Macquarie Island is an oceanic island located 1000 km south-east of Tasmania. The island, which lies close to but north of the Antarctic Convergence, is the southernmost island in the world with a fairly complete cover of vegetation. However, the vascular flora is impoverished and consists of only 46 species. During the period of late January to late April of 1995, 412 field collections of myxomycetes, representing at least 22 species in 11 genera, were obtained during the course of an intensive survey of fungal biodiversity on Macquarie Island. Moist-chamber cultures prepared with various types of plant debris yielded only 14 collections, but this total included three additional species and two additional genera. All but four of the species we recorded from the island are new records for the South Polar Region. Most field collections were associated with Stilbocarpa polaris (Araliaceae) and Pleurophyllum hookeri (Asteraceae), the usual dominants in the herbfield communities that commonly occur on upper beach slopes and coastal terraces. Trichia verrucosa (80 collections), Diderma alpinum (78) and Craterium leucocephalum (59) were the most consistently abundant myxomycetes. Other species represented by ≥15 collections were Didymium cf. dubium, Collaria lurida, Lamproderma arcyrioides and Didymium macquariense. The latter is a species new to science that was described from material collected during the present study. All of the species of myxomycetes now known to occur on Macquarie Island are members of the Trichiales, Physarales, Stemonitales or Echinosteliales; no member of the Liceales or Ceratiomyxales was ever collected.

First documented record of barn swallow (Hirundo rustica) in the Antarctic Here we report a photo-documented record of a barn swallow (Hirundo rustica) from the South Shetland Islands. We also review previous records of passerine vagrants in the Antarctic (south of the Antarctic Convergence Zone). This barn swallow is the first recorded member of the Hirundinidae family on King George Island and is only the second passerine recorded in the South Shetland Islands. This sighting, along with previous records of austral negrito and austral trush represent the southernmost sightings of any passerine bird anywhere in the world.

Two New Species

In this paper, two new species ofOnychocamptusDaday, 1903 are described from Thailand:Onychocamptussatunensissp. n.andOnychocamptustratensissp. n.The following features mainly distinguishO.satunensissp. n.from known species: internal sausage-like and internal rounded structures on cephalothorax and one outer seta on the male P5 exopod that is as long as the supporting segment. In contrast, the cephalothorax ofO.tratensissp. n.is smooth but has rounded integumental window-like structures, and the outer seta on the male P5 exopod is two times as long as the supporting segment.Onychocamptusanomalusshows the highest similarity with the two new species, but in contrast to both Thai species, it has only one seta on the exopod of the antenna. In addition, in the present study, two additional species,O.bengalensisandO.vitiospinulosa, are newly recorded in Thailand. Thus, the number ofOnychocamptusspecies recorded in Thailand increases to five species. A key to all known species of this genus in the world is also proposed.

Parapachymorpha is one of eight genera within the tribe Medaurini of subfamily Clitumninae (Phasmatidae). It was established by Brunner von Wattenwyl (1893), with the type species Parapachymorpha nigra by subsequent designation of Kirby (1904), from Myanmar. Species of this genus are widely distributed in oriental tropics (Laos, China, Thailand, Myanmar, Vietnam and Cambodia), with only 11 known species in the world (Brock et al. 2018, Ho 2017). Species of the genus Parapachymorpha can be recognized by following characters (Brunner von Wattenwyl 1893;1907, Henmemann & Conle 2008, Ho 2017): 1) body robust in female and slender in male with long leg in relation to the length; 2) body surface of female granulose or spinose; 3) mesonotum of female more and less expanded posteriorly; 4) abdominal tergites lacking expanded prostero–lateral angles in both sexes; 5) laminal supraanalis undeveloped in female; 6) semi–tergite of male irregularly rectangular, with an additional finger­–like ventro–apical appendix on the lower margin and reduced or absent; 7) egg capsule oval to oblong and covered with a raised net–like structure in lateral view; 8) micropylar plate oval; 9) operculum concave or convex. In the present study, we describe additional species, Parapachymorpha minuta sp. nov. from Laos, with photographs of both sexes of adults and egg.

Abstract Sir Douglas Mawson is a well-known Antarctic explorer and scientist. Early in his career, he recognised opportunities for commerce in Antarctic and sub-Antarctic regions. While at Cape Denison, Antarctica, in 1913 on the Australasian Antarctic Expedition (AAE), the Adelie Blizzard magazine was produced. Mawson contributed articles about Antarctic natural resources and their possible use. Later, he advocated Australia be involved in pelagic whaling. He collected seal skins and oil for their commercial value to be assessed by the Hudson’s Bay Company. During the AAE, Mawson visited Macquarie Island where an oiling gang was killing southern elephant seals and royal penguins. Mawson was concerned that they were over-exploited and lobbied successfully to stop the killing. His plans for Macquarie Island included a wildlife sanctuary, with a party to supervise access, send meteorological observations to Australia and New Zealand, and be self-funded by harvesting elephant seals and penguins. Macquarie Island was declared a sanctuary in 1933. Although Mawson has been recognised as an early proponent of conservation, his views on conservation of living natural resources were inconsistent. They should be placed in their historical context: in the early twentieth century, utilisation of living natural resources was viewed more favourably than currently.

Geophysical Measurements

When geophysical measurements are made from the air, it is important to know the position of the aircraft. The position at any time is usually known from a combination of position-fixing and dead-reckoning systems. In-flight optimization of this combination is a well-studied subject. When post-flight track plotting is required for geophysical survey, use can be made of both the initial and terminal position fixes to correct the dead-reckoning track and hence improve on the in-flight version. This technique is applied to compute the track of aircraft conducting ice thickness measurements in the Antarctic, and the effect of certain errors is evaluated. The algebraic results are equally applicable in parts of the world where better navigational aids are available. A relation is derived between the track plotting errors and die errors in the geophysical measurement such that the precision of one is not degraded by errors in the other.

A New Species

Preliminary surveys of brackish and freshwater habitats in the southeast and east of South Korea produced a total of fifteenspecies. Ten of these species are new records for Korea, and one additional species, belonging to the genus Tanycypris, isnewly described herein. Twenty-seven species of nonmarine ostracods are now reported from Korea, but this is probablyonly a small proportion of the actual number of species inhabiting the peninsula. The presence of Dolerocypris ikeyaiSmith & Kamiya, 2006, Cryptocandona brehmi (Klie, 1934), Cryptocandona tsukagoshii Smith, 2011, Physocypria nip-ponica Okubo, 1990 and Vestalenula cylindrica (Straub, 1952) on the Korean Peninsula demonstrates that these species are also distributed on the continent, and are not endemic to Japan.
