| abstract | The larvae of Paratrombium Bruyant, 1910 (Acarina: Trombidiidae) of Australia and Papua New Guinea are described, from four new species: P. australe, sp.nov. and P. lindsayi, sp.nov. from southern Australia, P. curculionis, sp.nov. from northern Queensland, and P. anemone, sp.nov. from Papua New Guinea. the larvae of P. australe and P. lindsayi are correlated with adults by experimental rearing, with description of the ovum and prelarva, and attempts to find suitable larval hosts; these larvae experimentally parasitized small Diptera and Hymenoptera, and a species of Mantispidae (Neuroptera). The adults of P. australe and P. lindsayi are compared with previously described Australian adults of Paratrombium. Nomenclatural changes for previously described Australian adults of Paratrombium are proposed. |
