A review of the weevil fauna (Coleoptera, Curculionoidea) of Araucaria angustifolia (Bert.) O. Kuntze (Araucariaceae) in South Brazil

Abstract

Revista Brasileira de Zoologia 21 (3): 505-513, setembro 2004Araucaria Jussieu, 1789 trees, the oldest extant conifers, have an evolutionary history stretching more than 200 Mio years. The 19 recent species of this genus have a disjunct distribution (South America and Oceania) and form, under natural conditions, highly diverse mixed forests in tropical and subtropical regions of the Southern Hemisphere. Both the high geological age and the disjunct distribution predestinate Araucaria trees for evolutionary biological studies of insect-plant relationships. Today, we know several insect groups restricted in their occurrence to recent Araucariaceae like the leaf beetle subfamily Palophaginae (Megalopodidae), the weevil tribe Araucariini (Cossoninae, Curculionidae) or the bark or ambrosia beetle genera Hylurdrectonus Schedl, 1938, Hylurgonotus Schedl, 1951, Pachycotes Sharp, 1877 and Xylechinosomus Schedl, 1963 (KUSCHEL 1966, KUSCHEL & MAY 1996, MECKE 2000, WOOD 1986). An important question is, if there already existed Araucaria-insect associations before the splitting of Gondwana began and the continents were completely separated and if so, how these insects evolved in their long distant biogeographical regions. To answer these ques-

3.7. Curculionidae Latreille, 1802

“…This kind of behavior is well described for all species of Araucarius Kuschel (1966), Inoso mus rufopiceus Broun (see , Protoplatypus velutus , and Phylloplatypus pandani and has recently also been observed in some species in Onycholipini [e.g., Eurycorynophorus scabriculus Voss (see Mecke & Galileo 2004), Stenos celodes Konishi, Stenocelis Wollaston, and related genera] and Rhyncolini (e.g., Stenancylus Casey; B. H. Jordal, unpublished data). However, some species in several unrelated cossonine lineages have been observed to enter the host as adults in a similar manner to the Scolytinae.…”

A new species of Halorhynchus from Madagascar (Coleoptera, Curculionidae, Cossoninae, Onycholipini)

“…Generally, cossonine weevils prefer dead and decomposing plant tissue, usually boring and scarring recently felled trees (Jordal 2014;Pierce 1918); some, such as Caulophilus Wollaston (Kuschel 1962;Pierce 1918) and Dynatopechus Marshall (Zimmerman and Anderson 1949), are serious pests of grains and beans, respectively. Some cossonines in Dryotribini, Neumatorini, Onycholipini, and Pentarthrini are endogean, dwelling deep in soil and humus (Morrone and Hlavac 2017), while others in Rhyncolini, Proecini, and some Onycholipini create complex galleries in wood involving adult and larval tunnels and egg-niches, similar to those created by scolytine bark and platypodine ambrosia beetles (Kuschel 1966;Osella 1982;Kato 1998;Mecke and Galileo 2004;Jordal 2014). Finally, the newly transferred Phylloplatypus Kato (Kuschel et al 2000;Jordal et al 2011) feeds on and mines the living leaf tissue between the veins of Pandanus Parkinson and are able to transmit fungal pathogens from infected to uninfected leaves (Sugiura and Masuya 2010), the spores of which may be carried by the adult in mycangia located on the forecoxae (Morimoto and Kojima 2004).…”

Geographic distributions, host plants and biology of species in the genus Huequenia (Coleoptera: Cerambycidae), with new records from Southwestern Argentina

“…Some works have been made about extant Araucaria-insect associations, related to Araucaria angustifolia (Bertol.) Kuntze (Pastrana 1950;Mecke et al 2000aMecke et al ,b, 2001Mecke et al , 2004aMecke & Galileo 2004), Araucaria araucana (Molina) Koch (Hodge 1997;Turienzo 2005Turienzo , 2006Ferrer et al 2007), Araucaria laubenfelsii Corbas (Mecke 2004b), Araucaria muelleri (Carr.)
