The genus Pristaulacus Kieffer, 1900 (Hymenoptera: Aulacidae) in Vietnam and Northeastern Laos with descriptions of ten new species.

The genus Pristaulacus Kieffer (Hymenoptera, Aulacidae) from Vietnam is revised with eight new species, namely P. alius Long, sp. nov.

Ichnoverruca nom. nov., a replacement name for the genus Verruca Sheng amp; Sun, 2018 (Hymenoptera, Ichneumonidae) non Schumacher, 1817.

The name Verruca was proposed for a new genus of wasps described by Sheng Sun (2018) with the type species Verruca dentia Sheng Sun, 2018 in the family Ichneumonidae (Hymenoptera). However, it cannot be used as a valid generic name due to homonymy as the genus Verruca was established by Schumacher (1817) in the barnacle family Verrucidae (Cirripedia, Verrucomorpha). Verruca Schumacher is a valid generic name in Verrucomorpha.

Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia.

The Aulacidae is a small family of Hymenoptera that are parasitic on wood-boring beetles and wasps. They have a worldwide distribution but are generally poorly studied, particularly for the southern hemisphere. This study is part of a series that aims to describe the Australian fauna which is relatively species-rich compared with other regions.

A new species of the endemic Australian genus Hyptiogaster Kieffer Hymenoptera: Gasteruptiidae).

Hyptiogaster arafura sp. nov. is described from Arafura Swamp, Northern Territory, Australia, as the eleventh species of Hyptiogaster Kieffer (Hymenoptera: Gasteruptiidae).

The gasteruptiid wasp fauna of New Caledonia, with description of three new species of Gasteruption (Hymenoptera: Evanioidea: Gasteruptiidae).

The rarely collected gasteruptiid wasp fauna (Evanioidea: Gasteruptiidae) of New Caledonia is reviewed. Previously only two species of Pseudofoenus (Hyptiogastrinae) were known. Here, we record the subfamily Gasteruptiinae from New Caledonia for the first time and describe three new species of Gasteruption: G.

Synopsis of the hymenopteran fauna of Lord Howe Island with a preliminary checklist of species.

Lord Howe Island is an eroded remnant of a shield volcano approximately 600 km northeast of Sydney, New South Wales, Australia. It has fascinated biologists for more than a century because of its unique and iconic fauna and flora, and was declared a World Heritage Site in 1982. Although the terrestrial invertebrate fauna is reasonably well known for many groups, most Hymenoptera, apart from ants, have received scant attention.

Gasteruption youngi sp. nov. (Hymenoptera: Evanioidea: Gasteruptiidae) from South Australia; an unusual species with trichoid sensilla on the ovipositor sheaths.

Gasteruption youngi, sp. nov. (Evanioidea: Gasteruptiidae) is described based on several female specimens from South Australia.

Happy birthday Willi Hennig!-Hyptia hennigi sp. nov. (Hymenoptera: Evaniidae), a fossil ensign wasp from Eocene Baltic amber.

The ensign wasp genus Hyptia Illiger was previously known from 52 extant New World species and one fossil species from Lower Miocene to Upper Oligocene Mexican amber. Hyptia hennigi sp. nov.

Review of the hymenopteran fauna of New Caledonia with a checklist of species.

The hymenopteran fauna of New Caledonia is reviewed and compared with that of Australia and New Zealand, as well as other islands in the south-west Pacific. In conclusion, several different scenarios (e.g.

Cretevania bechlyi sp. nov., from Cretaceous Burmese amber (Hymenoptera: Evaniidae).

The fossil evaniid wasp Cretevania bechlyi sp. nov., is described based on a well preserved female specimen from Cretaceous Burmese amber.

Competition between solvent quenching and indole quenching of 9-fluorenone: a spectroscopic and computational study.

The interaction between 9-fluorenone, various indoles and solvents has been studied using steady-state fluorescence spectroscopy and quantum chemical calculations. It was determined that polar protic solvents such as methanol and ethanol significantly quenched the fluorescence of 9-fluorenone but various indoles reversed the solvent quenching. The effect of various solvents on the 9-fluorenone carbonyl vibration was investigated using infrared spectroscopy.
