It is distinguished from remaining congeners by the following combination of characters： adult size （SVL females 68-69 mm）, tail length/SVL ratio 226%-239%, HW/SVL ratio 17%-18%; FLL/SVL ratio 41%43%; HLL/SVL ratio 72%-73%; 7-9 supralabials, 7-9 infralabials, 54-56 middorsal scales, 20-22 lamellae under finger IV, 24-26 lamellae under toe IV, 1 scale between nasal and supralabials; tympanum concealed; absence of transverse gular fold. The geographical distribution of Japalura genus in general and of a new species in particular is discussed.展开更多

This new genus is named Laevispinereis. Its brief characters are as follows: oral ring of proboscis has papillae, maxillary ring has conical paragnaths; the peristomium greatly expands into a collar; notosetaes are homogomph spinigers, neurosetaes are homogomph spinigers and homogomph falcigers; tip of spinigers setae with minute serratures and smooth on side. The type of genus is Laevispinereis fujianensis sp. nov., it has conical paragnaths on maxillary ring of proboscis: I has Ⅰ; Ⅱ has 6-7: Ⅲ has 12;Ⅳ has 6-7.展开更多

It belongs to orthorhombic space group P212121 with a = 7.7372（15）A, b = 12.844（3） A, c -- 4.9062（10） A, V = 487.57（17） A^3, Z = 4. The final full-matric least-square refinement on F2 converged with R1 = 0.0495 and wR2 = 0.0992 for 704 observed reflections [I≥2σ（I）]. Lisiguangite is the isomorph of known CuNiSbS3 and CuNiBiS3. Pt^2＋ and Bi^3＋ have the distorted octahedral coordination enviroments composed of two metal and four S and Cu^＋2 has a distorted tetrahedrai coordination environment with four S atoms. Each S atom is surrounded by four metals to give a tetrahedral environment. The crystal structure is a complex 3 dimensional network.展开更多
