    • found: Work cat.: Lourenço, W.R. A new case of duplication of the metasoma and telson in the scorpion Euscorpius flavicaudis (DeGeer, 1778) (Euscorpiidae), 2010.
    • found: Wikipedia, Nov. 28, 2010(The metasoma is the posterior part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the mesosoma. In insects, it contains most of the digestive tract, respiratory system, and circulatory system, and the apical segments are typically modified to form genitalia. In scorpions, the metasoma is the tail. In other arachnids such as spiders, the mesosoma is fused with the metasoma to form the opisthosoma.)
    • found: Encyc. Britannica online, Nov. 28, 2010(under arachnid structures: There are many modifications of the cephalothorax and abdomen. Among the scorpions the abdomen is subdivided into the mesosoma, or preabdomen, and the metasoma, or postabdomen, which is mobile and more slender. Similar arrangements are found among whip scorpions, schizomids, and ricinuleids.)
    • found: Allaby, M. A dictionary of zoology, 1999, via Encyclopedia.com website, Nov. 28, 2010(metasoma: 1. In invertebrates whose body is divided into sections (e.g. Lophophorata and Hemichordata), the "trunk" that lies behind the protosoma and mesosoma. 2. In Hymenoptera, those segments that lie behind the petiole (i.e. the abdomen from the second segment).)
