  • Gli Oniscidea sono l'unico gruppo di Crostacei completamente terrestri e costituiscono uno dei più interessanti esempi della transizione dalla vita acquatica alla vita terrestre: nelle forme meglio adattate all'ambiente subaereo sono presenti strutture respiratorie (le cosiddette pseudotrachee o polmoni pleopodali) a diverso grado di specializzazione. In questo articolo viene analizzato, per la prima volta, l'apparato respiratorio di un taxon, gli Eubelidae, che costituisce l'elemento più caratteristico e cospicuo (53 generi e ca 240 specie) della Regione Afrotropica: oltre alla descrizione morfologica dei vari tipi di polmoni è stato discusso il loro significato adattativo. Infine sono stati discussi l'evoluzione dei vari tipi di polmoni e il loro significato filogenetico. (literal)

Abstract
  • The morphology of the respiratory apparatus in the pleopodal lungs of the family Eubelidae was investigated. The family is a monophyletic group including more than 240 species in 53 genera (three of which are nomina dubia), mostly distributed in the Afrotropical Region (tropical Africa and Arabian Peninsula). In all the Eubelidae, except for the monospecific genus Parelumoides and two species of the genus Elumoides, the exopods of pleopods have lungs. All the pulmonary morphologies present in the entire suborder Oniscidea are found: 1) uncovered lungs, composed of a pleated respiratory surface, directly exposed to the air (Atracheodillo-type) or partially enclosed within the appendage (Synarmadilloides-type); 2) covered lungs with several spiracles and respiratory trees, housed within the appendages, with spiracles surrounded by a specialized, nonrespiratory, structure (perispiracular area) (Eubelum- and Somaloniscus-types); 3) covered lungs with only one spiracle, with or without perispiracular area, and one respiratory tree (Aethiopopactes- and Periscyphis-types), which in taxa with Periscyphis-type lung crosses the insertion of the appendage and penetrates into the pleon with bundles of respiratory tubules. The evolution of the various types of lungs is discussed. It is concluded that the two main evolutionary lines, i.e., uncovered lungs and covered lungs, originated independently from an ancestral respiratory structure--the semilunar area. A first mechanism of development of the semilunar area by folding of its surface produced the Atracheodillo-type (all folds coplanar with the surface of the exopod) and Synarmadilloides-type (folds partly coplanar and partly intraflexed inside the exopod) uncovered lungs. A second mechanismof development by tubular invagination of the cuticle of the semilunar area produced the polyspiracular Eubelum-type lungs (numerous arborescent invaginations) and the monospiracular Aethiopopactes-type lungs (only one arborescent invagination), probably passing through a common intermediate pattern. Fromthe common pattern, both the polyand monospiracular types would have inherited the characteristic concave cell arrangement of the perispiracular area. The Somaloniscus-type and Periscyphis-type lungs are forms specialized for arid environments, directly derived fromthe Eubelum-type and Aethiopopactes-type, respectively. (literal)
