty of identifying R . roseus and related species, it seems likely that this name has been applied to a number of different species. Bregetova & Shcherbak (1977) suggested that R . roseus sensu Sheals (1958) could be a misidentification of R . laureti . Sheals (1958) also considered Rhodacarus roseus to be a senior synonym of R . mandibularis . However, we follow other recent authors in considering these to be two different species (see under R. mandibularis ).
