ANATOMY OF JUNGA TRIMAMILLATA PAMPIGLIONE Er AL., 2002 (INSECTA, SlPHONAPTERA, TUNGIDAE) AND DEVELOPMENTAL PHASES OF THE GRAVID FEMALE

摘要

This paper deals with some internal anatomical features observed in histological sections and freshly dissected mounts of Tunga trimamillata, a Siphonaptera recently discovered in Andean regions of Ecuador from several mammals, including man It waspossible to study in males and also non-gravid and gravid females, the location and anatomy of several organs not previously described for this species: the testes, epididymis, ganglia, Malpighian tubules, eyes, rectal ampulla with one of its pads and structures which could be interpreted as midgut diverHcula, whose presence has not been recorded in the Siphonaptera. The process of neosomy in the female during pregnancy is illustrated by photographs of the consecutive developmental phases, taken at thestereomicroscope Furthermore, some details of the exoskeleton, spermatheca during different phases of pregnancy of the gravid female and the presence of a foreign body (parasite) within the haemocoel have been displayed in specimens cleared with Hoyer'smedium.
