New species of the genus Shelfordina Hebard with taxonomic and ecological notes and a key to the known Australian species (Blattodea: Ectobiidae: Pseudophyllodromiinae).

Three species in the ectobiid genus Shelfordina are highlighted with two described as new. The Orchid Cockroach, S. orchidae (Asahina) is included because of its occurrence in living orchid collections.

A revision of the genus Ima Tindale (Mantodea: Nanomantidae: Fulciniinae) with the description of a new genus.

Ima fusca is one of a number of unusual and infrequently collected Australian mantises about which relatively little is known. Long considered a single species, morphological studies instead revealed the presence of a second cryptic species. We here describe this species as Ima corymbia sp.

Revision of the genus Calofulcinia Giglio-Tos (Mantodea: Nanomantidae: Fulciniinae) in Australia.

The genus Calofulcinia comprises several species of small, cryptic mantis, three of which have been described from Australia. The genus is infrequently recorded and is thus very poorly known, and even basic questions of species delimitation and distribution have remained virtually unknown since the descriptions of these taxa. We here redescribe and figure the three known Australian species of Calofulcinia in full and provide a detailed key to Australian species.

Online social media tells a story of , , and (Orthoptera, Tetrigidae), rare Australian pygmy grasshoppers.

Knowledge on the pygmy grasshoppers of Australia is, despite the numerous endemics being described from this unique continent, still scarce. Of interest is the genus group, including genera Storozhenko, 2019, Storozhenko, 2019, Storozhenko, 2019 and Sjöstedt, 1921. The systematic position of this group, currently assigned to Batrachideinae (Bufonidini), is probably not correct.

Sound production in an Australian cockroach, (Walker) (Blattodea: Blattidae: Polyzosteriinae).

The large, diurnal Australian cockroach, Megazosteria patula (Walker), produces a sound when disturbed. The sound was found to be a form of stridulation caused by the rubbing of pegs on the underside of the thoracic segments against a ridge on the following segment.

Barrier precautions in trauma: is knowledge enough?

Objectives: The risk of blood and body fluid exposure and, therefore, risk of blood-borne disease transmission is increased during trauma resuscitations. Use of barrier precautions (BPs) to protect health care workers (HCWs) from exposure and infection has been codified in hospital rules and in national trauma education policy. Despite these requirements, reported rates of BP compliance vary widely.
