Macrofossil specimens of Dacrycarpus and Acmopyle from south-eastern Australia are investigated. The specimens previously assigned to D. praecupressinus are revised, with one placed in a different genus and new species, Podocarpus witherdenensis, and some placed in a new species, D. latrobensis. One specimen is retained as the lectotype of D. praecupressinus. Dacrycarpus eocenica is re-examined and it is concluded that this species is not Dacrycarpus, but probably belongs to an extinct podocarpaceous genus. Dacrycarpus setiger is transferred to Acmopyle, and three new Acmopyle species, A. florinii, A. glabra and A. tasmanica, are described. It is hypothesised that during the Tertiary in south-eastern Australia stomatal distribution was reduced on Dacrycarpus and Acmopyle foliage. In Dacrycarpus the bilaterally flattened foliage type (which has a greater photosynthetic area than the bifacially flattened foliage) became rare or extinct after the Early Oligocene, prior to the extinction of the genus in the region. Acmopyle has not been recorded in the region after the Early Oligocene. A trend towards reduction in leaf size at high latitudes has previously been demonstrated in angiosperms but not gymnosperms and, along with the reduction of stomatal distribution, probably represents convergent evolution in response to climatic change.

A new species of mistletoe, Muellerina flexialabastra Downey & C.A. Wilson (Loranthaceae), from south-eastern Australia is described. The description of this new species is based on morphological and nuclear DNA sequence differences between it and the other four species of the genus: Muellerina celastroides, M.�eucalyptoides, M.�bidwillii and M.�myrtifolia. Several morphological attributes that separate this new species from its relatives: (i) the shape of the corolla, (ii) the direction flowers open in relation to the floral triad axis, (iii)�the shape of the flower umbel, (iv) leaf size, (v) location of epicortical runners and (vi) the host species. In addition, nuclear DNA analysis revealed 11 unique nucleotide base changes in this new species supporting its species status.

A new genus and new species of Munnopsidae Lilljeborg, 1864 is described. Nyctobadistes gen. nov. is represented by a single species, Nyctobadistes hamatus sp. nov. and was collected from off Tasmania, south-eastern Australia. Nyctobadistes gen. nov. is similar to Bathybadistes Hessler and Thistle, 1975, however, it can be distinguished from this genus by the combination of: the lack of apical setae on the dorsal body spines; the lack of lateral extensions on the natasomal pereonites; the slender carpus of at least pereopod 6; and the anterolateral margins of the pleon lack a spine and apical seta.

A new genus of Australian Phlaeothripidae is described, Klambothrips, to include a new species of gall-inducing thrips, K. myopori, that is a pest on the leaves of prostrate and upright Myoporum shrubs in California. A closely related thrips, Liothrips walsinghami Girault, is also included in this genus. This thrips is common in the coastal regions of south eastern Australia damaging the leaves of Myoporum insulare. Two further Australian thrips species are also placed in Klambothrips, both inducing leaf distortions on plants in the Asteraceae: Rhynchothrips annulosus Priesner on Cassinia, and Klambothrips oleariae sp. n. on Olearia. These thrips are all members of the “Teuchothrips complex”, and molecular data is presented indicating that the members of this complex constitute a series of separate lineages, one of which comprises the four species of Klambothrips.
