Alate queen, FOCOL2122 ( ZMHB ) [ type queen of Cataulacus praetextus var. sumatrensis – now junior synonym of C. praetextus ]. Literature. Viehmeyer (1916) , Overbeck (1924) [both as C. praetextus var. sumatrensis ]. Localities. Jurong Road; Mandai Road; Nee Soon Swamp Forest. Habitat/Ecology. Workers of this species were found together with Tetramorium obtusidens Viehmeyer, 1916 and Technomyrmex albipes ( Smith, 1861 ) in the same withered branch of a roadside tree; workers have also been collected from Nepenthes pitcher cups. The species appears mostly associated with old/ mature secondary forests in Singapore , including swamp forest.
