PART B ACTION PLANS The Native Grassland Conservation Strategy provides a strategic framework for the Action Plans in this section. Action Plans are statutory documents under the Nature Conservation Act 2014. Draft Native Grassland Conservation Strategy and Action Plans 122 NATURAL TEMPERATE GRASSLAND ENDANGERED ECOLOGICAL COMMUNITY ACTION PLAN Native Grassland Conservation Strategy and Action Plans 123 PREAMBLE Natural Temperate Grassland was declared an endangered ecological community on 15 April 1996 (Instrument No. DI1996-29 Nature Conservation Act 1980). Under section 101 of the Nature Conservation Act 2014, the Conservator of Flora and Fauna is responsible for preparing a draft action plan for listed ecological communities. The first action plan for this ecological community was prepared in 1997 (ACT Government 1997). This revised edition supersedes all previous editions. This action plan includes the ACT Native Grassland Conservation Strategy set out in schedule 1 to the ‘Nature Conservation (Native Grassland) Action Plans 2017’, to the extent it is relevant. Measures proposed in this action plan complement those proposed in the action plans for Yellow Box / Red Gum Grassy Woodland, and component threatened species that occur in Natural Temperate Grassland: Striped Legless Lizard (Delma impar), Grassland Earless Dragon (Tympanocryptis pinguicolla), Golden Sun Moth (Synemon plana), Perunga Grasshopper (Perunga ochracea), Ginninderra Peppercress (Lepidium ginninderrense), Button Wrinklewort (Rutidosis leptorhynchoides) and Baeuerlen’s Gentian (Gentiana baeuerlenii). CONSERVATION STATUS CONSERVATION OBJECTIVES Natural Temperate Grassland is recognised as a The overall objective of this plan is to conserve threatened community in the following sources: Natural Temperate Grassland in perpetuity as a viable and well-represented community across National its natural geographic range in the ACT.

WESTERMAN Department of Genetics and Human Variation, La Trobe University, Bundoora, Victoria, 3083, Australia Received3.xii.74 SUMMARY Samples of Phaulacridium marginaleweretaken from the North Island of New Zealand, together with further samples from three South Island populations. Seven of the North Island populations were found to be polymorphic for a small telocentric B chromosome. In only one case was the B chromosome significantly associated with an increased chiasma frequency. All three South Island populations contained B chromosomes. Seven of the nine N.I. popula- tions were also polymorphic for extra segments on the centric end of the chromosome. In six of them this polymorphism co-existed with that for B's. A new polymorphism was encountered in two populations. This was for a large block of heterochromatic material located at the centric end of one of the smaller medium-sized chromosomes which thus becomes acro- rather than telocentric. It would appear that the New Zealand grasshopper, Ph. marginale, is able to tolerate many different polymorphisms for extra heterochromatin. However, this ability is perhaps restricted to central populations. In this Context, the high level of occurrence of these polymorphisms in the North Island could be due to the better climatological conditions existing there compared to most of the South Island. 1. INTRODUCTION POPULATIONS of the New Zealand grasshopper Phaulacridium marginale are known to be polymorphic for both B chromosomes and for supernumerary segments on the smaller members of the chromosome complement (Martin, 1970; Westerman and Fontana, 1973; Westerman, 1974, 1975).

Legless lizards are superficially snake-like; they lack forelimbs, and the hind limbs are reduced to a scaly flap just above the vent. Whilst their eyes are lidless and snake-like, there are several features that distinguish legless lizards from snakes. Most legless lizards have an obvious ear aperture, lacking in all snakes, and a broad fleshy tongue, compared to the deeply forked tongue of snakes. Most legless lizards also have a tail that, when unbroken, is considerably longer than their body. In contrast, the tail of snakes is considerably Hooded Scaly-foot, Pygopus nigriceps shorter than their body. The genus Pygopus Illustration by Peter Robertson Wildlife Profiles P/L © differs from other legless lizards on the basis of the combination of the following features: head covered with enlarged, symmetrical scales; smooth (compared to keeled) ventral scales; and the possession of eight or more preanal pores. Two species of Pygopus occur in Victoria. The Hooded Scaly-foot is a large legless lizard, attaining a total length of 475mm, and a snout- vent length of about 180mm. Females reach larger sizes than males. Variable in colour, the Hooded Scaly-foot may be pale grey to reddish-brown on the dorsal surface and whitish on the ventral surface. The dorsal scales may be dark-edged, forming a reticulated pattern, or individual pale and dark scales may form a vague longitudinal pattern.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

The tribe Gazerini as previously delimited was found to be paraphyletic with respect to the genera Ceretes, Divana, Riechia, Frostetola, and Oiticicastnia. The genera Castnia, Geyeria, and Athis were also found to be non-monophyletic taxa. The mimicry pattern had multiple independent origins in the Neotropical castniids, and at least two lineages, Riechia and Prometheus, are involved in Batesian mimicry rings with unpalatable butterfly models in the tribes Acraeini and Heliconiini (Nymphalidae). We propose for Castniini 13 new synonymies and 27 new combinations. Geyeria strigata (Walker, 1854) is revalidated. The generic placements of Athis superba (Strand, 1912) and Castnia eudesmia Gray, 1838 are questionable, but presently upheld. © 2014 The Linnean Society of London, Zoological Journal of the Linnean Society, 2014, 170, 362–399. doi: 10.1111/zoj.12102 ADDITIONAL KEYWORDS: Batesian mimicry – new synonyms – taxonomy.
