Symposium: Cryptic species

Unravelling Ochrogaster lunifer, a cryptic species complex.

Nicole McMullen (The University of Queensland). Ochrogaster lunifer Herrich-Schäffer 1855, commonly known as the bag shelter moth, is a relatively ubiquitous and abundant Australian native moth species. The caterpillars’ behaviour of processioning in single file has meant that many Australians are familiar with them. Their nest, a silken ‘bag’, is used as a retreat during the […]

First assessment of cryptic species in the gall-inducing scale insect Apiomorpha calycina (Coccomorpha: Eriococcidae).

Torin R. O’Connell (The University of Queensland); Lyn G. Cook (The University of Queensland). Apiomorpha calycina is a member of the most species-rich, gall-inducing scale insect genus.  Females induce vase-shaped galls on eucalypts in Eucalyptus sections Bisectae, Latoangulatae and Dumaria.  The species was first described by Tepper in 1893 from specimens collected on Eucalyptus dumosa in South Australia, but its distribution is

Is there cryptic species diversity in Apiomorpha strombylosa (Tepper)?

Chen-hsin Fan (The University of Queensland); Lyn G. Cook (The University of Queensland). Apiomorpha is the most species-rich genus of gall-inducing scale insect, and it is specific to Eucalyptus. It is also one of the most chromosomally diverse animal genera on the planet, with diploid karyotypes ranging from 2n=4 to about 192. Here, we test species boundaries

Morphological constraint obscures richness: a mitochondrial exploration of cryptic richness in Transversotrema (Trematoda: Transversotrematidae).

Scott C. Cutmore (Queensland Museum); Richard D. Corner (The University of Queensland); Thomas H. Cribb (The University of Queensland). Species of Transversotrema Witenberg, 1944 (Transversotrematidae) occupy a unique ecological niche for the Trematoda, living externally under the scales of their teleost hosts. Previous studies of the genus have been impeded partly by limited variation in ribosomal DNA sequence

Resolving the taxonomy of the Caladenia patersonii and C. reticulata Orchidaceae) species complexes in South Australia.

Andrew E. McDougall (The University of Adelaide ); Ed Biffin (State Herbarium of South Australia); Tim Hammer (The University of Adelaide and State Herbarium of South Australia); Michelle Waycott (The University of Adelaide and State Herbarium of South Australia). Intense taxonomic activity over the past thirty years within the Caladenia patersonii and C. reticulata species complexes in South Australia (~31

The velvet parachute (Marasmius elegans): a surprisingly variable species across its range with an uncanny QLD doppelganger.

Frances E. Guard (University of Southern Queensland); John Dearnaley (University of Southern Queensland); Teresa Lebel (State Herbarium of South Australia). 1. First described in SA by John Cleland in 1933, Marasmius elegans has been recorded across southern Australia and in New Zealand. Specimens from southeast Queensland were generally less robust and considered a possible second species. The first QLD

The complex history of the Macrozamia plurinervia complex helps explain the challenges of delimiting species in this group.

Alicia Toon (The University of Queensland); Paul Forster (Queensland Herbarium); Lyn Cook (The University of Queensland). The Macrozamia plurinervia complex is a group of cycads comprising seven described species that are distributed inland in southern Queensland and northern NSW. They occur in small populations, with many isolated by disturbed or cleared habitat. Four members of the complex are

Two cryptic conifer species separated by a mid-Miocene aridity barrier in southern Australia.

Michael D. Crisp (The University of Queensland); Meredith Cosgrove (CSIRO Plant Industry); Shota Sakaguchi (Kyoto University); Lyn G. Cook (The University of Queensland). The conifer species Callitris canescens (Cupressaceae), as currently circumscribed, has a disjunct distribution in south-west Western Australia and south-east South Australia. The species is absent from the low, arid limestone plateau of the Nullarbor
