Calohypsibius ornatus ( Richters, 1900 ) sensu lato [T] Macrobiotus ornatus Richters ( Heinis 1914 ) Hypsibius ( C. ) ornatus ( Mihelčič 1967 ) H. ( C. ) ornatus ( Mihelčič 1972 ) Terra typica : Ireland (Europe) Argentina : • 41°12′S , 71°50′W ; 1,000 m asl : Rio Negro Province, Rio Negro Province, Tronador (Ventisqueros) [Ventisquero Negro del Cerro Tronador], lichens on single, trees in full sun. Mihelčič (1967) • Undefined localities cited according Mihelčič (1967) , dry mosses and lichens on rocks in full sun. Mihelčič (1972) Bolivia : • 16°20′S , 68°23′W ; 4,650–4,700m asl : La Paz, Cordillera de la Real de los Andes, La Cumbre, subnival floor, cushion moss. Garitano-Zavala (1995 , 1996 ) Colombia : • 04°35′N , 74°02′W ; 3,300 m asl : Bogota Department, Páramo Cruz Verde, moss ( Sphagnum sp.) mud. Heinis (1914) Record numbers: Argentina : 2, Bolivia : 1, Colombia : 1; total: 4. Remarks: This species often occurs rarely and in small numbers and has been reported with extremely high levels of intra-specific variation and a wide geographic range (i.e. numerous mainly Holarctic localities with single localities in other zoogeographical regions, Ramazzotti & Maucci 1983 , McInnes 1994a ). However, these properties are also symptomatic of a species complex, so we suggest this species requires integrative taxonomy (molecular and morphology) to establish the species sensu stricto and validity of South American examples.
