Abstract：
:The authors' purpose will be here to underline the continuity of the adaptative processes that make Homo sapiens, sometimes a brilliant inventor, sometimes a mere imitator, forging tools already conceived by Nature itself.

杂志文章abstract：:A new genus and species of stick insect is described and figured from Mount Halcon, on the Philippine island of Mindoro. Conlephasma enigma gen. et sp. n. is a stout, flightless, and apparently ground-dwelling species with vivid integumental colors. When disturbed, specimens spray a defensive secretion from the protho...
