Myriapoda

[‚mir·ē′äp·ə·də]
(invertebrate zoology)
Informal designation for those mandibulate arthropods having two body tagmata, one pair of antennae, and more than three pairs of adult ambulatory appendages.

Myriapoda

 

the general name for the following four classes of terrestrial arthropods: Chilopoda, Diplopoda, Symphyla, and Pauropoda. Formerly the four classes were considered to be a single class. The bodies of myriapods consist of a head and a more or less long segmented trunk. There is one pair of antennae, and there are legs on all (or almost all) trunk segments. These arthropods comprise about 11,000 species; in the USSR there are approximately 1,000 species. Myriapods live in soil, on the forest floor, and in rotten wood. They feed on decaying plant remains (Diplopoda and Symphyla) and on fungous mycelium (Pauropoda); some are predators (Chilopoda).

Ahora, como parafrasis a lo que Adis (1989) apunto en su clave ilustrada de los Myriapoda neotropicales, el desafio que se plantea a los taxonomos profesionales, aficionados o diletantes es complementar este trabajo con guias que permitan la determinacion de generos, o hasta especies, dentro de cada familia.

De los artropodos recuperados, 93% y 7% pertenecen a las Clases Insecta y Myriapoda, respectivamente.
Los Collembola ocuparon el segundo grupo en abundancia, con el 43,10% (Tabla 2); en tercer lugar se encuentran los insectos, con el 4,29%, y dentro de ellos, los Coleoptera fueron los de mayor representacion, seguidos de Psocoptera, Thysanoptera, Hemiptera e Hymenoptera; en cuarto lugar se encuentra Gastropoda (2,42%), seguido de Arachnida (1,76%), donde Opilionida resulto el mas abundante; posteriormente se encuentran Myriapoda (0,52%) y Oligochaeta (0,46%) (Tabla 2).
