No full textArna bicostata Wang, Wang & Fan sp. nov. (Figs. 3–4, 28, 42) Diagnosis. Forewing length 10–14 mm. Forewing yellow, with two pale transverse lines medially; hindwing pale yellow. Description. Male and female. Vertex covered with pale yellow scales. Labial palpus short, upturned. Thorax and tegulae yellow. Forewing yellow, with a deep yellow band between two pale transverse lines medially, the band shaded grey in some specimens; venation with R 2, R 3, R 4 and R 5 stalked, R 2 branching off more distally than R 5, M 1 arising from upper angle of distal cell, M 3 from under angle of distal cell, M 2, M 3 and CuA 1 isolated, CuA 1 parallel to CuA 2. Hindwing paler yellow; venation with Rs stalked with M 1 at basal 1 / 4, M 2 arising from near under angle of distal cell, M 3 and CuA 1 short stalked. Male genitalia (Fig. 28): Uncus broad, apically divided in the dorso-ventral plane, triangular at apex of dorsal part; valva narrowed from apex of sacculus to costa; saccus small; aedeagus straight. Female genitalia (Fig. 42): Apophysis anterioris almost as long as apophysis posterioris, but thicker than the latter; ostium U-shaped; base of ductus inflated, lightly sclerotized; signum absent. Type material: Holotype: 3, Nanling National Nature Reserve, Guangdong, 7.V. 2009, leg. H.S. Wang. Paratypes: 4 3, 2 Ƥ, same data as the holotype; 2 3, same locality, 1.VI. 2006, leg. L.S. Chen, M. Wang. Distribution. China (Guangdong). Etymology. The specific name is derived from Latin, “bicostatus,” referring to the forewing with two pale lines medially. Remarks. The genus Arna Walker was reviewed by Holloway (1999) who reported 12 species. A Chinese species Euproctis pentamaculata described by Chao (1984) should also belong to this genus according to the male genitalia illustrated in his Fig. 230, along with A. pseudoconspersa (Strand) and the new species. As a result, 15 species of the genus are now recorded. The new species is similar to Arna bipunctapex, but can be easily separated from the latter by the following characters: forewing yellow with two pale transverse median lines; hindwing pale yellow; uncus less acute at apex of dorsal part, valva with shorter protrusion at apex of costa; female with a smaller ostium.Published as part of Wang, Houshuai, Wang, Min & Fan, Xiaoling, 2011, Notes on the tribe Nygmiini (Lepidoptera: Erebidae: Lymantriinae) from Nanling National Nature Reserve, with description of a new species, pp. 57-68 in Zootaxa 2887 on page 58, DOI: 10.5281/zenodo.20082

Ground colour sandy yellow, with abundant white or ash grey suffusion giving to moths a characteristic appearance. Wing pattern dark grey, prominent, submarginal field of the fore wing is covered with dark yellowbrown to chestnut scales whereas in hind wing it is brighter dark yellow to ochre-yellow. Wing serration distinct in hind wing, but marginal teeth are short and massive, forming sometimes very short bifurcate tail; in fore wing, medial projection may be double and the falcate part is smooth. Female similarly patterned, a bit darker, with the same kind of serration and a short bifurcate tail. Male genitalia (Fig. 26). Uncus lobes curved, lyre-shaped, with rounded apices; valvae short and broad; harpe strong, rather short and covered with dense spines on its distal third; right apical spur rather slender and pointed. Female genitalia as illustrated (Fig. 28). Diagnosis. Small size, contrasting ‘grey-scaled’ coloration, prominent wing pattern and short but distinct wing serration makes identification of the species rather easy. From the similar and sometimes sympatric O. yandu it differs being paler, a bit smaller, with shorter wing serration. Bionomics. The population of the species of the type locality is native to montaine forests where it inhabits altitudes of 1300–2600 m but more commonly 1500–1800 m, and is on the wing from late April to early September, develops 1–2 generation(s) depending on the altitude. Lowland populations (of Hunan, Guangdong, Hainan) are known develop two generations per season and is known from May to August. Distribution (Fig. 34). Mountains of Shaanxi, Jiangxi, Hubei, also known from N and NW Sichuan, Hunan, Guangdong and Hainan. PLATE 4. Figs 30–33. Biotopes. 30.

Identification of transformed grain boundaries and reconstruction of the prior grains from EBSD data in pure Ti and ?-Ti alloys
No full textWhen Ti is cooled rapidly from the ? region, the martensitic ? ? ? transformation occurs. The transformed microstructure will be made up ? phase grains, and the original structure of prior ? grains is no longer evident from optical microscopy or electron microscopy. This paper demonstrates a way to identify the transformation grain boundaries and accordingly reconstruct the prior grain structure through the use of electron backscattering diffraction on a scanning electron microscope. The approach is demonstrated for Ti and ?-Ti alloy, and it is thought to be applicable to other alloys such as in iron, zirconium
A comparison of grain size determination by light microscopy and EBSD analysis
Full text linkThis study shows that the accuracy of optical microscopy analysis of grain size depends on sample preparation techniques, etching procedures and materials, where the visibility of a boundary is a function of the techniques used, and the microstructure components on or close to the boundary. Optical examination of grain size does not always give the same information achieved by EBSD analysis. Fully automatic measurements of grain size by EBSD provides more accurate measurements than conventional optical imaging methods and yields smaller average grain size because EBSD has an advantage over the optical examination in better imaging smaller grains and its result is not dependent on etching and imaging techniques
