Agathis dimidiata Brullé, 1846 Agathis dimidiata Brullé, 1846: 487. Holotype unknown, 3; Type locality: Hobart, Tasmania. Parrott, 1953: 198 [catalogue]; Shenefelt, 1970b: 330 [catalogue]; Yu et al., 2005 [catalogue]. Comments. The holotype of Agathis dimidiata Brullé is unknown and presumably lost. During this study, no material examined could be matched with the original description which defines colour and the dorsal surface sculpturing relatively well. However, the original description is insufficient, with no detail regarding mouth parts, tarsal claws or wing venation provided, so we are unable to confirm its generic placement. In addition, the holotype was collected from Hobart over a 150 years ago. The habitat of this area has undergone a dramatic transformation since European settlement and if A. dimidiata ’s natural range was confined to the Hobart region then there is the real possiblity that the species could now be extinct. For these reasons we hereby designate A. dimidiata as a nomen dubium.
