要旨:
Plastron respiration in submerged Myrmecodesmus species is possible when their hydrophobic secretion layer (cerotegument) on tergites extends to sternites and covers all spiracles in the coxal region. Advanced juveniles and subadults but not adults of M. adisi (Hoffman, 1985) from Central Amazonian floodplains possess this functional cerotegument. Yet it is absent from M. duodecimlobatus (Golovatch, 1996) and M. hastatus (Schubart, 1945) from non-flooded uplands
