“…However, a southern origin of the beetles and dispersal through Antarctica with later contraction to the present distribution could be on the more recent side of our estimated range. The surviving Araucaria associated bark beetle lineages, though now very isolated, could have originated either in Antarctica (where Upper Cretaceous Araucariaceae fossils have been reported, Zastawniak (1994)) or in the Australian region and have dispersed to both Southern continents (South America and Australia) when these land masses where still close to each other (70 Mya: Pollock (1995); Rosen (1978) and Thayer (1985)). The most compelling evidence on the question of origins is the restriction of Tomicini to the basal Araucaria sections Bunya, Intermedia and Araucaria, plus the basal species in the most derived section Eutacta, which is thought to have radiated post-Eocene (Setoguchi et al, 1998).…”

Studies of a variety of phenomena, ranging from rates of molecular substitution to rates of diversification, draw on estimates of geological age. Studies incorporating estimates of timing from fossils or other geological evidence are largely of relatively young, Tertiary divergences, to which older systems may provide useful comparisons. One apparently old assemblage comprises the beetle groups associated with the ancient genus Arau,caria that share comparable, ostensibly Gondwanan distributions with their host. Our previous studies suggested a possibly Cretaceous age for Araucaria associations in bark beetles. However, the absence of confirmed bark beetle fossils earlier than the Tertiary has been taken as evidence of Cretaceous absence, and their confirmed phylogenetic position within the primitively angiosperm-feeding weevil family rules out pre-angiosperm, Jurassic origins. Nevertheless, an early shift from angiosperms t o Araucaria seemed plausible in the light of Araucaria fossil history which spans the Mesozoic since the Jurassic. To resolve the phylogenetic affinities and to estimate divergence times of the Australian and South American bark beetle genera affiliated with Araucaria we analysed DNA sequences of nuclear and mitochondria1 genes: protein coding elongation factor alpha, enolase and cytochrome oxidase I. The most parsimonious reconstruction of the host relationships of Tomicini from the combined dataset corroborates the ancestral association with the genus Araucaria of both South American and Australian Tomicini. Bayesian estimation of divergence times indicates that the divergence between the Australian and the South American Araucaria-feeding taxa occurred at the very latest in the Cretaceous/Paleocene border and that the age of the first Scolytinae-Araucaria association would then be during the later stages of the Late Cretaceous, while other known beetle/Araucaria associations are Jurassic. 0 2001 The Linnean Society of LondonADDITIONAL KEY WORDS: Tomicinibark beetles -South America -Australiaphylogenycytochrome oxidase Ielongation factor l aenolase -Bayesian inferenceage estimation -Late Cretaceous divergence.

“…However, the monophyly is not well founded and the interrelationships of the families are largely unresolved despite of a considerable number of phylogenetic investigations (e.g. Crowson, 1966;Abdullah, 1973Abdullah, , 1974Doyen & Lawrence, 1979;Pollock, 1995;Pollock & Lawrence, 1995). A large number of studies on tenebrionoid larvae have been published.…”

“…The findings are compared to structural features of other tenebrionoid larvae, and a list of characters potentially useful for phylogenetic reconstruction and a character state matrix are presented ( Table 1). The data for most families were taken from the literature (e.g., Pollock, 1995;Pollock & Lawrence, 1995;Pollock et al, 2000;Young, 1991). A cladistic analysis was carried out even though it was apparent that the use of the larval characters alone would not be sufficient for a good resolution within the complex superfamily.…”

“…The head is always very distinctly prognathous with nearly parallel dorsal and ventral sides of the head. A distinct molar tooth is present on the left mandible of larvae of Prostomidae, Pythidae, Pyrochroidae, Inopeplidae and Othniidae (Young, 1991;Pollock, 1991Pollock, , 1995Pollock & Lawrence, 1995). Larvae of Prostomidae, Boridae, Mycteridae and Pyrochroidae are characterised by a tho rax, which is narrower than the head and the abdomen (Lawrence, 1991;Pollock, 1991), and the abdominal seg ment IX forms a plate-like structure, which articulates with segment VIII (Fig.…”

Abstract. Structural features of larvae and pupae of Prostomis mandibularis are described in detail. Larval features are discussed with respect to their functional and phylogenetic significance. The distinct asymmetry of the larval head, absence of stemmata, pres ence of a sensorial field on antennomere III, and elongated and broadened mandibles of pupae and adults are autapomorphies of Prostomidae. The placement o f Prostomis within Tenebrionoidea is suggested by the posteriorly diverging gula with well developed gular ridges and the anterior position of the posterior tentorial arms. Affinities of Prostomidae with the pythid-pyrochroid-lineage is supported by the pad-like structure of the maxillary articulatory area, the abdominal tergite IX extending to the ventral side of the segment, and the strongly pronounced prognathous condition. Presence of a distinct molar tooth is a derived feature shared by Pros tomidae, Pythidae, Pyrochroidae, Inopeplidae and Othniidae. A thorax narrower than the head and the abdomen, and a plate-like abdominal segment IX, which articulates with segment VIII, are possible synapomorphies of Prostomidae, Boridae, Mycteridae and Pyrochroidae. The strongly flattened, prognathous head and the strongly flattened body of larvae of Prostomidae are correlated with their habits ofboring in wood of decaying logs.
