Resumo

Background: The orange-spined hairy dwarf porcupine (Sphiggurus villosus) is a mammal found in Brazil, Venezuela, Guyanas and Bolivia. Its dorsum is yellowish brown and presents a great number of spines. There are no spines in the belly area, which is covered with softer fur. It can host ticks and louses, hemoparasites and endoparasites. This paper aimed to describe the lung lobation and the bronchial distribution of the orange-spined hairy dwarf porcupine.Materials, Methods & Results: The lungs of two orange-spined hairy dwarf porcupines, ran over by cars and with no damage in the viscerae, were used in the study. Animals were set with intramuscular and intravisceral injections of a 10% formaldehyde solution and further dissected. The right lung was bigger than the left one and presented cranial, middle, caudal and accessory lobes, and the cranial lobe was bilobated in cranial and caudal portions. The left lung presented cranial and caudal lobes, and the former was subdivided into cranial and caudal portions. The right main bronchus divided into three bronchi, one to the cranial, one to the middle and one to the caudal and accessory lobes. The right lobar bronchus gave origin to five segmental bronchi to the cranial portion and three segmental bronchi to the caudal portion; the middle lobar bronchus originated four segmental bronchi; the accessory lobe bronchus was origina
