ABSTRACT
The phylogenetic relationships of the families Cheilodactylidae and Latridae, plus related taxa, are examined from a detailed osteological perspective. The monophyly of each family is re-evaluated and a new classification is proposed on the basis of phylogenetic relationships. A phylogenetic analysis of characters in 67 transformation series showed Latridae to comprise a monophyletic group nested within cheilodactylids. Cheilodactylidae was non-monophyletic, but rather was formed by a clade including Cheilodactylus fasciatus and C. pixi having a sister relationship with a second clade comprising remaining cheilodactylids and latrids. A new classification is proposed, Cheilodactylidae, including only genus Cheilodactylus, and Latridae, including six genera (Latris, Nemadactylus, Mendosoma, Goniistius, Latridopsis and Dactylophora).

Nowadays, ca. 176,640 tons/year of silicon (Si) (>4N) is manufactured for Si wafers used for semiconductor industry. The production of the highly pure Si wafers inevitably includes very high-temperature steps at 1400-2000 °C, which is energy-consuming and environmentally unfriendly. Inefficiently, ca. 45-55% of such costly Si is lost simply as sawdust in the cutting process. In this work, we develop a cost-effective way to recycle Si sawdust as a high-performance anode material for lithium-ion batteries. By a beads-milling process, nanoflakes with extremely small thickness (15-17 nm) and large diameter (0.2-1 µm) are obtained. The nanoflake framework is transformed into a high-performance porous structure, named wrinkled structure, through a self-organization induced by lithiation/delithiation cycling. Under capacity restriction up to 1200 mAh g-1, the best sample can retain the constant capacity over 800 cycles with a reasonably high coulombic efficiency (98-99.8%).
