The geographical range of Ogyris zosine (Hewitson, [1853]) in Western Australia was previously considered to be restricted to the Kimberley and Pilbara regions in the northern and northwestern areas of the state. Here we document several new distribution records from the arid zone of inland central and southern Western Australia (south of the Tropic of Capricorn) that suggest the species' extent of occurrence is considerably broader than previously realised and that it is likely to occupy much of the Eyrean Province where suitable habitat persists. Previous records of the closely related O. genoveva (Hewitson, [1853]) from Western Australia are considered to be erroneous.

Recent surveys for the Eltham cooper butterfly Paralucia pyrodiscus lucida Crosby have revealed several previously unknown populations In the Wimmera (1), near Castlemalne (4) and near Bendlgo (1). Their significance is discussed in relation to the butterfly's conservation and management, including design of fuel reduction burning for occupied sited.

Fluoro-potassic-pargasite, ideally AK BCa 2 C(Mg 4Al) T(Si 6Al 2)O 22 WF 2, a new amphibole species, has been found in a skarn in the Tranomaro area, Madgascar. The sample used for the description of the new mineral species is a large single amphibole crystal, 4 mm × 2 mm × 2 cm in size, brownish-black with brownish-yellow phlogopite lamellae adhering to one face of the crystal. Fluoro-potassic- pargasite is brittle, has a Mohs hardness of 6.5 and a splintery fracture; it is non-fluorescent, has perfect {110} cleavage, no observable parting, and has measured and calculated densities of 3.46 and 3.151 g cm -3, respectively. In plane-polarized light, it is pleochroic, X = colourless to very pale grey, Y = very pale grey, Z = colourless; X ∧ a = 46.9° (in β obtuse), Y || b, Z ∧ c = 31.4° (in β acute). It is biaxial positive, α = 1.638(2), β = 1.641(2), γ = 1.653(2); 2V obs = 49.6(4)°, 2V calc = 53.4°. Fluoro-potassic-pargasite is monoclinic, space group C2/m, a = 9.9104(2), b = 17.9739(4), c = 5.3205(1) Å, β = 105.534(2)°, V = 913.11(6) Å 3, Z = 2. The eight strongest lines in the X-ray powder-diffraction pattern are [d in Å (I)(hkl)]: 3.133(100)(310), 3.270(55)(240), 2.809(47)(330), 8.413(45)(110), 2.698(39)(151), 3.374(31)(131), 2.934(29)(221) and 1.647(29)(461). Electron microprobe analysis gives SiO 2 40.20, Al 2O 3 17.61, TiO 2 0.46, FeO 1.96, Fe 2O 3 2.51, MgO 16.95, MnO 0.05, CaO 13.18, Na 2O 0.99, K 2O 3.72, F 2.75, H 2O calc 0.77, sum 99.99 wt.%. The formula unit, calculated on the basis of 24 (O,OH,F) with (OH + F) = 2 - (2 × Ti), is A(K 0.69Na 0.28Ca 0.04) Σ= 1.01 BCa 2.00 C(Mg 3.64Fe 2+ 0.24Mn 0.01Al 0.79Fe 3+ 0.27Ti 0.05) Σ=5.00 T(Si 5.80Al 2.20) Σ=8.00O 22 W[F 1.26(OH) 0.74] Σ=2.00. The mineral species and name have been approved by the IMA CMNMC (IMA 2009-091). © 2010 Mineralogical Society.

The purpose of this paper is to clarify and resolve the nomenclature of Ogyris halmaturia (Tepper, 1890), a nationally threatened butterfly which has had a long and complex nomenclatural history. This complexity has arisen because: (1) the species group name halmaturia was based on a mixed series comprising two different species; (2) historically at least six authors have attempted to resolve the nomenclature of halmaturia, but most failed to render a valid and unambiguous lectotype designation; (3) one of these authors (N.B. Tindale) made a particularly confusing lectotype designation in 1923; and (4) introduction of the name Ogyris waterhouseri (Bethune-Baker, 1905). The proposal to treat O. waterhouseri as a junior synonym of O. halmaturia is accepted. We argue that Tindale made the first valid and unambiguous lectotypification in 1923. Consequently, we propose, with the intention of bringing closure to this matter, that O. halmaturia is the senior synonym of O. waterhouseri and that Tepper's syntype 'female' is the lectotype male of O. halmaturia. Attention is drawn to ambiguity in Article 74.5 (lectotype designation made before 2000) in the most recent edition of the International Code of Zoological Nomenclature.

Patterns of distribution, key biometric parameters and home range extent were determined for hawksbill turtles at Lighthouse Reef Atoll (LRA), Belize over two field seasons (16days, 2009; 30days, 2010). Relative abundance was determined using 49 sightings transects (≈1km) distributed across the atoll and of all turtles encountered (n=68), 91% were immature (CCLmin≤65cm). Habitat type was significantly correlated with abundance, with more turtles encountered on the coral reef than in the lagoon (GzLMM, Χ2 2=6.85, p<0.05; CPUE reef=1.41turtlesh-1, CPUE lagoon=0.62turtlesh-1). Hawksbills were also significantly more abundant within protected areas (GzLMM, Χ2 1=8.69, p<0.05; CPUE Blue Hole Natural Monument (BHNM)=2.96turtlesperson-1h-1; CPUE Half Moon Caye Natural Monument (HMCNM)=2.34turtlesh-1; outside boundaries=0.88 turtlesh-1). Of 26 captures, 19 focal individuals were equipped with ultrasonic transmitters for active acoustic telemetry, and tracked for 6-25days (n=10, 2009; n=9, 2010). Spatial habitat utilisation was found to be highly variable, with large areas of overlap between distinct home ranges. Home range averaged 31.2ha±32.6 (range 5.1-111.3ha) for the juveniles that were successfully tracked (n=15), with maximum displacement in the order of 1.8km±1.0 (range 0.5-4.0km) and net displacement at 1.2km±0.9. This offshore atoll constitutes an important developmental habitat for the regional population and although our tracking durations were limited, home range of juvenile hawksbills at this site is significantly more expansive than that documented elsewhere. © 2011.
