Two new species of the endemic Australian stiletto fly genus Laxotela Winterton & Irwin are described and figured. Laxotela elongata sp. nov. is described from Queensland while Laxotela plata sp. nov. is described from south-eastern mainland Australia. Laxotela ornata (Kröber) comb. nov. (originally Spatulipalpa Kröber) was recently placed as incertae sedis within Therevidae, but is herein tran...

Eleven species of Mordellidae are newly recorded for New Brunswick, Canada. Six of these, Falsomordellistena discolor (Melsheimer), Falsomordellistena pubescens (Fabricius), Mordellistena ornata (Melsheimer), Mordellaria undulata (Melsheimer), Tomoxia inclusa LeConte, and Yakuhananomia bidentata (Say)are new for the Maritime provinces. Falsomordellistena pubescens is new to Canada. Pelecotoma f...

Ri6ea ornata seed oil was found to contain 12,13-epoxy-octadec-cis-9-enoic acid (vernolic acid, 22.0%) along with the other normal fatty acids like palmitic acid (24.2%), stearic acid (8.9%), oleic acid (17.1%) and linoleic acid (27.8%). The identification and characterization was based on Fourier transform infrared (FTIR), H-NMR, mass spectrometry (MS), gas–liquid chromatography (GLC)-techniqu...

Determining the distribution of cytotypes across the geographic distribution of polyploid complexes can provide valuable information about the evolution of biodiversity. Here, the phytogeography of cytotypes in section Cuthbertia (Small, 1903) Hunt, 1986 is investigated. A total of 436 voucher specimens was georeferenced; 133 new specimens were collected. Based on flow cytometry data, DNA conte...

Using up to 2456 bp mtDNA and up to 2716 bp nDNA of fresh samples and short sequences of three mitochondrial genes of historical museum material, we examine the phylogeography of Amyda cartilaginea. This data set provides evidence for the existence of deeply divergent genetic lineages which we interpret as three distinct species, two of which are polytypic. On the Great Sunda Islands, the distr...
