Crematogaster udo ; Emery, 1922: 132 [Raised to species]. Crematogaster udo ; Emery, 1922: 132 [Combination in C . ( Orthocrema )]. Crematogaster udo ; Blaimer, 2012c: 55 [Combination in C . ( Orthocrema )]. Comments: We have not been able to examine the type material of C . udo . Forel (1905) referred the affinity with C . fritzi Emery in the original description, whereas Menozzi’s key (1935) clearly separated C . fritzi from other Orthocrema species, including C . udo , by having two pairs of hairs on mesosomal dorsum. Taxonomic relationship of C . udo with C . fritzi will remain unresolved until the type material is examined.
